Close Margins in Oral Cancers: Implication of Close Margin Status in Recurrence and Survival of pT1N0 and pT2N0 Oral Cancers Tue, 11 Nov 2014 11:54:24 +0000 http://www.hindawi.com/journals/ijso/2014/545372/ Introduction. Among all prognostic factors, “margin status” is the only factor under clinician’s control. Current guidelines describe histopathologic margin of >5 mm as “clear margin” and 1–5 mm as “close margin.” Ambiguous description of positive margin in the published data resulted in comparison of microscopically “involved margin” and “close margin” together with “clear margin” in many publications. Authors attempted to compare the outcome of close and clear margins of stage I and stage II squamous cell carcinoma of oral cavity to investigate the efficacy of description of margin status. Patients and Methods. Historical cohorts of patients treated between January 2010 and December 2011 at tertiary cancer hospital were investigated and filtered for stage I and stage II primary squamous cell carcinomas of oral cavity. Patients with margin status of tumor at margin or within 1mm from cut margin were excluded and analyzed in multivariate logistic regression model for locoregional recurrences and Cox regression for overall survival. Results. A total of 104 patients fulfilled the abovementioned criteria, of whom 36 were “clear margin” and 68 were “close margin” with median period of follow-up of 39 months. There was no significant difference in locoregional recurrence (P value: 0.0.810) and survival (P value: 0.0.851) among “close margin” and “clear margin” patients.

Emergency Surgery for Metastatic Melanoma Tue, 28 Oct 2014 06:40:32 +0000 http://www.hindawi.com/journals/ijso/2014/987170/ Visceral metastases from malignant melanoma (stage M1c) confer a very poor prognosis, as documented on the most recent revised version of the TNM/AJCC staging system. Emergency surgery for intra-abdominal complications from the disease is rare. We report on our 5-year single institution experience with surgical management of metastatic melanoma to the viscera in the emergent setting. From 2009 to 2013, 14 patients with metastatic melanoma were admitted emergently due to an acute abdomen. Clinical manifestations encompassed intestinal obstruction and bleeding. Surgical procedures involved multiple enterectomies with primary anastomoses in 8 patients, and one patient underwent splenectomy, one adrenalectomy, one right colectomy, one gastric wedge resection, one gastrojejunal anastomosis, and one transanal debulking, respectively. The 30-day mortality was 7 percent. Median follow-up was 14 months. Median overall survival was 14 months. Median disease free survival was 7.5 months. One-year overall survival was 64.2 percent and 2-year overall survival was 14.2 percent. Emergency surgery for metastatic melanoma to the viscera is rare. Elective curative surgery combined with novel cytotoxic systemic therapies is under investigation in an attempt to grant survival benefit in melanoma patients with visceral disease.

Evaluation of a New Modification of Pancreaticogastrostomy after Pancreaticoduodenectomy: Anastomosis of the Pancreatic Duct to the Gastric Mucosa with Invagination of the Pancreatic Remnant End into the Posterior Gastric Wall for Patients with Cancer Head of Pancreas and Periampullary Carcinoma in terms of Postoperative Pancreatic Fistula Formation Tue, 16 Sep 2014 00:00:00 +0000 http://www.hindawi.com/journals/ijso/2014/490386/ Background/Objectives. Postoperative pancreatic fistula (POPF) remains the main problem after pancreaticoduodenectomy and determines to a large extent the final outcome. We describe a new modification of pancreaticogastrostomy which combines duct to mucosa anastomosis with suturing the pancreatic capsule to posterior gastric wall and then invaginating the pancreatic remnant into the posterior gastric wall. This study was designed to assess the results of this new modification of pancreaticogastrostomy. Methods. The newly modified pancreaticogastrostomy was applied to 37 consecutive patients after pancreaticoduodenectomy for periampullary cancer (64.86%) or cancer head of the pancreas (35.14%). Eighteen patients (48.65%) had a soft pancreatic remnant, 13 patients (35.14%) had firm pancreatic remnant, and 6 patients (16.22%) had intermediate texture of pancreatic remnant. Rate of mortality, early postoperative complications, and hospital stay were also reported. Results. Operative mortality was zero and morbidity was 29.73%. Only three patients (8.11%) developed pancreatic leaks; they were treated conservatively. Eight patients (16.1%) had delayed gastric emptying, one patient (2.70%) had minor hemorrhage, one patient (2.70%) had biliary leak, and four patients (10.81%) had superficial wound infection. Conclusions. The new modified pancreatogastrostomy seems safe and reliable with low rate of POPF. However, further prospective controlled trials are essential to support these results.

Minimally Invasive Esophagectomy for Esophageal Cancer: The First Experience from Pakistan Sun, 20 Jul 2014 09:10:51 +0000 http://www.hindawi.com/journals/ijso/2014/864705/ Background. Two common procedures for esophageal resection are Ivor Lewis esophagectomy and transhiatal esophagectomy. Both procedures have high morbidity rates of 20–46%. Minimally invasive esophagectomy has been introduced to decrease morbidity. We report initial experience of MIE to determine the morbidity and mortality associated with this procedure during learning phase. Material and Methods. Patients undergoing MIE at our institute from January 2011 to May 2013 were reviewed. Record was kept for any morbidity and mortality. Descriptive statistics were presented as frequencies and continuous variables were presented as median. Survival analysis was performed using Kaplan Meier curves. Results. We performed 51 minimally invasive esophagectomies. Perioperative morbidity was in 16 (31.37%) patients. There were 3 (5.88%) anastomotic leaks. We encountered 1 respiratory complication. Reexploration was required in 3 (5.88%) patients. Median operative time was 375 minutes. Median hospital stay was 10 days. The most frequent long-term morbidity was anastomotic narrowing observed in 5 (9.88%) patients. There were no perioperative mortalities. Our mean overall survival was 37.66 months (95% confidence interval 33.75 to 41.56 months). Mean disease-free survival was 24.43 months (95% CI 21.26 to 27.60 months). Conclusion. Minimally invasive esophagectomy, when performed in the learning phase, has acceptable morbidity and mortality.

Prognostic Factors and Survival in Patients Treated Surgically for Recurrent Metastatic Uterine Leiomyosarcoma Sun, 22 Jun 2014 07:37:14 +0000 http://www.hindawi.com/journals/ijso/2014/919323/ Background. Uterine leiomyosarcoma (LMS) is a rare diagnosis, which is seldom cured when it recurs with metastatic disease. We evaluated patients who present with first time recurrence treated surgically to determine prognostic factors associated with long-term survival. Methods. Over a 16-year period, 41 patients were operated on for recurrent uterine sarcoma. Data examined included patient age, date of initial diagnosis, tumor histology, grade at the initial diagnosis, cytopathology changes in tumor activity from the initial diagnosis, residual tumor after all operations, use of adjuvant therapy, dates and sites of all recurrences, and disease status at last followup. Results. 24 patients were operated for first recurrence of metastatic uterine LMS. Complete tumor resection with histologic negative margins was achieved in 16 (67%) patients. Overall survival was significantly affected by the FIGO stage at the time of the initial diagnosis, the ability to obtain complete tumor resection at the time of surgery for first time recurrent disease, single tumor recurrence, and recurrence greater than 12 months from the time of the initial diagnosis. Median disease-free survival was 14 months and overall survival was 27 months. Conclusion. Our findings suggest that stage 1 at the time of initial diagnosis, recurrence greater than 12 months, isolated tumor recurrence, and the ability to remove ability to perform complete tumor resection at the time of the first recurrence can afford improved survival in selected patientsat the time of the first recurrence can afford improved survival in selected patients.

Cytoreductive Surgery and HIPEC for Peritoneal Carcinomatosis in the Elderly Wed, 16 Apr 2014 08:33:58 +0000 http://www.hindawi.com/journals/ijso/2014/987475/ Background. The combined treatment of peritoneal carcinomatosis with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is a rigorous surgical treatment, most suitable for young and good performance status patients. We evaluated the outcomes of elderly patients undergoing CRS and HIPEC for peritoneal carcinomatosis with careful perioperative care. Methods. All consecutive patients 70 years of age or older who were treated for peritoneal carcinomatosis over the past five years were included. Primary outcomes were perioperative morbidity and mortality. Secondary outcomes were disease-free survival and overall survival. Results. From a pool of 100 patients, with a diagnosis of PC who underwent CRS and HIPEC in our center, we have included 30 patients at an age of 70 years or older and the results were compared to the patients younger than 70 years. The total morbidity rate was 50% versus 41.5% in the group younger than 70 years (NSS). The mortality rate was 3.3% in the elderly group versus 1.43% in the younger group (NSS). Median overall survival was 30 months in the older group versus 38 months in the younger group. Conclusion. Cytoreductive surgery and HIPEC for peritoneal carcinomatosis may be safely performed with acceptable morbidity in selected elderly patients. J. D. Spiliotis, E. Halkia, V. A. Boumis, D. T.

Incisional Surgical Site Infection after Elective Open Surgery for Colorectal Cancer Thu, 27 Mar 2014 09:03:18 +0000 http://www.hindawi.com/journals/ijso/2014/419712/ Background. The purpose of this study was to clarify the incidence and risk factors for incisional surgical site infections (SSI) in patients undergoing elective open surgery for colorectal cancer. Methods. We conducted prospective surveillance of incisional SSI after elective colorectal resections performed by a single surgeon for a 1-year period. Variables associated with infection, as identified in the literature, were collected and statistically analyzed for their association with incisional SSI development. Results. A total of 224 patients were identified for evaluation. The mean patient age was 67 years, and 120 (55%) were male. Thirty-three (14.7%) patients were diagnosed with incisional SSI. Multivariate analysis suggested that incisional SSI was independently associated with TNM stages III and IV (odds ratio [OR], 2.4) and intraoperative hypotension (OR, 3.4). Conclusions. The incidence of incisional SSI in our cohort was well within values generally reported in the literature. Our data suggest the importance of the maintenance of intraoperative normotension to reduce the development of incisional SSI.

The Aetiology of Delay to Commencement of Adjuvant Chemotherapy following Colorectal Resection Mon, 17 Mar 2014 07:07:58 +0000 http://www.hindawi.com/journals/ijso/2014/670212/ Purpose. Timely administration of adjuvant chemotherapy following colorectal resection is associated with improved outcome. We aim to assess the factors which are associated with delay to adjuvant chemotherapy in patients who underwent colorectal resection as part of an enhanced recovery protocol. Method. A univariate and multivariate analysis of patient data collected as part of a prospectively maintained database of colorectal cancer patients between 2007 and 2012. Results. 166 patients underwent colorectal resection followed by adjuvant chemotherapy. Median postoperative hospital stay was 6 days, and time to commencement of adjuvant chemotherapy was 50 days. Longer inpatient stay correlated with increased time to adjuvant chemotherapy (). Factors found to be independently associated with duration of hospital stay and time to commencement of adjuvant chemotherapy included stoma formation (), anastaomotic leak (), and preoperative albumin (). The use of laparoscopic surgery was associated with shorter time to adjuvant chemotherapy but did not reach significance (). Conclusion. A number of independent variables associated with delay to adjuvant therapy previously not described have been identified. Further work may be required to elucidate the effect that these variables have on long-term outcome. G. S. Simpson, R. Smith, P. Sutton, A. Shekouh, C. McFaul, M. Johnson, and D.

Regional Failures after Selective Neck Dissection in Previously Untreated Squamous Cell Carcinoma of Oral Cavity Tue, 11 Mar 2014 13:13:44 +0000 http://www.hindawi.com/journals/ijso/2014/205715/ Aim. To share experience with regional failures after selective neck dissection in both node negative and positive previously untreated patients diagnosed with squamous cell carcinoma of the oral cavity. Patients and Methods. Data of 219 patients who underwent SND at Shaukat Khanum Cancer Hospital from 2003 to 2010 were retrospectively reviewed. Patient characteristics, treatment modalities, and regional failures were assessed. Expected 5-year regional control was calculated and prognostic factors were determined. Results. Median follow-up was 29 (9–109) months. Common sites were anterior tongue in 159 and buccal mucosa in 22 patients. Pathological nodal stage was N0 in 114, N1 in 32, N2b in 67, and N2c in 5 patients. Fourteen (6%) patients failed in clinically node negative neck while 8 (4%) failed in clinically node positive patients. Out of 22 total regional failures, primary tumor origin was from tongue in 16 (73%) patients. Expected 5-year regional control was 95% and 81% for N0 and N+ disease, respectively (). Only 13% patients with well differentiated, T1 tumors in cN0 neck were pathologically node positive. Conclusions. Selective neck dissection yields acceptable results for regional management of oral squamous cell carcinoma. Wait and see policy may be effective in a selected subgroup of patients.

The Treatment of Peritoneal Carcinomatosis in Advanced Gastric Cancer: State of the Art Mon, 17 Feb 2014 16:18:07 +0000 http://www.hindawi.com/journals/ijso/2014/912418/ Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer death in the world; 53–60% of patients show disease progression and die of peritoneal carcinomatosis (PC). PC of gastric origin has an extremely inauspicious prognosis with a median survival estimate at 1–3 months. Different studies presented contrasting data about survival rates; however, all agreed with the necessity of a complete cytoreduction to improve survival. Hyperthermic intraperitoneal chemotherapy (HIPEC) has an adjuvant role in preventing peritoneal recurrences. A multidisciplinary approach should be empowered: the association of neoadjuvant intraperitoneal and systemic chemotherapy (NIPS), cytoreductive surgery (CRS), HIPEC, and early postoperative intraperitoneal chemotherapy (EPIC) could increase the rate of completeness of cytoreduction (CC) and consequently survival rates, especially in patients with Peritoneal Cancer Index (PCI) ≤6. Neoadjuvant chemotherapy may improve survival also in PC from GC and adjuvant chemotherapy could prevent recurrence. In the last decade an interesting new drug, called Catumaxomab, has been developed in Germany. Two studies showed that this drug seems to improve progression-free survival in patients with GC; however, final results for both studies have still to be published.

Supraclavicular Artery Flap for Head and Neck Oncologic Reconstruction: An Emerging Alternative Sun, 29 Dec 2013 14:01:40 +0000 http://www.hindawi.com/journals/ijso/2013/658989/ Aim. Head and Neck oncologic resections often leave complex defects which are challenging to reconstruct. The need of the hour is a versatile flap which has the advantages of both a regional flap (viz. reliable and easy to harvest) and a free flap (thin, pliable with good colour match). In this a study we assessed the usefulness of the supraclavicular artery flap in head and neck oncologic defects. Materials and Method. The flap was used as a pedicled fasciocutanous and was based on the transverse supraclavicular artery. We assessed this reconstructive option for complications as well as its and functional out comes. Results. Eleven cases underwent supraclavicular artery flap between 20011-2012 of which 5 were males and 6 females. Mean defect size was 5 cm × 6 cm. Nine donor sites were closed primarily and 1 required split skin grafting. We encountered one complete flap loss which was attributed to a band of constricting skin bridge over the vascular pedicle in a defect involving lateral third of midface. Two patient developed pharyngeocutaneous fistula (without flap loss) out of 3 patients who underwent augmentation pharyngoplasty post Near total laryngectomy. Conclusion. Supra clavicular artery flap is a thin versatile, reliable, easy to harvest, with good cosmetic and functional outcome at both ends (recipient and donor) for reconstructing head and neck oncologic defects.

Harmonic Scalpel versus Conventional Haemostasis in Neck Dissection: A Prospective Randomized Study Sun, 22 Dec 2013 12:00:12 +0000 http://www.hindawi.com/journals/ijso/2013/369345/ Purpose. The aim of this prospective randomized trial was to compare operative factors, postoperative outcomes, and surgical complications of neck dissection (ND) when using the harmonic scalpel (HS) versus conventional haemostasis (CH) (classic technique of tying and knots, resorbable ligature, and bipolar diathermy). Materials and methods. Sixty-one patients who underwent ND with primary head and neck cancer (HNSCC) resection were enrolled in this study and were randomized into two homogeneous groups: CH (conventional haemostasis with classic technique of tying and knots, resorbable ligature, and bipolar diathermy) and HS (haemostasis with harmonic scalpel). Outcomes of the study included operative time, intraoperative blood loss, drainage volume, postoperative pain, hospital stay, and incidence of intraoperative and postoperative complications. Results. The use of the HS reduced significantly the operating time, the intraoperative blood loss, the postoperative pain, and the volume of drainage. No significant difference was observed in mean hospital stay and perioperative, and postoperative complications. Conclusion. The HS is a reliable and safe tool for reducing intraoperative blood loss, operative time, volume of drainage and postoperative pain in patients undergoing ND for HNSCC. Multicenter randomized studies need to be done to confirm the advantages of this technique and to evaluate the cost-benefit ratio.

Diaphragmatic Peritonectomy versus Full Thickness Diaphragmatic Resection and Pleurectomy during Cytoreduction in Patients with Ovarian Cancer Wed, 18 Dec 2013 16:24:57 +0000 http://www.hindawi.com/journals/ijso/2013/876150/ Objectives. Compare the surgical morbidity of diaphragmatic peritonectomy versus full thickness diaphragmatic resection with pleurectomy at radical debulking. Design. Prospective cohort study at the Oxford University Hospital. Methods. All debulking with diaphragmatic peritonectomy and/or full thickness resection with pleurectomy in the period from April 2009 to March 2012 were part of the study. Analysis is focused on the intra- and postoperative morbidity. Results. 42 patients were eligible for the study, 21 underwent diaphragmatic peritonectomy (DP, group 1) and 21 diaphragmatic full thickness resection (DR, group 2). Forty patients out of 42 (93%) had complete tumour resection with no residual disease. Histology confirmed the presence of cancer in diaphragmatic peritoneum of 19 patients out of 21 in group 1 and all 21 patients of group 2. Overall complications rate was 19% in group 1 versus 33% in group 2. Pleural effusion rate was 9.5% versus 14.5% and pneumothorax rate was 14.5% only in group 2. Two patients in each group required postoperative chest drains (9.5%). Conclusions. Diaphragmatic surgery is an effective methods to treat carcinomatosis of the diaphragm. Patients in the pleurectomy group experienced pneumothorax and a higher rate of pleural effusion, but none had long-term morbidity or additional surgical interventions. P. N. J. Pathiraja, R.

Gastrointestinal Stromal Tumors Associated with Neurofibromatosis 1: A Single Centre Experience and Systematic Review of the Literature Including 252 Cases Mon, 09 Dec 2013 16:38:52 +0000 http://www.hindawi.com/journals/ijso/2013/398570/ Aims. The objectives of this study were (a) to report our experience regarding the association between neurofibromatosis type 1 (NF1) and gastrointestinal stromal tumors (GISTs); (b) to provide a systematic review of the literature in this field; and (c) to compare the features of NF1-associated GISTs with those reported in sporadic GISTs. Methods. We reported two cases of NF1-associated GISTs. Moreover we reviewed 23 case reports/series including 252 GISTs detected in 126 NF1 patients; the data obtained from different studies were analyzed and compared to those of the sporadic GISTs undergone surgical treatment at our centre. Results. NF1 patients presenting with GISTs had a homogeneous M/F ratio with a mean age of 52.8 years. NF1-associated GISTs were often reported as multiple tumors, mainly incidental, localized at the jejunum, with a mean diameter of 3.8 cm, a mean mitotic count of 3.0/50 HPF, and KIT/PDGFRα wild type. We reported a statistical difference comparing the age and the symptoms at presentation, the tumors’ diameters and localizations, and the risk criteria of the NF1-associated GISTs comparing to those documented in sporadic GISTs. Conclusions. NF1-associated GISTs seem to have a distinct phenotype, specifically younger age, distal localization, small diameter, and absence of KIT/PDGRFα mutations.

Sentinel Lymph Node Detection Using Laser-Assisted Indocyanine Green Dye Lymphangiography in Patients with Melanoma Sun, 08 Dec 2013 11:17:41 +0000 http://www.hindawi.com/journals/ijso/2013/904214/ Introduction. Sentinel lymph node (SLN) biopsy is a vital component of staging and management of multiple cancers. The current gold standard utilizes technetium 99 (tech99) and a blue dye to detect regional nodes. While the success rate is typically over 90%, these two methods can be inconclusive or inconvenient for both patient and surgeon. We evaluated a new technique using laser-assisted ICG dye lymphangiography to identify SLN. Methods. In this retrospective analysis, we identified patients with melanoma who were candidates for SLN biopsy. In addition to tech99 and methylene blue, patients received a dermal injection of indocyanine green (ICG). The infrared signal was detected with the SPY machine (Novadaq), and nodes positive by any method were excised. Results. A total of 15 patients were evaluated, with 40 SLNs removed. Four patients were found to have nodal metastases on final pathology. 100% of these 4 nodes were identified by ICG, while only 75% (3/4) were positive for tech99 and/or methylene blue. Furthermore, none of the nodes missed by ICG (4/40) had malignant cells. Conclusion. ICG dye lymphangiography is a reasonable alternative for locating SLNs in patients with melanoma. Prospective studies are needed to better ascertain the full functionality of this technique. Vikalp Jain, Brett T. Phillips, Nicole Conkling, and Colette Pameijer Copyright © 2013 Vikalp Jain et al.

Sun, 08 Dec 2013 09:15:00 +0000 http://www.hindawi.com/journals/ijso/2013/829050/ The American Society for Radiation Oncology (ASTRO) consensus statement (CS) provides guidelines for patient selection for accelerated partial breast irradiation (APBI) following breast conserving surgery. The purpose of this study was to evaluate recurrence rates based on ASTRO CS groupings. A single institution review of 238 early stage breast cancer patients treated with balloon-based APBI via balloon based brachytherapy demonstrated a 4-year actuarial ipsilateral breast tumor recurrence (IBTR) rate of 5.1%. There were no significant differences in the 4-year actuarial IBTR rates between the “suitable,” “cautionary,” and “unsuitable” ASTRO categories (0%, 7.2%, and 4.3%, resp., ). ER negative tumors had higher rates of IBTR than ER positive tumors. The ASTRO groupings are poor predictors of patient outcomes. Further studies evaluating individual clinicopathologic features are needed to determine the safety of APBI in higher risk patients. Moira K. Christoudias, Abigail E. Collett, Tari S.

Gastric Cancer in Young Patients Sat, 07 Dec 2013 11:00:50 +0000 http://www.hindawi.com/journals/ijso/2013/981654/ Aim. The aim of this study was to see the clinical, pathological, and demographic profile of young patients with stomach carcinoma besides association with p53. Patients and Methods. Prospective study of young patients with stomach carcinoma from January 2005 to December 2009. A total of 50 patients with age less than 40 years were studied. Results. Male female ratio was 1 : 1.08 in young patients and 2.5 : 1 in older patients. A positive family history of stomach cancer in the first degree relatives was present in 10% of young patients. Resection was possible only in 50% young patients. 26% young patients underwent only palliative gastrojejunostomy. The most common operation was lower partial gastrectomy in 68%. Amongst the intraoperative findings peritoneal metastasis was seen in 17.4% in young patients. 50% young patients presented in stage IV as per AJCC classification ( value .004; sig.). None of the patients presented as stage 1 disease in young group. Conclusion. Early detection of stomach carcinoma is very important in all patients but in young patients it is of paramount importance. Manzoor A. Dhobi, Khursheed Alam Wani, Fazl Qadir Parray, Rouf A.

Baseline Quality of Life Factors Predict Long Term Survival after Elective Resection for Colorectal Cancer Wed, 27 Nov 2013 11:24:28 +0000 http://www.hindawi.com/journals/ijso/2013/269510/ Background. Studies have shown an association between baseline quality of life (Qol) and survival in advanced cancers. The aim of this study was to investigate their predictive value in long term survival after elective colorectal cancer resection. Methods. A consecutive series of patients undergoing elective colorectal cancer surgery for nonmetastatic disease were recruited in 2003/04. Patients completed standardized quality of life questionnaires (HADS, FACTC, MRS, and PANAS) prior to and 6 weeks after surgery. Univariate (log-rank test) and multivariate analyses (Cox proportional hazards) were performed to predict long term survival. Results. Ninety-seven patients met the inclusion criteria. Sixty-five (67%) were male and the median age of the group was 70 years. Forty-six (47.5%) patients had died and the mean survival was 1,741 days (median 2159, range 9–2923 days). Preoperative mood rating scale and functional assessment of cancer therapy-colorectal FACT C emotional well-being and postoperative FACT C additional concerns were independent predictors of long term survival. Conclusion. Incorporating psychosocial measures in preoperative assessment of cancer patients could help to identify patients who require assessment with a view to implementing psychosocial interventions. These active interventions to maximize mood and well-being should form an integral part of multidisciplinary treatment in these patients. Abhiram Sharma, Leslie G. Walker, and John R. T.

Trail Overexpression Inversely Correlates with Histological Differentiation in Intestinal-Type Sinonasal Adenocarcinoma Mon, 07 Oct 2013 09:33:18 +0000 http://www.hindawi.com/journals/ijso/2013/203873/ Introduction. Despite their histological resemblance to colorectal adenocarcinoma, there is some information about the molecular events involved in the pathogenesis of intestinal-type sinonasal adenocarcinomas (ITACs). To evaluate the possible role of TNF-related apoptosis-inducing ligand (TRAIL) gene defects in ITAC, by investigating the immunohistochemical expression of TRAIL gene product in a group of ethmoidal ITACs associated with occupational exposure. Material and Methods. Retrospective study on 23 patients with pathological diagnosis of primary ethmoidal ITAC. Representative formalin-fixed, paraffin-embedded block from each case was selected for immunohistochemical studies using the antibody against TRAIL. Clinicopathological data were also correlated with the staining results. Results. The immunohistochemical examination demonstrated that poorly differentiated cases showed a higher percentage of TRAIL expressing cells compared to well-differentiated cases. No correlation was found with other clinicopathological parameters, including T, stage and relapses. Conclusion. The relationship between upregulation of TRAIL and poorly differentiated ethmoidal adenocarcinomas suggests that the mutation of this gene, in combination with additional genetic events, could play a role in the pathogenesis of ITAC.

Differentiated Thyroid Cancer: Indications and Extent of Central Neck Dissection—Our Experience Thu, 26 Sep 2013 10:59:39 +0000 http://www.hindawi.com/journals/ijso/2013/625193/ The aim of this retrospective study was to determine the rate of metastases in the central neck compartment and examine the morbidity and rate of recurrence in patients with differentiated thyroid cancer treated with or without a central neck dissection. Two hundred and fifteen patients undergoing total thyroidectomy with preoperative diagnosis of differentiated thyroid cancer, in the absence of suspicious nodes, were divided in two groups: those who underwent a thyroidectomy only (group A; ) and those who also received a central neck dissection (group B; ). Five cases (2.32%) of nodal recurrence were observed: 3 in group A and 2 in group B. Tumor histology was associated with a risk of recurrence: Hürthle cell-variant and tall cell-variant carcinomas were associated with a high risk of recurrence. Multifocality and extrathyroidal invasion also presented a higher risk, while smaller tumors were at lower risk. The results of this study suggest that prophylactic central neck dissection should be reserved for high-risk patients only. A wider use of immunocytochemical and genetic markers to improve preoperative diagnosis and the development of methods for the intraoperative identification of metastatic lymph nodes will be useful in the future for the improved selection of patients for central neck dissections.

Tumor Regression Grades: Can They Influence Rectal Cancer Therapy Decision Tree? Wed, 25 Sep 2013 10:19:53 +0000 http://www.hindawi.com/journals/ijso/2013/572149/ Background. Evaluating impact of tumor regression grade in prognosis of patients with locally advanced rectal cancer (LARC). Materials and Methods. We identified from our colorectal cancer database 168 patients with LARC who received neoadjuvant therapy followed by complete mesorectum excision surgery between 2003 and 2011: 157 received 5-FU-based chemoradiation (CRT) and 11 short course RT. We excluded 29 patients, the remaining 139 were reassessed for disease recurrence and survival; the slides of surgical specimens were reviewed and classified according to Mandard tumor regression grades (TRG). We compared patients with good response (Mandard TRG1 or TRG2) versus patients with bad response (Mandard TRG3, TRG4, or TRG5). Outcomes evaluated were 5-year overall survival (OS), disease-free survival (DFS), local, distant and mixed recurrence. Results. Mean age was 64.2 years, and median followup was 56 months. No statistically significant survival difference was found when comparing patients with Mandard TRG1 versus Mandard TRG2 (). Mandard good responders (TRG1 + 2) have significantly better OS and DFS than Mandard bad responders (TRG3 + 4 + 5) (OS ; DFS ). Conclusions. Mandard good responders had a favorable prognosis. Tumor response (TRG) to neoadjuvant chemoradiation should be taken into account when defining the optimal adjuvant chemotherapy regimen for patients with LARC. Marisa D.

The Postoperative Component of MAGIC Chemotherapy Is Associated with Improved Prognosis following Surgical Resection in Gastric and Gastrooesophageal Junction Adenocarcinomas Tue, 17 Sep 2013 13:35:39 +0000 http://www.hindawi.com/journals/ijso/2013/781742/ Aims. MAGIC chemotherapy has become the standard of treatment for patients undergoing curative resection for gastric and gastrooesophageal junction (GOJ) cancers. The importance of postoperative component of this regimen is uncertain. The aim of this study was to compare survival and cancer recurrence in patients who have received neoadjuvant and adjuvant chemotherapies according to MAGIC protocol with those patients completing only neoadjuvant chemotherapy. Methods. 66 patients with gastric and GOJ adenocarcinomas treated with neoadjuvant and adjuvant chemotherapies according to the MAGIC protocol were studied. All patients underwent potentially curative surgical resection. The histological, demographic, and survival data were collected for all patients. Results. The median number of neoadjuvant chemotherapy cycles received was 2 (range 1–3). Thirty-one (47%) patients underwent adjuvant chemotherapy with a median of 2 cycles (range 1–3). Patients who have completed both cycles of chemotherapy had significantly improved survival (). Patients with involved lymph nodes and positive longitudinal resection margins had increased incidence of recurrence () and poor five-year survival (). Conclusions. Patients who received both neoadjuvant and adjuvant chemotherapies for gastric and gastro-oesophageal junction tumours have improved outcomes compared to patients who only received neoadjuvant chemotherapy.

Accuracy of Diagnostic Biopsy for Cutaneous Melanoma: Implications for Surgical Oncologists Wed, 11 Sep 2013 11:31:09 +0000 http://www.hindawi.com/journals/ijso/2013/196493/ Background and Objectives. While excisional biopsy is recommended to diagnose cutaneous melanoma, various biopsy techniques are used in practice. We undertook this study to identify how frequently final tumor stage and treatment recommendations changed from diagnostic biopsy to final histopathology after wide local excision (WLE). Methods. We compared the histopathology of the dermatopathologist-reviewed diagnostic biopsy and final WLE in 332 cutaneous melanoma patients. Results. Tumor sites were extremity (51%), trunk (33%), and head/neck (16%). Initial biopsy types were excisional (56%), punch (21%), shave (18%), and incisional (5%). Most diagnostic biopsies were margin positive regardless of technique, and 36% of patients had residual melanoma on WLE. T-stage changed in 8% of patients, of whom 59% were diagnosed by punch biopsy, 15% by incisional biopsy, 15% by shave biopsy, and 11% by excisional biopsy (). Treatment recommendations changed in 6%: 2% after excisional biopsy, 5% after shave biopsy, 18% after punch biopsy, and 18% after incisional biopsy (). Conclusions. Although most biopsy margins were positive, T-stage and treatment changed for only a minority of melanoma patients. Our data provide valuable information to inform patient discussion regarding the likelihood of a change in prognosis and the need for secondary procedures after WLE. These data support the superiority of dermatopathologist-reviewed excisional biopsy when feasible. Tina J. Hieken, Roberto Hernández-Irizarry, Julia M. Boll, and Jamie E.

Preoperative Localization and Surgical Margins in Conservative Breast Surgery Mon, 05 Aug 2013 08:58:21 +0000 http://www.hindawi.com/journals/ijso/2013/793819/ Breast-conserving surgery (BCS) is the treatment of choice for early breast cancer. The adequacy of surgical margins (SM) is a crucial issue for adjusting the volume of excision and for avoiding local recurrences, although the precise definition of an adequate margins width remains controversial. Moreover, other factors such as the biological behaviour of the tumor and subsequent proper systemic therapies may influence the local recurrence rate (LRR). However, a successful BCS requires preoperative localization techniques or margin assessment techniques. Carbon marking, wire-guided, biopsy clips, radio-guided, ultrasound-guided, frozen section analysis, imprint cytology, and cavity shave margins are commonly used, but from the literature review, no single technique proved to be better among the various ones. Thus, an association of two or more methods could result in a decrease in rates of involved margins. Each institute should adopt its most congenial techniques, based on the senologic equipe experience, skills, and technologies. F. Corsi, L. Sorrentino, D. Bossi, A. Sartani, and D.

Quality of Life Study following Cytoreductive Surgery and Intraperitoneal Chemotherapy for Pseudomyxoma Peritonei including Redo Procedures Sun, 28 Jul 2013 12:05:23 +0000 http://www.hindawi.com/journals/ijso/2013/461041/ Background. Our aim was to evaluate the quality of life following cytoreductive surgery and intraperitoneal chemotherapy for pseudomyxoma peritonei. We also conducted an analysis of all patients who underwent CRS and HIPEC for pseudomyxoma peritonei from 1997 to 2012. Methods. We contacted 87 patients using the FACT C (version 4) quality of life questionnaire, and FACIT-TS-G (version 1) was also used. Results. A total of 63 patients (response rate 72%) were available for quality of life interview and analysis. The median time from surgery to questionnaire evaluation was 31 months (range 6–161 months). 62% were females with an average age of 54 years. 22% of the patients had over one cytoreductive surgical procedure. We analysed our patients postoperatively based on physical, functional, social, and emotional well being who reported favourable outcomes in all sections. Patients who had a single procedure had a significantly higher score () in the additional concerns section of the questionnaire. The patients who had a single procedure had better gastrointestinal digestion in terms of bowel control, appetite, and food digestion and also body appearance scoring. Conclusions. 79% of the patients stated that they would undergo further cytoreductive surgery and that redo procedures do not result in a significantly worse quality of life.

Genetic Heterogeneity of Breast Cancer Metastasis May Be Related to miR-21 Regulation of TIMP-3 in Translation Wed, 10 Jul 2013 09:03:02 +0000 http://www.hindawi.com/journals/ijso/2013/875078/ Purpose. MicroRNAs are noncoding RNA molecules that posttranscriptionally regulated expression of target gene and implicate the progress of cancer proliferation, differentiation, and apoptosis. The aim of this study is to determine whether microRNA-21 (miR-21), a specific microRNA implicated in multiple aspects of carcinogenesis, promoted breast cancer metastasis by regulating the tissue inhibitor of metalloproteinase 3 (TIMP-3) gene. Methods. miR-21 of serum and tissue from 40 patients (30 patients with breast cancer) were detected by real-time quantitative reverse transcriptase polymerase chain reaction (RT-qPCR). TIMP-3 of tissue from the patient was tested by real-time RT-qPCR. Protein expression of TIMP-3 was evaluated by western blotting. Correlation analysis was performed between miR-21 and TIMP-3. Results. Of the 40 samples from tissue and serum analyzed, the miR-21 expression was significantly higher in high invasion metastasis group (HIMG) that in low invasion metastasis group (LIMG); the latter was higher than that in normal group (NG). Additionally, the TIMP-3 expression was significantly lower in HIMG than in LIMG; the latter was lower than that in NG. There was significantly inverse correlation between miR-21 and TIMP-3 extracted from tissue. Conclusion. Our data suggest that miR-21 could promote metastasis in breast cancer via the regulation of TIMP3 translation, and there was consistency between miR-21 of serum and miR-21 in tissue.

Staging Laparoscopy in Carcinoma of Stomach: A Comparison with CECT Staging Thu, 02 May 2013 11:37:41 +0000 http://www.hindawi.com/journals/ijso/2013/674965/ Background. aim of this study was to compare the role of diagnostic laparoscopy and contrast enhanced computed tomography (CECT) of abdomen in the staging of stomach carcinoma. Methods. This was a prospective study conducted in a tertiary care hospital over a period of two years and included 50 patients of endoscopy and biopsy proven stomach carcinoma that were found to be operable on CECT. Diagnostic laparoscopy was performed in all patients before proceeding to a formal laparotomy. Results. Metastasis was detected at diagnostic laparoscopy in 14 (28%) patients. CECT correctly identified the T stage in 22 (61%) patients. Overall accuracy of CECT for T staging was 74% with a a sensitivity of 65% and a specificity of 79%. Laparoscopy correctly identified the T stage in 26 (72%) patients. Overall accuracy of laparoscopy for T staging was 81% with a sensitivity of 76% and specificity of 86%. the most common N stage on CECT was N0 (50%). CECT correctly identified the N stage in 26 (72%) patients. Overall accuracy of CECT for N staging was 86% with a sensitivity of 50% and a specificity of 90%. the most common N stage on laparoscopy was N0 and N2 (42% each). Laparoscopy correctly identified the N stage in 27 (75%) patients. Overall accuracy of Laparoscopy for N staging was 88% with a sensitivity of 53% and specificity of 91%. Conclusion. Laparoscopy is a valuable technique in staging of stomach carcinoma and has an important role in the detection of intra-abdominal metastasis missed by CECT.

The Role of Para-Aortic Lymphadenectomy in the Surgical Staging of Women with Intermediate and High-Risk Endometrial Adenocarcinomas Wed, 27 Feb 2013 16:22:06 +0000 http://www.hindawi.com/journals/ijso/2013/858916/ Objectives. To characterize clinical outcomes in patients with intermediate or high-risk endometrial carcinoma who underwent surgical staging with or without para-aortic lymphadenectomy. Methods. This is a retrospective cohort study of patients with intermediate or high-risk endometrial adenocarcinoma who underwent surgical staging with (PPALN group) or without (PLN) para-aortic lymphadenectomy. Data were collected, Kaplan-Meier curves were generated, and univariate and multivariate analyses performed to compare differences in adjuvant therapy, disease recurrence, disease-free survival (DFS), and overall survival (OS). Results. 118 patients were included in the PPALN group and 139 in the PLN group. Patients in the PPALN group were more likely to receive adjuvant vaginal brachytherapy (25.4% versus 11.5%, , ) and less likely to receive adjuvant multimodal combination therapy (17.81% versus 28.8%, , ). DFS was improved in the PLN group as compared to PPALN (80% versus 62%, ). OS was equivalent (). Patients in the PPALN group who had less than 10 para-aortic nodes removed were twice as likely to recur than patients who had 10 or more para-aortic nodes or patients in the PLN group (HR 2.08, CI 1.20–3.60, ). Conclusions. Patients in the PLN group were more likely to receive multimodal adjuvant therapy and had better DFS than the PPALN group. Pelvic lymphadenectomy followed by adjuvant radiation and chemotherapy may represent an effective treatment option for patients with intermediate or high-risk disease. If systematic para-aortic lymphadenectomy is performed and less than 10 para-aortic lymph nodes are obtained, multimodality adjuvant therapy should be considered to improve DFS.

Strategies to Evaluate Synchronous Carcinomas of the Colon and Rectum in Patients That Present for Emergent Surgery Wed, 06 Feb 2013 10:28:53 +0000 http://www.hindawi.com/journals/ijso/2013/309439/ It is not always possible to evaluate patients that present acutely with carcinoma of the colon and rectum for synchronous lesions. Patients that require emergent surgery necessitate urgent and efficient operation. Patients with lower gastrointestinal bleeding, perforation, or obstruction represent a challenging subset of patients with colorectal cancer. An organized approach to these patients in the effort not to overlook a synchronous carcinoma is important. The present paper provides an evidenced-based approach to this special situation.

Value of MR and CT Imaging for Assessment of Internal Carotid Artery Encasement in Head and Neck Squamous Cell Carcinoma Tue, 29 Jan 2013 10:33:25 +0000 http://www.hindawi.com/journals/ijso/2013/968758/ Objective. This study was conducted to assess the value of CT and MR imaging in the preoperative evaluation of ICA encasement. Methods. Based upon three patient groups this study was performed. Retrospective analysis of 260 neck dissection reports from 2001 to 2010 was performed to determine unexpected peroperative-diagnosed encasement. Two experienced head and neck radiologists reviewed 12 scans for encasement. Results. In four out of 260 (1.5%) patients undergoing neck dissection, preoperative imaging was false negative as there was peroperative encasement of the ICA. Of 380 patients undergoing preoperative imaging, the radiologist reported encasement of the ICA in 25 cases. In 342 cases no encasement was described, 125 of these underwent neck dissection, and 2 had encasement peroperatively. The interobserver variation kappa varied from 0.273 to 1 for the different characteristics studied. Conclusion. These retrospectively studied cohorts demonstrate that preoperative assessment of encasement of the ICA using MRI and/or CT was of value in evaluation of ICA encasement and therefore contributively in selecting operable patients (without ICA encasement), since in only 1.5% encasement was missed. However, observer variation affects the reliability of this feature. W. L. Lodder, C. A. H. Lange, H. J. Teertstra, F. A. Pameijer, M. W. M. van den Brekel, and A. J. M. Balm Copyright © 2013 W. L.
