Time to Endoscopy in Patients with Colorectal Cancer: Analysis of Wait-Times

Table 1

Summary of patient and cancer characteristics for included subjects. The majority of patients were male. The majority of patients had alarm symptoms at the time of referral to the SPH gastroenterologists. The location of cancer was distal in 60% of patients, with either CRC in the rectum or sigmoid colon on surgical pathology. Most patients had no evidence of local nodal invasion (as determined by pathology) and no evidence of distant metastatic disease (as determined by imaging) at the time of diagnosis.
