Correlation between Skip N2 Metastases and SUV_max, Long Diameter of Tumor, and Ki67 Expression in Patients with Non-Small-Cell Lung Cancer

Figure 2

The fusion image (a) and MIP image (b) of patients with pulmonary adenocarcinoma and squamous carcinoma. 1a and 1b: a 66-year-old male patient presented with squamous carcinoma in the inferior lobe of the left lung combined with hilar lymph node metastasis. The SUV_max was about 15.1 and Ki67 was about 70, which was presented as non-SN2. 2a and 2b: a 55-year-old male patient showed squamous carcinoma in the middle lobe of the right lung combined with paratracheal lymph nodes. No lymph node metastasis was observed in the right hilum of the lung. The SUV_max was about 10.8, and Ki67 was about 60, which was presented as SN2. 3a and 3b: a 67-year-old male patient presented to our hospital due to adenocarcinoma in the superior lobe of the right lung combined with right hilar lymph node metastasis. The long diameter of tumor was about 24.0 mm, and Ki67 was about 30, which was presented as non-SN2. 4a and 4b: a 64-year-old female patient showed adenocarcinoma in the inferior lobe of the right lung combined with lymph node metastasis beneath the eminence. There were no lymph node metastases in the right hilum of the lung. The long diameter of the tumor was about 47.0 mm, and Ki67 was about 70, which was presented as SN2.
