High CD8/CD33 ratio in peritoneal metastatic lesions is associated with favorable prognosis in gastric cancer.

Background: Tumor-infiltrating lymphocytes (TILs) and other immune cells have been reported as a prognostic factor in several tumors, including gastric cancer, and they play an important role in antitumor effect at the primary site. There were few reports on the immune status in peritoneal metastatic lesions for gastric cancer.

Aims: The aims of this study were to assess the prognostic significance of TILs (CD4, CD8, CD19, regulatory T cells [Tregs]), and myeloid-derived suppressor cells (MDSCs) in peritoneal metastatic lesions.

[A Case of Simultaneous Laparoscopic Resection of Sigmoid Colon Cancer and Liver Metastases after Chemotherapy with Modified FOLFOX6 plus Panitumumab].

A 70s-year-old man was referred to our hospital because of sigmoid colon cancer. Computed tomography (CT) revealed a large mass in the right lobe of the liver and small masses in Couinaud segments Ⅳ and Ⅵ. We started systemic chemotherapy with mFOLFOX6 and panitumumab.

[A Case of Ascending Colon Cancer with Extra Iliac Lymph Node Metastases].

We report a case of ascending colon cancer with right extra iliac lymph node metastases. A 60s-year-old woman underwent right hemicolectomy with lymph node dissection in July 2011. Pathological diagnosis was T4 (SE), N1 (2/42), M0, stage ⅢA.
