A Case of Advanced Rectal Cancer with the Metastatic Abdominal Aortic Bifurcation Lymph Node Performed by Laparoscopic Surgery after Chemotherapy

: A 63-year-old underwent examination for constipation and was found to have an unresectable advanced rectal cancer. Metastatic abdominal aortic bifurcation lymph node and lung metastasis were suspected upon CT(cT3N3M1a[PUL1], cStage Ⅳa), and chemotherapy was administered(CapeOX plus Bmab). After 4 courses of chemotherapy, the size of the primary tumor and the lymph nodes decreased(PR). We performed laparoscopic rectum resection and abdominal aortic bifurcation lymph node. The pathological diagnosis indicated partial response(residual cancer cells)(Grade 1a). After 4 courses of chemotherapy(CapeOX), we performed pulmonary partial resection for metastatic lung cancer. This case suggests that laparoscopic resection of rectum after chemotherapy with CapeOX plus Bmab for locally advanced rectal cancer is a potential- ly effective procedure.
