[A Case of Resection of Para-Aortic Lymph Node Recurrence following Rectal Cancer Surgery].

A 54-year old man diagnosed with rectal cancer underwent laparoscopic high anterior resection with Japanese D3 lymph node dissection. The pathology results were as follows: pT2pN3M0, pStage Ⅲb(Japanese Classification of Colorectal, 8th edition). Adjuvant chemotherapy with CapeOX regimen was administered 8 courses. 1.5 years after the operation, computed tomography(CT)examination revealed a swollen para-aortic lymph node(PALN). Positron emission tomography (PET)-CT revealed PALN with high FDG uptake. We considered that neo-adjuvant chemotherapy and PALN dissection may be possible for PALN, which was isolated metastasis and curative by surgery. After 6 courses of bevacizumab-FOLFIRI therapy was administered, PALN dissection was performed. Pathological examination of the resected specimen showed adenocarcinoma in 4 of the 16 dissected lymph nodes. Histological treatment effect of preoperative therapy was Grade 1b. Postoperatively 6 courses of FOLFIRI were administered. The patient has been followed up for 7 years and 8 months after the first surgery, 5 years and 9 months after the curative resection, with no recurrence showed complete cure. Multidisciplinary treatment with anticancer drug and R0 resection was an effective treatment for isolated PALN recurrence of rectal cancer.
