A Case of Long-Term Survival in a Patient with Advanced Gastric Cancer with Para-Aortic Lymph Node Metastasis Who Responded to Combined Modality Therapy

A 59-year-old woman was diagnosed with advanced gastric cancer with para-aortic and Virchow's lymph node metastases (L, Less, type 2, tub1, cT3N2H0P0M1[LYM: #16, Virchow's]). Four courses of S-1(80mg/m / 2, days 1-21)and CDDP(60mg/ m2, day 8)were administered. After the chemotherapy, CT showed that the primary tumor and para-aortic and Virchow's lymph nodes had reduced in size. The clinical stage was ycT3N1H0P0M0, stage III A. The patient underwent distalgastrectomy, D2 dissection, and sampling of the para-aortic lymph nodes(#16b1lat, #16a2int). The pathological diagnosis was L, less, type 1, por1/2, pT2N2H0P0M0CY0, pStage III B. The patient was treated with S-1(80mg/m2, days 1-28)as adjuvant chemotherapy. After 3 courses had been administered(6 months after the resection), swelling of a para-aortic lymph node (#16b1int)was detected using CT. Based on the diagnosis of recurrence in the lymph node, weekly paclitaxel(80mg/m2, days 1, 8, and 15)was administered. After receiving 9 courses of weekly paclitaxel, the swelling of the lymph node disappeared, and the response evaluation was complete response. She discontinued the chemotherapy 5 years and 9 months after the surgery. To date, she has survived more than 6 years after surgery without recurrence. We report a long-surviving patient with advanced gastric cancer with para-aortic lymph node metastasis who received combined modality therapy.
