Abstract:
The patient was a 59-year-old man with type 2 advanced gastric cancer in the antrum. Abdominal computed tomography revealed the primary tumor with regional lymph node metastasis. Distal gastrectomy and D2 lymph node dissection were performed. Histopathological findings indicated gastric small cell carcinoma. Lymph node metastasis was observed microscopically in the #6 lymph nodes. Peritoneal lavage cytology was positive. The pathologic stage of the disease was pT2(MP), med, INF b, ly2, v2, pPM0, pDM0, pN2(6/33: #5, #6), M1, P0, CY1, H0, stage Ⅳ, R1(cy+). After surgery, he received chemotherapy with capecitabine plus oxaliplatin. However, after 1 course of therapy the disease had progressed, and the patient was diagnosed with peritoneal metastasis. Chemotherapy of CDDP plus CPT-11 was initiated, and after 5 courses the patient died.
