[Peritoneal disseminated recurrence after total gastrectomy for perforated gastric malignant lymphoma--a case report]

We reported a case of peritoneal disseminated recurrence after total gastrectomy for perforated gastric malignant lymphoma. A 73-year-old man underwent total gastrectomy for perforated gastric diffuse large B cell lymphoma on day 5 of RCHOP (rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisolone) chemotherapy. He has rejected chemotherapy and received no additional treatment after gastrectomy. Computer tomography 13 months after surgery revealed peritoneal dissemination and abdominal lymph node metastasis. R-CHOP chemotherapy was performed, and after 4 courses of chemotherapy, peritoneal dissemination and metastatic abdominal lymph nodes disappeared. Chemotherapy was discontinued for a time, however, the tumors relapsed 2 months after stopping chemotherapy. He underwent chemotherapy with etoposide, but died of tumor progression 21 months after gastrectomy.
