A Case of Multiple Metastases to the Soft Tisues after Surgery for Metastatic Abdominal Wall Tumors of Gastric Cancer

Abstract

A 62-year-old man underwent distal partial gastrectomy for advanced gastric cancer (sig, por, T4aN1M0, Stage IIIA). The patient was given adjuvant chemotherapy consisting of 6 courses of capecitabine plus oxaliplatin. Nine months after the initial operation, two metastatic abdominal wall tumors were found on the operation scar. The tumors were removed surgically, and the abdominal wall defect was reconstructed with mesh. Nine months after removal of the abdominal tumors, new metastatic tumors appeared in the lower right abdominal wall. Three months later, metastatic tumors appeared in the gluteal muscles and the skin of the whole body. The patient was treated with 2 courses of a weekly paclitaxel regimen. However, each tumor grew, so the chemotherapy was interrupted, and he was changed to palliative therapy. He died of progressive disease 17 months after resection of the abdominal wall tumors. We report a case of abdominal wall metastasis resection of gastric cancer, in which the patient lived without any cancer recurrence for 9 months after operation, but then developed systemic soft tissue metastasis and died. This case highlights the need to think about the treatment plan for abdominal wall metastases of gastric cancer and attempt to predict the clinical course after their resection.
