[A Case of StageIV Gastric Cancer with Development of Trousseau's Syndrome during Neoadjuvant Chemotherapy].

In October 2012, a man in his 60s was hospitalized for the examination of ascites, and was diagnosed with gastric cancer and carcinomatous peritonitis. S-1+cisplatin (CDDP) therapy was administered as neoadjuvant chemotherapy; however, during therapy, he developed cerebral infarction. We suspected that the cerebral infarction was caused by a coagulation disorder owing to Trousseau's syndrome. After completing 5 courses of chemotherapy, total gastrectomy was performed. Thereafter, the treatment was changed to S-1+docetaxel(DTX), followed by nab-paclitaxel (PTX). Although cerebral infarction did not relapse after the administration of an anticoagulant agent, the patient died of gastric cancer 1 year and 5 months after the operation. Trousseau's syndrome is a coagulation disorder in cancer patients. Cerebral infarctions caused by Trousseau's syndrome have a high tendency to relapse, and the prognosis is poor. This syndrome should be kept in mind when treating cancer patients.

[Radical nephrectomy and caval tumor thrombectomy with cardiopulmonary bypass combined with right anterior minithoracotomy;report of a case].

Renal cell carcinoma is a tumor with a distinct feature that it can invade the renal vein and grow intravascularly extending to the inferior vena cava (IVC). We herein report a case of a 71-year-old female who presented with a neoplasm that involved the right kidney and an intra-IVC tumor thrombus. We performed radical nephrectomy and tumor thrombectomy under cardiopulmonary bypass through a right anterior mini thoracotomy. The patient was discharged on the 13th day after the surgery without any complication, and is currently in good health at 7 months after the operation.
