[Four cases of operations for malignant disease in elderly patients]

The management of elderly patients with malignant disease is determined by their condition, complications, and living environment. Sometimes it is difficult to judge surgical indications for elderly patients. We report 4 cases of patients, 80 years or older, who underwent an operation for malignancy. In the first case we performed a bile duct excision for bile duct cancer, and in the second case we performed distal pancreatectomy for pancreatic cancer. Both operations were non-curative, and the patients were alive and maintained quality of life for 12 months after the operation. In the third non-curative operation, we performed total gastrectomy for remnant gastric cancer. The patient died of cancer 4 months after the surgery. In the fourth case we performed pancreaticoduodenectomy for bile duct cancer; it was a curative operation. The patient was in very good condition 4 months post-operation, but died suddenly due to acute myocardial infarction. In operations treating malignancy in elderly patients, it is important for the patients and their families to fully understand the significance of the operations.
