Multiple regional metastases due to colon cancer usually show poor prognosis. Various treatments such as chemotherapy and radiation therapy are not sufficient, and the outcome is generally poor in many cases. We report here on a patient with multiple regional metastases who was successfully treated with several therapies and remains still alive. A 69-year-old man presented with fever and epigastralgia. A colonoscopy revealed primary sigmoid colon cancer. A computed tomography showed multiple hepatic metastases, and metastases to supraclavicular, mediastinal and para-aortic regional lymph nodes. The bone metastases were detected by scintigram. He was treated with combination chemotherapy of 5-FU via hepatic artery and CPT-11 by systemic administration. The primary tumor had completely disappeared (complete response), and metastases to liver and lymph nodes showed a remarkable shrinkage (partial response) after the chemotherapy. In contrast, bone metastases showed progressive growth (progressive disease). Radiation therapy and bisphosphonate infusion for bone metastases were achieved, and the treatments have controlled the growth of the metastases. Primary tumors and metastases are still controlled well for 3 years after the initial chemotherapy.
