[Successful surgical treatments for pulmonary and/or hepatic metastases after surgical resection for colorectal cancer--two case reports].

In colorectal cancer, hepatic and pulmonary metastases are the most common and most important prognostic factors. Surgical resection is the first choice of treatment for hepatic and pulmonary metastases if completely resectable. However, only a few patients survived long term after metastatectomy. We present the two cases, in which surgical resection for pulmonary and/or hepatic metastases from colorectal cancer resulted in long-term survival for more than ten years without recurrence.
