大腸癌他臓器浸潤症例の検討

The clinicopathologic features of 39 cases of colorectal cancer with invasion to the adjacent organs (si,ai) were studied. Twenty seven were cases with combined resection of involved organs. Twenty two and 17 cases were located in colon and rectum, respectively. The D region was mostly involved, followed by, the C and T region. Five cases had invasion to the gastrointestinal tract, 2 cases had invasion to the liver, gall bladder or pancreas. Twenty one cases had urogenital organ invasion and 11 cases had invasion to sacrum and other organs. The survival rate of cases with combined resection of the involved organs was significantly high compared with non-resection. Also, the survival rate of curative resection was significantly high compared with non-curative resection. Aggressive resection of involved organs seems to be important for good prognosis.
