Abstract

In a recent one decade, we experienced 461 cases of advanced colorectal cancer, 22 cases (4.5%) of which had small colorectal cancer (SCR) less than 20min in size. A clinicopathological study was made to compare SCR and ordinary colorectal cancers (OCR) over 21mm in size. There were no significant differences in the male-to-female ratio and location of the lesions between both groups. The mean age was young and the invasion depth of mp was common in SCRs compared to OCRs. Rates of vascular invasion and lymph nodes metastases were significantly lower in SCRs. Curative resection rate was higher in SCRs and the prognosis was significantly better in SCRs than OCRs.<br> Another analysis of SCRs was conducted. As for the macroscopic type, 10 lesions were elevated type and 12 lesions were depressed type. As for the growth form, five lesions were PG type and 17 lesions were NPG type. In most of the invasive lesions, elevated type and PG type were inner circlar propria muscle. In most of the invasive lesions, depressed type and NPG type were deeper than outer longitudinal propria muscle. Lymphnode metastasis was found in 3 cases in which macroscopic type and growth form were all depressed type and NPG type. Recurrence occurred in two of those three cases.<br> We conclude that depressed type and NPG type SCRs have a malignant potential. But as a whole, the prognosis of SCRs was better than OCRs. It is important to find out these small colorectal cancers (SCRs) .
