抄録

During the past 16 years, we experienced 689 cases with advanced colorectal cancer lesions, 18 cases (2.6%) of which had small cancer lesions less than 2 cm in diameters. Among these 18 cases, 10 were male and 8 were female with a mean age of 64.3 years. These 18 lesions were investigated macroscopically and histologically. Eight cases were diagnosed as colorectal cancer by positive fecal occult blood, and 16 cases showed normal serum CEA levels. The cancer lesions were found mainly in the left colon or rectum and complicated by adenoma and so on. As for the gross form, 16 lesions were NPG type and the other 2 lesions were PG type. The relationship between the macroscopic type and the depth of invasion were examined. Most of the invasive lesions of the elevated type were propria muscle. Among the depressed types, according to the increase of the depressed lesions (from IIa+IIc type to IIc type), the depth of invasion increased. Lymph node metastasis was found in 4 cases whose cancer lesions were all NPG type. Those macroscopic types were mainly IIa+IIc or IIc, with deep invasion.<BR>These data suggested that even these small lesions should not be ignored or over-looked because of the high malignancy potential there of.
