Abstract:
ObjectiveTo study the relationship between DNA aneuploidy and proliferative activity and the clinical and pathologic features.MethodsDNA ploidy and cell cycle analysis were analyzed in 119 colorectal fresh cancer apecimens using flow Cytometry and prospectively compared with the CEA in serum,tumor size,tumor morphology,lymph node metastases,Dukes' Classfication,histologic type and grade in colorectal cancer.ResultsThere was no relation between serum CEA and DNA aneuploidy and proliferative activity. Aneuploidy was detected at 56.5% in ulcerating carcinoma, which was significantly higher than 14.7% in bulge carcinoma (P<0.01). Aneuploidy was detected at 64.7% in middle and lower grade carcinoma, which was significantly higher than 36.5% of high grade carcinoma (P<0.01). No significant differences in aneuploidy were observed with respect to tumor size, lymph node metastases, Dukes' classfication,tumor histologic type.ConclusionsDNA aneuploidy of cancer cell can express the degree of malignancy of colorectal cancer. But proliferative activity does not relate to all the clinical and pathologic features. CEA in serum does not relate to DNA aneuploidy and proliferative activity.
