摘要
本文对30例大肠癌细胞核DNA含量进行了检测,其中管状腺癌15例(Ⅰ、Ⅱ、Ⅲ级各5例),乳头状腺癌、粘液腺癌、印戒细胞癌各5例,同时,选正常大肠粘膜5例做对照。测定结果:正常大肠粘膜DNA含量为13.54±1.76Au,管状腺癌Ⅰ级22.62±3.36Au,Ⅱ级26.41±0.70Au,Ⅲ级31.12±2.32Au,乳头状腺癌、粘膜腺癌、印戒细胞癌分别为:27.22±1.41Au、27.94±2.41Au、20.4±3.40Au。各组癌细胞DNA含量与正常粘膜:管状腺癌Ⅰ级、印戒细胞癌与管状腺癌Ⅲ级、乳头状腺癌、粘液腺癌相差非常显著(P<0.01),管状腺癌Ⅲ级与Ⅱ级、乳头状腺癌、粘液腺癌相差显著(P<0.05)。随访结果表明:DNA含量越高,分布范围宽、高峰后移预后差。检验结果表明:大肠癌DNA含量可为大肠癌的分类和估价预后提供客观参考指标。
The DNA content was quantitively determined in 30 specimens of colorectal carcinoma including 15 cases of tubular adenocarcinoma (TAC.5 cases each of grade Ⅰ,Ⅱ and Ⅲ respectively) ,5 cases of papillary adenocarcinoma (PAO.5 cases of mucoid adenocarcinoma (MAC) and 5 cases of signet-ring cell carcinoma (SCO),and 5 specimens of norma! colomic nucosa with mi-crospectro-photometry.The average DNA contents of different tissues were as follows:Normal colonic mucosa:13.54The difference of DNA contents of various types of carcinoma with normal mucosa,and that of TAC-Ⅰ and SCC with TAC-Ⅲ,PAC and MAC was statistically very significant (P<0.01),and that of TAC-Ⅲ with TAC-Ⅱ,PAC and MAC was significant (P<0.05).Followup study of these cases revealed that the higher the DNA content,the wider the distribution range .and more leftward shift of the peak value.the poorer the prognosis.Laboratory study revealed that the DNA content of colorectal carcinoma can be used as an objective reference for prognosis and TAC grading.
