DNA aneuploidy in invasive carcinoma of the uterine cervix.

ABSTRACT

Forty cases of squamous cell carcinoma and twenty cases of adenocarcinoma of the cervix were subjected to DNA ploidy analysis to find out the frequency of aneuploid DNA pattern in different types of invasive carcinoma of the uterine cervix and their possible correlation with the clinical stage and age of the patients. From the DNA analysis an increasing trend of DNA aneuploidy was observed from well differentiated (63.6%) to moderately differentiated (70.8%) to poorly differentiated squamous cell carcinoma (83.3%). However, 85% adenocarcinomas of endocervix showed aneuploid DNA pattern. It indicates that aneuploidy increases with tumour dedifferentiation and further confirms the importance of DNA ploidy as a high risk indicator.
