Cytochemical and immunologic of women treated for squamous cell carcinoma of the cervix

A total of 126 individuals were tested for circulating T lymphocyte levels: 10 patients with stage I-III squamous cell carcinoma of the cervix before treatment; 65 women previously treated with radiation for stage I and II squamous cell carcinoma of the cervix; and 51 healthy age-matched controls. Percentages of aneuploid cells and DNA content in vaginal or cervical smears were determined in 94 patients. All patients with squamous cell carcinoma of the cervix had lower ratios and levels of circulating T lymphocytes than healthy controls. Cytologic and cytochemical DNA studies of vaginal and cervical smears revealed that these individuals had high percentages of aneuploid cells in cervical smears as well as high DNA values. Patients with no evidence of dysplasia had increased circulating T lymphocyte levels compared to pretreatment values, a lower number of aneuploid cells, and mean DNA values close to diploid cells. Based on cytologic and quantitative DNA studies of vaginal and cervical smears, postirradiation dysplasia was diagnosed in 17 of 65 women previously treated by radiation for squamous cell carcinoma of the cervix. No difference in the levels of circulating T lymphocytes between women with postirradiation dysplasia and women without this mucosal disorder and no evidence of cancer was found.
