title: Factors influencing tumor cell kinetics in cervical cancer.
abstract: Fresh tumor tissues instead of paraffin-embedded sections were used to study the clinical significance of the tumor cell kinetics in cervical carcinomas by flow cytometry. We analyzed specimens from 153 women with cervical cancer, and DNA aneuploidy was found in 61 cases (39.9%). The mean age of patients with aneuploid tumors was significantly higher than the age of patients with diploid tumors (P < 0.001). The mean proliferation index for aneuploid tumors was significantly higher than those for diploid tumors. There was a significant correlation between the proliferation index and age. However, tumor cell kinetics is not related to the status of human papillomavirus, herpes simplex virsuses I and II, lymph nodes, histology or tumor size. The mean age and S-phase fraction for stage-II tumors were significantly higher than those for stage-I tumors (P < 0.01). The tumors of menopausal patients exhibited a relatively higher rate of lymph node metastasis, and significantly higher aneuploidy rate and proliferation index than tumors of premenopausal patients. In summary, age and, what is more important, menopausal status may significantly influence DNA ploidy and cell kinetics of tumors, and subsequently influence clinical stage and lymph node metastasis. However, tumor cell kinetics is of limited value in the prediction of lymph node metastasis and prognosis.
