Study subjects included 2339 cases aged 22 to 64 years with newly diagnosed squamous cell cervical cancer in 10 participating medical centers, and 13,506 hospitalized controls matched on age and place of residence to the cases. After adjustment for age, center, caesarian section, number of live births, number of marriages or other sexual relationships, age at first sexual relationship, and frequency of Pap smears, a small decrease in risk was observed during the first 5 postoperative years. Tubal ligation probably provides an opportunity for secondary prevention of cervical cancer. © 2000 Elsevier Science Inc.Mahidol UniversityMedicineArticleSCOPUS10.1016/S0010-7824(00)00111-6
