Contraception Use in Cancer Survivors, Clinical Practice and Patients' Preferences

Current literature suggests that emergency contraception, defined as a therapy aimed at preventing an unwanted pregnancy after unprotected or insufficiently protected intercourse, is used more by cancer survivors than by the general population. This may be related to reduced use of contraception in women after cancer diagnosis and, when it is used, to a choice of less effective methods, even in the absence of contraindications to hormonal options. The purpose of this review is to analyze the use of contraception in these patients, its predictors and the preferred methods, as well as to try to define timing and characteristics of an effective contraception counseling. Factors identified as predictors of contraception usage were younger age, having a partner and better sexual function, having children, past use and having received contraception counseling by a gynecologist, especially in the previous year. Contraception counseling should start before oncological therapies, together with information regarding fertility and sexual health, preferably by the gynecologist of the oncofertility unit, with a specific expertise in dealing with cancer patients. Increased awareness of oncologists and family medicine doctors is fundamental to optimize contraception use and compliance with the prescribed method. Major guidelines regarding oncological care in women of fertile age already recommend contraception counseling, but optimal timing and mode of the consultation(s) options should be further researched, to be better detailed in all relevant documents.
