Fertility after the treatment of gynecologic tumors.
In a young woman with gynecologic cancer, preservation of fertility is possible. Fertility-sparing surgery may be safe in early ovarian cancer of certain histological subtypes such as ovarian tumors of low malignant potential, malignant ovarian germ cell tumors, and ovarian sex cord stromal tumors. For women with invasive epithelial ovarian cancer who have early-stage disease, fertility-sparing surgery may be an option. In some cases, fertility-sparing surgery may be followed by postoperative chemotherapy. The concept of fertility-preserving surgery in early cervical cancer has been adopted by several leading centers worldwide as an option for stage Ia and small Ib disease without the presence of lymphovascular involvement. Nonsurgical options such as hormonal therapy may be considered for women with early-stage, low-grade endometrial cancer. Improvements in cancer cure rates and the development of conservative treatments mean that many young women with early gynecologic cancer can hope to start a new pregnancy after the treatment. Patients are generally advised to wait 2 years after treatment for any malignancy before attempting pregnancy, but the optimal interval between cure and conception must be carefully determined by a multidisciplinary team including oncologist and obstetrician. Gynecologic surgery and hemotherapy can have an impact not only on fertility, but also on the course of a next pregnancy (increased risk of miscarriage and premature delivery, etc.) These risks must be taken into account by the obstetrician. Management of young women diagnosed with gynecologic cancer should be individualized, with the risk of conservative therapy balanced against the disadvantages of more radical treatment. The patient and the family should be extensively counseled. The alternatives to the traditional and standard radical procedures should be discussed, and the limitation of data regarding many conservative treatment options should be explained. The patients should be aware that by accepting fertility-sparing treatment they are assuming a small but undefined risk for recurrence of the disease. They need to know that these conservative therapeutic approaches are yet not considered "standard." Furthermore, patients need to be assessed for the realistic probabilities of achieving conception on the basis on their age, history, and infertility evaluation. Some of them will require assisted reproduction technology (ARTS) to help achieve a pregnancy, especially in vitro fertilization (IVF). They may also consider ovarian tissue, oocyte, or embryo cryopreservation before definitive cancer therapies. And, finally, patients also need to understand the risk of premature delivery and the consequences of prematurity. The care of the young patient with gynecologic malignancy is extremely complex and challenging. It necessarily requires a multidisciplinary approach with the close collaboration of gynecologist-oncologist, reproductive endocrinologist, and perinatologist.
