Abstract: INTRODUCTION: Vulvovaginal cancer in pregnancy is rare. Limited data complicate decision-making and patient counseling. Our review, coupled with new case data, fills a current gap in the literature and provides practical insights. MATERIAL AND METHODS: Oncological and obstetric data of these pregnancies were examined by a case collection from the International Network on Cancer, Infertility and Pregnancy (INCIP) registry (vulvar n = 10, vaginal n = 5) and a literature review (vulvar n = 46, vaginal n = 37). RESULTS: Although preoperative imaging of inguinofemoral lymph nodes is feasible, only 16.1% of vulvar cancer patients underwent ultrasound or MRI. Treatment was initiated during pregnancy for 69.1% of vulvar cancer and 28.4% of vaginal cancer patients. Surgical lymph node staging of vulvar cancer was postponed until after delivery in 10 cases, although uni- or bilateral lymphadenectomy during pregnancy was not associated with more complications. Delivery outcomes included a live birth rate of 96.4% for vulvar cancer and 50% for vaginal cancer due to the high rate of pregnancy terminations, with most births preterm. The overall 5-year survival rates for vulvar (81.3%) and vaginal (66.4%) cancer during pregnancy are comparable to nonpregnant populations, indicating that pregnancy does not adversely impact maternal prognosis. CONCLUSIONS: This study underscores the feasibility of adapting standard oncological care for pregnant patients, emphasizing multidisciplinary teams to optimize maternal and fetal outcomes.
