Epithelial ovarian cancer and borderline tumors during pregnancy: a report from the International Network on Cancer, Infertility, and Pregnancy

To describe the oncological and obstetrical outcomes of women diagnosed with borderline ovarian tumors or epithelial ovarian cancer during pregnancy. This is an international retrospective cohort study. Patients were eligible for inclusion if they were diagnosed with borderline tumor or invasive ovarian cancer during pregnancy, with histologic confirmation either before or after delivery, and were registered in the International Network on Cancer, Infertility and Pregnancy database between 1982 and 2019. A total of 129 patients were included, of whom 69 (53%) with borderline and 60 (47%) with invasive cancer. Diagnosis was established in the first, second, and third trimesters in 59 (46%), 48 (37%), and 22 (17%) patients, respectively. In total, 47 (36%) patients did not receive any treatment during pregnancy. The majority of patients (64%) underwent surgery with or without chemotherapy during pregnancy. Birthweight was significantly lower in women who received chemotherapy during pregnancy as compared to those who did not (median birthweight 2528 g vs 3031 g, p = .01) Among patients with borderline tumors, 20 (29%) experienced a relapse of whom 2 subsequently died from the disease. The 5-year survival probability was 98.5% (95% CI 95.6 to 100). Recurrence was associated with incomplete surgical staging (p = .02). Among patients with epithelial ovarian cancer, the relapse rate was 25% and the 5-year survival probability was 83.6% (95% CI 74.3 to 94.1). The oncological outcome was worse for patients with advanced-stage disease (p = .03). In addition, 66% of patients who relapsed after pregnancy did not undergo adequate surgical staging. Treatment of patients with ovarian cancer during pregnancy can result in favorable oncological and obstetrical outcomes. Better oncological outcomes are achieved when treatment adheres to the standard of care in non-pregnant patients, as those who did not undergo surgical staging experienced a higher relapse rate.

Vulvar and vaginal cancer during pregnancy: A pooled analysis of 15 cases from the International Network on Cancer, Infertility and Pregnancy and review of the literature

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.
