Management of a patient diagnosed with ovarian cancer during pregnancy

Abstract

Insufficient diagnosis of ovarian tumors during pregnancy and decreased oncological alertness constitute huge problems that can subsequently have an unfavorable outcome for both the pregnant woman and the fetus. The difficulties of diagnosing and treating ovarian cancer during pregnancy were demonstrated on the following clinical case example. In pregnant patient A. at 19-20 weeks of pregnancy, a lesion was found in the area of the right appendages (100.9 × 55.4 × 93.4 mm, V = 273 cm³), with many tissue partitions and parietal tissue inclusions. The growth of the neoplasm was noted (CA-125 884 U / ml) and the pain syndrome occurred in the patient at 23-24 weeks of pregnancy. Magnetic resonance imaging revealed a solid-cystic neoplasm of the right ovary (cystadenoma?) and surgery was performed in November 2019. Based on the results of histological examination, a high-grade serous ovarian cancer was diagnosed without signs of microsatellite instability MSI-H/dMMR (in the right ovary, in the biopsy of the left fallopian tube). The patient. received two cycles of polychemotherapy (TC scheme). The treatment was tolerated satisfactorily (CA-125 287.3 U / ml). At a gestational age of 34 6/7 weeks (January 2020), a simultaneous operation was performed, including a lower midline laparotomy, a lower uterine segment caesarean section, extirpation of the uterus with appendages, and an omentectomy. A boy was born (weight 2280 g, height 44 cm) with the Apgar score of 7/7 points, with no complications noticed in the postpartum period. Postoperative histological examination showed metastasis of carcinoma in the left ovary with signs of therapeutic pathomorphosis. The treatment was completed in March 2020 after six cycles of polychemotherapy.
