[Ovarian tumors and pregnancy]

Area of Science:

• Obstetrics and Gynecology
• Reproductive Medicine
• Gynecologic Oncology

Context:

• Ovarian tumors during pregnancy are uncommon, typically discovered incidentally.
• Malignant ovarian tumors occur in 1:10,000 to 1:40,000 pregnancies.
• Histologic subtypes and prognosis are similar to non-pregnant cases, with a trend towards borderline or low-grade lesions.

Purpose:

• To outline the diagnostic and therapeutic strategies for ovarian tumors identified during pregnancy.
• To emphasize the importance of gestational age and tumor stage in treatment decisions.

Summary:

• Management varies by trimester: conservative surgery for Stage IA, radical surgery +/- adjuvant therapy in the first trimester.
• In the third trimester, Cesarean delivery can precede radical surgery with multidisciplinary collaboration.
• Second-trimester management requires careful maternal risk-benefit assessment.

Impact:

• Informs clinical practice for managing pregnant patients with ovarian neoplasms.
• Highlights the need for integrated gynecologic and pediatric care for optimal outcomes.
• Contributes to understanding the unique challenges of ovarian tumor treatment during gestation.
