Uterine adenosarcomas: A dual-institution experience

Area of Science:

• Gynecologic Oncology
• Pathology
• Surgical Oncology

Background:

• Uterine adenosarcomas are rare neoplasms with limited published literature on optimal treatment and follow-up.
• Their rarity poses challenges for establishing evidence-based management guidelines.

Purpose of the Study:

• To retrospectively analyze treatment and follow-up data for uterine adenosarcomas.
• To identify potential factors influencing recurrence and survival.
• To inform the development of refined treatment strategies for this rare tumor type.

Main Methods:

• Retrospective review of medical records from two major Turkish women's health hospitals.
• Identification of 15 patients diagnosed with uterine adenosarcoma.
• Analysis of patient demographics, tumor characteristics, treatment received, recurrence patterns, and survival outcomes.

Main Results:

• Median follow-up was 86.43 months.
• Seven out of 15 patients experienced recurrence, with 4 of these having Stage IA disease.
• Median Disease-Free Survival (DFS) was 41.47 months and Median Overall Survival (OS) was 57.21 months.

Conclusions:

• Polypoid uterine adenosarcomas confined to the uterus with superficial myometrial invasion may be managed without comprehensive surgical staging.
• Publication of data from rare cases is crucial for future meta-analyses and improved treatment strategies.
