Endometrial Hyperplasia: Current Insights into Epidemiology, Risk Factors, and Clinical Management

Area of Science:

• Gynecology
• Oncology
• Reproductive Endocrinology

Background:

• Endometrial hyperplasia (EH) represents a spectrum of endometrial proliferative changes, with some lesions posing a significant risk for endometrial cancer.
• Recognizing EH as a precursor to endometrial cancer underscores the critical need for accurate risk stratification and early detection.

Purpose of the Study:

• To synthesize current data on the epidemiology, risk factors, diagnostic modalities, and therapeutic strategies for endometrial hyperplasia.
• To highlight the clinical relevance of molecular insights and personalized medicine in managing EH and preventing endometrial cancer.

Main Methods:

• Comprehensive literature review of recent studies on endometrial hyperplasia.
• Analysis of epidemiological data, molecular markers, histological findings, and imaging techniques.
• Synthesis of current therapeutic approaches, including medical and surgical options.

Main Results:

• Key risk factors for EH include obesity, polycystic ovarian syndrome (PCOS), metabolic dysfunction, and unopposed estrogen exposure.
• Diagnosis relies on a combination of clinical presentation (e.g., irregular uterine bleeding), histological analysis, molecular markers, and imaging.
• Treatment strategies vary based on lesion complexity and patient factors (e.g., fertility preservation), encompassing progestin therapy and surgical interventions.

Conclusions:

• A thorough understanding of EH's multifaceted nature is essential for optimizing patient outcomes and mitigating endometrial cancer development.
• Personalized treatment approaches, informed by molecular profiling and individual risk assessment, hold promise for improving EH management.
• Continued research into molecular insights is crucial for advancing the translational potential in EH therapy and cancer prevention.
