What this trial studies

This observational study investigates the prognostic role of molecular classifications in guiding fertility-sparing treatments for women with early-stage endometrial cancer. It focuses on patients aged 18-45 who have a confirmed diagnosis and desire to preserve their fertility. The study aims to analyze how different molecular subtypes, identified through next-generation sequencing, impact treatment outcomes and response rates. By understanding these classifications, the research seeks to personalize treatment approaches for better patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are women aged 18-45 with early-stage endometrial cancer who wish to preserve their fertility.

Not a fit: Patients with atypical endometrial hyperplasia, non-endometrioid histology, or those with medical contraindications to hormonal therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and personalized fertility-sparing treatment options for women with endometrial cancer.

How similar studies have performed: Previous studies have shown promise in using molecular profiling to guide treatment in endometrial cancer, indicating a potential for success in this approach.

Eligibility criteria

Exclusion Criteria:

1. Patients with atypical endometrial hyperplasia or intraepithelial neoplasia
2. Individuals with tumor samples of insufficient quantity or inadequate quality were not included in the analysis
3. Non-endometrioid histology.
4. Patients with a history of prior uterine malignancy or current synchronous malignancies.
5. Medical contraindications to hormonal therapy
