Brief Summary

Endometrial cancer, the most common gynecologic malignancy in high-income countries, is increasing among reproductive-age women. While hysterectomy prevents pregnancy, hormonal therapies offer fertility-sparing options for select early-stage cases, with \~80% achieving complete response (CR). Molecular classifications (POLEmut, p53abn, MMRd/MSI-H, NSMP) reveal subtype-specific prognostic differences, with NSMP showing higher CR rates and lower recurrence, while p53abn and MMRd/MSI-H fare worse. Recent studies emphasize molecular profiling's potential to guide personalized fertility-sparing treatments. This study explores the prognostic role of these classifications in treatment outcomes.

Outcome Measures

Primary Outcomes (2)

  • Response to fertility sparing treatmetn

    To assess the differences in Complete Response (CR), Partial response/stable disease (PR/SD) and progression disease (PD) rates among molecular subtypes (NSMP, POLEmut, p53abn, MMRd/MSI-H) of endometrial cancer in patients undergoing fertility-sparing treatment.

    12 months

  • Recurrence

    To evaluate the recurrence rates of endometrial cancer among these molecular subtypes following fertility-sparing treatment after a CR

    12 months

Secondary Outcomes (2)

  • Time to CR response

    12 months

  • Obstetric outcomes

Study Population

This is a prospective study enrolling patients with endometrial cancer eligible for fertility-sparing treatment. Data of consecutive patients treated from the 21st of January 2025.

You may qualify if:

  • Patients aged 18-45 years with a hysteroscopic confirmed diagnosis of endometrial cancer (FIGO stage IA without myometrial invasion, grade 1 or grade 2, endometrioid histology).
  • Patients desiring fertility preservation
  • Molecular classification of the tumor using next-generation sequencing (NGS) or Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE).
  • Adequate pre-treatment imaging (MRI or transvaginal ultrasound) confirming no evidence of myometrial invasion or extrauterine spread.

You may not qualify if:

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