What this trial studies

This study investigates the effectiveness of combining weight management strategies with megestrol acetate treatment in obese women diagnosed with early-stage endometrioid carcinoma who wish to preserve their fertility. The approach includes intensive lifestyle interventions such as dietary control and exercise, alongside the administration of megestrol acetate, a high-dosage progesterone. The goal is to improve complete response rates and pregnancy outcomes in this patient population, addressing the impact of obesity on treatment efficacy. Participants will undergo thorough eligibility assessments, including imaging studies to confirm the absence of myometrial infiltration or extrauterine involvement.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 45 with a BMI of 24 kg/m² or higher, diagnosed with early endometrioid carcinoma, and seeking fertility preservation.

Not a fit: Patients who do not meet the age, BMI, or cancer diagnosis criteria, or those not interested in fertility preservation, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance treatment outcomes and fertility preservation for obese women with early-stage endometrial cancer.

How similar studies have performed: Previous studies have shown promising results with similar approaches, particularly combining lifestyle interventions with progestin therapy.

Inclusion Criteria:

1. 18 years≤age≤45years
2. BMI (body mass index) ≥24kg/m2
3. Consent informed and signed
4. Pathologically confirmed as endometrial carcinoma Patients with endometrial specimens obtained by endometrial biopsy, diagnostic curettage or hysteroscopy and diagnosed histologically as endometrioid carcinoma, G1. If specimens are from other hospitals, they must be counseled or reconfirmed by the Department of Pathology of the Obstetrics and Gynecology Hospital of Fudan University.
5. Imaging Assessment Enhanced MRI of the pelvis and enhanced CT of the upper abdomen must be performed in 2 weeks prior to starting treatment to assess the lesions confined to the endometrial layer without clear myometrial infiltration or extrauterine involvement.
6. Have a strong desire to reproduce and ask for fertility preservation or those who insist on keeping the uterus despite no reproductive requirements.
7. Have good compliance and follow-up conditions, and patients are willing to follow up in Obstetrics and Gynecology Hospital of Fudan University in time.

Exclusion Criteria:

1. Patients with non-endometrioid endometrial carcinoma, endometrioid endometrial carcinoma G2/G3 or other malignant tumors of the reproductive system; imaging suggests myometrial invasion, cervical involvement or extra-uterine involvement.
2. Combined with severe medical disease or liver or kidney dysfunction: alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels elevate to 3 times or more of the upper limit of normal, kidney dysfunction (creatinine clearance \<30 mL/min)
3. Patients with other types of endometrial cancer or other malignant tumors of the reproductive system; patients with breast cancer or other hormone-dependent tumors that cannot be used with progesterone.
4. Those who have received high doses of high potency progestin or oral contraceptives within the last 3 months (or those on maintenance medication).
5. Those who require hysterectomy or other methods other than conservative treatment.
6. Known or suspected pregnancy.
7. Those who has contraindications to use progestin.
