Endometrial Cancer Stage I

SHAPE-ENDO is a single-center, open-label, pilot randomized clinical trial conducted at Hospital Universitari de Bellvitge in Barcelona, Spain. The study will evaluate the feasibility, safety, and acceptability of comparing two treatment strategies in women with atypical endometrial hyperplasia/endometrial intraepithelial neoplasia or low-risk endometrioid endometrial cancer and grade III obesity, defined as BMI ≥40 kg/m². Eligible participants will be randomized in a 1:1 ratio to one of two arms. The control arm will undergo standard immediate surgery according to the institutional clinical protocol. The experimental arm will receive the SHAPE-ENDO multimodal pre-surgical optimization strategy before surgery. The SHAPE-ENDO strategy includes metabolic treatment with semaglutide/Wegovy®, local hormonal therapy with a levonorgestrel-releasing intrauterine device/Mirena® with or without oral medroxyprogesterone acetate/Progevera®, a structured nutritional program, adapted physical exercise, and scheduled oncologic surveillance with clinical evaluation, imaging, and endometrial biopsy with or without hysteroscopy. The experimental strategy will initially last 28 weeks. In participants with clinical, metabolic, or anthropometric benefit, adequate tolerance, and no evidence of tumor progression, the strategy may be extended up to 54 weeks before surgery. The primary objective is to evaluate the feasibility, safety, and acceptability of the randomized trial design. Primary feasibility outcomes include recruitment rate, acceptance of randomization, retention, adherence to the assigned intervention, completion of the SHAPE-ENDO strategy, progression during the optimization period, and the proportion of participants in the experimental arm who reach surgery without tumor progression. Secondary outcomes include perioperative morbidity, histological response in the experimental arm, metabolic and anthropometric changes, quality of life, treatment adherence, safety and tolerability, and exploratory long-term oncologic outcomes including overall survival, recurrence-free survival, and cancer-specific survival.

This study is being done to find out how often endometrial cancer recurs after the standard treatment as well as how often the standard treatment results in a lymphedema.

Endometrial cancer (EC) is the most common gynaecological cancer. Current treatment of EC typically includes removal of the uterus and to determine the extent of the disease (removal of fallopian tubes, ovaries \& if required a lymph node dissection (surgical staging)). While lymph node dissection may be valuable to guide the need for adjuvant treatment (chemo or radiotherapy) after surgery, it has been a topic of controversy for the last 30 years. In some patients it causes morbidity, specifically lymphoedema. This recently has been replaced with sentinel node biopsy (SNB). It requires an injection of a dye into the cervix with specific equipment \& surgical dissection of the lymph node in which the dye first becomes visible. Despite this promising proposition \& similar to a lymph node dissection, the value to patients, cost effectiveness \& potential harms (e.g. lymphedema) of SNB compared to no-node dissection in EC has never been established. Aim: determine the value of SNB for patients, the healthcare system and exclude detriment to patients using a randomised approach 1:1. Stage 1 - 444 patients. Stage 2 additional 316 patients. Primary Outcome Stage 1: Proportion of participants returning to usual daily activities at 12 months from surgery using the EQ-5D which will determine when women in both groups can return to their usual activities. Primary Outcome Stage 2: Treatment non-inferiority as evaluated by disease-free survival status at 4.5 years post-surgery, as measured by the time interval between the date of randomisation and date of first recurrence. Confirmation of recurrent disease will be ascertained through clinical assessment, radiological work-up and/or histological results.

To assess the feasibility of an expedited referral process for the obese endometrial cancer or EIN patient from her gynecologic oncologist to the Brigham Center for Metabolic and Bariatric Surgery (CMBS) in order to undergo concurrent weight loss surgery and hysterectomy within 8 weeks of first appointment with a gynecologic oncologist (or 12 weeks for EIN patients).

This clinical trial evaluates lymph node mapping in newly diagnosed endometrial cancer patients undergoing surgery. The standard technique uses a 2-point methylene blue cervical injection. The study aims to determine if increasing injection points improves mapping success.

This is a prospective, multicenter, randomized phase III trial among women with endometrioid adenocarcinoma with high-intermediate and intermediate risk features to investigate the role of integrated genomic-pathologic classification to determine if participants should receive no adjuvant therapy, vaginal brachytherapy, external beam radiotherapy or chemo-radiation therapy based on molecular features as compared to standard radiation therapy.

The main goal of this clinical trial is to evaluate dostarlimab, an immunotherapy drug, as a potential alternative to surgery for early-stage endometrial cancer with Mismatch Repair deficiency, a genetic cause for 20-30% of cases. The study aims to establish dostarlimab's efficacy and safety in early-stage endometrial cancer, exploring its potential as a non surgical option for those unsuitable or unwilling to undergo major surgery, allowing for fertility preservation or addressing specific health conditions. Participants will have seven dostarlimab sessions over 12 months. The treatment plan involves four cycles every three weeks, followed by a three-week break, and then three cycles every six weeks. This research is a promising step toward a new, less invasive treatment choice for patients with specific genetic traits. It expands the range of care options for endometrial cancer.

The goal of this clinical trial is to evaluate the effect and adverse side effects of membrane-inhibiting formula plus oral progestins as fertility-preserving treatment in patients with early-stage endometrial cancer and endometrial hyperplasia research questions：When taken with oral progestins, does the drug membrane-inhibiting formula shorten the time required for complete endometrial remission? What medical problems do participants have when taking drug membrane-inhibiting formula plus oral progestins? Efficacy, side effects, recurrence, pregnancy, and time to obtain pregnancy in different molecular classifications of POLE-mutated, mismatch repair-deficient(MMRd), p53 wild type(p53wt), and p53-abnormal(p53abn). Participants will: Take drug membrane-inhibiting formula plus oral progestins every day Visit the clinic once every 3 months for checkups, tests, and hysteroscopy Keep a diary of examination results and pathology
