A gynecological cancer clinical trial - EN10

Tailoring therapy in post-surgical patients with low risk endometrial cancer
Trial Code
EN10 | NCT05640999
Trial Status
Open to patient enrollment

What is the purpose of this study?

The purpose of this study is to identify people who may not require treatment after surgery or may require less treatment after surgery because their cancer is at such a low risk of coming back based on the specific tumour features found by the laboratory testing and the extent of tumour spread. Receiving no treatment or less treatment can result in no or fewer side effects (fatigue, hair loss, bowel and bladder irritation).

Why is this study important?

This study is being done to answer the following question: Are there types of early-stage endometrial cancer that require less treatment than the usual approach?

We want to find out if receiving no treatment or less treatment is better or worse than the usual approach for your early-stage endometrial cancer. The usual approach is defined as care most people receive for early-stage endometrial cancer.

Who can participate in this study?

This trial is for people 18 years of age or older who have Stage I to III endometrial carcinoma and have had surgery to remove the uterus, fallopian tubes and ovaries.

What are the risks?
  • If you choose to take part in this study, getting no treatment or less treatment after surgery means there is a risk that the cancer may have a greater chance of coming back. Researchers will monitor this closely. You will find details of all side effects in the consent document.
What can I expect?
  • If you decide to take part in this study, the specific features of your tumour found by the laboratory testing and the extent of tumour spread will be reviewed. Based on the results, your doctor might recommend that you join the trial. The specific therapy that is recommended to you will consist of no additional therapy after surgery or less therapy than you would have received as part of your usual treatment.In this study, you will also be asked to complete a few questionnaires at different times, for us to understand your quality of life.
