Doctors are working to learn more about uterine cancer, ways to prevent it, how to best treat it, and how to provide the best care to people diagnosed with this disease. The following areas of research may include new options for patients through clinical trials. Always talk with your doctor about the best diagnostic and treatment options for you.

  • New therapies. The most notable development in the treatment of endometrial cancer, and many other types of cancer, is doctors’ increasing understanding of tumor genomics. This area of science seeks to identify mutations in the tumor’s genes that might “drive” or cause the tumor to grow. Testing can be done on your tumor sample to look for these mutations, and the results will help decide whether your treatment options include a type of treatment called targeted therapy, which may include clinical trials.

    In endometrial cancer, mutations in a pathway called PI3K/AKT/MTOR are commonly found. Patients with recurrent uterine cancer may benefit from using a drug that targets this pathway, such as everolimus (Afinitor). Other drugs that target this pathway are available. A study from 2014 showed that combining everolimus with the chemotherapy letrozole (Femara) slowed the growth of the disease in women with recurrent endometrial cancer. The MTOR inhibitor, temsirolimus (Torisel), is a targeted therapy approved to treat renal cell carcinoma, a type of kidney cancer. Clinical trials are investigating its use to treat recurrent, metastatic, or high-risk uterine cancer. 

    Another type of targeted therapy that has shown some results for patients with endometrial cancer are called angiogenesis inhibitors. For example, bevacizumab (Avastin) targets blood vessel growth that feeds tumors.

    Other research includes immunotherapy, which are treatments designed to boost the body's natural defenses to fight the cancer. There is interest in a specific area of immunotherapy called “checkpoint inhibitors,” such as PD-1 or CTLA4 targeted immunotherapies. Examples of immunotherapies are nivolumab (Opdivo) or ipilimumab (Yervoy). They help activate the immune system and can cause tumors to shrink. Some of these immunotherapies work better in combination with other treatment types. There are ongoing clinical trials examining different drugs and various combinations in uterine cancer. There is early evidence that uterine cancers with mismatch repair defects (see Introduction) are much more sensitive to immunotherapy, and this is being studied.

  • Palliative care. Clinical trials are underway to find better ways of reducing symptoms and side effects of current endometrial cancer treatments to improve patients’ comfort and quality of life.

Patients are strongly encouraged to talk with the doctor about clinical trials when decisions are being made about their treatment options.
