Testing benefits and side effects of hormone therapy in older breast cancer patients

Breast Cancer

Treatments studied

Part of Cancer, Skin clinical trials.

This study looks at the potential harms and benefits of hormone (endocrine) therapy in people age 70 and older with early-stage, hormone-receptor–positive breast cancer. It may help doctors choose which hormone treatment approach is safest and most helpful for older patients.

NCT02476786Recruiting· Phase 2
Hormone treatment only for older ER-positive breast cancer

This Phase 2 study tests whether using hormone (endocrine) treatment alone can control breast cancer in people age 70 and older. It targets breast cancers that are estrogen-receptor positive and HER2 negative, aiming to avoid chemotherapy-like treatments in suitable patients.

Hormone therapy alone for older women with early breast cancer

This trial tests whether a pill (a CDK4/6 inhibitor) used alone, without chemotherapy, is effective for older women with early-stage hormone-positive breast cancer. The goal is to reduce the risk of cancer returning while avoiding the side effects of chemo.

NCT06361940Recruiting· Phase 2
Short-term hormone therapy before breast cancer surgery

This trial is testing how well a short course of hormone-blocking pills (endocrine therapy) works before surgery in women with early-stage hormone receptor-positive HER2-negative breast cancer. The goal is to understand what makes some cancers resistant to these treatments.

NCT05297617Recruiting· Phase 2
Shorter hormone therapy for low-risk postmenopausal breast cancer

This Phase 2 trial studies whether women with very low-risk, hormone-receptor positive breast cancer can safely take hormone therapy for a shorter time. It may help reduce side effects if shorter treatment works as well as the longer standard plan.

NCT07826052Not yet recruiting· Phase 2
Skipping chemotherapy for older women with hormone-positive breast cancer

This trial tests whether women aged 65 and older with a certain type of early breast cancer can safely skip chemotherapy and instead receive a pill that helps stop cancer cells from growing. The goal is to reduce treatment side effects while keeping the cancer from coming back.

NCT07311122Not yet recruiting
Hormone therapy for young women with early breast cancer

This study looks at young women with early-stage breast cancer who are premenopausal (still having periods) and have a low-to-intermediate Oncotype score, to see how well hormone therapy works. It aims to understand if current treatment decisions are appropriate.
