Pavia, PVAges 18 years+ - NCT07262138Recruiting
Active monitoring for older women with early breast cancer
This trial studies whether active monitoring (watchful waiting) can be a safe option instead of immediate surgery or other treatments for women 70 and older who have a small, slow-growing type of breast cancer. If you join, you will not have surgery or other treatments right away, but your cancer will be closely watched.
Pittsburgh, PennsylvaniaAges 70 years+ - NCT02610439Recruiting
Genetic testing to find causes of paclitaxel nerve damage
This study uses genetic tests on blood DNA to look for differences that may explain why some people develop nerve pain (peripheral neuropathy) from paclitaxel used for breast cancer. It compares people who got significant neuropathy during treatment with people who did not get neuropathy after completing paclitaxel.
Boston, MassachusettsAges Any age - NCT07400523RecruitingPhase 3
Ribociclib for breast cancer with leftover disease after chemo
This trial tests ribociclib, a targeted therapy, for women with hormone receptor-positive, HER2-negative breast cancer who still have cancer cells in the breast or lymph nodes after initial chemotherapy. It aims to reduce the chance of cancer coming back.
Zhanjiang, GuangdongAges 18 years+ - NCT07563621Recruiting
Understanding Vaginal Health Changes in Breast Cancer Survivors
This study examines vaginal dryness and discomfort—common side effects of breast cancer treatment—in women who've survived the disease. Researchers want to understand how often this happens and how much it affects daily life, which may help doctors better support survivors.
Hasselt, LimburgAges 18 years+ - NCT07514728Enrolling by invitation
Hyperbaric oxygen to slow breast cancer spread to lungs
This trial tests whether hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can slow the growth of breast cancer that has spread to the lungs. You would receive this treatment alongside standard care if your cancer has grown despite prior chemotherapy.
Jinan, ShandongAges 18–75 - NCT07292571Enrolling by invitationPhase 2
