This study tests a way to give radiation therapy that avoids the ovaries as much as possible, to help preserve fertility and hormone function in young women.
St Louis, MissouriAges 18–50 - NCT06800989Recruiting
Can sophrology with a wearable device reduce chemo anxiety?
This study tests whether a relaxation technique called sophrology, guided by a wearable device, can help reduce anxiety during chemotherapy for early-stage breast cancer. It aims to offer extra support during treatment.
AngersAges 18 years+ - NCT06876714RecruitingPhase 3
Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response
This trial compares 6 months versus 12 months of HER2-targeted therapy for people with HER2+ breast cancer who had a complete response after chemo and trastuzumab. The goal is to see if a shorter treatment is just as effective.
Phoenix, ArizonaAges 18 years+ - NCT06860529RecruitingPhase 2
Immunotherapy plus chemo for early-stage HR+/HER2- breast cancer
This trial tests adding the immunotherapy drug serplulimab to standard chemotherapy for people with early-stage HR-positive, HER2-negative breast cancer. It aims to see if this combination can improve outcomes before surgery.
Zhengzhou, HenanAges 18 years+ - NCT06858449Recruiting
Exercise and protein during chemo for breast cancer
This study tests whether adding resistance training (like lifting weights) along with a protein shake after workouts can help women with breast cancer maintain muscle and bone health while they receive chemotherapy before surgery.
Pittsburgh, PennsylvaniaAges 20–89 - NCT06855654Recruiting
Building resilience in women with breast cancer
This study tests a counseling program designed to help women with metastatic breast cancer build resilience and cope better. If you've been diagnosed within the last 6 months and get your cancer care at UNC, you may be eligible.
Birmingham, AlabamaAges 18 years+ - NCT06846814Enrolling by invitation
Ultrasound after contrast mammography to check extra breast lesions
This trial tests whether doing a follow-up ultrasound after a special type of mammogram (contrast-enhanced mammography) can better understand extra breast spots that need more checking. It might help doctors give a clearer diagnosis.
NaplesAges 18 years+ - NCT06843096Enrolling by invitation
Special mammogram for finding breast cancer when origin is unknown
This trial uses a special mammogram with contrast dye to look for breast cancer in people who have cancer that started somewhere unknown (called Cancer of Unknown Primary). It may help find if the breast is the source, which could guide treatment.
RomeAges 18 years+ - NCT06843083Enrolling by invitation
Which advanced breast scan is better for you?
This study compares two advanced breast imaging methods—contrast-enhanced mammography (CEM) and breast MRI—to see which is better at finding cancer, especially in women with dense breasts or unclear mammogram results. If you are being referred for one of these exams, you may be able to join and help doctors learn which test works best.
NaplesAges 18 years+ - NCT06833502RecruitingPhase 2
Screening for breast cancer spread after chemo and surgery
This trial aims to find out if doing special scans to check for breast cancer spread to organs (not just lymph nodes) is helpful in certain patients. The study looks at people with breast cancer that had already spread to lymph nodes and did not completely go away with chemotherapy and surgery.
Tampa, FloridaAges 18 years+ - NCT06834204Enrolling by invitation
Better care coordination for cancer survivors
This study tests a program to improve communication between your cancer team and your regular doctor. If you have heart or diabetes risks and you're being treated for breast, prostate, bladder, or endometrial cancer, this trial may help coordinate your care.
New Brunswick, New JerseyAges 18 years+ - NCT06807749Recruiting
Adjuvant treatment for premenopausal breast cancer
This trial looks back at premenopausal women with early-stage, hormone-positive, HER2-negative breast cancer who had surgery and an Oncotype DX test, to see how different treatments affected their outcomes. If you fit this group, your past medical records could help researchers learn more about the best treatments.
Roma, Antonella PalazzoAges Up to 60 years - NCT06806930RecruitingPhase 2
Predicting response to hormone therapy before breast cancer surgery
This trial tests whether we can predict how well hormone therapy works before surgery for early-stage breast cancer. It may help women with estrogen receptor-positive, HER2-negative or HER2-low breast cancer avoid or tailor treatments.
Washington D.C., District of ColumbiaAges 21 years+ - NCT06797635RecruitingPhase 2
Study of Patritumab Deruxtecan and Pembrolizumab for High-Risk Early Breast Cancer
This trial tests a combination of targeted therapies (patritumab deruxtecan plus pembrolizumab) along with other anticancer drugs for people with a high-risk type of early-stage breast cancer that is either triple-negative or has very low hormone receptors and is HER2-negative. The goal is to see if this approach can help prevent the cancer from coming back.
Santa Monica, CaliforniaAges 18 years+ - NCT06802172Recruiting
Timing meals during cancer treatment for Alaska Native patients
This study tests whether scheduling meals at specific times of day can improve how patients feel during cancer treatment. It is for Alaska Native or American Indian people with certain cancers (rectal, HER2+ or triple negative breast, or other solid tumors) who are receiving neoadjuvant (before surgery) or adjuvant (after surgery) therapy.
Anchorage, AlaskaAges 21 years+ - NCT06781996RecruitingPhase 3
