Henan, HenanAges 18–70 - NCT07551596RecruitingPhase 2
Two immunotherapy drugs for colorectal cancer with residual disease
This trial tests a combination of two immunotherapy drugs to see if they can stop colorectal cancer from returning after standard treatment. It is for people who still have cancer DNA in their blood after surgery and/or chemotherapy, which means they are at high risk of the cancer coming back.
New Orleans, LouisianaAges 18 years+ - NCT07527741Recruiting
HER2-Positive Breast Cancer Treatment Patterns Study
This study tracks how patients with HER2-positive early-stage breast cancer receive treatment and stick to their treatment plan after their care moves to local hospitals. The trial helps doctors understand whether patients follow through with their recommended therapy when treated closer to home.
Loznica, Bolnička 65Ages 18 years+ - NCT07527689Recruiting
Faster vs. Standard Radiation After Breast Cancer Surgery
This study compares two radiation schedules for breast cancer patients at high risk of cancer returning in lymph nodes. Both use modern radiation therapy, but one delivers treatment faster (ultra-hypofractionated) while the other uses a more moderate schedule. The goal is to see which approach works better with fewer side effects.
ShanghaiAges 18 years+ - NCT07503496Recruiting
Biobran supplement for breast cancer chemo support
This trial tests if a supplement called Biobran (made from rice bran) can help support people with breast cancer who are receiving chemotherapy. It may reduce side effects or improve treatment tolerance.
TaichungAges 20–65 - NCT06776458Recruiting
Aromatase inhibitor effects on heart and brain health in breast cancer
This study looks at how aromatase inhibitors (a type of hormone therapy for breast cancer) affect your heart and brain health over time. It compares women with breast cancer who have taken these drugs to healthy women of similar age.
Toronto, OntarioAges Any age - NCT07474090Recruiting
Personalized Exercise Program for Breast Cancer Survivors
This study tests whether a personalized exercise program during chemotherapy helps breast cancer survivors recover better and feel stronger. You'll use a smartphone app to do guided workouts at home while getting support from exercise coaches.
Winston-Salem, North CarolinaAges 18–85 - NCT07469267Recruiting
Armpit radiation vs more surgery for early breast cancer with node spread
This trial tests whether radiation to the lower armpit (level I-II axilla) works as well as more extensive surgery for women with early-stage breast cancer that has spread to one or two sentinel lymph nodes (with cancer size > 2 mm). It aims to find a gentler treatment that still keeps the cancer from coming back.
Guiyang, GuizhouAges 18 years+ - NCT07460752RecruitingPhase 2
Alternative injection site for goserelin in breast cancer patients
This trial is testing whether giving the drug goserelin in a different spot on the body works just as well for suppressing ovarian function in premenopausal women with hormone receptor positive breast cancer. You may be a fit if you've already been on goserelin shots in your abdomen for at least 6 months.
Rochester, MinnesotaAges 18–50 - NCT07443943RecruitingPhase 2
Potato starch supplement for joint pain from hormone therapy
This trial studies whether a dietary supplement made from resistant potato starch can help reduce joint and muscle pain in people who are about to start aromatase inhibitor therapy for breast cancer or high risk. You take the supplement daily and report how you feel over 24 weeks.
Ann Arbor, MichiganAges Any age - NCT07439458Recruiting
Exercise effects on tumor cells in breast cancer survivors
