Recruiting studies
- NCT06260033RecruitingPhase 2
Radiation Therapy for Oligoprogressive ER+ Breast Cancer
This trial tests whether a precise radiation treatment (SBRT) can target a few growing spots of estrogen receptor-positive breast cancer that has spread to other parts of the body. It also uses a special PET scan (FES PET/CT) to see how well the cancer responds. The goal is to slow down the cancer and delay the need for stronger treatments.

Beijing, Beijing MunicipalityAges 18 years+ - NCT06400563Recruiting
MRg-NIRS breast cancer imaging study for small tumors
This study tests a new imaging method that combines MRI with light scanning to get better pictures of breast cancer before surgery. You may qualify if you have a recent breast cancer diagnosis with a tumor that is 2 cm or smaller and can have an MRI.
Lebanon, New HampshireAges 18–83 - NCT06401421Recruiting
Blood test for tumor DNA after breast cancer chemo
This study tests a new blood test to see if it can find tiny bits of tumor DNA after chemotherapy. If you have a larger or higher-risk breast cancer and are getting chemotherapy before surgery, you may join. The test could help doctors know if your cancer is gone or if more treatment is needed.
Anchorage, AlaskaAges 18 years+ - NCT06404697RecruitingPhase 2
Extra radiation to lymph nodes above collarbone for high-risk breast cancer
This trial tests giving a focused, higher dose of radiation to the lymph nodes above the collarbone after breast cancer treatment. It is for patients whose cancer did not fully disappear from those nodes after pre-surgery chemotherapy, to see if extra radiation can help prevent recurrence.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06404983Recruiting
Opioid-free anesthesia for breast cancer surgery
This study tests whether breast cancer surgery can be done safely without using opioid pain medicines during anesthesia. The goal is to see if avoiding opioids leads to fewer side effects and a smoother recovery.
Ioannina, EpirusAges 18–99 - NCT06409390RecruitingPhase 2
Sequential therapy based on tumor evolution for breast cancer
This trial tests a sequence of different treatments for breast cancer that has spread, based on how the cancer evolves. The goal is to find a personalized treatment plan that may work better over time.
Tampa, FloridaAges 18 years+ - NCT06452394RecruitingPhase 2
Testing doxycycline with chemo for breast cancer
This trial tests whether adding the antibiotic doxycycline to standard chemotherapy before surgery can better target breast cancer stem cells in people with ER-positive, HER2-negative breast cancer. The goal is to improve treatment response.
Sankt Gallen, Canton of St. GallenAges 18 years+ - NCT06471452Recruiting
Living Better After Breast Cancer Treatment
This study is for people who have completed breast cancer treatment and want to improve their quality of life. It tests ways to help you feel better and live well after treatment.

Skin Changes in Breast Cancer Patients on Hormone Therapy or Chemotherapy
This study measures how your skin changes physically and mechanically during breast cancer treatment. It may help doctors better manage side effects like skin dryness or tightness.
MilanAges 40–70 - NCT06491680RecruitingPhase 4
Heart safety during breast cancer chemo
This trial checks how well the heart handles anthracycline chemotherapy in breast cancer patients. It helps doctors find early signs of heart side effects so they can keep you safe during treatment.
Cairo, Cairo GovernorateAges 18–60 - NCT06508307RecruitingPhase 1
A study of an injected virus for advanced solid tumors
This trial tests a new treatment where a virus (GC001) is injected directly into a tumor. The virus is designed to attack cancer cells and may help people with advanced solid tumors that haven't responded to other treatments.
Zhengzhou, HenanAges 18–75 - NCT06536881Recruiting
Diet and gut health during breast cancer chemo
This study looks at how changing your diet during chemotherapy affects side effects and your body's energy use. It involves providing stool samples to study gut bacteria.
