This study tests a decision aid to help women 70 and older with early stage breast cancer choose their treatment. It looks at whether the tool helps patients and their doctors make a confident treatment choice.
Los Angeles, CaliforniaAges 18 years+ - NCT06890871Enrolling by invitationPhase 1/Phase 2
Radiation with immunotherapy and anti-angiogenic therapy for advanced HER2-negative breast cancer
This trial tests a combination of radiation therapy, immunotherapy, and a drug that blocks blood vessel growth for advanced HER2-negative breast cancer that has spread. It is for patients whose cancer has worsened after at least two prior treatments.
Wuhan, HubeiAges 18–75 - NCT05896865Recruiting
Personalized breast cancer radiation based on tumor biology
This trial studies whether adjusting radiation dose using how the tumor behaves can improve outcomes for people with locally advanced breast cancer that has spread to certain nearby lymph nodes. It may help deliver the right radiation intensity while avoiding unnecessary exposure.
SeoulAges 19 years+ - NCT05907681Recruiting
Study outcomes after precise targeted radiation for metastatic breast cancer
This study follows people with breast cancer that has spread to other parts of the body who receive a highly precise form of radiation (like IMRT, SBRT, or proton therapy). It aims to see how well this treatment strategy works and what outcomes patients experience.
SeoulAges 19–100 - NCT05933733Recruiting
Salvage treatment for breast cancer that returned locally
This trial looks at how well “salvage” treatments work for breast cancer that has come back only in the local area (like the chest wall or nearby lymph nodes), without spreading to distant organs. It also tracks side effects to better understand the risks and benefits for patients who need additional treatment.
SeoulAges 18–100 - 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+ - NCT06888388Recruiting
Safety of nipple-sparing mastectomy for women with high-risk genes
This study looks at the long-term safety of a type of breast surgery (nipple-sparing mastectomy) in women who carry certain inherited gene changes (BRCA1, BRCA2, PALB2, TP53, CDH1, or PTEN) that increase their risk of breast cancer. The goal is to understand how safe this surgery is over time for these women.
New Haven, ConnecticutAges 18–90 - NCT06885671Recruiting
Shorter vs fewer radiation sessions for breast cancer
This trial compares two types of partial breast radiation: one session versus several shorter sessions. It aims to see if a single treatment is as effective and more convenient for women with early-stage breast cancer.
