Shorter radiation after lumpectomy for early breast cancer
This trial tests a shorter, more intense course of daily radiation therapy (called ultra hypo-fractionation) given after lumpectomy for early-stage breast cancer. The goal is to reduce the number of treatment visits while keeping the same high level of effectiveness and safety.
Chapel Hill, North CarolinaAges 50 years+ - NCT06911528Recruiting
New cell-probing technology for early breast cancer surgery
This trial tests a new technology that helps doctors examine cells during surgery for early-stage breast cancer. It may help make the sentinel lymph node biopsy more accurate.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06946238Recruiting
Single-dose radiation after surgery for low-risk breast cancer
This trial tests giving a single, very targeted dose of radiation right after surgery for early-stage breast cancer. It is for women age 40+ with small, low-risk tumors (Luminal A or B) that have been fully removed and have not spread to lymph nodes.
MilanAges 40 years+ - NCT06961955RecruitingPhase 2
Shorter versus longer whole breast radiation for early-stage breast cancer
This trial compares a 5-day course of whole breast radiation plus a boost to the standard 9-day course for people with early-stage breast cancer who have certain risk factors, such as high-grade tumors or younger age. The goal is to see if the shorter treatment is just as safe and effective.
Salt Lake City, UtahAges 18 years+ - NCT06984250Recruiting
Shorter radiation with extra focus on tumor site for breast cancer
This trial tests a shorter course of radiation therapy that includes an extra dose to the tumor site for women with early-stage breast cancer. It aims to make treatment more convenient and effective after breast-conserving surgery.
Taipei, TaiwanAges 20–85 - NCT07017673RecruitingPhase 2
