Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04595019Recruiting
Shorter faster radiation with hormone treatment for prostate cancer
This trial studies a more sped-up radiation schedule for men with certain local prostate cancers, given together with hormone therapy. It aims to keep cancer control while possibly reducing treatment time and making care easier.
Sutton, SurreyAges 18 years+ - NCT04603209Recruiting
Check-in registry for radiation during breast-conserving surgery
This registry study tracks people with early-stage, single-area breast cancer to understand outcomes when radiation is given during breast-conserving surgery. It may help doctors improve treatment planning for patients like you.
Santa Monica, CaliforniaAges 18 years+ - NCT04620187RecruitingPhase 2
Study medicine T-DM1 after surgery for HER2-positive salivary cancer
This Phase 2 trial studies T-DM1 given after surgery for salivary gland cancer that is HER2-positive. The goal is to reduce the risk of the cancer coming back by targeting HER2-positive tumor cells.
Atlanta, GeorgiaAges 18 years+ - NCT04625907RecruitingPhase 1/Phase 2
Study testing treatment options for children and adults with RMS
This study tests different treatment approaches for rhabdomyosarcoma (RMS) in children and adults, including newly diagnosed high-risk cases, people needing radiotherapy, and people whose RMS has returned. It’s designed to find safer dosing and more effective therapy while checking whether participants can proceed based on health and timing requirements.
BrisbaneAges Any age - NCT04642027RecruitingPhase 3
PSMA scan-guided salvage radiation after prostate surgery
This trial tests whether using a specialized PSMA PET scan to guide radiation can better treat prostate cancer that returns after prostate surgery. It targets the “prostate bed” area with a shorter, stronger radiation schedule (hypofractionated) to control rising PSA levels.
Arnhem, GelderlandAges 18–80 - NCT04654338RecruitingPhase 2/Phase 3
Two types of targeted radiation for favorable prostate cancer
This trial tests whether two “ablative” (high-dose, focused) radiation treatments can work well for men with favorable-risk prostate cancer. It looks at whether the treatments are practical and safe, especially for urinary side effects.
Toronto, OntarioAges Any age - NCT04669873Recruiting
Partial breast radiation vs whole breast radiation after lumpectomy
This trial studies whether treating only part of the breast with radiation works as well as treating the whole breast in people with early breast cancer after lumpectomy. It may help reduce radiation exposure to healthy tissue, while still controlling the cancer.
São Paulo, São PauloAges 50–90 - NCT04679454Recruiting
One-dose pre-surgery radiation for early breast cancer
This study tests whether giving a single dose of radiation before breast surgery can be safe and effective for early-stage breast cancer. It may help by shrinking or treating the tumor right before the operation, depending on your case.
