This trial studies a type of focused radiation given in smaller parts to treat bone metastases from breast cancer. It may help shrink tumors and improve control of pain or growth when standard treatments haven’t worked or surgery isn’t possible.
Shanghai, Shanghai MunicipalityAges Any age - NCT04985032Recruiting
Radiation after lumpectomy for selected breast tumors
This trial tests a shorter, focused type of radiation (APBI using SBRT) after lumpectomy for certain early breast cancers. It may help by targeting only the part of the breast where the tumor was, rather than treating the whole breast, while keeping safety and cancer control in mind.
Stuart, FloridaAges 50–100 - NCT05624996RecruitingPhase 3
Targeted high-dose radiation added to standard lung cancer treatment
This trial tests whether adding high-dose, targeted radiation to the usual treatment helps people with locally advanced, non-operable lung cancer live longer or better control the cancer. It may help shrink tumors in the chest and improve outcomes when surgery can’t be done.
Birmingham, AlabamaAges 18 years+ - NCT05879653RecruitingPhase 2
Pembrolizumab, drug EV, and radiation for bladder cancer
This Phase 2 study tests how well pembrolizumab and an antibody-drug medicine (EV) given with bladder radiation work for non-metastatic bladder cancer that is mostly urothelial. It may help some people control the cancer without it spreading to other organs.
Kobe, HyōgoAges 18 years+ - NCT06025747RecruitingPhase 1
Abemaciclib plus radiation for liposarcoma before surgery
This trial tests a combination of the targeted drug abemaciclib and radiation therapy before surgery for people with a specific type of liposarcoma. The goal is to see if this combination can shrink the tumor and help make surgery more effective.
Seattle, WashingtonAges 18 years+ - NCT07202273Recruiting
One-time radiation treatment for painful bone metastases
This trial tests a single session of radiation therapy to relieve pain and improve stability in up to two bone spots where cancer has spread. The goal is to make treatment faster and more convenient for patients.
Salt Lake City, UtahAges 18 years+ - NCT05996107RecruitingPhase 1
Ribociclib with radiation for high-risk HR+ breast cancer
This trial tests whether adding the targeted therapy ribociclib (Kisqali) to radiation after surgery reduces the risk of breast cancer returning in patients with high-risk, hormone-positive breast cancer.
Ann Arbor, MichiganAges 18 years+ - NCT04525989Recruiting
Short-course proton vs photon radiation before rectal surgery
This study compares two types of pre-surgery radiation—protons versus standard photons—in people with high-risk rectal cancer. The goal is to shrink and control the tumor while safely getting you ready for surgery, and to see which approach works better.
Stockholm, SolnaAges 18 years+ - NCT04545957Recruiting
Radiation planning study using MRI for adults with cancer
This trial tests a “master protocol” approach to use MRI (a detailed body scan) to help plan radiation treatment for people with cancer. It may help doctors customize radiation more accurately, depending on your specific cancer type.
Boston, MassachusettsAges 18 years+ - NCT04894188Recruiting
Hormone plus radiation before prostate surgery for high-risk cancer
This trial studies giving hormone treatment and radiation before prostate surgery to treat high-risk, locally advanced prostate cancer. It aims to improve cancer control by shrinking or controlling the tumor before removing it.
Douliu City/Huwei Township, Yunlin CountyAges 20–75 - NCT05596630Recruiting
Stereotactic radiation for small liver cancer recurrence safety
This trial tests a precise type of radiation to treat small liver cancer that has come back after prior treatment. It aims to help with safety and long-term outcomes while protecting nearby organs and healthy liver.
Hangzhou, ZhejiangAges 18–80 - NCT05528133RecruitingPhase 2
Personalized radiation based on tumor genetics in triple-negative breast cancer
This trial tests whether using tumor “genetics” (information from your biopsy) to guide radiation planning can improve treatment for triple-negative breast cancer. It may help by aiming radiation more precisely while still using standard approaches where needed.
Clearwater, FloridaAges 18 years+ - NCT05754580Recruiting
Boost radiation for intermediate or higher-risk prostate cancer
This study tests a stronger, focused radiation plan for intermediate to higher-risk prostate cancer. It combines a high-dose internal radiation “boost” with external radiation to try to improve cancer control while keeping side effects manageable.
Omaha, NebraskaAges 19 years+ - NCT05764720Recruiting
Personalized targeted radiation for borderline pancreatic cancer
This study tests a personalized form of stereotactic radiation therapy (high-precision radiation planned to fit your tumor) after you’ve had some chemotherapy. It aims to treat pancreatic tumors while limiting exposure to nearby healthy organs.
Birmingham, AlabamaAges 18 years+ - NCT06472583RecruitingPhase 2
Immunotherapy and radiation before breast cancer surgery
This trial tests giving immunotherapy combined with a precise, high-dose radiation boost before surgery for HER2-negative breast cancer. The goal is to see if this approach can improve outcomes, especially for cancers that are more advanced or have spread to a few other spots in the body.
GliwiceAges 18 years+ - NCT02701153Recruiting
Short pre-surgery radiation for soft-tissue sarcoma
This trial tests a short course of radiation before surgery to shrink a soft-tissue sarcoma and make it easier to remove. It may help by improving how well the tumor can be removed, while studying safety and effectiveness for this cancer type.
Los Angeles, CaliforniaAges 18 years+ - NCT07635238RecruitingPhase 2
