Alexandria, VirginiaAges 18 years+ - NCT06846450RecruitingPhase 3
Comparing radiation types for nasopharyngeal cancer
This trial compares two types of radiation therapy (IMRT or IMPT plus CIRT) to see which works better for patients with nasopharyngeal cancer that hasn't spread. It's for people who have not had radiation to the head or neck before.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06014827RecruitingPhase 2
Targeted radiation and osimertinib for lung cancer with EGFR mutation
This trial tests a new approach for patients with advanced non-small cell lung cancer that has a specific EGFR mutation (Ex19del or L858R) and has started to grow again after at least six months on osimertinib. It combines two types of focused radiation with continued osimertinib to treat only the progressing spots while keeping the rest of the disease under control.
Duarte, CaliforniaAges 18 years+ - NCT06378866RecruitingPhase 2
Radiation with hormone therapy timing for prostate cancer
This study is testing whether using focused radiation beams (SBRT) right away or later, along with hormone therapy, can help control prostate cancer that has returned in a few spots outside the pelvis. The goal is to find the best timing for combining radiation and hormone treatment.
Phoenix, ArizonaAges 18 years+ - NCT03662373Recruiting
Monitoring system study for proton or carbon ion radiation
This trial checks whether a new monitoring system (called INSIDE) can safely work during proton or carbon ion radiation at CNAO. It may help improve how radiation is delivered and checked while treating certain head and skull cancers.
Pavia, PaviaAges 18 years+ - NCT04278118Recruiting
Proton radiation study for non-cancer brain tumor types
This trial tests a radiation plan that gives treatment in fewer, larger “fractions” using proton beams (or sometimes photon beams) for certain non-cancer brain tumor types. It aims to see how well this approach works while keeping side effects manageable.
Atlanta, GeorgiaAges 18 years+ - NCT05038332RecruitingPhase 2
Testing two types of radiation after prostate surgery
This Phase 2 study compares two schedules of radiation treatment after prostate surgery in men whose PSA starts rising again. It aims to see which radiation approach works well while tracking quality of life and safety.
Ann Arbor, MichiganAges 18 years+ - NCT05541016RecruitingPhase 2
Personalized lower-dose radiation for HPV-related throat cancer
This Phase 2 study tests whether giving a less intense (de-escalated) radiation plan can work for certain people with HPV-related oropharyngeal throat cancer. It uses HPV blood testing and scans to help guide treatment, aiming to keep cancer control while reducing treatment side effects.
Scottsdale, ArizonaAges 18 years+ - NCT05617716RecruitingPhase 2
Spine radiosurgery for painful cancer spread to the spine
This Phase 2 study tests a precise radiation treatment (spine SBRT, also called radiosurgery) to reduce pain from cancer that has spread to the spine. It focuses on people with stable spine structure and low pain at the start, to see how well the treatment works and stays safe.
Baltimore, MarylandAges 18 years+ - NCT05946213RecruitingPhase 3
Shorter radiation treatment for high-risk prostate cancer
This trial tests whether a shorter course of radiation works as well as the usual longer course for people with high-risk prostate cancer. The goal is to keep cancer control while possibly reducing treatment time and inconvenience.
Birmingham, AlabamaAges 18 years+ - NCT06392295RecruitingPhase 2
PSMA-Guided Radiation for Limited Prostate Cancer Return
This trial tests whether targeted radiation to the lymph nodes in the belly can help men whose prostate cancer has returned in just a few spots after prior radiation. You must have had a PSMA PET/CT scan showing the cancer is limited to pelvic or belly lymph nodes.
Miami, FloridaAges 18 years+ - NCT06500455RecruitingPhase 3
Standard vs longer radiation for brain metastases
This trial compares the usual short course of radiation therapy (one session) to a longer course (up to 5 sessions) for people with cancer that has spread to the brain. The goal is to see if the longer course works better and causes fewer side effects.
