This trial tests giving alectinib first, then adding targeted radiation to remaining spots of cancer in people with ALK-rearranged advanced non-small cell lung cancer. It aims to control the cancer after an initial response and help keep disease from progressing.
StockholmAges 20 years+ - NCT03034187Recruiting
Track side effects after prostate cancer radiation
This study follows people with prostate cancer who receive radiation to understand what side effects and quality-of-life changes happen over time. It may help improve standard follow-up care by better tracking radiation-related toxicity.
GroningenAges 18 years+ - NCT05624099RecruitingPhase 2
Camrelizumab plus chemoradiotherapy for advanced esophageal cancer
This study tests whether adding camrelizumab (an immune treatment) to standard chemoradiotherapy can control advanced esophageal squamous cell cancer. It is meant for people who have not had any prior whole-course cancer medicines for this cancer stage.
FuzhouAges 18–75 - NCT06116019Recruiting
Online adaptive radiotherapy for cancer patients
This trial tests a new radiation therapy machine that adjusts the radiation plan in real-time based on changes in your body. It may help make treatment more precise and reduce side effects.
BerlinAges 18 years+ - NCT04832620Recruiting
Using MRI-guided planning to improve proton radiation for rare bone tumors
This trial is testing a better way to plan proton radiation using MRI images, aiming to deliver treatment more accurately for chordoma or chondrosarcoma in the spine/sacrum area. You may benefit if the trial’s planning method helps target the tumor while sparing nearby healthy tissue.
Delft, South HollandAges 50 years+ - NCT05794035Recruiting
Shorter radiation after skin cancer surgery for older adults
This study looks at whether giving a shorter course of radiation after surgery can help prevent skin cancer from coming back in people age 70 and older. It focuses on higher-risk skin cancers and checks how well the treatment works and what side effects occur.
CréteilAges 70 years+ - NCT06144346Recruiting
Radiation for limited breast cancer spread
This trial tests whether treating each spot of cancer that has spread (but only a few spots) with focused radiation can help control breast cancer. It aims to see if this approach can stop the cancer from growing further without needing strong whole-body treatments right away.
CairoAges 18–70 - NCT05258448Recruiting
Chemo-radiotherapy for advanced, non-surgical lung cancer
This trial studies treatment that combines chemotherapy and radiation for people with advanced lung cancer that cannot be removed with surgery. It may help improve cure chances for patients who can complete the study tests, including heart scans.
Odense CAges 18 years+ - NCT04992780RecruitingPhase 2
Hypo-fractionated radiation versus standard radiation for lung cancer
This study compares two different radiation schedules for stage III non-small cell lung cancer, both combined with chemotherapy and immunotherapy. It aims to see whether giving radiation in a different way can work as well (or better) and be safe while treating the cancer.
Kansas City, KansasAges 18 years+ - NCT03908684Recruiting
Ultrasound tests to predict early response to prostate and head/neck radiation
This study uses special ultrasound imaging to look for early signs of how well radiation treatment is working in prostate, rectum, and head/neck cancers. It may help doctors spot response sooner and adjust care earlier if needed.
Toronto, OntarioAges Any age - NCT05349552Recruiting
Radiation for lung or chest cancers in specific locations
This trial studies how safe and effective a type of focused radiation called SBRT is for cancer tumors in certain chest locations. It’s meant for people whose tumor is small (up to 5 cm) and who don’t have widespread, uncontrolled spread.
Beijing, Beijing MunicipalityAges 18–80 - NCT07173387RecruitingPhase 2
