Proton Collaborative Group

This study tests proton radiation therapy for men with prostate cancer that has returned or is at risk of returning after prostate removal surgery. Researchers want to see if this precise type of radiation can control the cancer while causing fewer side effects than standard radi…

This study tests proton radiation therapy for women with early-stage breast cancer. The goal is to see if targeting only the tumor area can keep cancer from coming back while causing fewer side effects. About 132 women aged 50 and older will take part. Researchers will track recu…

This study compares a 3-week course of proton radiation to the standard 5-week course for women with breast cancer who need radiation to the breast or chest wall and nearby lymph nodes. The goal is to see if the shorter schedule causes fewer severe skin and tissue side effects wh…

This phase 2 trial tests whether a higher dose of proton radiation combined with the oral chemotherapy drug capecitabine can help people with unresectable pancreatic cancer live longer and possibly become candidates for surgery. The study enrolls 60 patients whose tumors cannot b…

This phase 3 study is testing whether adding a short course of hormone therapy (androgen suppression) to image-guided radiation therapy helps men with intermediate-risk prostate cancer. About 192 men will receive either radiation alone or radiation plus hormone therapy. The goal …

This study is collecting information from up to 40,000 cancer patients who are receiving radiation therapy. Researchers will track their outcomes to better understand what works and how to reduce side effects. The goal is to improve patient care by learning from real-world treatm…
