Proton Collaborative Group

This study tests whether a higher dose of proton radiation, given alongside oral chemotherapy, can help people with pancreatic cancer that cannot be removed by surgery. The goal is to shrink tumors enough to allow surgery and improve survival. About 60 adults with inoperable or b…

This study tests whether proton radiation, a precise type of radiation, can control early-stage breast cancer while causing fewer side effects than standard radiation. About 132 women aged 50 and older with certain types of breast cancer will receive proton therapy only to the ar…

This study tests if a shorter, 3-week course of proton radiation is as safe and effective as the standard 5-week course for women with breast cancer who also need radiation to nearby lymph nodes. About 276 participants will receive either the shorter or longer treatment. The goal…

This study looks at two treatments for men with intermediate-risk prostate cancer that hasn't spread. One group gets proton beam radiation alone (28 sessions), and the other gets the same radiation plus hormone therapy. The goal is to see if adding hormones helps keep the cancer …

This study looks at how well proton radiation (and sometimes hormone therapy) works for prostate cancer that has come back or is at risk of coming back after surgery. About 70 men whose cancer has not spread will receive this treatment. The main goal is to measure short-term side…

This study gathers information from 40,000 people receiving radiation therapy for cancer. Researchers will analyze the data to understand what works best and how to reduce side effects. The goal is to improve future treatment and care for patients.
