Currently, only a few international institutions use CIRT to treat pelvic bone sarcomas. Accordingly, data evaluating the potential differences in oncological outcomes, toxicities, and functional outcomes between CIRT and the more readily accessible local therapies of surgery and PT is scarce. For this reason, we propose conducting a prospective comparative effectiveness study evaluating functional outcomes, toxicities, and local control in patients with pelvic bone sarcomas treated with surgery, PT, and CIRT.

The purpose of this study is to demonstrate non-inferiority of pCR with hypofractionated radiotherapy and concurrent FOLFOX compared to historical controls.

The purpose of this study is to determine the safety and effectiveness of 5 fraction stereotactic pencil beam scanning proton radiotherapy for the treatment of hepatocellular carcinoma (HCC).

This randomized phase III trial studies how well radiation therapy, paclitaxel, and carboplatin with or without trastuzumab work in treating patients with esophageal cancer. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether giving radiation therapy and combination chemotherapy together with or without trastuzumab is more effective in treating esophageal cancer.

RATIONALE: Stereotactic radiosurgery may be able to send x-rays directly to the tumor and cause less damage to normal tissue. Radiation therapy uses high-energy x rays to kill tumor cells. It is not yet known whether stereotactic radiosurgery is more effective than whole-brain radiation therapy in treating patients with brain metastases that have been removed by surgery.

PURPOSE: This randomized phase III trial studies how well stereotactic radiosurgery works compared to whole-brain radiation therapy in treating patients with brain metastases that have been removed by surgery.

This randomized phase II clinical trial studies how well nivolumab after combined modality therapy works in treating patients with high risk stage II-IIIB anal cancer. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread.

The purpose of this study is to demonstrate non-inferiority of pCR with hypofractionated radiotherapy and concurrent FOLFOX compared to historical controls.
