Surgery has been historically the mainstay treatment for advanced pre-malignant lesions and early esophageal cancers. However, esophagectomy is associated with significant morbidity and mortality. With the advance of therapeutic endoscopy, there has been a growing interest and application of endoscopic resection and mucosal ablative techniques for the treatment of these diseases. Esophageal stricture(ES) formation has become an increasingly recognized complication of extensive endoscopic mucosal ablation and/or resection. The resultant symptomatic stricture development can significantly impair a patient's quality of life. Endoscopic therapy of esophageal strictures with balloon dilation and/or local steroid injection is invasive, costly, and associated with the potential ...

The purpose of this study is to assess how well paclitaxel, with or without cixutumumab, works for treating patients who have esophageal cancer or gastroesophageal junction cancer that has spread to other places in the body. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Cixutumumab may kill cancer cells by blocking the action of a protein needed for cancer cell growth. Giving paclitaxel with or without cixutumumab may kill more tumor cells.

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 ...

The purpose of this study is to evaluate how well proton beam radiation therapy compared with intensity modulated photon radiotherapy works in treating patients with stage I-IVA esophageal cancer. Proton beam radiation therapy uses a beam of protons (rather than x-rays) to send radiation inside the body to the tumor without damaging much of the healthy tissue around it. Intensity modulated photon radiotherapy uses high-energy x-rays to deliver radiation directly to the tumor without damaging much of the healthy tissue around it. It is not yet known whether proton beam therapy or intensity modulated photon radiotherapy will work better in ...

Falls are common and catastrophic in cancer patients. Cancer patients are vulnerable to falls due to muscle loss. In prescribing exercise in a data driven manner to cancer patients, our hypothesis is this "prescription" for exercise will eventually be demonstrated to reduce the occurrence of injurious falls.
