2 Clinical Trials for Various Conditions
This phase III trial studies how well the addition of radiotherapy to the usual treatment (chemotherapy) works compared to the usual treatment alone in treating patients with esophageal and gastric cancer that has spread to a limited number of other places in the body (oligometastatic disease). Radiotherapy uses high energy x-rays, gamma rays, or protons to kill tumor cells and shrink tumors. Drugs used in usual chemotherapy, such as leucovorin, 5-fluorouracil, oxaliplatin, and capecitabine, 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. Adding radiotherapy to the usual chemotherapy may work better compared to the usual chemotherapy alone in treating patients with esophageal and gastric cancer.
This phase II trial studies how well chemotherapy with or without radiation or surgery works in treating participants with esophageal or gastric cancer that has spread to less than 3 places in the body (oligometastatic). Drugs used in chemotherapy, such as fluorouracil and capecitabine, 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. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Surgery, such as complete surgical resection, may stop the spread of tumor cells by surgically removing organs or tumors. Giving chemotherapy with radiation or surgery may work better than chemotherapy alone in treating participants with oligometastatic esophageal or gastric cancer.
