Chemotherapy With or Without Surgery in Treating Patients With Metastatic Colorectal Cancer That Cannot Be Removed by Surgery
Ontology highlight
ABSTRACT: RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether chemotherapy is more effective when given alone or together with surgery in treating patients with colorectal cancer.
PURPOSE: This randomized phase II/III trial is studying how well chemotherapy works and compares it with surgery followed by chemotherapy in treating patients with metastatic colorectal cancer that can not be removed by surgery.
Project description:This randomized phase II trial studies how well liver surgery and chemotherapy compared to chemotherapy alone work in treating patients with colorectal cancer that has spread to the liver (liver metastases) that can be removed by surgery and that has spread to the lungs (lung metastases) that cannot be removed by surgery. Liver surgery removes a portion of the liver affected by the tumor. Chemotherapy drugs 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. Liver surgery and chemotherapy may work better than chemotherapy alone in treating patients with colorectal cancer which has spread to the liver and lungs.
Project description:RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, leucovorin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known which combination chemotherapy regimen is more effective in treating colorectal cancer.
PURPOSE: This randomized phase II/III trial is studying two combination chemotherapy regimens to compare how well they work in treating patients with metastatic colorectal cancer that cannot be removed by surgery.
Project description:RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, leucovorin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery.
PURPOSE: This phase II trial is studying giving oxaliplatin, leucovorin, and fluorouracil together, before and after radiation therapy and surgery in treating patients with rectal cancer that can be removed by surgery.
Project description:RATIONALE: Drugs used in chemotherapy, such as tegafur-uracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. Sometimes, after surgery, the tumor may not need more treatment until it progresses. In this case, observation may be sufficient. It is not yet known whether chemotherapy is more effective than observation in treating colorectal cancer.
PURPOSE: This randomized phase III trial is studying tegafur and uracil to see how well they work compared to observation in treating patients with stage II colorectal cancer that has been completely removed by surgery.
Project description:RATIONALE: Monoclonal antibodies, such as bevacizumab, 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. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with combination chemotherapy may kill more tumor cells.
PURPOSE: This phase III trial is studying how well giving induction therapy with bevacizumab together with combination chemotherapy with or without capecitabine followed by bevacizumab maintenance therapy in treating patients with metastatic colorectal cancer that cannot be removed by surgery.
Project description:RATIONALE: Drugs used in chemotherapy, such as fluorouracil, leucovorin, and oxaliplatin, 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 bevacizumab, 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. Bevacizumab may also stop the growth of colon cancer by blocking blood flow to the tumor. Giving combination chemotherapy together with bevacizumab may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with bevacizumab works in treating patients with stage IV colon cancer that cannot be removed by surgery.
Project description:RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as capecitabine, oxaliplatin, fluorouracil, and leucovorin, 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 cetuximab, 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. Giving radiation therapy together with combination chemotherapy and cetuximab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy and cetuximab after surgery may kill any tumor cells that remain after surgery.
PURPOSE: This phase II clinical trial is studying how well giving radiation therapy together with chemotherapy and cetuximab followed by surgery, chemotherapy, and cetuximab works in treating patients with locally advanced or metastatic rectal cancer that can be removed by surgery.
Project description:RATIONALE: Monoclonal antibodies, such as bevacizumab, 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. Bevacizumab may also stop the growth of colorectal cancer by blocking blood flow to the tumor. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with combination chemotherapy may kill more tumor cells. It is not yet known which combination chemotherapy regimen is more effective when given together with bevacizumab in treating patients with colorectal cancer.
PURPOSE: This randomized phase II trial is studying bevacizumab to compare how well it works when given together with two different combination chemotherapy regimens as first-line therapy in treating patients with metastatic colorectal cancer that cannot be removed by surgery.
Project description:RATIONALE: Drugs used in chemotherapy, such as capecitabine and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Monoclonal antibodies, such as cetuximab, 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. Cetuximab may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether giving capecitabine and oxaliplatin together with cetuximab is more effective than capecitabine and oxaliplatin in treating colorectal cancer.
PURPOSE: This randomized phase II trial is studying how well giving capecitabine and oxaliplatin together with cetuximab works compared to capecitabine and oxaliplatin in treating patients with metastatic colorectal cancer that cannot be removed by surgery.
Project description:This randomized phase II trial studies how well paclitaxel with or without carboplatin and/or bevacizumab followed by doxorubicin and cyclophosphamide works in treating patients with breast cancer that can be removed by surgery. Drugs used in chemotherapy, such as paclitaxel, carboplatin, doxorubicin, and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Bevacizumab may stop the growth of tumor cells by blocking blood flow to the tumor. Giving chemotherapy together with bevacizumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
