Filter by:The purpose of this study is to see if screening with flexible sigmoidoscopy (a flexible viewing tube) may reduce large bowel cancer and cancer deaths. The researchers also want to see if the addition of screening for occult blood in stools may contribute further to this aim. Additionally, the researchers also want to see to which extent (and in which direction) the study may influence overall endoscopic activity in the general population in the screening area and in areas where controlled screening is not established.
RATIONALE: Screening tests, such as colonoscopy and fecal occult blood test, may help doctors find tumor cells early and plan better treatment for colorectal cancer. PURPOSE: This randomized phase III trial is studying colonoscopy to see how well it works compared to fecal occult blood test in screening healthy participants for colorectal cancer.
RATIONALE: Drugs used in chemotherapy, such as irinotecan, leucovorin, and fluorouracil, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them after surgery may kill any remaining tumor cells. It is not yet known whether combination chemotherapy is more effective than observation alone in treating patients who have undergone surgery for colon cancer. PURPOSE: This randomized phase III trial is studying irinotecan and fluorouracil with or without leucovorin to see how well they work compared to observation alone in treating patients who have undergone surgery for stage II colon cancer.
RATIONALE: Drugs used in chemotherapy, such as fluorouracil, leucovorin, and irinotecan, use different ways to stop tumor cells from dividing so they stop growing or die. Giving more than one chemotherapy drug may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving fluorouracil together with leucovorin and irinotecan works in treating patients with recurrent or refractory metastatic unresectable colorectal cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy, such as capecitabine, use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy before surgery may shrink the tumor so that it can be removed. PURPOSE: This phase II trial is studying how well neoadjuvant radiation therapy and capecitabine work in treating patients who are undergoing surgery for stage III or stage IV colorectal adenocarcinoma.
RATIONALE: Drugs used in chemotherapy, such as leucovorin, fluorouracil, and oxaliplatin, use different ways to stop tumor cells from dividing so they stop growing or die. Celecoxib may stop the growth of colorectal cancer by stopping blood flow to the tumor and by blocking the enzymes necessary for tumor cell growth. Combining chemotherapy with celecoxib may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining celecoxib with leucovorin, fluorouracil, and oxaliplatin in treating patients who have metastatic colorectal cancer.
RATIONALE: A coloanal anastomosis may be effective in restoring bowel function after radiation therapy and surgery to remove the rectum. It is not yet known whether a J-pouch coloanal anastomosis is more effective than a side-to-end coloanal anastomosis in restoring bowel function in patients with rectal adenocarcinoma who have undergone radiation therapy and surgery to remove the rectum. PURPOSE: This randomized phase III trial is studying how well J-pouch coloanal anastomosis works compared to side-to-end coloanal anastomosis in treating patients with rectal adenocarcinoma who have undergone radiation therapy and surgery to remove the rectum.
The purpose of this study is to find the highest dose that can be given safely to people who have had liver disease resected. This is a Phase I study. The goal of a phase I study is to find a safe dose range based on side effects. The drugs that will be given by vein are OXALIPLATIN ("Oxali") plus 5-FLUOROURACIL and LEUCOVORIN ("5FU" and "LV"). This is systemic chemotherapy, since it goes to the whole body. The drugs that will be placed in the pump are FLOXURIDINE (FUDR) and DEXAMETHASONE. (The dexamethasone is not an anti-tumor drug; it helps protect healthy liver tissue from possible side effects of the FUDR.) This is the regional chemotherapy, since it goes only to the liver. The researchers have studied these drugs and know the best doses of each when they are used in patients who have not had liver resections. We do not yet know how the drugs work with each other in patients with a liver resection. This study will tell us the best doses of each drug when they are given over the same period of time.
RATIONALE: Drugs used in chemotherapy, such as capecitabine, fluorouracil, and oxaliplatin work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. PURPOSE: This randomized phase III trial is studying radiation therapy and either capecitabine or fluorouracil with or without oxaliplatin and comparing them to see how well they work when given before surgery in treating patients with resectable rectal cancer. It is not yet known whether radiation therapy and either capecitabine or fluorouracil is more effective with or without oxaliplatin in treating rectal cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known which schedule of chemotherapy is most effective in treating colon cancer. PURPOSE: Randomized phase III trial to compare different schedules of chemotherapy using carboplatin with fluorouracil and leucovorin in treating patients who have stage IIB or stage III colon cancer.
