Ontology highlight
ABSTRACT: 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.
Project description:RATIONALE: Drugs used in chemotherapy, such as irinotecan, 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. Giving more than one drug (combination chemotherapy) may kill more tumor cells.
PURPOSE: This phase I trial is studying the side effects and best dose of irinotecan when given together with fluorouracil and leucovorin in treating patients with advanced gastrointestinal cancer.
Project description:RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving the drugs in different combinations may kill more tumor cells.
PURPOSE: Phase II trial to compare the effectiveness of either irinotecan or fluorouracil plus leucovorin in treating patients who have metastatic colorectal cancer that has been previously treated with oxaliplatin with or without irinotecan.
Project description:RATIONALE: Drugs used in chemotherapy, such as liposome-encapsulated irinotecan hydrochloride PEP02, irinotecan hydrochloride, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving liposome-encapsulated irinotecan hydrochloride PEP02 together with leucovorin calcium and fluorouracil is more effective than giving irinotecan hydrochloride together with leucovorin calcium and fluorouracil as second-line therapy in treating patients with metastatic colorectal cancer.
PURPOSE: This randomized phase II trial is studying liposome-encapsulated irinotecan hydrochloride PEP02 given together with leucovorin calcium and fluorouracil to see how well it works compared with giving irinotecan hydrochloride together with leucovorin calcium and fluorouracil as second-line therapy in treating patients with metastatic colorectal cancer.
Project description:RATIONALE: Drugs used in chemotherapy use 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 more tumor cells.
PURPOSE: Randomized phase III trial to compare the effectiveness of fluorouracil and leucovorin with or without irinotecan in treating patients who have undergone surgery for stage III colorectal cancer.
Project description:In patients with advanced colorectal cancer, leucovorin, fluorouracil, and irinotecan (FOLFIRI) is considered as one of the reference first-line treatments. However, only about half of treated patients respond to this regimen, and there is no clinically useful marker that predicts response. A major clinical challenge is to identify the subset of patients who could benefit from this chemotherapy. We aimed to identify a gene expression profile in primary colon cancer tissue that could predict chemotherapy response. Patients and Methods:- Tumor colon samples from 21 patients with advanced colorectal cancer were analyzed for gene expression profiling using Human Genome GeneChip arrays U133. At the end of the first-line treatment, the best observed response, according to WHO criteria, was used to define the responders and nonresponders. Discriminatory genes were first selected by the significance analysis of microarrays algorithm and the area under the receiver operating characteristic curve. A predictor classifier was then constructed using support vector machines. Finally, leave-one-out cross validation was used to estimate the performance and the accuracy of the output class prediction rule. Results:- We determined a set of 14 predictor genes of response to FOLFIRI. Nine of nine responders (100% specificity) and 11 of 12 nonresponders (92% sensitivity) were classified correctly, for an overall accuracy of 95%. Conclusion:- After validation in an independent cohort of patients, our gene signature could be used as a decision tool to assist oncologists in selecting colorectal cancer patients who could benefit from FOLFIRI chemotherapy, both in the adjuvant and the first-line metastatic setting.
Project description:Panobinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving panobinostat together with fluorouracil and leucovorin calcium may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and the best dose of giving panobinostat, fluorouracil, and leucovorin calcium together in treating patients with stage IV colorectal cancer who did not respond to previous fluorouracil-based chemotherapy.
Project description: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.
Project description: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 whether fluorouracil and leucovorin plus irinotecan is more effective than fluorouracil and leucovorin alone for colorectal cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of fluorouracil and leucovorin with or without irinotecan in treating patients who have metastatic colorectal cancer.
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. Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It may also help the chemotherapy drugs work better by making tumor cells more sensitive to the drugs. Giving bortezomib with fluorouracil, leucovorin, and oxaliplatin may kill more tumor cells.
PURPOSE: This phase I trial is studying the side effects and best dose of bortezomib when given with fluorouracil, leucovorin, and oxaliplatin in treating patients with advanced or metastatic colorectal cancer.
Project description:RATIONALE: Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Leucovorin may help fluorouracil kill more tumor cells. Biological therapies, such as levamisole, may interfere with the growth of tumor cells and slow the growth of solid tumors. It is not yet known whether fluorouracil is more effective when given together with leucovorin and/or levamisole after surgery in treating colon cancer.
PURPOSE: This randomized phase III trial is studying giving fluorouracil together with leucovorin to see how well it works compared with giving fluorouracil together with levamisole, or giving fluorouracil together with leucovorin and levamisole after surgery in treating patients with Dukes’ B or Dukes’ C colon cancer.
