Filter by:We hypothesize through this randomized, placebo-controlled adjuvant study, that Aspirin in patients with dukes C or high risk dukes B colorectal cancer (ASCOLT) can improve survival in this patient population over placebo control. If indeed found to be beneficial, because aspirin is cheap and easy to administer, it will positively impact the lives of many individuals in Asia and globally. STUDY OBJECTIVE To assess the effectiveness of Aspirin against placebo control in patients with dukes C or high risk dukes B colorectal cancer in terms of Disease Free Survival (DFS) and Overall Survival (OS) Primary endpoints - DFS among all eligible subjects (high risk Dukes B colon cancer, Dukes C colon cancer and rectal cancer patient sub-groups); - DFS among patients with colon cancer (high-risk Dukes B and Dukes C colon cancer). Secondary endpoints - Overall survival (OS) over 5 years - DFS and OS in - Chinese, Malay, Indian and other ethnic groups - Resected high risk Dukes B colon cancer, Dukes C colon cancer and rectal cancer sub-groups, individually - Compliant versus non-compliant subjects - PIK3CA mutated tumors (where samples are available)
RATIONALE: Pyridoxine (vitamin B6) may prevent or lessen hand-foot syndrome caused by chemotherapy. It is not yet known whether pyridoxine is more effective than a placebo in preventing hand-foot syndrome. PURPOSE: This phase III randomized trial is studying pyridoxine to see how well it works compared to a placebo in preventing hand-foot syndrome in patients who are receiving capecitabine for advanced colorectal cancer or breast cancer.
This study is being done to determine whether a telephone-based counseling intervention can help survivors of breast and colorectal cancer increase their weekly physical activity. Observational evidence suggests that physical activity after breast and colorectal cancer diagnosis decreases recurrence rates. Unfortunately, many people become less active during cancer therapy, and a substantial proportion never return to pre-diagnosis levels of physical activity. This study looks to see if people who have recently finished chemotherapy for breast, colon or rectal cancer can be motivated to increase their exercise by talking to an exercise specialist over the phone. The study also looks at changes in mood, fatigue, fitness, fat distribution and weight.
Introduction: S-1 is promising drug which could replace 5-fluorouracil plus l-leucovorin (5-FU/l-LV) in treatment of advanced colorectal cancer. Phase I/II study of S-1 plus Oxaliplatin (SOX) demonstrated its promising activity with acceptable toxicity as first-line chemotherapy in patients with untreated metastatic colorectal cancer and S-1 showed equivalent possibility to 5-FU/l-LV. On the other hand, phase I/II study of S-1 plus oral Leucovorin (S-1/LV) demonstrated that this regimen had enhanced efficacy in comparison with S-1 alone. From these results, it was expected that S-1/LV plus Oxaliplatin (SOL) would be more effective than SOX. Therefore, phase I/II study of SOL combination therapy was planned. Purpose A dose-finding study of S-1/LV plus Oxaliplatin (SOL) was planned to determine the recommended dose (RD), and to assess the response rate (RR) in patients with untreated metastatic colorectal cancer. The primary endpoints of the phase I portion are determination of the RD of SOL, and safety. The phase II portion of this study was aimed to assess the RR of SOL.
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, 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. Monoclonal antibodies, such as bevacizumab and 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 combination chemotherapy together with monoclonal antibody therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with monoclonal antibody therapy works in treating patients with advanced colorectal cancer with liver metastases or lung metastases that are potentially removable by surgery.
This study is an open-label, single center, and a dose-escalating phase I study to determine the maximal tolerated dose and the recommended dose of S-1 combined with irinotecan/oxaliplatin in patients with unresectable or metastatic colorectal or gastric carcinoma.
RATIONALE: Hepatic arterial infusion uses a catheter to carry tumor-killing substances directly into the liver. 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 floxuridine and dexamethasone directly into the arteries around the tumor together with combination chemotherapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well hepatic arterial infusion with floxuridine and dexamethasone works when given together with combination chemotherapy in treating patients with colorectal cancer that has spread to the liver.
Colorectal cancer is a type of cancer that begins in the large intestine (colon) or the rectum (end of the colon). Several drugs are often given in combination to treat colorectal cancer. One of the most active treatment combinations is known as FOLFOX, which is a combination of 5-fluorouracil (5-FU), leucovorin, and oxaliplatin. Oxaliplatin is a type of platinum drug and was approved by the FDA in 2004. While generally well-tolerated, oxaliplatin may cause toxicity to the nerves, such as sensory loss or cold sensitivity. Picoplatin is a new type of platinum drug that has shown activity with 5-FU in pre-clinical studies and has undergone extensive Phase 1 and Phase 2 testing in a variety of cancers. No significant nerve toxicity has been seen in previous studies of picoplatin. This study will review the safety and effectiveness of FOLPI, which is the combination of 5-FU and leucovorin with picoplatin in participants with colorectal cancer.
RATIONALE: Studying samples of blood and tumor tissue in the laboratory from patients with cancer may help doctors learn more about changes that occur in DNA and help doctors understand how patients respond to treatment. PURPOSE: This clinical trial is examining genes that affect disease outcome in patients with metastatic colorectal cancer.
RATIONALE: Monoclonal antibodies, such as cetuximab and 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 tumor cells by blocking blood flow to the tumor.Drugs used in chemotherapy, such as leucovorin, oxaliplatin, 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 cetuximab together with combination chemotherapy and bevacizumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery. PURPOSE: This randomized phase II trial is studying the side effects and how well giving cetuximab together with leucovorin, oxaliplatin, and fluorouracil works with or without bevacizumab in treating patients with resectable liver metastases from colorectal cancer.
