Filter by:Previous OPTIMOX1 study investigated the use of oxaliplatin discontinuation and reintroduction in a novel stop-and-go strategy. Previously untreated patients were randomly assigned to either FOLFOX4 administered every 2 weeks until progression (arm A) or FOLFOX7 for 6 cycles, maintenance without oxaliplatin for 12 cycles, and reintroduction of FOLFOX7 for another 6 cycles (arm B). Data showed that there was no significant difference in median progression-free survival (PFS) and overall survival (OS) between two arms. Furthermore, this study showed lower Grade 3 neurotoxicity rate in arm B (17.9% vs 13.3%, P = 0.12).In order to investigate the efficacy and feasibility of the novel "Stop and go" strategy in Chinese mCRC patients, Prof. Shu Yongqian in JiangShu Province Hospital plans to conduct a randomized controlled study to compare continuous FOLFOX4 vs. FOLFOX4 in a Stop-and-Go Fashion in 1st Line mCRC patients. To avoid the high oxaliplatin dosage related neurotoxicity, FOLFOX4 regimen is chosen in this study.
RATIONALE: Drugs used in chemotherapy, such as S-1, 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. Giving S-1 together with bevacizumab may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving S-1 together with bevacizumab works as third-line therapy in treating patients with colorectal cancer that is recurrent or that cannot be removed by surgery.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of curcumin may prevent or treat colorectal cancer. PURPOSE: This phase I trial is studying the side effects of curcumin in preventing colorectal cancer in patients undergoing colorectal endoscopy or colorectal surgery.
RATIONALE: Drugs used in chemotherapy, such as capecitabine and irinotecan hydrochloride, 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 panitumumab, 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy, monoclonal antibody therapy, and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying the side effects of giving capecitabine and panitumumab together with radiation therapy with or without irinotecan hydrochloride and to see how well it works in treating patients undergoing surgery for localized rectal cancer.
The aims of this study are to: 1. explore supportive care needs in colorectal cancer patients with treatment and survivors; 2. compare the supportive care needs in different stage of colorectal cancer; 3. identify the significant factors for the supportive care needs; 4. explore the supportive care needs within one year after newly diagnosis.
Colorectal cancer (CRC) is the second leading cause of cancer in Puerto Rico (PR) accounting for approximately 1,500 individuals annually, which represent 12% of all cancer cases in the island. The genetic epidemiology of CRC among Hispanic populations is not well studied, hence studies focused on large, well defined ethnic groups such as Puerto Ricans, are clearly warranted. The first step towards evaluating the molecular, environmental, and genetic epidemiology of CRC in PR is to establish a population-based familial CRC registry. The following specific aims have been proposed: Specific Aim 1: To prospectively identify and recruit approximately 300 CRC probands from two distinct geographical areas in PR (Metropolitan and Southern Region). From each proband the investigators will obtain a pedigree extended to second-degree relatives and cousins. Assuming 10% will be positive for a family history of CRC, the investigators will then recruit all 30 probands with a family history of CRC and a sample of 15 family-history negative probands and obtain: paraffin-embedded tumors blocks, blood samples, risk factor and food frequency questionnaires. Specific Aim 2: To prospectively identify and recruit selected relatives (parents, grandparents, and same generation relatives - cousins and siblings) from the 45 probands identified in Specific Aim 1. In addition, for siblings and cousins of probands (i.e. relatives in the same generation as the proband), the investigators will obtain risk factor and food frequency questionnaires, and for colorectal cancer cases, tumor blocks and pathology reports of their cancers. Specific Aim 3: To estimate from this pilot study the following parameters: (a) response rate of probands and their selected relatives; (b) response rate of participants for each data item; (c) family history of CRC and other cancers; (d) number of living first- and second-degree relatives and cousins of probands; (e) number of these relatives who live in the same household and region/municipality; (f) prevalence/distribution of selected risk factors from the administered questionnaires.
RATIONALE: Studying samples of tissue, blood, urine, stool, and other biological fluids from patients with cancer and from healthy volunteers undergoing colonoscopy or endoscopy may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This research study is looking at gastrointestinal biomarkers in tissue and biological fluid samples from patients and participants undergoing colonoscopy, endoscopy, or surgery.
RATIONALE: Diagnostic procedures, such as radionuclide imaging using bispecific antibody, may help find colorectal cancer cells and learn the extent of disease. PURPOSE: This phase I trial is studying how well a bispecific antibody works in finding tumor cells in patients with colorectal cancer.
RATIONALE: Screening may help doctors find colorectal cancer sooner, when it may be easier to treat. Finding out what affects a patient's decision to undergo screening tests may help increase the number of patients who undergo regular screening for cancer. It is not yet known whether personalized invitations to undergo colorectal cancer screening are more effective than standard screening reminders. PURPOSE: This randomized phase III trial is studying ways to increase colorectal cancer screening in African Americans.
RATIONALE: Studying samples of blood in the laboratory from patients receiving oxaliplatin for cancer may help doctors learn more about changes that occur in DNA and identify biomarkers related to neurotoxicity. PURPOSE: This phase II trial is studying biomarkers in predicting neurotoxicity in patients with colorectal cancer receiving oxaliplatin.
