Active clinical trials for "Colorectal Neoplasms"

Advanced colorectal cancer (ACRC) is a heterogeneous disease and classification of patients is nowadays inefficient. Roughly twenty per cent of patients present with favorable figures (less than 4 liver nodules and less than 5 cm) and are suitable for local treatments (surgery or local-ablative therapies). Additionally, 10-15% of patients have poor performance status (PS >2) or are severe disabled due to geriatric syndromes or/and co-morbid diseases that preclude any treatment strategies than best supportive care alone. The rest of patients (fit patients not suitable for radical treatments) constitute the population of patients treated with palliative therapies. Despite of it not all these patients have the same prognosis. Patients with PS 0,1 and levels of LDH <ULN (Intermediate-risk patients) have better PFS and OS irrespective of therapy in all randomized clinical trials (de Gramont et al, JCO 2000; Douillard et al, Lancet 2000; Koopman et al, 2007). CRYSTAL trial shows a benefit in PFS (1.5 months) in RASWT of FOLFIRI plus cetuximab compared with FOLFIRI alone. Nowadays the selection of patients for cetuximab treatment is based on mutational status of KRAS, which allow to select those patients who will not respond to therapy. Other surrogate markers of activity should be also evaluated. Our hypothesis is that the suggested biomarkers will allow the selection of the patients who will benefit the most from the biweekly cetuximab treatment.

This study is being done to select an appropriate TF2 bsMAb dose suitable for pretargeting the 111In/90Y-labeled hapten-peptide (IMP-288). Eligible patients will receive a fixed dose of 90Y-IMP-288 4 days after the TF2 antibody injection. Two different dose levels of TF2 will be studied in the first part. Once an appropriate TF2 dose is selected based on information learned from the first 2 dose levels, patients will be enrolled onto several different increasing dose levels of 90Y-IMP-288.

RATIONALE: Diagnostic procedures, such as fludeoxyglucose F 18-PET imaging, may be effective in detecting residual disease after radiofrequency ablation of liver metastases in patients with colorectal cancer. PURPOSE: This clinical trial is studying fludeoxyglucose F 18-PET imaging to see how well it works for early detection of residual disease in patients undergoing radiofrequency ablation of liver metastases from colorectal cancer.

The objective of this study is to compare the effectiveness of multimedia and print tools designed to provide patients at safety-net clinics with comprehensible information about colorectal cancer screening and motivate them to complete screening.The print and multimedia interventions were constructed with parallel content to allow valid comparison of format-related effects on knowledge and screening rates.These easy to use tools will provide under served patients at community health centers with clear and consistent messages about colorectal Cancer(CRC) and CRC screening, delivered immediately before the patients see a doctor. Specific Aims To determine if multimedia and print interventions that provide patients with information and motivational messages about CRC screening increase screening rates above usual care. Determine whether showing patients a multimedia program achieves higher CRC screening rates than does a print booklet with equivalent messages. Examine if the effects of these multimedia and print interventions on CRC screening rates differ with literacy level. Examine if the effects of these multimedia and print interventions on CRC screening differ with race/ethnicity Examine if these multimedia and print interventions have differential effects on knowledge relevant to CRC screening.

The Third Eye® Retroscope® is a device that can be inserted through the instrument channel of a standard colonoscope to provide an additional, retrograde (or backward) view that reveals areas behind folds and flexures in the colon, and might detect additional polyps that cannot be seen with the colonoscope alone. Patients who participate as subjects in the study will undergo two complete colonoscopy procedures, a standard colonoscopy and a colonoscopy in which a Third Eye Retroscope is used along with the same colonoscope. Half of the patients will have the standard colonoscopy first followed by the Third Eye colonoscopy, and the other half will have the Third Eye procedure first. Results from the two groups will be analyzed and compared to determine the effectiveness of the Third Eye Retroscope for detecting additional adenomas and other polyps compared with the standard colonoscope alone.

This large randomized controlled trial is testing the effectiveness of automated telephone outreach with speech recognition to improve rates of screening for colorectal cancer. The hypothesis is that the intervention improves rates of screening overall and specifically rates of colonoscopy.

The study investigators have developed an interactive multimedia computer program that provides personally tailored education about colorectal cancer screening in the user's preferred language (English or Spanish). In this study, the investigators will examine whether use of the computer program increases the number of Hispanic patients who receive colorectal cancer screening and lessens or eliminates the glaring disparity in screening between Hispanics and non-Hispanic whites.

This single arm study will assess the efficacy and safety of a combination of modified FOLFIRI (irinotecan, 5-FU and leucovirin), Avastin and cetuximab in patients with previously untreated metastatic colorectal cancer. Patients will receive modified FOLFIRI (irinotecan 180mg/m2 iv, leucovirin 200mg/m2 iv, and 5-FU 400mg/m2 iv) on day 1 of each 2 week cycle, in combination with Avastin (5mg/kg iv on day 1 of each cycle) and cetuximab (loading dose of 400mg/m2 followed by 250mg/m2 on day 3 of each cycle). The anticipated time on study treatment is until disease progression or unacceptable toxicity, and the target sample size is <100 individuals.

RATIONALE: An interactive computer program may be more effective than a brochure in increasing colorectal cancer screening among African Americans. PURPOSE: This randomized clinical trial is studying an interactive computer program to see how well it works compared with a brochure in increasing colorectal cancer screening among African Americans.

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of celecoxib may keep polyps and colorectal cancer from forming in patients with familial adenomatous polyposis. PURPOSE: This randomized phase I trial is studying the side effects and best dose of celecoxib in treating young patients with a genetic predisposition for familial adenomatous polyposis.
