Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Studying samples of blood and tissue in the laboratory from patients with cancer, patients with colorectal polyps and from patients without polyps may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at biomarkers in blood and tissue samples from patients with colorectal cancer or colorectal polyps and from patients without polyps (healthy volunteers).

The purpose of this study is to examine the correlation between UGT1A1 genotypes and the efficacy of CPT-11 based regimens (FOLFIRI, CPT-11+S-1, CPT-11) for patients with metastatic colorectal cancer.

RATIONALE: Use of a web-based risk assessment tool may help improve screening rates for colorectal cancer. PURPOSE: This randomized clinical trial is studying personal electronic health records to see how well they work in improving screening rates for colorectal cancer.

This study will compare patient adherence to different colorectal cancer (CRC) screening tests to identify the most cost-effective strategy to decrease mortality from CRC. We hypothesize that different types of tests will have different adherence rates, that these rates will alter the cost-effectiveness analysis, and that we can identify patient variables associated with non-adherence to specific CRC screening strategies.

The purpose of this study is to determine whether direct mailings to patients with positive fecal occult blood tests can increase rates of performing followup colonoscopy.

The purpose of this study is to evaluate the effect of primary tumor resection on the metabolic activity of metastases in patients with a colorectal primary tumor and synchronous liver metastases by positron emission tomography (PET) with 2-deoxy-2-fluoro[18F]-D-glucose (FDG-PET) scanning.

RATIONALE: Genetic studies may help in understanding the genetic processes that cause some types of cancer. PURPOSE: Genetic trial to study certain genes of patients who have stage II or stage III colon cancer.

It is important for patients treated with anti-EGFR therapies to get access to cosmetic options to preserve their skin condition during treatment. Anti-EGFR therapies are known to fragilize epidermis and to provoke rashes; which often lead to treatment discontinuation. The aim of this study is to demonstrate that the Onco-Rash cream is able to preserve skin condition without side effects. Decreasing skin toxicity is expected to improve patients' life and facilitate treatment follow-up.

This is a prospective study addressing the challenge of predicting disease progression and/or recurrence in patients diagnosed with metastatic colorectal, pancreatobiliary, or esophagogastric cancer that are receiving anti-cancer therapy.

to determine screening value of stool-based SDC2 DNA methylation test for advanced colorectal neoplasia in the asymptomatic Chinese community population.
