Active clinical trials for "Colorectal Neoplasms"

Lymph node involvement remains the main criteria for postoperative chemotherapy in patients with colon cancer (CC) without distant metastasis. To date, the prognostic value of the somatic quantitative molecular alterations such as loss or gain of genomic region is not established in CC. AIMS & METHODS: Using the one-step screening method based on the Quantitative Multiplex PCR of Short fluorescent Fragments (QMPSF), we aimed to assess the prognostic role of the simultaneous detection of main quantitative somatic alterations in stage II-III CC. Patients and Methods. We enrolled and collected all baseline characteristics of patients operated for a stage II-III CC with storage frozen tissues. The QMPSF was based on a simultaneous amplification of 9 selected target genomic sequences from literature: DCC (18q21); EGFR (7p12); P53 (17p13.1); BLK (8p23-p22); c-myc (8q24.12); APC (5q22.2); ERBB2 (17q12); STK6 (20q13.31); NR21 (14p11.1) and two control: DCOHM (5q31.1); HMBS (11q23.3). Comparison of each amplicon electropherograms obtained from tumour vs normal peritumoral tissue allowed us to identified gain or loss genomic region. The primary end-point was the local and/or distant recurrence and relation between clinical and single or combined molecular alterations and recurrence were evaluated.

This is a largest cohort study aimed to estimate the overall survival of patients been treated with regorafenib for metastatic colorectal cancer (mCRC) within the frame of a french compassionate program.

The purpose of this study is to compare the additional diagnostic yield obtained by using the acetic acid as vital substance to improve the detection of serrated lesions at colonoscopy. Patients who are scheduled for screening, surveillance or diagnostic colonoscopy will be recruited to the study and randomized to one of two groups. Each enrolled subject will undergo two "back-to-back" procedures limited to the examination of the right colon. Subjects in Group A (study group) will undergo a standard colonoscopy. Once the right colon has been fully examined, acetic acid 2% will be sprayed and the right colon re-examined from cecum to hepatic flexure with within a frame-time of two minutes. Subjects in Group B (control group) will undergo a second examination of the right colon without acid acetic and within the same frame-time. Results from the two groups will be analyzed and compared, with primary outcome measures being detection rates for serrated lesions. Secondary outcome measures will include adenoma detection rate in the right colon or other locations, characteristics of polyps detected, including size and histological results. Subjects will be followed through a 24-72 hour telephone interview for analysis of unexpected adverse events. Clinical results will be analyzed using various statistical measures of significance.

Hypothesis 1. When compared to passive dissemination, active dissemination will result in greater participant enrollment. Hypothesis 2. The intervention will be offered with equal fidelity in churches, clinics and community sites. Hypothesis 3. Knowledge of CRC screening and perceived risk of CRC will be positively correlated.

Background: - Early detection of colon cancer can improve the chances of successful treatment for most people. This approach is especially important if blood is detected in the stool. However, much better stool sample tests are needed to find this cancer early. To improve the tests, researchers want to collect samples from people who are already being screened for colon cancer. This study will collect information and samples from older adults in Shanghai, China. These adults will be participating in screening tests for colon cancer. Objectives: - To collect samples and medical information for colon cancer screening from older adults in Shanghai, China. Eligibility: Adults between 50 and 74 years of age who are being screened for colon cancer. Participants will be recruited from two community health centers in Shanghai, China. Design: Participants will provide information on their medical history and factors related to colon cancer. They will respond to questions on use of medications, diet choices (such as eating red meat), bowel habits, and other factors. Participants will collect samples for study. These samples will be collected within 3 days of the screening visit. Particpants will provide a urine sample and four stool samples. They will also use cotton swabs to collect samples from just inside the anus. The samples will be returned to the study doctors for research tests that may indicate who has colon cancer. Treatment will not be provided as part of this study.

The morbidity of colorectal cancer(CRC) is 10%～15% in China.mFolfox6 has become one of the standard regimes for metastatic colorectal cancer (mCRC). Neutropenia and oxaliplatin-induced neurotoxicity are the most common adverse effects which even result in discontinue of chemotherapy, especially for patients suffered from heavily acute neurotoxicity. Monosialotetrahexosylganglioside is a component of membrane of nerve cells. Previous phase II clinical trial showed, it can reduce oxaliplatin-induced neurotoxicity(OIN). But it did not certificated by phase III trial. Investigators designed the phase III trial to investigate the effect and safety of monosialotetrahexosylganglioside Sodium Injection for prevention OIN at colorectal cancer.

It is hypothesized that a progressive simulated learning strategy will result in better global clinical performance (e.g., technical, communication) and transfer of endoscopic skill, as compared with a high-fidelity simulation strategy.

Study of Oxidative stress Markers (F2 Isoprostanes for lipid peroxidation, Carbonyl groups for protein peroxidation, 3 Nitrotyrosine for damage by nitrogens, and 8-Hydroxyguanosine for RNA peroxidation)in patients with colorectal cancer undergo surgical treatment (preoperatively during the intervention and postoperatively) and controls.

The application of transarterial chemoembolisation (TACE) using LifePearl Microspheres loaded with Irinotecan in liver-only or liver-dominant metastatic disease in patients with colorectal adenocarcinoma will be observed. The registry has the following objectives: map the exact indications that the device is being used for and at which stage in treatment it is being applied to assess observed treatment outcomes in terms of safety and effectiveness as well as trying to determine any predictive response factors
