Filter by:To analyze the pathological tumor response on resected colorectal cancer metastases after preoperative treatment with cetuximab combined with FOLFOX or FOLFIRI regimen in a prospective cohort (RAS and B-RAF WT tumors) and to correlate this response with patient's outcome.
Background: - Some types of inflammation may increase the risk of cancers in the intestinal track. Because of this possibility, anti-inflammatory drugs may be able to prevent tumor growth and spread. One such drug, sulindac, may be helpful to study. Researchers want to see if people who are having surgery to remove intestinal tumors from advanced colorectal cancer will benefit from sulindac. It will be tested against a placebo. Objectives: - To see if sulindac can improve treatment outcomes in people who are having surgery for advanced colorectal cancer. Eligibility: - Individuals at least 18 years of age who are having surgery for advanced colorectal cancer. Design: - Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies and heart and lung function tests may also be given. - Participants will be separated into two groups. One group will take sulindac. The other will take a placebo. - Participants will take sulindac or placebo twice daily from about 2 to 3 weeks before the scheduled surgery. Seven days before the surgery, they will stop taking the pills. - Participants will have surgery to remove their tumors. The surgery will also remove affected organ tissue. - Participants will start to take the pills again once they have recovered from surgery. They will continue taking the sulindac or placebo twice a day for 3 years, or for as long as the tumors do not return.
The purpose of this study is to evaluate the efficacy of the implementation of an educational program on adherence to capecitabine alone or in combination to lapatinib.
The aim of this study is evaluate the feasibility of early two-stage hepatectomy in patients with liver metastasis from colorectal cancer.
The goal of this clinical research study is to learn more about the possible effects of metformin extended release (ER) in patients with colon cancer or adenomas who are about to have surgery. The safety of this drug will also be studied. Metformin-ER is commonly used to control blood sugar levels in patients with diabetes. It is also designed to block a protein in tumor cells that is important in tumor growth and blood vessel development. This may cause cell death or reduce the spread of the disease.
Hypothesis:The Adnab-9 antigen is a predictive biomarker in individuals at risk of developing colorectal neoplasia. Study aim is to evaluate the potential of the Adnab-9 monoclonal antibody (MAb) as a marker of cancer risk in a population at increased risk for colorectal cancer (CRC). This marker would be compared to other current and emerging diagnostic methods. 2,800 Veterans would be recruited into the study. In phase 1, candidates would be defined as having increased CRC risk by a short questionnaire. Stool samples would be obtained and a semi-quantitative Adnab-9 antigen assay (ELISA) would be determined. Patients with differing high and low estimations of fecal Adnab-9 would undergo colonoscopy at which time other samples of effluent and colonic mucosa would be taken, and a detailed lifestyle and nutritional questionnaire would be completed. The characteristics of the Adnab-9 fecal test as a diagnostic test would be critically determined using the outcome of the colonoscopic and other test results. The patients will be contacted through the mail and by word of mouth. Informed consent will be obtained before the samples are obtained. The participants are clinically defined as high-risk and therefore screening colonoscopy would be likely performed in any event. A number of assays for Adnab-9 are feasible including slot-blot, Western blot, and ELISA. Other stool studies include conventional fecal occult blood tests (FOBT or FIT) that will be performed in tandem. The investigators therefore began this method of collection and obtained consent from over 2000 patients with a similar overall compliance rate with FOBT screening procedures to that reported previously of approximately 50%. Currently the study is no longer enrolling patients at the Detroit VA and is now finalizing data entry. Another 450 patients to be recruited at the Philadelphia VAMC.
This is a prospective time-and-motion study to document and compare the time used in preparation, dispensing and administration for capecitabine/oxaliplatin (XELOX) versus IV 5-FU/leucovorin/oxaliplatin (FOLFOX4) regimens in colorectal cancer (CRC) patients.
The purpose of this study is to determine if the True Human Monoclonal antibody Xilonix (MABp1) can prolong the life of colorectal carcinoma patients that are refractory to standard therapy.
This randomized, open-label, multicenter study will evaluate the efficacy and safety of folinic acid (leucovorin), 5-fluorouracil (5-FU), oxaliplatin, and irinotecan (FOLFOXIRI) / bevacizumab regimens (concurrent and sequential) versus folinic acid (leucovorin), 5-fluorouracil, and oxaliplatin (FOLFOX) / bevacizumab in first-line in participants with metastatic colorectal cancer. Participants will be randomized to receive bevacizumab 5 milligrams per kilogram (mg/kg) intravenously every 2 weeks with either concurrent or sequential FOLFOXIRI or with FOLFOX for 4 to 6 months of induction therapy, followed by maintenance therapy with bevacizumab plus either leucovorin/5-fluorouracil or capecitabine until disease progression occurs. After disease progression, participants will receive treatment with a fluoropyrimidine-based chemotherapy plus bevacizumab.
This study tries to evaluate the role of chemoradiation with capecitabine and bevacizumab in oligometastatic patients neither being progressive nor resectable after chemotherapy.
