Filter by: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.
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.
This study tries to evaluate the role of chemoradiation with capecitabine and bevacizumab in oligometastatic patients neither being progressive nor resectable after chemotherapy.
The primary objectives of this randomized clinical trial are to evaluate if perioperative SDD can reduce clinical anastomotic leakage rate and its septic consequences as well as other infectious complications. By reduction of septic complications long-term oncological outcome might simultaneously improve.
Primary Objective: Correlation of the skin and/or eye toxicity grade secondary to Cetuximab or Panitumumab and the SNP profile of the Epidermal Growth Factor Receptor (EGFR) domain III region. Secondary Objectives: Correlation of SNP profile with indicators of tumour response parameters, such as radiological response, duration of response, time to progression (TTP), overall survival (OS) time, incidence of non-dermatological adverse events.
To evaluate the Radial Reload Stapler during laparoscopic low anterior resection (LAR) or anterior proctosigmoidectomy for rectal cancer by assessing the primary and secondary endpoints.
The aim of colonoscopy is to visualize the inside of the entire large bowel. Several factors can make the procedure difficult, and sometimes a complete examination is not possible. Complicating factors include poor bowel preparation and technical challenges such as differences in anatomy (long, redundant colonic segments), post-surgical adhesions, strictures and diverticulosis. A special endoscope with two inflatable balloons, originally designed to examine the small bowel, has been used for several years with success in such technically difficult colonoscopies. More recently a modified double-balloon instrument was designed specifically for colonoscopy, but the documentation of the performance of this instrument is limited. The aim of the present study is to investigate the performance of the double-balloon colonoscope in cases where conventional colonoscopy have failed due to technical difficulties.
