Filter by:In the proposed study, investigators will conduct a 90-day dietary intervention study in human subjects. Thirty individuals at risk for adenomatous colon polyp formation will be randomized to receive a calcium and multi-mineral-rich natural product (Aquamin) or a comparable level of calcium alone. There will also be a placebo group. Prior to ingesting the study agents and following the course of treatment, colonic biopsies will be obtained by sigmoidoscopy and quantitatively examined for markers of growth and differentiation. In this study, metabolomic and microbial profiles will also be generated from fecal and colon mucosal samples taken at baseline and study endpoint.
Oral curcumin (complex C3, Sabinsa Corp, Utah) will be given to patients with inoperable colorectal metastases who will be commencing standard care oxaliplatin-based (FOLFOX) chemotherapy for up to 12 cycles(approximately 6 months) of treatment. Primary measurements focus on safety and tolerability. These will be recorded in real-time and report the number and severity of adverse events. Secondary measurements will include efficacy, (measured by response rate with RECIST and overall survival in months) supported by biomarker analysis.
Laparoscopic (key-hole) large bowel resection is a minimally invasive procedure when compared to open large bowel resection, but is still associated with a significant amount of pain and discomfort. Analgesia is commonly provided by a multi-modal technique involving varying combinations of paracetamol, Non steroidal anti-inflammatory drugs (NSAIDs), regional analgesia and oral or parenteral opioids. While epidural analgesia is considered the gold standard for open colo-rectal procedures it can be associated with significant complications and may delay hospital discharge in laparoscopic procedures. Opioids are associated with an increased incidence of nausea, vomiting and sedation and reduced bowel motility which can also prolong recovery. Transversus Abdominis Plane (TAP) block is a technique which numbs the nerves carrying pain sensation from the abdominal wall and provides effective and safe analgesia with minimal systemic side effects. Their perceived benefits are thought to relate to reduced opioid consumption and therefore reduced opioid side effects. The investigators believe ultrasound guided TAP blocks will reduce pain and morphine consumption with a resultant improved patient satisfaction, earlier return of bowel function and earlier hospital discharge. The key research question the investigators are trying to answer is whether TAP block provide better pain relief than local anaesthetic infiltration of the laparoscopic port sites. Both techniques are currently being used in our hospital and a retrospective audit demonstrated better analgesia and lower consumption of morphine in the TAP block group.The differences were not statistically significant as the number patients in the audit were not large enough.The investigators are hoping that this study will demonstrate that the difference is real by recruiting the necessary number of patients into each group (36 per group)
Background: - The experimental cancer treatment drug AZD6244 has been shown to block signals that tell cancer cells to grow. Cetuximab, a drug approved to treat cancer of the head, neck, colon, and rectum, also blocks signals that tell cancer cells to grow. Researchers are investigating the highest safe dose of AZD6244 to give with cetuximab, and will also investigate the effectiveness of this drug combination in individuals who have colorectal cancer that involves a particular protein known as the K-RAS protein. Cetuximab is not used to treat colorectal cancer with K-RAS tumors because it has not been shown to be effective, but researchers believe that adding AZD6244 to cetuximab may improve how well cetuximab works, even in people with K-RAS tumors. Objectives: - To evaluate the safety and effectiveness of AZD6244 in combination with cetuximab for solid tumors that have not responded to standard treatment. - To evaluate the safety and effectiveness of AZD6244 in combination with cetuximab for colorectal cancer that involves the K-RAS protein and has not responded to standard treatment. Eligibility: - Individuals at least 18 years of age who have been diagnosed with solid tumors that have not responded to standard treatment. - Individuals at least 18 years of age who have been diagnosed with colorectal cancer that has not responded to standard treatment. Design: - This protocol will involve two separate studies: an initial study to establish the highest safe and effective dose of AZD6244 and cetuximab in individuals with solid tumors, and an expansion study of AZD6244 and cetuximab in individuals with colorectal cancer involving the K-RAS protein. - Participants will be screened with a full medical history and physical examination, blood samples, imaging studies, and other tests as required by the researchers. - AZD6244 is a capsule to be swallowed once or twice a day, every day, with water on an empty stomach. Cetuximab will be given intravenously once a week, over 2 hours for the first dose and over an hour for every following dose. This combination of daily AZD6244 and weekly cetuximab will be repeated in 28-day cycles of treatment. Participants will keep a diary to record the time of taking AZD6244 each day, as well as any side effects. - Participants will have frequent blood tests and other exams during the first cycle of treatment, up to five visits to the National Institutes of Health (NIH) and other visits to their local doctor to in the first 28-day cycle. - During subsequent cycles, participants will have four visits to NIH and four visits to your local doctor for examinations, blood tests, and imaging studies. - Participants may continue to receive the AZD6244 with cetuximab for up to 6 cycles, until the tumor grows, unacceptable side effects development, or the participant or participant's doctor decides to stop participation. There will be a final study visit that repeats the procedures performed during the screening visit....
The standard procedure for treating colonic cancer is changing from open surgery to laparoscopic surgery. Following open colonic surgery patients are fatigued and loss body mass and have a reduction in physical function, but the investigators do not know if this is also the case following laparoscopic surgery. This study examines how fatigue, quality of life, physical function, and body composition changes following laparoscopic colonic surgery. Patients are examined preoperatively and postoperative day 10 and 30.
Randomised doublet blinded study of the effect of tablet Magnesia (laxative) on post operative bowel ileus after open colonic resection. Material: 56 patients in two equal groups. Primary endpoint: Bowel function. Secondary endpoints: Intake of food and drinks.
- To determine the prevalence of colonic neoplasm in patients who had previously undergone screening colonoscopy - To determine the optimal time interval for re-screening in average risk individuals - To determine potential baseline characteristics that predicts adenoma recurrence
