Active clinical trials for "Colonic Neoplasms"

Colorectal cancer is a major health concern in the Western world with an estimated lifetime risk of 5-6%. The goal of achieving effective cancer prevention is driven by the prediction that CRC will become the leading cause of death (surpassing heart disease) in this decade, with an estimated 1,000,000 new cases and over 500,000 deaths per year, worldwide. Despite continuing advances in diagnosis and therapy, long-term survival rates have not improved significantly over the last four decades. Nearly 50% of all CRC patients will die of the disease. Preventive strategies offer the best hope, at least until our understanding of the biology of cancer matures to the point where it can be implemented into therapy. The search for new chemopreventive compounds with minimal toxicity raises particular interest in phytochemicals.Curcumin (diferuloylmethane) is a natural compound derived from the rhizome of Curcuma Longa, an East Indian plant, commonly called turmeric. It has been shown to possess potent anti-inflammatory and anti-oxidative properties, for which it has a long history of dietary use as a food additive. Curcumin has also a potent anti-proliferative effects against a variety of cancer cell lines in vitro, which stem from its ability to modulate many intracellular signal transduction pathways. Human phase I-II studies found curcumin to be safe, and indicated no dose-limiting toxicity when taken by mouth at doses up to 10 g/day. This data, together with the dismal therapeutic options available for colon cancer patients, suggest that curcumin warrants investigation in this setting. The present study evaluates gemcitabine in combination with curcumin and celecoxib for patients with colon cancer.

This trial is to evaluate the safety and efficacy of using MASTER, a robotics enhanced endosurgical system to perform endoscopic submucosal dissection (ESD) of gastric/colon cancer in human.

Cancers of the colon and rectum are the third most common cancers in Canadian males and females. The initial therapy of colorectal cancer is surgery to remove the cancer and nearby lymph glands. If the cancer has spread to the lymph glands there is a high chance that the cancer will come back. To reduce the risk of the cancer recurring, patients are treated with an anticancer drug capecitabine. This study will determine if a simple blood test can predict which patients are at risk for developing side effects from this chemotherapy. In addition, participants of this study will be followed to determine if this same blood test will predict which patients will have their cancer relapse.

Objectives To investigate the impact of tele-supervised prehabilitation on functional capacity in frail colon cancer patients undergoing colorectal resection and to evaluate the effects of prehabilitation on muscle strength and endurance, quality of life (QoL), executive functions, fatigue and inflammatory and metabolic parameters. Methods A randomized controlled trial will be conducted. Patients will be randomised into either a prehabilitation group (PREHAB) or a control group. Prehabilitation group will participate in a 4-week telerehabilitation before surgery while the control group will receive usual care and World Health Organization recommendations on physical activity for health before surgery. Program exercise will consist of three moderate-intensity aerobic and resistance sessions per week. Subjects will have assessments at baseline, pre-intervention and 8 weeks after surgery. The primary outcome will be functional capacity measured by using the 6-min walk test. The secondary outcomes will be: physical measurements, QoL, level of physical activity, executive functions, fatigue, body composition, blood test, energy expenditure.

EMI-137 in laparoscopic colonic resections is a single-centre stage IIa developmental study. Ten adult participants with a diagnosis of colon adenocarcinoma undergoing laparoscopic colonic will be recruited to the trial. Participants will receive a single intravenous dose of the IMP - EMI-137 1 to 3 hours before surgery. The ability of EMI-137 to produce visible intra-operative fluorescence of primary colon cancer and lymph node metastases will be explored and evaluated.

To evaluate the efficacy and safety of neoadjuvant FOLFOXIRI chemotherapy (irinotecan, oxaliplatin and fluorouracil) in the patients with locally advanced colon cancer.

The purpose of this study is to assess the impact of more frequent follow-up (by videoconference) of these patients. Videoconference is a method of communication over a distance. In this method, the patient will hear the person's voice (like on the telephone) and will see that person over video. The study will compare more frequent follow-up of patients by videoconferencing to routine follow-up of patients. The investigators will compare each type of follow-up to see the effect on the number of times patients need to visit emergency rooms or need admission to hospitals. The study will also look at the difference between each type of follow-up on patients' quality of life and social support thirty days after hospital discharge. The study will also measure satisfaction and acceptability of this intervention among those who had follow-ups by videoconference.

In patients with locally advanced colon cancer (high risk stage II and stage III), curative surgery followed by adjuvant FOLFOX-4 chemotherapy has become the standard of care. However, for 30-40% of these patients, the current curative treatment strategy of surgical excision followed by adjuvant chemotherapy fails either to clear locoregional spread or to eradicate distant micrometastases, leading to disease recurrence. Preoperative chemotherapy is an attractive concept for locally advanced colon cancer and has the potential to impact upon both of these causes of failure. Optimum systemic therapy at the earliest possible opportunity may be more effective at eradicating distant metastases than the same treatment given after the delay and immunological stress of surgery. Added to this, shrinking the primary tumor before surgery may reduce the risk of incomplete surgical excision, and the risk of tumor cell shedding during surgery. ECKINOXE is a multicenter randomized phase II trial designed to evaluate efficacy (response rate) and feasibility (safety, tolerance) of these two chemotherapy regimens (FOLFOX-4 alone and FOLFOX-4+Cetuximab) in a neoadjuvant strategy in patients with locally advanced colon cancer. Control arm includes patients for whom standard treatment comprises surgery followed by adjuvant FOLFOX-4 chemotherapy. This phase II study will assess the feasibility of a neoadjuvant strategy in these patients and determine which neoadjuvant regimen is the most effective in terms of response rate.

We hypothesize through this randomized, prospective, single center adjuvant study, that cytokine-induced killer cell in patients with stage III colon cancer can improve survival in this patient population over control. Stage III colon cancer patients can benefit most from adjuvant chemotherapy, but the 5 year survival rate is still around 60%. We wish CIK cell therapy can improve the survival rate of stage III colon cancer patients.

It has been reported that the immune status of patients with cancer were suppressed, especially those after surgery and adjuvant chemotherapy. Thus, immunotherapy may decrease the recurrence rate after surgery. CIK cells transfusion has been reported as an effect therapy in advanced cancers. In another retrospective study, investigators found that adjuvant CIK therapy would prolong the disease-free survival (DFS) for colorectal cancer patients. The purpose of this study is to determine wether adjuvant immunotherapy with CIK cells in patients with colon cancer after operation will prolong DFS, and overall survival (OS).
