Active clinical trials for "Colonic Neoplasms"

The GEPOC study investigates the effect of comprehensive geriatric assessment and intervention for frail older patients (65 years or older) undergoing elective surgery for colorectal cancer. the geriatric intervention will be pre- and postoperative. included in the intervention is an exercise intervention. The main aim of the study us to see if the functional decline in this group can be reduced.

This study is a phase Ib prospective, open label study evaluating the effect of vaccination on the immune microenvironment of cancers with results compared to banked tissue from historical controls. Prospectively vaccinated patients will also serve as their own controls by comparing the immune microenvironment of the tumor in pre-treatment biopsies to post-treatment surgical specimens. This is also a dose-escalation study with consecutive enrollment and advancement of cohorts in an overlapping fashion.

The study of circulating tumoral DNA makes it possible to study, without invasive procedures or pathological studies, the tumoral DNA circulating in the blood of a patient and its various alterations. In patients with colon-rectal cancer with resected tumor, circulating tumor DNA can be used as a predictive biomarker of metastatic relapse of cancer. However, the routine extension of circulating tumoral DNA remains limited due to several difficulties. One of the pifalls that circulating tumor DNA is greatly diluted by healthy circulating DNA from non-tumor cells. The amount of healthy circulating DNA has been described as being influenced by certain physiological parameters. The aim of the study is to increase knowledge on the influence of physiological factors associated with sports activity and meal on the release kinetics of circulating DNA.

Background. Enhanced Recovery After Surgery (E.R.A.S.) programs are now widely accepted in colonic laparoscopic resections because of faster recovery and less perioperative complications. Objective. Aim of this study is to assess safety and feasibility of discharging patients operated on by laparoscopic colectomy on Post Operative Day 2 (POD 2), so long as the first flatus has passed and in the absence of complication-related symptoms. Design & Settings. Non-inferiority, open-label, single center, prospective, randomized study comparing "Ultra" to Classic E.R.A.S. with discharge on POD 2 and 4 respectively. Patients. 765 patients with resectable non metastatic colonic cancer were analyzed: 384 patients were assigned to "Ultra" E.R.A.S. and 381 to Classic E.R.A.S. Main Outcome Measures. Demographics, clinico-pathological, ASA class and morbi-mortality, along with surgical complications, re-operation and readmission rate were recorded and compared. Primary end-point was mortality; secondary end-points were morbidity, re-admission and re-operation rate. Limitations. It is a single center experience; it is not double-blind, with the intrinsic risk of intentional or unconscious bias; exclusion criteria because of "non compliance" may be considered arbitrary.

This is a multicenter, open-label, phase I study of rSIFN-co (3 times a week via subcutaneous injection for 21 days, with 1 week of washout per cycle).

Colon cancer is one of the most common cancers in France with more than 36,000 new cases per year. Despite significant advances in therapeutic care, the prognosis of colon cancers with metastases remains bad. The treatment of metastatic disease is based on chemotherapy coupled with therapeutic antibodies. The most commonly used are anti-EGFR (Epidermal Growth Factor Receptor), which allowed a significant increase in patient survival. They are responsible for skin toxicity in the form of an acneiform rash which can be debilitating for patients and require discontinuation of treatment. However, this toxicity is strongly correlated with treatment efficacy. Understanding the mechanisms of cutaneous side effects of anti-EGFR is therefore a major challenge to treat and better understand the association with treatment efficacy. The objective of this study is to investigate a link between cutaneous inflammatory response in patients treated with anti-EGFR, serum level of anti-EGFR and treatment efficacy. It will be conducted systematic consultations dermatology, skin biopsies and blood samples in patients treated with anti-EGFR. From biopsies, it will be searched by an infiltration of inflammatory cells and expression of genes involved in skin inflammation.

This is a pilot study to evaluate the safety of a vaccine that consists of an alphavirus replicon (VRP) encoding the protein (CEA) that has been found to be associated with cancers such as colon cancer in patients that have stage III colon cancer. We will also evaluate the patient immune response to the vaccine.

Colorectal cancer is the second most common cancer in the world and the second leading cause of cancer-related mortality. Colorectal cancers arise from precursor adenomatous polyps in a well characterized adenoma to carcinoma progression. The removal of such precursor lesions reduces colorectal cancer mortality between 30 to 50%. Colonoscopy is used for detection of neoplastic polyps but significant miss rates of such lesions are reported. Methods to reduce spasm of the colon have been investigated to increase adenoma detection rates including the use of warm water irrigation and hyoscine butyl bromide. Carbon dioxide warmed to body temperature is postulated to have spasmolytic effects. Administration of warmed carbon dioxide during colonoscopy may improve polyp detection. Objective: In this study, colonoscopy using warmed carbon dioxide insufflation will be compared to standard room temperature air insufflation to see if there is a greater detection of polyps per patient. Methods: Patients undergoing colonoscopy for screening and surveillance indications will be included and randomized to receive either room temperature room air or warmed carbon dioxide (37 degrees Celsius). Endoscopists and patients will be blinded to the intervention. Data on indication, preparation, sedation, withdrawal time will be recorded. Polyp detection rate will be the primary outcome. Secondary outcomes will include adenoma detection rate and advanced lesion detection rates.

This pilot phase I trial studies the side effects and best dose of CPI-613 when given together with fluorouracil in treating patients with colorectal cancer that has spread to other parts of the body and cannot be removed by surgery. CPI-613 may kill tumor cells by turning off their mitochondria. Mitochondria are used by tumor cells to produce energy and are the building blocks needed to make more tumor cells. By shutting off these mitochondria, CPI-613 deprives the tumor cells of energy and other supplies that they need to survive and grow in the body. Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving CPI-613 with fluorouracil may kill more tumor cells.

This phase I trial is studying the side effects and the best dose of MEK Inhibitor AZD6244 when given together with cetuximab in patients with advanced or refractory solid tumors that cannot be removed by surgery. MEK inhibitor AZD6244 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving MEK Inhibitor AZD6244 together with cetuximab may kill more tumor cells.
