Filter by:Approximately 20-30 % of colon cancer patients who have no metastasis in lymph nodes after definitive colectomy have recurrence with distant metastasis. These recurrences could be due to missed occult tumor cells or micrometastasis. Detailed examination of all lymph nodes is expensive and time consuming. Sentinel lymph node mapping using Indocyanine green dye helps in identifying the lymph nodes which are most likely to harbour metastasis. These sentinel lymph nodes can be subsequently subjected to detailed pathologic examination and immunohistochemistry which increases the likelihood of identifying micrometastasis and occult tumor cells. Patients found to harbour such metastasis can be treated with additional chemotherapy after surgery. The aim of the study is to examine the feasibility of sentinel lymph node mapping using Indocyanine green dye in colon cancer and evaluate the upstaging rate in post-operative colon cancer patients who don't have metastatic lymph nodes on routine histopathology.
AIM:To evaluate the effectiveness of a therapeutic exercise program (PET) in cancer patients in improving the quality of life and the need for supervision by health professionals during the performance of same after 6 weeks of intervention. DESIGN: Randomized and controlled clinical trial, parallel groups with active control group. With masking of randomization, patient evaluation and analysis of the data. SUBJETS OF STUDY: 58 patients diagnosed with breast and colon cancer and treated up to 2 years later, both with surgery, chemotherapy and hormonal treatments (inhibitors of aromatase, tamoxifen). INTERVENTION: both groups the treatment will be a common work-based therapeutic exercise program aerobic, strength-resistance and self-stretching, in addition to a reinforcement in recommendations usual self-care. The study includes two phases, phase of supervised work and phase of tracing. One of the groups will be supervised in the realization of PET for a period of 6weeks and the other group will do it autonomously and without supervision. The patients will be followed for 1 year, with five blind evaluations: at the beginning of the study, after 6 weeks of intervention, 3, 6 and 12 months after the start of the study.MEASUREMENTS: Principal: Quality of life assessed with the questionnaire measured with the European questionnaire Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30 (EORTC QLQ-30). Pre-post intervention measure, 3, 6 and 12 months. Secondary: Cancer-related fatigue evaluated with the Functional Assessment of scale Chronic Illness Therapy - Fatigue (FACIT-F). Pre-post Measurement intervention, 3, 6 and 12 months. Functional capacity measured with the Test 6 minutes walking test. Pre-post Measurement intervention, 3, 6 and 12 months. Valuation of the measured force with manual hydraulic dynamometer and 5- test repetition sit-to-stand. Pre-post intervention measure, 3, 6 and 12 months.COST: effectiveness and cost / incremental utility associated to the program wil be estimated.
clinical impact of LN ratio with Kras expression in colon cancer
It has been reported that Cryptosporidium parvum, a species of a protozoan frequently isolated from humans and animals, is able to induce digestive adenocarcinoma in a rodent model. Consistently, some epidemiological studies have reported an association with cryptosporidiosis in patients with colorectal adenocarcinoma. However, the correlation between cryptosporidiosis and human digestive cancer remains unclear at this time, and it is not known whether this intracellular parasite, considered an opportunistic agent, is able to induce gastrointestinal malignancies in humans. In order to add new arguments for a probable association between cryptosporidiosis and digestive human cancer, the main aim of this study is to determine prevalence and to identify species of Cryptosporidium among a French digestive cancer population.
VAPOR-C is a randomised study of the impact of IV versus inhaled anaesthesia (propofol versus sevoflurane) and lidocaine versus no lidocaine on duration of disease free survival inpatients with either colorectal or non small cell lung cancer.
Clinical studies have shown that patients with right-sided colon cancer have reduced progression-free and overall survival compared to patients with left-sided colon cancer. At the same time, patients with right-sided colon adenomas have a higher risk of developing interval cancers after endoscopic mucosal resection. Dysbiosis and known bacterial drivers play a significant role in the carcinogenesis of colorectal cancer, and may contribute to the growth of adenomas. Clinical studies have found biofilm formation and positive staining for Fusobacterium nucleatum (FN) in almost all right-sided colon cancers and adenomas. The composition of bacteria also in the normal mucosa in these two groups of patients has been found to be different from healthy controls. Endoscopic preoperative antibiotic local treatment of the biofilm and tumors would theoretically result in decreased tumor mass, recovery of the mucosa, and a normalization of the immune response in the treated section of the colon. The oral administration of the antibiotic metronidazole in mice has shown to lower the tumor load (FN-positive xenograft tumors) and decrease in intratumoral abundance of the pro-carcinogenic bacteria, FN. The aim of this study is to investigate the effect of local antibiotic treatment with fosfomycin and metronidazole on tumor characteristics and the colonic biofilm in patients with right-sided colon cancer or right-sided colon adenomas. This is a clinical proof-of-concept intervention study, and the investigators are to our knowledge the first group to look into local antibiotic treatment of biofilm in patients with colon cancer or colon adenoma. It is based on a non-randomized trial design with an open label single group assignment. There are two tracks depending on the pathology of the tumor: 1) patients with right-sided colon cancer; 2a) patients with right-sided colon adenoma. The intervention is a therapeutic endoscopy where the antibiotics fosfomycin and metronidazole are sprayed throughout the right colon section from caecum to the right colon flexure (100ml of gel contains 800mg of fosfomycin and 200mg of metronidazole). Patients will be included prospectively from the surgical department of Herlev University Hospital and Zealand University Hospital once having received oral and written information, followed by signing the consent. There will be a retrospective cohort of patients with colon adenoma from 2018 (track 2b). The investigators will retrieve the archived adenoma tissue as control tissue. In Clinical Trial, Track 1 and Track 2a will be registered as two different arms that use the same intervention, but the results from each arm later on is going to be reported in separate publications.
The success of the enhanced recovery program after surgery leads us to consider outpatient management of the colectomy. To this end, the investigators have designed an observational and prospective study of left laparoscopic colectomy on an outpatient basis. The objective is to assess the harmlessness of this management compared to standard management in the context of a public hospital.
- Benefit of adjuvant chemotherapy after curative surgery for stage II Colon Cancer is still debated. Several high-risk features may help to stratify stage II cancer patients into groups that will truly benefit from adjuvant chemotherapy. However, those factors are rather subjective, and no specific trial has been designed to answer the high-risk stage II colon cancer question directly. - Immunoscore® Colon, an in vitro diagnostic test, which quantifies the density of CD3+ and CD8+ T lymphocyte populations in the center the tumor (CT) and its invasive margin (IM) using immunohistochemistry and automated image analysis. Immunoscore® has been extensively validated as a prognostic biomarker in early stage CC patients. This unique diagnostic assay measuring host immune response at the tumor site may inform the decision to administer adjuvant chemotherapy in resected Stage II and III CC patients. - This randomized trial is studying how observation compares to adjuvant chemotherapy (investigator's choice) in stage II colon cancer patients with high-risk features and High-Immunoscore®. The trial would represent a unique opportunity to classify stage II CC patients based on their tumor microenvironment with the aim to provide efficient patient stratification to improve clinical care.
This phase II trial studies how well TAS-102 and oxaliplatin work in treating patients with stage IV colon cancer. Drugs used in chemotherapy, such as TAS-102 and oxaliplatin, 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.
