Feasibility Study of a 4 Stage Bowel Obstruction Cancer Diet

Bowel obstruction is a common complication in patients with ovarian, peritoneal and bowel cancer due to a mass or spread of disease, causing narrowing to the gut, as these cancers can grow on the bowel surface. Certain foods may lead to symptoms such as pain, bloating, feeling full, feeling sick, vomiting and difficulty passing a bowel motion. There is limited evidence to establish the best diet to follow when someone is diagnosed with the risk of bowel obstruction and is experiencing symptoms after eating and drinking. The Dietitians at the Royal Surrey have developed a 4 stage bowel obstruction diet which they have been using with patients for 3 years. The 4 stages are clear fluids, all thin liquids, low fibre soft smooth diet, low fibre soft sloppy diet. Depending on the severity of symptoms and the risk of a blockage, patients are asked to follow a certain stage of the diet. They are advised to move up and down the stages as symptoms improve or get worse. This feasibility study aims to investigate if the diet can be used and is effective in clinical practice. The objectives are to see if this diet is easy to follow, can reduce symptoms of bowel obstruction, can improve quality of life, and reduce admissions to hospital because of bowel blockages. Patients at risk of bowel obstruction from colorectal or ovarian cancer are eligible to participate. They will remain in the study for a period of 4 weeks, during which time they will be asked to complete a diet diary and 3 questionnaires.

Diagnostic and Prognosis Value of Circulating DNA for CRC Patients' Surveillance After Curative Treatment

Inspite of curative treatment 30-50% patients with ColoRectal Cancer (CRC) develop tumor relapse during the first 3 years after treatment of the primary tumor. Treatment of relapses is based on surgical resection, when possible, chemotherapy and targeted therapies. To detect recurrences or metastases, a surveillance strategy is recommended for patients able to withstand complementary treatment during a five-year period. Over this period, the probability of one false-positive result is 87%. Considering that less than 10% of recurrent patients are suitable for potentially curative treatment and that more intensive programs enable an increase of the overall rate of curative resection but do not result in reduced mortality, less time and cost-consuming, tailored follow-up is necessary. The level of circulating ccfDNA, defined as extra cellular DNA, increases in CRC patients. The Inplex® method could validate the use of ccfDNA as a cancer biomarker in terms of prognosis and surveillance. Tubes for ccfDNA analysis will be taken during medical examination at the same time of the CEA dosage (if it was not made before the consultation). Cryotubes of plasma will be sent for analysis in the laboratory INSERM (National Health Institute) of Montpellier and the remaining plasma will be kept in biological collection. Patients will have a consultation of follow-up every 3-4 months during which the dosage of CEA and ccfDNA will be realized as well as a medical examination, a general examination (weight, size, and blood pressure), an evaluation of the indices of performance status and a nutritional evaluation in case of loss of weight.
