The long-term goal of our PIC is to develop effective strategies that can be applied clinically at the point-of-care to prevent, intercept, or detect PDAC at an early stage, thereby reducing PDAC burden and saving lives.

Cycling in Preventing Colorectal Cancer in Participants With Lynch Syndrome

High-Frequency Microsatellite InstabilityMismatch Repair Gene Mutation2 more

This trial studies how well cycling works in preventing colorectal cancer in participants with Lynch syndrome. Exercise such as cycling may reduce colorectal cancer risk in participants with Lynch syndrome.

Lynch Syndrome

Colorectal cancer (CRC) is the second cause of cancer-related death in western countries. CRC prevention and screening are major public health issues. Better knowledge of colorectal carcinogenesis could lead to better prevention. Gut microbiota (GM) is a complex community of bacteria, fungi, protozoa, viruses and bacteriophages which live in a symbiotic and epigenetic relationship with the host. GM can promote either digestive health or CRC through inflammatory and proliferative effects. Lynch syndrome (LS) is the most common familial CRC syndrome with a lifetime CRC risk of 52% in women and 69% in men. The risk of CRC depends upon type of altered mismatch-repair gene and environmental factors (diet, exercise, obesity, tobacco and alcohol intake, etc.). Regular surveillance including annual or biannual colonoscopy is recommended in LS patients. Chemoprevention has the potential to represent a cost-effective intervention in these high-risk patients and could allow a delay in colonoscopy surveillance. Regular low dose aspirin use is associated with a 20 to 30% reduction in the risk of sporadic colonic adenomas and CRC. The real benefit of aspirin is still to be consolidated. AAS-Lynch trial is an ongoing prospective multicenter (n=37), double-blind, placebo-controlled, randomized clinical trial, designed to investigate whether daily aspirin, at a dose of 100 or 300 mg compared with placebo, would decrease the occurrence or recurrence of colorectal adenomas in LS patients. The primary endpoint is the number of patients with at least one adenoma detected by chromo-endoscopy 48 months after initial colon clearance. At randomization and at the end of study, stool collection, blood collection, quality of life questionnaire, validated food frequency questionnaire (SU-VI-MAX2) and physical activity questionnaire are performed. The ongoing AAS-Lynch study allow accessing to a unique fecal collection in very well characterized LS patients including a comprehensive dietary evaluation at high risk for colorectal neoplasia and planned colonoscopy surveillance during a 48 months follow-up, exposed or not exposed to chronic low dose aspirin. The expertise of the scientific consortium with state of the art microbiota analysis, the comprehensive collection of data and the prospective design of the study will allow the evaluation of the true role of gut microbiota in CRC carcinogenesis.

Universal Screening for Lynch Syndrome in Women With Endometrial and Non-Serous Ovarian Cancer

Lynch SyndromeEndometrial Neoplasms2 more

This study will maximize identification of women with Lynch Syndrome using an enhanced screening strategy to identify those at risk. These women will be referred to genetic counselling for testing and those found to have Lynch Syndrome will be asked to invite first degree relatives to participate and undergo genetic testing for Lynch Syndrome. Screening guidelines and risk reducing surgery options for participants found to have Lynch Syndrome will be reinforced by the study and adherence to these guidelines will be assessed annually for ten years following Lynch Syndrome diagnosis to assess the impact and cost-effectiveness of this enhanced screening approach.

Energy Balance Interventions in Increasing Physical Activity in Breast Cancer Gene Positive Patients,...

Body Mass Index 25 or GreaterBRCA1 Gene Mutation9 more

This pilot clinical trial studies different types of energy balance interventions to see how well they work in increasing the physical activity levels of breast cancer gene-positive patients, Lynch syndrome-positive patients, chronic lymphocytic leukemia (CLL) survivors or family members of cancer survivors who are at high risk for cancer. Increasing exercise and eating healthy foods may help reduce the risk of cancer. Studying how well different types of interventions work in motivating cancer survivors or high-risk family members to increase exercise and healthy food choices may help doctors plan the most effective motivational program for cancer prevention.

Liquid Biopsy Evaluation and Repository Development at Princess Margaret

CancerBreast Cancer16 more

The objective of this protocol is to develop an institution-wide liquid biopsy protocol that will establish a common process for collecting blood and corresponding archived tumor specimens for future research studies at the University Health Network's Princess Margaret Cancer Centre. Circulating cell-free nucleic acids (cfNA), including cell-free DNA (cfDNA) and cell-free RNA (cfRNA), are non-invasive, real-time biomarkers that can provide diagnostic and prognostic information before cancer diagnosis, during cancer treatment, and at disease progression. Cancer research scientists and clinicians at the Princess Margaret are interested in incorporating the collection of peripheral blood samples ("liquid biopsies") into research protocols as a means of non-invasively assessing tumor progression and response to treatment at multiple time points during a patient's course of disease.

Hereditary Breast CarcinomaHereditary Ovarian Carcinoma1 more

This trial studies how well weight management and health behavior intervention works in helping patients with hereditary breast and ovarian cancer and Lynch syndrome mutation carriers lose or maintain a healthy weight and lower their risk for cancer. Lifestyle behaviors such as physical activity, diet, and weight management may play a key role in preventing cancers and improving outcomes even in those with hereditary cancer syndromes.
