Quality of Life of Colorectal Cancer Screenees in the Period Between Colonoscopy and Next Clinic Visit for Final Report: Does Real-time Endoscopic Optical Diagnosis Improve Their Quality of Life

Colorectal cancer screening program has been proven to reduce colorectal cancer (CRC) mortality and is cost-effective. It has been adopted by most countries in the world, and colonoscopy is regarded as the most accurate test for detecting colorectal neoplasm. After screenees underwent colonoscopy, most endoscopists do not routinely explain the preliminary optical diagnosis to the subjects before they going home, which may cause unnecessary anxiety and may reduce the quality of life of the subjects before acquiring the final results. In recent years, endoscopic optical diagnostic technology has been validated by meta-analysis studies as an excellent tool to predict the histology of colorectal polyps and to differentiate the invasion depth of colorectal cancer. The real time feature of endoscopic optical diagnosis allows endoscopists to explain the preliminary results confidently to the subjects immediately after colonoscopy, which is expected to reduce the anxiety of the subjects before they acquired the final results and improve their quality of life. We designed a randomized controlled trial to validate whether real-time endoscopic optical diagnosis could decrease the anxiety burden and improve the quality of life for colorectal-cancer screenees after colonoscopy.

Standard of Care Alone or in Combination With Ad-CEA Vaccine and Avelumab in People With Previously Untreated Metastatic Colorectal Cancer QUILT-2.004

Background: Colorectal cancer is a common cancer in the U.S. It causes the second most cancer-related deaths. The drug avelumab and vaccine Ad-CEA together help the immune system fight cancer. Objective: To test if avelumab and Ad-CEA plus standard therapy treats colorectal cancer that has spread to other sites better than standard therapy alone. Eligibility: People ages 18 and older with untreated colorectal cancer that has spread in the body Design: Participants will be screened with: Test to see if their cancer has a certain deficiency Blood, urine, and heart tests Scans Medical history Physical exam Tumor sample. This can be from a previous procedure. A small group of participants will get Ad-CEA and avelumab plus standard therapy. This is FOLFOX plus bevacizumab for up to 24 weeks then capecitabine plus bevacizumab. The others will have treatment in 2-week cycles. They will be Arm A or B: Arm A: FOLFOX and bevacizumab by IV days 1 and 2 for 12 cycles. After that, capecitabine by mouth twice a day and bevacizumab by IV on day 1. Arm B: Ad-CEA injection every 2-12 weeks. Avelumab by IV on day 1 of each cycle. FOLFOX and bevacizumab by IV days 2 and 3 for 12 cycles. Then, capecitabine by mouth twice a day and bevacizumab through IV on day 2. Participants will repeat screening tests during the study. Participants will be treated until their disease gets worse or they have bad side effects. Arm A participants can join Arm B. They will have a visit 4 5 weeks after they stop therapy.

Combining Risk Factors and Faecal Immunochemical Testing in Colorectal Cancer Screening: a Randomized Controlled Trial

Colorectal Carcinoma (CRC) is the third most frequent diagnosed cancer worldwide, with 1.4 million new cases every year. In an attempt to reduce this number many countries have implemented a nationwide screening programme targeted at detecting CRC in an early phase using fecal immunochemical tests (FITs). People with an elevated level of blood in their stool are offered a colonoscopy, an invasive medical procedure where CRCs and premalignant lesions (together also referred to as advanced neoplasia) can be detected accurately. However, the current screening method using FIT is not optimal. In FIT-based CRC screening studies, 1 in 4 participants with CRC and 2 in 3 participants with advanced neoplasia receive a negative FIT result. In contrast, an estimated 1 in 2 FIT-positives have advanced neoplasia at colonoscopy. Recent studies have demonstrated that a risk model that takes into account the FIT result and other risk factors for CRC could enhance the effectiveness of a FIT-based CRC screening programme. The objective of this study is to assess the yield of advanced neoplasia in the colon and rectum of a FIT-based risk model at colonoscopy, compared to that of a FIT-only CRC screening strategy. Our hypothesis is that a risk-based model yields significantly more advanced neoplasia at colonoscopy than the FIT by itself, and that it does not affect participation rate. To assess this hypothesis, the investigators have designed a clinical trial in which the investigators randomize 23,000 asymptomatic individuals between the age of 55 and 75 years old to either risk-based screening (intervention group) or FIT-only screening (control group). The intervention group will receive a questionnaire on risk factors of CRC (e.g. smoking, family history of CRC), and a FIT. The control group will only receive the FIT. The positivity threshold of the FIT in both groups will be set at 15 micrograms haemoglobin per gram faeces. The positivity threshold of the risk-based model in the intervention group will be set at 0.10 (out of a range of 0 to 1), a threshold that is calculated with a goal to match the positivity rate of the control group. Participants with a result that is above the thresholds of the FIT and/or the risk-based model will be invited to undergo a colonoscopy according protocol of the Dutch national screening program. After the study has ended, the investigators will compare both groups to assess our hypotheses.
