This prospective observational study including consecutive patients with inflammatory bowel disease treated with either infliximab or adalimumab showed that although the correlation between the ELISA and the homogeneous mobility shift assay was good for both drugs, the agreement was poor.
Purpose
Innovations in genetic medicine have lead to improvements in the early detection, prevention, and treatment of cancer for patients with inherited risks of gastrointestinal cancer, particularly hereditary colorectal cancer and hereditary pancreatic cancer.
Methods
This review provides an update on recent data and key advances that have improved the identification, understanding, and management of patients with hereditary colorectal cancer and hereditary pancreatic cancer.
Findings
This review details recent and emerging data that highlight the developing landscape of genetics in hereditary colorectal and pancreatic cancer risk. A summary is provided of the current state-of-the-art practices for identifying, evaluating, and managing patients with suspected hereditary colorectal cancer and pancreatic cancer risk. The impact of next-generation sequencing technologies in the clinical diagnosis of hereditary gastrointestinal cancer and also in discovery efforts of novel genes linked to familial cancer risk are discussed. Emerging targeted therapies that may play a particularly important role in the treatment of patients with hereditary forms of colorectal cancer and pancreatic cancer are also reviewed. Current approaches for pancreatic cancer screening and the psychosocial impact of such procedures are also detailed.
Implications
Given the availability of novel diagnostic, risk-reducing, and therapeutic strategies that exist for patients with hereditary risk for colorectal or pancreatic cancer, it is imperative that clinicians be vigilant about evaluating patients for hereditary cancer syndromes. Continuing to advance genetics research in hereditary gastrointestinal cancers will allow for more progress to be made in personalized medicine and prevention.
In our clinical experience outside the context of a clinical trial, natalizumab is largely reserved for CD patients with extensive ileocolonic disease who have failed conventional immunosuppressants and of at least 2 anti-tumor necrosis factor agents. This drug is, however, well tolerated and offers significant clinical improvement for more than a year in one-third of these difficult-to-treat CD patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
