An atlas of the nonpolypoid colorectal neoplasms in inflammatory bowel disease.
The role of endoscopy in the management of patients with inflammatory bowel disease (IBD) is well established. However, recent data have shown significant limitations in the effectiveness of colonoscopy in preventing colorectal cancer (CRC) in patients with IBD colitis. The current standard random biopsy seemed largely ineffective in detecting nonpolypoid colorectal neoplasms. Data using chromo...
متن کاملPrevalence of nonpolypoid (flat and depressed) colorectal neoplasms in asymptomatic and symptomatic adults.
CONTEXT Colorectal cancer is the second leading cause of cancer death in the United States. Prevention has focused on the detection and removal of polypoid neoplasms. Data are limited on the significance of nonpolypoid colorectal neoplasms (NP-CRNs). OBJECTIVES To determine the prevalence of NP-CRNs in a veterans hospital population and to characterize their association with colorectal cancer...
متن کاملArtificial Intelligence for Artificial Artificial Intelligence
Crowdsourcing platforms such as Amazon Mechanical Turk have become popular for a wide variety of human intelligence tasks; however, quality control continues to be a significant challenge. Recently, we propose TURKONTROL, a theoretical model based on POMDPs to optimize iterative, crowdsourced workflows. However, they neither describe how to learn the model parameters, nor show its effectiveness...
متن کاملEndoscopic management of nonpolypoid colorectal lesions in colonic IBD.
Much of the flat or biopsy-only detected dysplasia in inflammatory bowel disease (IBD) that had historically warranted a colectomy can now be shown to be circumscribed lesions with dye-spray or advanced endoscopic imaging. These lesions are therefore amenable to endoscopic excision with close endoscopic follow-up, though are technically very challenging. This review discusses preresection asses...
متن کاملThe Immune Landscapes of Polypoid and Nonpolypoid Precancerous Colorectal Lesions
Little is known about the immunoediting process in precancerous lesions. We explored this aspect of benign colorectal adenomas with a descriptive analysis of the immune pathways and immune cells whose regulation is linked to the morphology and size of these lesions. Two series of polypoid and nonpolypoid colorectal adenomas were used in this study: 1) 84 samples (42 lesions, each with matched s...
