BACKGROUND Gastric polyps, such as adenomas and hyperplastic polyps, can be found in various colonic polyposis syndromes. Unlike in sporadic gastric adenomas, in which the increased risk of colorectal neoplasia has been well characterized, information in sporadic gastric hyperplastic polyps was limited. AIM To evaluate the association of sporadic gastric hyperplastic polyps with synchronous c...
BACKGROUND/AIMS Gallbladder polyps and colorectal adenomas share many common risk factors; however, their association has never been studied. The aim of this study was to investigate this association in asymptomatic healthy subjects. METHODS Consecutive asymptomatic subjects who underwent both screening colonoscopy and abdominal ultrasonography at Kyung Hee University Hospital in Gang Dong be...
BACKGROUND Some authors have studied the relationship between the presence of polyps, adenomas and cancers of upper gastrointestinal tract (stomach and duodenum) and risk of colorectal polyps and neoplasms; however, the results are controversial, which may be due to study sample size, populations, design, clinical features, and so on. No meta-analysis, which can be generalized to a larger popul...
BACKGROUND AND AIMS Colorectal adenomas are recognised as precursors of colorectal carcinomas. The significance of hyperplastic (metaplastic) colorectal polyps is unknown. The relationship between hyperplastic polyps and adenomas, and the prevalence and incidence of these lesions were evaluated in individuals predisposed to familial colorectal cancer. METHODS A total of 299 individuals partic...
ABSTRACT Colorectal cancer remains a leading cause of morbidity and mortality worldwide. Most colorectal cancers begin as a growth of tissue called a polyp, some types of which can change into cancer over the course of several years. Angiogenesis, the formation of new blood vessels, is known to play a key role in the initiation, growth and...
colorectal cancer is the most common gastrointestinal cancer and the second leading cause of cancer deaths worldwide. the purpose of this study is to investigate the prevalence of epstein-barr virus in patients with colorectal carcinomas and polyps in comparison with healthy people. in this analytical case-control study, 15 patients with colorectal cancer and 20 patients with colorectal polyp ...
Background & Aim: Colorectal polyps are among the commonest lesions encountered by surgical pathologist. In the United States, colonoscopy and flexible sigmoidoscopy are recommended for almost all people over the age of 40 years. The development of carcinoma from adenomatous lesions is referred to as the adenoma-carcinoma sequence. Virtually, all colorectal carcinomas exhibit genetic altera...
Juvenile (retention) polyps are usually solitary lesions in the colorectum but may be multiple in juvenile polyposis. The association between juvenile polyps and colorectal neoplasia is controversial. We present three patients with juvenile polyposis who had colorectal adenomas or adenomatous epithelium in juvenile polyps at ages 3, 4, and 7 years. In a retrospective study of 57 additional pati...
BACKGROUND AND AIMS Colorectal cancer (CRC) is associated with a significantly reduced survival rate in transplant recipients. The prevalence and risk factors of CRC and of colorectal polyps after orthotopic liver transplant (OLT) remain unclear. The study aim was to determine the prevalence of colorectal polyps in OLT recipients. A secondary objective was to explore possible risk factors of p...
Purpose. To investigate the prevalence and risk factors of hyperplastic and adenomatous colorectal polyps in a Taiwanese general population. Methods. From January 2009 to December 2011, consecutive asymptomatic subjects undergoing a routine health check-up were evaluated by colonoscopy. The colorectal polyps were assessed, and medical history and demographic data were obtained from each patient...
