from june 1989, to june 1991, 58 patients with gi polyps were reviewed. except two patients who had multiple polyps, 56 had only one polyp. the size of polyps were 0.5 to 3 em in diameter. 51 (75%) of polyps were located in the rectosigmoid region, 25 (37%) were in the rectum and 26 (38%) in the sigmoid. (seventeen) (25%) polyps (two in right colon, four in transverse, and 11 in descending colo...

Colorectal cancer originates from the colon and rectum in the body. It is a very common type of cancer in the United States. The molecular pathogenesis of colorectal cancer involves complex pathways. There are different types of colonic polyps associated with colorectal cancer; mostly are precancerous in nature. In this article, different pathological mechanisms, colonic polyps, symptoms, diagn...

BACKGROUND The prevalence of colorectal polyps and adenomas in the general population of Mexico is unknown. AIM To determine the prevalence and risk factors for colorectal polyps detected during flexible sigmoidoscopy (FSIG) in asymptomatic patients. MATERIAL AND METHODS From 1995 to 2008, FSIG was performed as part of a complete check-up in patients who had lived in northeast Mexico for ov...

CONTEXT The I1307K mutation of the APC gene is found in approximately 6% of the Ashkenazi Jewish population and is associated with elevated risk of colorectal cancer. The incidence of the mutation in patients with colorectal adenomas is unknown. OBJECTIVES To determine the carrier rate of the I1307K mutation in Ashkenazi Jewish patients with a history of colorectal polyps but without colorect...

BACKGROUND Colorectal polyps (CP) are common among individuals older than 50 years. Some polyp types can precede colorectal cancer (CRC). This study aimed at describing histopathological characteristics of colorectal polyps in relation to age and gender among symptomatic patients referred for a colonoscopy examination during 2011-2014 in Tirana, Albania. METHODS Study population included 267 ...

INTRODUCTION Colorectal carcinoma (CC) may begin as benign polyps, which may be classified in different histological types with a different risk to develop cancer. Matrix metalloproteases (MMPs) are able to degrade all components in the extracellular matrix and are important tissue-remodeling enzymes and key elements in tumor invasion and metastasis. The aim of this study was to investigate the...

BACKGROUND AND AIMS Management of patients with endoscopically removed colorectal polyps is generally dependent on pathological evaluation. The aim of this study was to assess the accuracy and clinical impact of pathologic interpretation of colorectal polyps by community pathologists. METHODS Two expert gastrointestinal pathologists reviewed the slides of 300 colorectal polyps initially exami...

BACKGROUND Colorectal serrated polyp is considered as histologically heterogeneous lesions with malignant potential in western countries. However, few Asian studies have investigated the comprehensive clinical features of serrated polyps in symptomatic populations. The aim of the study was to evaluate the features of colorectal serrated polyps in a Chinese symptomatic population. METHODS Data...

Colorectal carcinoma ranks third in frequency among all cancers. With regards to cancer related mortality, colorectal carcinoma is known as the second cause (Levin et al., 2003). This condition accounts for 10% of all cancer related mortalities in women and men. Overall, lifetime risk for the development of colorectal carcinoma is still 5%. (Eddy, 1990) The wellknown risk factors are age, inher...

cer mortality in Taiwan, with more than 4,500 people dying of this disease in 2009. Malignant colorectal polyps represent the majority of early colorectal cancers. The term “malignant polyp” refers to a macroscopically benign appearing adenoma in which the invasive carcinoma is detected after histologic examination of the resected specimen. The muscularis mucosa must be breached to be defined a...
