BACKGROUND Considerable disparities exist in colorectal cancer (CRC) incidence and mortality rates between blacks and whites in the United States. We estimated how much of these disparities could be explained by differences in CRC screening and stage-specific relative CRC survival. METHODS We used the MISCAN-Colon microsimulation model to estimate CRC incidence and mortality rates in blacks, ...

Sporadic colorectal cancer (CRC) is classified into several molecular subtypes. We previously established two groups of DNA methylation markers through genome-wide DNA methylation analysis to classify CRC into distinct subgroups: high-, intermediate-, and low-methylation epigenotypes (HME, IME, and LME, respectively). HME CRC, also called CpG island methylator phenotype (CIMP)-high CRC, shows m...

We consider the “and” communication device that receives inputs from two players and outputs the public signal yes if both messages are yes, and outputs no otherwise. We prove that no correlation can securely be implemented using this device, even when infinitely many stages of communication are allowed. ∗THEMA, Université Paris X-Nanterre, 200 avenue de la République, 92001 Nanterre, France an...

The aberrant expression of long noncoding RNAs (lncRNAs) is implicated in cancer development and progression. However, the clinical significance and mechanism by which NONHSAT062994 regulates colorectal cancer (CRC) is unknown. We here reported that NONHSAT062994 was significantly downregulated in human CRC tissues and cell lines. Moreover, its expression was inversely correlated with tumor siz...

Background: Chinese and Korean Americans have lower colorectal cancer (CRC) screening rates than other racial/ ethnic groups, which may be explained by a low level of CRC knowledge and a high level of misconceptions. This study explores the role of knowledge in CRC screening among these groups. Methods: Chinese (N=59) and Korean (N=61) Americans older than 50 were recruited from the Washington ...

BACKGROUND Inflammatory bowel disease (IBD; including ulcerative colitis and Crohn's disease) is associated with an increased risk for colorectal cancer (CRC). Chronic mucosal inflammation is a key factor in the onset of carcinogenesis in IBD patients. Although most gene alterations that cause sporadic CRCs also occur in patients with IBD-associated CRC, some gene sequences and mutation frequen...

PURPOSE/OBJECTIVES To examine sociocultural factors that influence an informed decision about colorectal cancer (CRC) screening among African American men and women. DESIGN Descriptive, cross-sectional. SETTING A medical center, a National Cancer Institute-designated comprehensive cancer center, and various social organizations and barbershops in a midwestern city of the United States. SA...

background of the study: colorectal cancer (crc) which is the third most diagnosed cancer throughout the world is steadily rising in the asian countries with the incidence rates mimicking the western counterparts. the pre-neoplastic nature of the transitional mucosa (tm) adjoining crc lacks conclusive evidence so far. pertaining to this, the study of the mucus layer, the functional component of...
