Background: Colorectal cancer is the second most common cancer in the world which is mainly caused by epigenetic and environmental factors. Among these epigenetic factors, gut microbiota is an important one. Although it has not been proved a unique group of bacteria correlated with colorectal cancer, these findings have generally demonstrated differences between healthy and disease gut microbio...

familial adenomatous polyposis (fap) is responsible for < 1% of colorectal cancer (crc) cases and is inherited as an autosomal dominant trait. patients generally present hundreds to thousands of adenomas and develop colorectal cancer by age 35- 40 if left untreated. here we report four patients with germline frameshift mutation (small deletion) at exon 15 of adenomatous polyposis coli (apc) tum...

BACKGROUND MUTYH-associated polyposis is a recessively inherited disorder characterized by a lifetime risk of colorectal cancer that is up to 100%. Because specific histological and molecular genetic features of MUTYH-associated polyposis colorectal cancers might influence tumor behavior and patient survival, we compared survival between patients with MUTYH-associated polyposis colorectal cance...

U pper urinary tract transitional cell carcinoma (UUTTCC) accounts for 5% of all urothelial carcinomas. Hereditary non-polyposis colorectal cancer (HNPCC) is an autosomal dominant syndrome predisposing to colorectal cancer that accounts for about 5% of all colorectal cancers. It is revealed by colorectal cancer (63%) or extracolonic cancers, most often of the endometrium (9%) or ovary, but some...

About 6% of colorectal cancers are caused by genetic mutations associated with hereditary colorectal cancer syndromes. The most common hereditary cancer syndromes nurses are likely to encounter include hereditary nonpolyposis colon cancer or Lynch syndrome, familial adenomatous polyposis, attenuated familial adenomatous polyposis, and MYH polyposis.
