Dietary Fiber Intake And Risks Of Proximal And Distal Colon Cancers

The pubmed database was searched to identify relevant cohort studies published from inception to august 2016 in order to examine individually the association between dietary fiber intake and the risk of proximal colon cancer pcc and that between dietary fiber intake and the risk of distal colon cancer dcc.
Dietary fiber intake and risks of proximal and distal colon cancers. A random effects model was used to compute summary risk estimates. Within the colon no strong evidence of a difference in association between cancers located in the distal and proximal regions emerged from our results p for heterogeneity 0 72. Dietary fiber intake and risks of proximal and distal colon cancers.
Epidemiological studies have suggested that intake of dietary fiber is associated with decreased risk of colon cancer however these findings are inconsistent in that dietary fiber intake is differentially associated with risks of proximal colon and distal colon cancers. The purpose of this study was to conduct a systematic review and meta analysis of studies investigating the relationship between dietary fiber intake and subsite specific colon cancer the pubmed database was searched to identify relevant cohort studies published from inception to august 2016 in order to examine individually the association between dietary fiber intake and the risk of proximal. Order to examine individually the association between dietary fiber intake and the risk of proximal colon cancer pcc and that between dietary fiber intake and the risk of distal colon cancer dcc.
However in categorical models an inverse trend was observed for cancer located in the distal region of the colon but not for proximal colon cancer.
