Height and Colorectal and Endometrial Cancer Risk for Persons with Lynch Syndrome.

Height and Colorectal and Endometrial Cancer Risk for Persons with Lynch Syndrome. Am J Epidemiol. 2020 Aug 17;: Authors: Brouwer JGM, Newcomb PA, Bisseling TM, Figueiredo JC, Hopper JL, Jenkins MA, Koornstra JJ, Lindor NM, Vasen HFA, Win AK, Kampman E, van Duijnhoven FJB Abstract Persons with Lynch syndrome (LS - carrying a pathogenic mutation in a DNA mismatch repair gene) have an increased colorectal cancer (CRC) and endometrial cancer (EC) risk. A high reported variability in cancer risk suggests the existence of factors that modify cancer risk for LS. We aimed to investigate the association between height and CRC and EC for persons with LS using two large studies. Information of 1,213 men and 1,636 women with LS from the Colon Cancer Family Registry (1998-2007) and the GEOLynch cohort study (2006-2017) was harmonized. We used weighted Cox proportional hazard regression models with age on the time-axis to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for each 5 cm increment in self-reported height. CRC was diagnosed in 947 persons during 65,369 person-years of observation and 171 women were diagnosed with EC during 39,227 person-years of observation. Height was not associated with CRC for men (HR 1.00 per 5 cm, 95%CI: 0.91, 1.11) or women (HR 1.01 per 5 cm, 95%CI: 0.92, 1.11). Nor was height associated with EC (HR 1.08 per 5 cm, 95%CI: 0.94, 1.24). Hence, we observed no evidence for an association of heig...
