| Abstract: | BackgroundProgressive telomere shortening may be related to genomic instability and carcinogenesis. Prospective evidence relating telomere length (TL) with colorectal cancer (CRC) risk has been limited and inconsistent.MethodsWe examined the association between pre-diagnostic peripheral blood leukocyte TL and CRC risk in two matched case-control studies nested within the Nurses’ Health Study (NHS) and the Health Professionals Follow-Up Study (HPFS). Relative leukocyte TL was measured using qPCR among 356 incident CRC cases and 801 controls (NHS: 186/465, HPFS: 170/336).ResultsWe did not find a significant association between pre-diagnostic TL and CRC risk in all participants, multivariable-adjusted odds ratio (OR) (95% CI) for TL Quartile 1 (shortest) vs. Quartile 4 (longest) = 1.36 (0.85, 2.17), P-trend = 0.27; OR (95% CI) per 1 SD decrease in TL = 1.12 (0.92, 1.36)].ConclusionsOur prospective analysis did not support a significant association between pre-diagnostic leukocyte TL and CRC risk. |
