This case-control association study analyzed 10 telomere-length-associated SNPs in relation to pancreatic cancer risk in 2,374 cases and 4,326 controls from the PANDoRA consortium. The strongest association was with TERT-rs2736100 (OR=1.54, p=1.54×10⁻¹⁰), and a novel protective association was found with NAF1-rs7675998 (OR=0.80, p=1.87×10⁻⁶). A genetic telomere length score (teloscore) combining these variants reached genome-wide significance for PDAC risk (p=2.98×10⁻⁹ for highest vs. lowest quintile).

This study analyzes 243 rectal cancer patients to determine if colorectal cancer (CRC) susceptibility SNPs are associated with rectal cancer prognosis. SNPs on 8q24 (rs6983267 near MYC), 18q21 (rs12953717, rs4464148 in SMAD7), and 20q13 (rs4925386 in LAMA5) are found to be associated with disease-free survival and overall survival in rectal cancer patients, with some alleles associated with better or worse prognosis despite their effects on CRC risk.

This case-control study in Japanese population evaluated CRC risk prediction models using SNPs identified in European and East Asian GWAS. An 11-SNP model combining 6 European-identified SNPs (rs6983267, rs4779584, rs4444235, rs9929218, rs10936599, rs16969681) with 5 East Asian-identified SNPs (rs704017, rs11196172, rs10774214, rs647161, rs2423279) showed significantly improved discrimination capacity compared to a 6-SNP model alone (derivation AUC 0.6392 vs 0.6125, P=0.0039; replication AUC 0.5695 vs 0.5310, P=0.0018), with cumulative risk at age 80 estimated at 13% in high-risk versus 6% in low-risk genetic groups.

Mendelian randomization study of 16 genetic variants in 10 telomere-related loci using summary data from 420,081 cancer cases and 1,093,105 controls. Genetically increased telomere length was associated with higher cancer risk (glioma OR 5.27 [3.15-8.81], lung adenocarcinoma 3.19 [2.40-4.22], neuroblastoma 2.98 [1.92-4.62]) but reduced risk for cardiovascular diseases and some immune conditions.
