These results are in line with a multiethnic meta-analysis conducted with 9926 cases in 10 studies of various types of cancer (prostate, lung, head and neck, colorectal, skin, and glioma), which reveals that the TT/TC genotypes for the VDR BsmI (rs1544410) polymorphism were associated with worse OS (HR = 1.40; 95% CI = 1.05–1.75; I2 = 0.85) [46]. The gene discussed is VDR; the disease is glioma.
