This association study of 377 Korean colorectal cancer patients examined 15 SNPs in 12 apoptosis-related genes as prognostic markers for survival after curative resection. RIPK1 rs2272990 (GA/AA genotype, HR=2.093, p=0.007) and CASP7 rs2227310 (GG genotype, HR=2.641, p=0.002) were significantly associated with worse disease-free survival in multivariate analysis, with similar associations for disease-specific survival. The polymorphisms showed stronger associations in colon cancer than rectal cancer.

In 90 DLBCL patients treated with R-CHOP chemotherapy, polymorphisms in apoptosis-related genes were analyzed. The AA genotype of LTA C804A (rs1041981) was associated with worse time to progression (HR = 7.92; 95% CI = 1.42-44.18; P = 0.018), as was the GG genotype of RIPK1 G83A (rs2272990) (HR = 20.02; 95% CI = 1.59-251.52; P = 0.018). These polymorphisms may serve as prognostic markers for DLBCL treated with R-CHOP.

A case-control association study of 240 early breast cancer patients examining 12 SNPs in apoptosis-related genes found that TNFSF10 rs1131532 (F275F) was significantly associated with poor survival outcomes, with the TT genotype showing worse disease-free survival (HR = 3.304, P = 0.002), distant disease-free survival (HR = 4.757, P = 0.001), and overall survival (HR = 4.691, P = 0.002). PTGS2 rs5275 was also associated with distant disease-free survival (HR = 0.302, P = 0.041).

This study analyzed 15 apoptosis-related gene polymorphisms in 76 patients with metastatic colorectal cancer treated with capecitabine and oxaliplatin chemotherapy. The PTGS2 8473T>C (rs5275) polymorphism was found to be significantly associated with progression-free survival (p=0.038, HR=2.19, dominant model p=0.046) and overall survival (p=0.040, dominant model p=0.013) in multivariate Cox regression analysis.
