Abstract:
PURPOSE: We evaluated DNA polymorphisms in genes related to DNA repair, cell-cycle control and tumour microenvironment to determine possible associations with response and survival in neoadjuvant-treated gastric cancer patients. PATIENTS AND METHODS: One hundred and seventy eight patients who received platinum/5FU-based chemotherapy were genotyped for 10 polymorphisms in nine genes (ERCC1: Asn118Asn, C>T; ERCC1: 8092C>A; TP53: Arg72Pro, GA; STK15: Phe31Ile, A>T; VEGF: 936C>T; TNF-alpha: -308G>A; interleukin-1b (IL-1B): -511C>T; IL-1 receptor antagonist (IL-1RN): variable tandem repeat; IL-8: -251T>A). Genotypes were correlated with histopathological and clinical response and overall (OS) and progression-free survival (PFS). RESULTS: Only the cyclinD1 genotypes were associated with clinical response ( [Formula: see text] ). Significantly worse survival rates were noted in patients homozygous for the G-allele as compared to patients with the AG or AA genotypes of the cyclinD1 polymorphism (OS: P(log-rank)=0.024; PFS: P(log-rank)=0.007) and in patients homozygous for the short allele compared to all other genotypes at the IL-1RN polymorphic locus (OS: P(log-rank)=0.026; PFS: P(log-rank)=0.013). The combination of both unfavourable genotypes demonstrated strong prognostic relevance (OS: P(log-rank)=0.006; PFS: P(log-rank)=0.001). Multivariate analysis for OS in the group of completely resected patients (n=139) revealed statistical significance for ypM (P<0.001), histopathological response (P<0.001) and the combined cyclinD1/IL-1RN genotypes (P=0.043). CONCLUSION: The cyclinD1 and IL-1RN polymorphisms were associated with survival. The combination of specific cyclinD1 and IL-1RN genotypes showed a particular prognostic relevance and should be considered an independent prognostic marker for neoadjuvant-treated gastric cancer patients.
