Overall Survival in Women with Breast Cancer: The Influence of Pepsinogen C Gene Polymorphism
2008
We aimed to study the role of an insertion/deletion polymorphism in the Pepsinogen C (PGC) gene in the clinical outcome of 172 breast cancer patients. The six polymorphic alleles were amplified using PCR. Our results indicate that patients carrying the allele 6 present a higher 5-year survival mean (83.4% of 6 allele carriers were alive at 5 years vs. only 68.6% of noncarriers, p=0.001), suggesting a role for this polymorphism in the outcome of breast cancer patients. We hypothesize that PGC polymorphism can be a predictive biomarker in breast cancer, contributing to an individual profile of great interest in clinical oncology.
