    Abstract:
    A total of 42 polymorphisms have been identified in the TP53 gene. The polymorphic site of p53 at codon 72 in exon 4 and p53PIN3, a 16 bp insertion/duplication in intron 3, are the most studied. We tested p53PIN3 and the combined effect of the p53 codon72 and PIN3 polymorphisms on prognosis in 101 NSCLC cases. This study provides support for the prognostic effects of the multi-variant alleles from p53 exon 4 and intron 3, resulting in a significantly poorer prognosis in NSCLC. This approach highlights the value of examining multiple polymorphisms in genes to improve survival estimates.
