Abstract
Conclusion:
In this study, we used RT-PCR and IHC to analyze RRM1 and ERCC1 mRNA and protein expression in PDA specimens. PDA patients with low expression of RRM1 by IHC derived benefit from gemcitabine-based chemotherapy. Assessment of RRM1 mRNA expression was limited by the small sample size. Low ERCC1 expression by RT-PCR was associated with a 2.5 times higher risk of mortality than high expression (p=0.031). There was no association between ERCC1 expression by IHC and survival; however, agreement between mRNA and protein expression was poor for ERCC1. This study demonstrates the ERCC1 and RRM1 expression have an impact on the survival of PDA patients treated with gemcitabine.
