Background:
The treatment of lung cancer has reached a therapeutic plateau. Several mechanisms of platinum resistance have been described, including the removal of platinum-DNA adduct by nucleotide excision repair (NER). Polymorphisms within the Xeroderma pigmentosum Group D protein (XPD), a member of the NER pathway, are associated with alterations in enzyme activity and may change sensitivity to platinum-based chemotherapy. The authors investigated the relation between XPD polymorphisms and treatment response, toxicity, and overall survival in patients who received platinum-based chemotherapy for advanced nonsmall cell lung cancer (NSCLC).
Methods:
Between 2001 and 2002, 108 patients with chemotherapy-naive, advanced NSCLC were recruited. Associations between XPD312/751 polymorphisms and XPD haplotype and treatment response, toxicity. and survival were evaluated.
Results:
Significant correlations were observed between XPD haplotype and Grade 4 neutropenia and overall survival together with a greater response to platinum-based chemotherapy for the XPD *A haplotype.
Conclusions:
The XPD haplotype may represent a useful pharmacogenomic marker of platinum-based chemotherapy in patients with advanced NSCLC and requires prospective validation.
