ABSTRACT
PURPOSE:
The excision repair cross-complementation group 1 (ERCC1) status was assessed in patients receiving carboplatin and gemcitabine for inoperable non-small-cell lung cancer (NSCLC). We analyzed the association between the ERCC1 status and the overall survival after the chemotherapy. PATIENTS ANDMETHODS:
We retrospectively identified 163 patients with inoperable NSCLC and sufficient tumor tissue for ERCC1 analysis, who had received carboplatin and gemcitabine as first-line treatment. Immunohistochemistry was used to assess the expression of ERCC1.RESULTS:
One hundred sixty-three patients were included. Seventy (42%) were ERCC1 positive. Patients treated with carboplatin and gemcitabine and having ERCC1-negative tumors had a significantly increased survival when compared to patients with ERCC1-positive tumors (median survival, 12.0 months v 8.2 months; P = .02). This difference was mainly seen in men, where those with ERCC1-negative tumors had a significantly increased survival compared to men with ERCC1-positive tumors (median survival, 11.8 months v 7.9 months; P = .005). Conversely, women who were ERCC1 negative did not have a survival advantage over ERCC1-positive women.CONCLUSION:
We confirmed previous reports that ERCC1 expression is predictive for outcome in patients treated with carboplatin and gemcitabine. Patients with ERCC1-negative tumors had an increased survival compared to patients with ERCC1-positive tumors and this difference was mainly attributable to a survival difference among men.
