| Description
| - Chemotherapy is an important modality of treatment for non-small cell lung cancer (NSCLC). The aim of our study was to assess the relation of mRNA levels of DNA repair genes excision repair cross-complementary group 1 (ERCC1), ribonucleotide reductase subunit M1 (RRM1) and breast cancer 1 (BRCA1), in surgically-resected tumor tissues from patients who underwent adjuvant chemotherapy, to the disease-free interval (DFI) and overall survival (OS). We investigated if potential residual tumor cells after resection reflect properties of the primary tumor and response to chemotherapy according to the level of predictive markers with respect to current knowledge. We studied a group of 90 patients with NSCLC who had undergone curative lung resection. We found longer OS for patients with adenocarcinoma with higher expression of the RRM1 mRNA (p=0.002), and for patients with SCC with higher expression of the BRCA1 mRNA (p=0.041). In patients with NSCLC of stage III, we found longer DFI in those with higher expression of RRM1 (p=0.004) and ERCC1 (p=0.038). Patients who had been treated with adjuvant chemotherapy and had shown lower expression of repair genes had adverse prognosis. We observed that the assessment of DNA repair gene level in primary tumors treated by surgical resection had prognostic significance and did not predict response to adjuvant chemotherapy.
