Prognostic and predictive role of ERCC1 protein expression in locally advanced stage III non-small cell lung cancer.
Systemic therapy improves the survival and quality of life of patients with advanced stage non-small cell lung cancer (NSCLC). Several new therapeutic options have emerged for advanced NSCLC, incorporating novel cytotoxicity agents (taxanes, gemcitabine, pemetrexed) and molecular-targeted agents (erlotinib, bevacizumab) and the optimal prognostic marker for survival remains unclear. The aim of the present study was to assess the prognostic value of the clinicopathologic features and excision repair cross-complementation group-1 (ERCC1) in locally advanced NSCLC patients that received cisplatin-based chemotherapy. ⋯ Prognostic factors with overall survival were performance status, cigarette smoking, stage, weight loss and ERCC1. While as regard progression-free survival prognostic factors were stage, weight loss, ERCC1 and degree of positivity of ERCC1 progression. It was found that ERCC1 protein expression might play an important role in the prognosis of locally advanced NSCLC patients treated with cisplatin-based adjuvant chemotherapy.

Previous studies have suggested an association between preoperative plasma fibrinogen and D-dimer levels and prognosis in patients with non-small cell lung cancer (NSCLC) who underwent surgery. In this study, we evaluate the value of pre- and post-operative plasma fibrinogen and D-dimer levels and changes in the levels of the two markers between before and after operation in predicting tumor recurrence and metastasis in NSCLC patients who undergoing radical surgery. One hundred and eighty-four patients with I-IIIA NSCLC were enrolled in this study, and plasma fibrinogen and D-dimer levels were measured in these patients before and after surgery, respectively. ⋯ Patients with pre- and post-operative fibrinogen and D-dimer positivities had a shorter disease-free survival (DFS) than those without (P = 0.002 and P < 0.001 for fibrinogen, and P = 0.003 and P = 0.001 for D-dimer). Multivariate Cox regression analyses revealed that pre- and post-operative fibrinogen and D-dimer positivities were independent predictors for unfavorable DFS. Our results indicate that pre- and post-operative plasma fibrinogen and D-dimer levels may be useful biomarkers in predicting tumor recurrence and metastasis for patients who undergo curative surgery.
