Treatment guided by ERCC1, RRM1, and BRCA1 protein expression in patients with advanced-stage NSCLC
e19094 Purpose: We investigated whether Treatment Guided by ERCC1,RRM1 and BRCA1 protein expression levels could improve clinical outcomes in Patients With Advanced-Stage NSCLC. Experimental Design: Eligibility: Main inclusion criteria: Stage IV or stage IIIB NSCLC; Eastern Cooperative Oncology Group(ECOG) performance status (PS) 0–1; Measurable disease; Adequate bone marrow, kidney, liver function. Main exclusion criteria: previous NSCLC therapy; Central nervous system metastasis; Requiring immediate intervention or Untreated with radiation within 28 days of study regimen initiation. Previously untreated patients with Stage IV or stage IIIB NSCLC(N=180): Standard chemotherapy group(N=60): Cisplatin 75mg/m2 Day1+Vinorelbine 25mg/m2 Days 1,8 every 28 days; Individualized chemotherapy group (N=120) (ERCC1,RRM1 and BRCA1 protein expression assayed with IHC); Low ERCC1 protein expression subgroup: Cisplatin 75mg/m2 Day1+Vinorelbine 25mg/m2 Days 1,8 every 28 days; High ERCC1 protein subgroup: Vinorelbine 25mg/m2 Days 1,8+Gemcitabine 1250mg/m2 Days 1,8 every 28 days. Description of Current Analysis: ERCC1,RRM1 and BRCA1 protein expression assayed with IHC; Assigned treatment based on ERCC1 protein expression; Primary endpoint: overall response rate; Secondary endpoints: Overall survival (OS), Progression-free survival (PFS).
