First-line cisplatin (P) with docetaxel (TXT) or vinorelbine (VNR) in patients with advanced non-small cell lung cancer: A randomized phase II trial of the Gruppo Oncologico Italia Meridionale

Abstract

e19042 Background: P-based doublets are considered standard therapy for advanced NSCLC. The GOIM consider P/VNR as a reference treatment. P/TXT doublet has been reported to be active but it's not well known its real impact on QoL in comparison to P/VNR. Methods: Pts received either 6 courses of P/TXT or P/VNR with QoL and safety being the primary endpoints. Secondary endpoint included response rate, TTP, OS, and tolerability. Patients with stage IV/IIIB, age ≤70, and ECOG PS 0–1, were eligible. Sample size was calculated according to Fleming's single-stage procedure. QoL was analysed using the EORTC questionnaire, responses and toxicity according to the RECIST and NCI-CTC criteria. Pts were randomized to: TXT 75 mg/m2 over 60 min followed by P 75 mg/m2 on d1 every 21 d, or VNR 30 mg/m2 on d 1,8 and P 80 mg/m2 on d1 every 21 d. Results: From 12/06 to 3/08 86 pts were enrolled: P/TXT 42pts, M/F 32/10, IIIB/IV 8/34, squamous/not-squamous:13/29, median age 61 (r 41–70); P/VNR 44 pts, M/F 35/9, IIIB/IV 10/33, squamous/not-squamous 14/30, median age 62 (r 44/70). No statistically significant differences were observed in QoL among the two arms. Detailed analysis of side-effects showed no difference among the two regimens with the exception of G3–4 neutropenia and leukopenia with were slightly higher in the P/VNR arm (p=0.02 and p=0.0005 respectively). The use of G- CSF/darbopoietin was more frequent in pts treated with P/VNR than in the P/TXT arm (p=0019). Conclusions: Final data show an equivalence among the two arms regarding QoL and activity but with a slightly more hematological toxicity in the P/VNR arm. Both regimens are to be considered as standards in the treated of advanced NSCLC. [Table: see text]
