Background: This study aims to compare efficacy and safety of two widely used combinations of cisplatin (P) in this setting: as etoposide (E) and vinorelbine. This last, in its oral formulation (oV) which has achieved comparable results as the IV formulation and patients (pts) prefer it. Methods: Pts between 18-75years, with histologically proven untreated and unresectable LA-NSCLC, adequate respiratory function, V20 ≤ 35% and ECOG-PS 0-1, were randomized 1:1 to oV-P arm:2 induction cycles (cy) of oV-P followed by 2 cy more with RT; or to E-P arm: 2 cy of E-P concomitants to RT. Both arms with a total radiation dose of 66Gy administered 2 Gys daily. Primary endpoint was progression free survival (PFS) by RECIST 1.1. Secondary endpoints: overall response rate (ORR), overall survival (OS) and safety. With α-error of 0.05 (one-tailed test) and 0.1 β-error, median PFS unacceptable for the oV-P arm of 10 months (m) (p0) and a very acceptable of 15 m (p1), 122 eligible pts were required. Results: 140 pts from 23 institutions of SLCG were randomized between 08/2011-12/2014. 134 pts were treated (66 in oV-P and 68 in E-P arms). Results based on this 134 pts are presented. Median age 62 years [39-76]; PS 0/1, 45%/55%; current smoker 51%; squamous cell 51%; stage IIIB 54%. 244 and 131 cy were given in the oV-P and E-P arms, respectively. All irradiated pts in oV-P arm received at least 60Gy, 7 pts in the E-P arm received less than 60Gy (4 due to toxicity). 1 pt (1.5%) in oV-P arm and 12 pts (17.6%) in E-P arm presented esophagitis G3/4 (p = 0.002). 121 confirmed eligibility for efficacy analysis. ORR were 39 (64%) and 40 pts (67%) in the oV-P and E-P arms, respectively (p = 0.889). After 16 m [1-43] of follow-up, 66% pts progressed and 43% pts died. Median PFS is 11.4 m (IC95%; 6-17) in oV-P arm and 11.8 m (IC95%; 7-16) in E-P arm (p = 0.374). Conclusions: Both regimens achieve similar efficacy however oV-P has less toxicity, especially esophagitis G3/4. Further follow-up is needed for the survival analysis.
