Class III β-tubulin in advanced NSCLC of adenocarcinoma subtype predicts superior outcome in a randomized trial

Platinum-based doublets are the cornerstone of treatment in advanced non-small-cell lung cancer (NSCLC) and often include vinorelbine or taxanes. A predictive biomarker is greatly needed to select chemotherapy-sensitive patients for these microtubule-interfering agents. Class III β-tubulin (TUBB3) has been shown of value in NSCLC, but evidence is not uniform. Accordingly, we explored the predictive role of TUBB3 in advanced NSCLC.
