Efficacy of paclitaxel‐carboplatin with bevacizumab as a late‐line therapy for patients with advanced nonsquamous non‐small cell lung cancer: A platinum rechallenge

BACKGROUND: There is no well‐established late‐line treatment for advanced nonsquamous non‐small cell lung cancer (NSCLC). Therefore, we retrospectively determined the efficacy and safety of platinum rechallenge with paclitaxel‐carboplatin and bevacizumab in patients with nonsquamous NSCLC as a late‐line therapy in a clinical setting. METHODS: Thirty patients with nonsquamous NSCLC who received paclitaxel‐carboplatin with bevacizumab therapy as a late‐line treatment at Sendai Kousei Hospital (Miyagi, Japan) between December 2011 and December 2021 were enrolled into the study. The efficacy and safety of this treatment were evaluated. The patients were further categorized into responders and nonresponders, and predictive factors of treatment response were estimated. RESULTS: The median progression‐free survival (PFS) was 6.3 (range, 4.9–6.8) months, and the median overall survival (OS) was 11.8 (range, 7.2–17.2) months. There were no significant differences in PFS and OS between patients with and those without epidermal growth factor receptor mutations. In the univariate analyses of this study, responders were younger than nonresponders (p = 0.012). No fatal adverse events were reported. CONCLUSIONS: With the increase in the number of treatment options in recent years, the sequence of treatments and overall therapeutic strategy are becoming increasingly important. Thus, platinum rechallenge with paclitaxel‐carboplatin and bevacizumab, a late‐line treatment for patients with nonsquamous NSCLC, may be an effective therapeutic option.
