      Background:
      This multicenter, single-arm, open-label, phase 2 study assessed the efficacy and safety of carboplatin plus weekly nanoparticle albumin-bound paclitaxel in elderly patients with previously untreated advanced squamous non-small-cell lung cancer, selected based on the Mini Nutritional Assessment short-form scores (MNA-SF).

      Method:
      Patients received carboplatin (area under the curve: 6) on Day 1, and nanoparticle albumin-bound paclitaxel (100 mg/m[2]) on Days 1, 8, and 15, every 28 days for ≤4 cycles. Eligibility criteria included an MNA-SF score of ≥8 points. The primary endpoint was the objective response rate.

      Result:
      Thirty patients with a median age of 76 (range, 70–83) years were enrolled. The objective response rate was 50.0% (95% confidence interval: 31.3–68.7%), which met the primary objective of this study. The disease control rate was 73.3% (95% confidence interval: 54.1–87.7%). At a median follow-up of 15.0 months, the median progression-free and overall survival was 7.1 and 19.1 months, respectively. The most common treatment-related adverse event of Grade ≥3 was neutropenia (66.7%). Non-hematological adverse events of Grade ≥3 were minor. Well-nourished patients, based on the MNA-SF, experienced fewer adverse events of Grade ≥3 compared to patients at risk of malnutrition. All treatment-related adverse events were tolerable and reversible. There were no treatment-related deaths.

      Conclusion:
      Carboplatin plus weekly nanoparticle albumin-bound paclitaxel is effective and well tolerated as a first-line treatment for elderly patients with advanced squamous non-small-cell lung cancer. Eligibility based on MNA-SF screening may be useful in determining acceptable toxicity.
