(A) Overall survival stratified by age group in elderly patients. Cumulative overall survival at 3, 6, and 9 months was 96.0%, 88.9%, and 84.2% in elderly patients aged 75–79 years (dotted line), 93.6%, 90.1%, and 86.5% in elderly patients aged 80–84 years (solid line), and 100.0%, 92.3%, and 73.8% in elderly patients aged ≥85 years (dash‐dot‐dash line), respectively (p = 0.960). (B) Progression‐free survival stratified by age group in elderly patients. Cumulative progression‐free survival at 3 and 6 months was 80.2% and 57.3% in elderly patients aged 75–79 years (dotted line), 75.3% and 42.7% in elderly patients aged 80–84 years (solid line), and 71.4% and 49.4% in elderly patients aged ≥85 years (dash‐dot‐dash line), respectively (p = 0.566).
