Overall survival curves and disease-free survival curves. The 5- and 10-year overall survival rates were 93.6 and 89.6% for group-A (n=258) vs 94.5 and 87.8% for group-B (n=256), respectively (P=0.5526). The 5- and 10-year disease-free survival rates were 84.7 and 76.6% for group-A vs 83.1 and 74.1% for group-B, respectively (P=0.6137).
