Survival for patients with poor preoperative Karnofsky Performance Scale score (KPS) stratified by their preoperative KPS score. Median survival for patients with preoperative KPS score 60 was 6.6 months, where the 6-, 12-, and 18-month survival rates were 35%, 21%, and 9%, respectively. Median survival for patients with preoperative KPS score of 40–50 was 7.9 months, where the 6-, 12-, and 18-month survival rates were 11%, 8%, and 3%, respectively. Median survival for patients with preoperative KPS score of 20–30 was 3.7 months, where the 6-, 12-, and 18-month survival rates were 6%, 4%, and 4%, respectively. In Log-rank analysis, there was no statistical significance in survival between the cohorts (p > 0.05).
