NOTE: statistically significant correlations are shown in bold face. Survival was determined from the date of surgery to the time of event (death) using the Kaplan–Meier method. Non-cancer-related deaths were excluded from analyses. Statistical significance of differences in cumulative survival curves was evaluated using log-rank tests.
