Kaplan Meier curve to compare overall survival for the young, middle-age and old groups. Overall no significant difference can be shown (p = 0.094). Comparison of the isolated subgroups demonstrates a significant difference in comparison of middle-age vs. old group (p = 0.038). No differences were found for young vs. middle-age (p = 0.179) and young vs. old groups (p = 0.845). Perioperative deaths were excluded
