Figure 1 Inclusion flow-chart. Patients excluded from the study (white boxes) and included in the study.

Figure 2 Kaplan-Meier curves for overall survival. A: Kaplan–Meier curve of overall survival (OS) stratified by Timing of Recurrence. Median OS for patients with recurrence < 3 years was 44 mo (95% Confidential interval 29-59 mo) vs 108 (95% Confidential interval 79-137 mo) for those with recurrence ≥ 3 years (P = 0.011); B: Kaplan Meier curve of post recurrence OS stratified by Timing of Recurrence. Median post recurrence OS for patients with recurrence < 3 years was 24 mo (95% Confidential interval 16-32 mo) vs 13 (95% Confidential interval 0-30 mo) for those with recurrence ≥ 3 years (P = 0.991).
