Kaplan–Meier analysis of overall survival (OS) stratified by tumor volume. The difference in OS between the large tumor group (n = 135) and the small tumor (n = 135) group did not reach statistical significance (5-year OS rate: 84.8% vs 90.8%, log-rank test, p = 0.083).

Kaplan–Meier analysis of disease-free survival (DFS) stratified by tumor volume. The large tumor group had a significantly poorer DFS than the small tumor group (log-rank test, p = 0.042).

Kaplan–Meier analysis of local recurrence-free survival (LRFS) stratified by tumor volume. The large tumor group had a higher LR rate than the small tumor group (log-rank test, p = 0.030).

Kaplan–Meier analysis of distant metastasis-free survival (DMFS) stratified by tumor volume. There was no statistically significant difference in DMFS in the two patient groups (log-rank test, p = 0.113).
