(A) Overall survival (OS) between R0/R1-margined patients with or without radiation therapy (RT). Due to insufficient OS data, the average OS could not be calculated. However, the estimated 5-year survival rate was both 100%. Predicted 10-year survival rates were 66.7 ± 27.2% and 100%, respectively. (B) Progression-Free survival (PFS) between R0/R1-margined patients with or without radiation therapy. Among R0/R1 patients, the mean PFS was 94.0 ± 21.9 months for those undergoing RT and 111.0 ± 27.3 months for those who did not (p value = 0.901).
