Figure 2. Comparison of recurrence-free survival and overall survival according to the group classification method.
A. Recurrence-free survival according to putative molecular classification. EBV-positive and MMR-deficient subgroups showed favorable prognosis. However, pGS and pCIN subgroups showed relatively poor recurrence-free survival. Separate analysis of pGS and pCIN subgroups showed no significant difference between the two subgroups (P = 0.511). B. Recurrence-free survival according to histologic-molecular classification. On separate analysis of D-pGS and I-pCIN subgroups, the I-pCIN subgroup showed a trend toward longer recurrence-free survival (P = 0.069). C. Overall survival according to the putative molecular classification. D. Overall survival according to the histologic-molecular classification.
