FIGURE 2 Relative frequency of thymoma histotypes by center volume and geographic region. A, Frequency of thymoma subtypes, ordered by size of center and geographic region. B, The frequency of thymoma subtypes by region and by high- and low-volume centers. “High volume centers” are those contributing more than 50% of the total cases per region.

FIGURE 3 Recurrence by thymoma histotype for specific stage groups. Cumulative incidence of recurrence by World Health organization (WHO) type (R0 patients) for (A) stages I + II, (B) stage III, and (C) stage IVa. Curves for stage IVb are not shown due to low case numbers. The table inserted in (A) shows pairwise comparisons for stages I + II with adjusted p values, asterisk denotes p ⩽ 0.05. Data for stages III and IVa are not shown because all results are nonsignificant.
