Materials and Methods: Fifty-five patients were operated on for thymoma have been retrospectively evaluated according to their demographics, clinical characteristics, pathologies, complications, recurrences and survival.
Results: The mean SUVmax value was found to be 5.5 ± 2.05 and showed no correlation with mass diameter or stage (p = 0.284 and p = 0.176, respectively). The mean survival was 55.9 ± 35.31 months in the R0 resection group. Overall survival was not correlated with age and mass diameter at a statistically significant level (p = 0.056, p = 0.108 respectively). There was no difference in the frequency of recurrence between the WHO stages (p = 0.775). Conversely, when classified as per the Masaoka–Koga classification, recurrence was detected in all stage-4 patients (p < 0.001).
Conclusions: To date, there is no practical structure that classifies and integrates prognostic factors and creates a usable system out of them but, in thymomas, the best results are achieved by complete surgical resection.
