METHODS
Eighteen patients were treated median 5400 cGy radiotherapy
between 1995-2010. Diagnosis of patients were thymoma
(n=10), thymic carcinoma (n=7), thymic neuroendocrin carcinoma
(n=1). R0 resection was made on 12 of them. According
to prognostic stratification with Masaoka stage and WHO
classification, there were 5 good, 7 moderate, and 6 poor risk
patients. Survival was calculated from diagnosis.
RESULTS
A total of 33% patients were recurred median 29.5 months
with 34 months follow-up. Local control, median overall and
disease-free survival for all patients were 77%, 113 months,
and 105 months. Local control for good, moderate, poor risk
groups were found 100%, 71%, 50%. There were significant
differences survival rates for Masaoka stage, R0 resection, and
prognostic groups.
CONCLUSION
Prognostic risk classification was found to be better predictive
in terms of local control and survival.
