Keywords: thymoma, prognosis, histopathological classification
The aim of this study is to evaluate the treatment results of nine cases with thymoma and five cases with thymic carcinoma which were diagnosed and treated at Erciyes University Medical Faculty by using Marino and Müller-Hermelink and Kirchner (MMHK) histopathologic classification. According to this classification, thymomas are divided into 4 groups: Medullary, mixed, organoid and cortical. Two subgroups of thymic carcinomas are well differentiated thymic carcinoma and high grade carcinomas. Recently some publications show that MMHK histological classification has prognostic importance, independent of tumor stage. Our treatment results are in harmony with the literature showing that medullary and mikst thymomas have good prognosis and the other subgroups of thymoma and thymic carcinomas have poor prognosis.
