| Outline of Final Research Achievements |
Molecular pathological studies were was performed for adult mediastinal lymphoproliferative disorders in the Asia. In thymic MALT lymphoma, a frequent gene methylation was detected. In particular, p14 (ARF) gene methylation was associated with a larger tumor size, suggesting a role in tumor progression. In primary mediastinal large B-cell lymphoma, frequent abnormalities of CIITA and PDE5A genes have been reported from Western countries. We studied these abnormalities using FISH technique, although no significant abnormalities were found. This may suggest genetic difference between the Western and Asian cases. Progress of thymic MALT lymphoma in these 20 years was studied. After a critical discussion with distinguished hematopathologists, I published the results as the first author in the 4th WHO classification of thymic tumors.
