Clinical Analysis for Thymic Carcinoma / 대한흉부외과학회지

ABSTRACT

BACKGROUND: Thymic carcinoma is a very rare disease and treatment modality is not standardized. So, we report our experience of management of thymic carcinoma. MATERIAL AND METHOD: Between 1984 and 1998, eight patients with thymic carcinoma were treated at Keimyung University Dongsan Medical center. RESULT: The median age was 46 years with a range of 23 to 67 years. Chief complaint was a anterior chest pain. Histologic subtypes included two lymphoepithelioma-like carcinoma, two squamous cell carcinoma, one basaloid carcinoma, and three mixed type. Clinical staging was classified to stage I in 2, stage II in 4, stage III in 1, and stage IVA in 1 according to the modified Masaoka staging system. Four patients underwent complete resection and three patients were found to have incomplete resection by histologic evaluation. One patient underwent only biopsy due to pericardial dissemination and invasion of adjacent organ. All patients had adjuvant chemotherapy, radiation therapy was administered to five patients for positive resection margin and above stage III. The median follow up period was 55.3+/-64.6 months, three patiants died and four patients are alive without recurrence. One patient in recurrence had two times re-operations and adjuvant chemoradiotherapy. He is still alive. CONCLUSION: We concluded that completely surgical resection and adequate adjuvant chemoradiotherapy after early diagnosis are useful to management of thymic carcinoma.
