Review Multicenter Study
Thymoma: results of a multicentric retrospective series of 149 non-metastatic irradiated patients and review of the literature. FNCLCC trialists. Fédération Nationale des Centres de Lutte Contre le Cancer.
Between 1979 and 1990, 149 patients with non-metastatic thymomas were treated in ten French cancer centers. Patients were staged according to the 'GETT' classification, derived from that of Masaoka. There were 13 stage I patients, 46 stage II, 58 stage III and 32 stage IVA. ⋯ Four factors could predict a worse overall survival in the multivariate analysis: mediastinal compression on presentation (p < 0.001), absence of chemotherapy (p < 0.001), biopsy alone (p = 0.003), and young age (p = 0.013). A worse DFS was predicted by mediastinal compression on presentation (p < 0.001), absence of chemotherapy (p < 0.001), young age (p = 0.006), and stages III-IVA (p = 0.04). Future therapeutic strategies are discussed and the literature is reviewed.
