Peripheral T-cell lymphomas (PTCLs) are uncommon and their frequency is regionally heterogeneous. Several studies have been conducted to evaluate the clinical features treatment outcomes of this disease entity, but majority these were in limited areas, making it difficult comprehensively analyze relative features. Furthermore, no consensus for PTCLs has established. Therefore, we an Asia-specific study understand assess treatments Asian patients.We performed a multinational, multicenter,...
