RESUMEN
Purpose To explore the prognostic value of deletion of the TNFAIP3 gene in natural killer/T-cell lymphoma,nasal type detected with fluorescence immunophenotyping and interphase cytogenetics as a tool for the investigation of neoplasm (FICTION).Methods FICTION was performed to detect the abnormalities of TNFAIP3 gene in 109 cases of natural killer/T-cell lymphoma,nasal type.Results TNFAIP3 deletion was found in 25/79 detectable cases.The deletion of TNFAIP3 was positively correlated with the International Prognosis Index (IPI) (P =0.019).Conclusion Frequent deletion of TNFAIP3 was associated with IPI in natural killer/T-cell lymphoma,nasal type,suggesting the important prognostic value of TNFAIP3 in the natural killer/T-cell lymphoma,nasal type.
