Abstract:
ObjectiveTo analyze the clinical characteristic of the nasal type extranodal NK/T cell lymphoma(ENKL)as well as the therapeutic effects for different treatment methods and element that would affect prognosis.MethodsReview and analyze the 27 patients with pathologically confirmed ENKL patients received radiotherapy (3 cases),chemotherapy (9 cases),combination of radiotherapy and chemotherapy (15 cases),3 of whom received auto-HSCT.Detailed B symptoms,lactate dehydrogenase (LDH),performance status(PS)scores,international prognostic index(IPI),Ann Arbor stage and therapeutic modality were included in univariate analysis.ResultsThe average overall survival time was 32 (2-42) months.The 1,2and 3 year overall survival (OS) rates were 79.5 ％,71.6 ％,53.7 ％,respectively.The 2-year overall survival of patients who was early stage (stage Ⅰ + Ⅱ ) was 83.3 ％,and those who was advanced stage(stage Ⅲ+Ⅳ) was 62.3 ％ (P =0.368).Among the patients in early stage,after radiotherapy or chemotherapy,4 cases achieved OR (overall response) which is complete remission (CR) or partial remission (PR),9/10 in combination of radiotherapy and chemotherapy achieved OR. While among those in their advantage stage,the OR in chemotherapy is 2 cases,2/5 in combination of radiotherapy and chemotherapy.In univariate analysis,age and short-term response were main factors of survival(P ＜0.05).ConclusionTo treat the nasal ENKL in the early stage,radiotherapy can achieve a better effect,while combination of radiotherapy and chemotherapy is an important method for patients in advantage stage.Age and short-term response may be.prognostic factors of nasal type ENKL.
