Analysis of clinical features and prognostic factors in middle and old age patients with angioimmunoblastic T-cell lymphoma

Objective To investigate clinical features,diagnosis and treatment of angioimmunoblastic T-cell lymphoma(AITL)in middle and old age patients.Methods This was a retrospective study.A total of 33 middle-aged and elderly patients(a median age of 64 years,range 47~85 years)with AITL admitted to our hospital from May 2008 to March 2017,including 54.5%male(18 cases),were enrolled in this study.Clinical manifestations,pathology,imaging and survival data of patients were collected.The objective response rate(ORR)of patients with different therapeutic regimens was analyzed.The survival analysis was conducted by using the Kaplan-Meier method,the survival rate was analyzed by using the Log-rank method,and multivariate analysis was conducted by using the proportional hazards regression model.Results The median overall survival(OS)was 26.0 months(8.5-43.5 months).The 1-year,3-year and 5-year OS rate was 66.7%(22 cases),45.5%(15 cases)and 24.2%(8 cases),respectively.The ORR of first-line chemotherapy with CHOP-like regimens(cyclophosphamide,doxorubicin,vincristine,prednisone)was 65.5%(19/29)and the incidence of serious adverse reactions was 64.5%(20/31).Single-factor chi-square testing showed that age≥60 years,Barthel score≥90,Eastern Cooperative Oncology Group performance status score(ECOG-PS)≥2,anemia,International prognostic index(IPI)score of 4~5,receiving chidamide treatment were influncing factors for the prognosis in middle-aged and elderly patients with AITL(χ2=5.103,4.306,6.004,4.030,6.348 and 4.080,P<0.05).Cox multivariate analysis showed that age≥60 years and receiving chidamide treatment were independent prognostic factors affecting the 5-year survival rate of middle-aged and elderly AITL patients(OR=0.313 and 4.964,P<0.05).That the OS was better in the group receiving chidamide treatment than in the group without chidamide treatment(P<0.05).Conclusions Clinical features of AITL are diverse and lack of specificity.Most patients present with advanced stage AITL at the initial diagnosis.The 5-year OS rate is low.AITL patients aged over 60 years have a poor prognosis.Chidamide can improve the OS rate.
