ABSTRACT
Objective To investigate the prognostic value of pretreatment 18F-fluorodeoxyglucose (FDG) PET/CT imaging on extranodal nasal type natural killer/T-cell lymphoma (ENKTL).Methods Thirtyfive patients (20 males,15 females,average age 45 years) diagnosed as Ann Arbor stage Ⅰ-Ⅱ ENKTL from February 2013 to February 2016 were retrospectively analyzed.All patients were pathologically confirmed and underwent 18F-FDG PET/CT before treatment.The maximum standardized uptake value (SUVmax),international prognostic index score (IPI),serum lactate dehydrogenase (LDH),and immunohistochemical results were recorded.Patients were followed up for 2 years.The relationships between SUVmax,progression-free survival (PFS),pathological features and IPI were assessed using Fisher exact test.Results There were 18 ENKTL patients with progression,and 17 had no progression.Patients with SUVmax ≥ 12.2 had worse prognosis than those with SUVmax＜ 12.2 (P =0.001).There were correlations between SUVmax and Ki-67 (r=0.701,P=0.001),SUVmax and CD56 (r=0.393,P=0.032),SUVmax and IPI (r=0.787,P＜0.01),respectively.It was also found that SUVmax,Ki-67,CD56 and IPI were related to PFS (all P＜0.05).Conclusion SUVmax of 18F-FDG could be used as an important prognostic indicator for early ENKTL.
ABSTRACT
@#Objective To investigate the condition of utilization of glasses aids adaption in Shanghai. Methods The numbers who accepted the services, funds invested, the models, etc. in 16 districts of Shanghai between 2012 and 2014 were collected, and analyzed with descriptive analysis, concentration index and correlation analysis. Results A total of 17,498 persons accepted glasses aids adaption services, which cost 335.37 yuan per person. The concentration index was 0.0951. Conclusion The glasses aids adaption service works well in Shanghai, but is variable among the districts.
