Value of 18 F-FDG PET/CT for prognosis evaluation in small cell lung cancer with normal serum lac-tate dehydrogenase / 中华核医学与分子影像杂志

Objective To evaluate the value of 18 F-FDG PET/CT imaging in predicting the progno-sis of newly diagnosed SCLC with normal serum LDH ( SCLC-nsLDH) . Methods A total of 68 SCLC pa-tients (59 males, 9 females, median age:58.5 years) proved by pathology between June 2005 and Decem-ber 2016 were retrospectively analyzed. All patients underwent 18 F-FDG PET/CT. The general information of patients, including LDH, NSE, OS, PFS and SUVmax , were recorded. SUVmax differences were analyzed with Mann-Whitney u test. Life-table method and Kaplan-Meier analysis were used to estimate the survival rate and median survival time. The survival function curve was drawn. Log-rank test was used to analyze whether there existed statistical differences in survival period among different groups. Cox regression analysis was used for screening the influencing factors of prognosis. Results ( 1) In 68 SCLC patients, there were 38 cases with limited disease ( LD) and 30 cases with extensive disease ( ED) . There were 3 cases in stageⅠ, 7 cases in stage Ⅱ, 29 cases in stage Ⅲ, 29 cases in stage Ⅳ. The median SUVmax of the primary tumor was 11.35 (9.90, 13.90). There was no significant difference between the median SUVmax of LD group and that of ED group:11.05(9.72, 13.60) vs 12.25(10. 05, 14.12)months;z=-0.797, P=0.426. The median serum LDH was 195.15(171.00, 220.80) U/L. (2) The median follow-up time was 18(range:2-101) months. The disease developed in 46 patients and 35 patients died. The median OS was 23 (95%CI:13.3-32.7) months and median PFS was 17 (95% CI: 11.4-22.6) months. (3) ROC curve showed the optimal SUVmax cutoff value was 10.85. The OS of patients with SUVmax≤10.85 ( n=25) and with SUVmax>10.85 (n=43) were 40.0(95% CI:2.5-77.5) months and 18.0(95% CI:13.3-22.7) months(χ2=8.956, P=0.003), respectively. (4)Weight loss, VALG stage and primary tumor SUVmax were independent prog-nostic factors for OS (all P<0.05). Only VALG stage was an independent prognostic factor for PFS (P<0. 001) . Conclusion 18 F-FDG PET/CT can help to differentiate the different prognosis of SCLC-nsLDH patients, and provide more evidence for the choice of individual treatment strategy.

Value of 18F-FDG PET/CT with Volume Metabolic Parameters for Prognosis Evaluation in Limited-Disease Small Cell Lung Cancer / 中山大学学报(医学科学版)

[Objective]To investigate the prognostic value of 18F-FDG PET/CT with different metabolic parameters in newly diagnosed limited-disease(LD)small cell lung cancer(SCLC).[Methods]Retrospective analysis was carried out in the patients between June 2005 to December 2016 in our hospital confirmed of LD SCLC by pathology or cytology and comprehensive imaging. Fifty-four patients were recruited. Record the general characteristics of patients,pre-treatment KPS score,smoking status,weight loss,serum LDH,NSE,OS,PFS. All lesions(primary lesions + metastases)were sketched out within one VOI,and the SUVmax, SUVmean and SUVpeak in the VOI were automatically measured and recorded. The automatic measurement was performed by the fixed threshold method. The thresholds of tumor of MTV and TLG were 40% and 50% of SUVmax. The TLG and MTV were identified as TLG40%,TLG50%,MTV40% and MTV50% respectively. Kaplan-Meier method was used for survival analysis. All the prognostic factors were analyzed by Cox model.[Result]The median SUVmax was 13.92(2.61~43.28),the median of SUVmean was 8.31(1.71~26.85) and the median of SUVpeak was 10.51(1.49 ~ 27.48). The median of TLG40% was 340.22(16.58 ~ 2827.26),the median of TLG50%was 215.645(1.70 ~ 2270.36),the median of MTV40% was 36.71(1.15 ~ 259.47 cm3),the median of MTV50% was 19.65(0.93 ~1900.00)cm3. Univariate and multivariate analysis of metabolic index and prognosis showed that TLG50% was the prognostic factor of OS(P = 0.013),but not of PFS(P > 0.05). The SUVmax,SUVmean and SUVpeak were not the prognostic factors of OS and PFS(P >0.05).[Conclusion]The volume metabolic parameters TLG50%was the independent prognostic factor of the overall survival time of the LD SCLC. The volume metabolic parameters (TLG and MTV) of 18F-FDG PET/CT were related to the prognosis of SCLC ,which could provide the basis for individual chemotherapy.

ObjectiveTo explore the prognostic value of pretreated maximum standardized uptake value (SUVmax) using 18-fluorodeoxyglucose positron emission tomography with computed tomography (18FDG PET/CT) in locally-advanced nasopharyngeal carcinoma (NPC) treated by intensity-modulated radiotherapy (IMRT).MethodsOne hundred and forty previously untreated stage Ⅲ - Ⅳb ( UICC/AJCC 6th) patients with biopsy-proven nasopharyngeal carcinoma were examined.All of the enrolled patients accepted whole body/head-neck 18FDG PET/CT before radical IMRT. 18FDG uptakes were recorded as SUVmax of primary tumor (SUVmax-P) and SUVmax of cervical lymph nodes (SUVmax-N).The relationships between SUVmax and long-term clinical outcomes were analyzed.ResultsThe median SUVmax-P was 10.4,and the median SUVmax-N was 6.2.The SUVmax-P was weakly correlated with T-stage ( R =0.279,P =0.001 ).The SUVmax-N was weakly correlated with N stage ( R =0.334,P =0.000 ).There were no difference of the median SUVmax-P (9.2 vs.10.4,U =560.50,P =0.805 ) and the median SUVmax-N (4.0vs.5.0,U =576.00,P =0.908) between patients with and without local recurrence.The median SUVmax-P of patients with distant metastasis was significantly higher than those without metastasis (11.9 vs.9.8,U =987.50,P =0.014).The SUV of 10.2 was taken as a cut-off for high and low uptake tumors.For patients with SUVmax-P ＞ 10.2,the 5-year distant metastasis-free survival (DMFS) and 5-year overall survival (OS)were significantly higher than those with SUVmax-P ≤ 10.2 (69.1％ vs.95.5％,x2 =15.88,P =0.000;68.4％ vs.94.0％,x2 =15.56,P =0.000,respectively).Multivariate analysis showed that SUVmax-P was the only independent risk factor of 5-year DMFS and OS ( HR =7.87,P =0.001 and HR =5.14,P =0.003). Conclusion SUVmax-P is a useful biomarker predicting long-term clinical outcomes in newly diagnosed locally-advanced NPC patients.

Association between skin prick test of dust mites and serum specific IgE in diagnosis of mite allergy / 中华检验医学杂志

Objective To investigate the association between the results of Dermatophagoides pteronyssinus ( Der p) and Dermatophagoides farinae ( Der f) allergen SPT and serum sIgE in diagnosis of IgE-mediated mite allergy.Methods A total of 166 allergic outpatients with positive expression of serum sIgE of Der p and Der f diagnosed in Beijing Tongren Hospital,the General Hospital of Shenyang Military Region and Guangzhou Institute of Respiratory Disease were enrolled in the study.The SPT was performed by injecting liquid containing the allergen of Der p and Der f.One hundred ninety healthy subjects with negative serum sIgE of Der p and Der f were assigned as controls according to paired design ratio,1 to 1.The sensitivity and specificity of SPT used Der p and Der f allergen were evaluated in the diagnosis of mite allergy.The association between the results of SPT and serum sIgE was analyzed by linear regression method.Results In the allergic group,the positive rates of SPT for Der p and Der f were 98.80％ ( 164/166) and 95.18％ (158/166) respectively.In the control group,the positive rate of STP for Der p and Der f were 2.11％ (4/190) and 1.58％ (3/190) respectively.The SPT results of Der p and Der f showed significant statistical difference between healthy subjects and allergic patients (x2 =285.5,386.3;P＜0.01 ).The sensitivity and specificity of the SPT were 98.80％ (164/166) and 97.89％ (186/190) for Der p and 95.18％ (158/166) and 98.42％ (187/190) for Der f,respectively.There was a significant association between SPT and sIgE with linear correlation analysis( r =0.737,0.708;P ＜ 0.O1 ).Conclusions Both SPT of Der p and Der f is highly sensitive and specific.At the same time,SPT has a significant positive correlation with sIgE.It can be used as an accurate,convenient and fast test in diagnosis of mite allergic diseases.

Effects of class career psychological guidance on career planning abilities of college students / 中国心理卫生杂志

Objective:To explore the effects of class career psychological guidance(CCPG)on the career planning abilities of college students.Methods:By random sampling and control study methods,one class of college students were regarded as the experimental class of subjects,the other class was regarded as the control.The experimental class received 3 months of group training of CCPG,while the control class did not.They were assessed with the effect assessment scale of CCPG and the experimental class was retested 3.5 months later.Results:The overall level of career planning abilities had been improved in the experimental class after 3 months of CCPG,such as in the career planning confidence and the ability to solve problems relating to career,not in the control class. Most of the improved factors in the experimental class were still good after 3.5 months.Conclusion:The class career psychological guidance has a positive role in promoting the career planning abilities of college students.
