Objective:To develop the children′s postoperative health-related quality of life scale for thyroid cancer and to test its reliability and validity.Methods:The first draft of the scale was developed through literature search, focus group meetings, and a pre-survey, and 116 children (76 for testing and 40 for external validation) with thyroid cancer attending Beijing Children′s Hospital of Capital Medical University were selected to answer the scale, to screen and categorize the questions and to form the final scale with multiple dimensions.Results:The children′s postoperative health-related quality of life scale for thyroid cancer contained 5 dimensions and 29 questions. Exploratory factor analysis showed that the cumulative variance explained by the 5 factors was 64.343%. Confirmatory factor analysis showed correlations between the questions and dimensions of this scale, fair convergent validity for the scale, and good discriminant validity. The validity of the validity scale showed that there was a existing correlation between the questions and the validity scale of this scale. The item-dimension correlation coefficients showed that the questions in each dimension were well differentiated. The total Cronbach′s α coefficient of the scale was 0.930, the folded half reliability was 0.843, and retest reliabilities at 2 weeks, 1 month, and 3 months after the initial test were respectively 0.936, 0.922, and 0.910.Conclusion:The developed children′s postoperative health-related quality of life scale for thyroid cancer has good reliability and validity and can be used to assess the health-related quality of life of children after thyroid cancer surgery.

Objective To evaluate the effect of different doses of thoracic radiotherapy (TRT) upon the clinical prognosis of patients with extensive-stage (stage Ⅳ) small cell lung cancer (ES-SCLC) and establish a Nomogram prediction model.Methods Clinical data of 144 patients pathologically diagnosed with ES-SCLC undergoing TRT in Tianjin Medical University Cancer Hospital from month,2010 to month,2016 were retrospectively analyzed.Clinical characteristics,treatment data and responses were evaluated.A Nomogram was established by using Cox's proportional hazard regression model to predict the overall survival (OS).The prediction capability and accuracy were assessed by the concordance index (C-index) and a calibration curve between the model and verification groups.Results The median follow-up time was 31.9 months.The 2-year OS rate was 20.3％.The Nomogram model demonstrated that TRT dose,liver metastases,oligometastases/polymetastases,number of chemotherapy cycle and response to chemotherapy were significantly correlated with clinical prognosis.The calibration curve revealed that the predicted and actual OS were highly consistent.The C-index was calculated as 0.701.In the subgroup analyses,patients with high-dose TRT obtained significantly better OS than their counterparts with low-dose TRT.Conclusion The Nomogram prediction model based on different TRT doses can accurately predict the OS rate of ES-SCLC patients,which is an individualized model for predicting the survival probability.

Objective: To investigate the clinical significance of NS1-BP expression in patients with esophageal squamous cell carcinoma (ESCC), and to study the roles of NS1-BP in proliferation and apoptosis of ESCC cells. Methods: A total of 98 tumor tissues and 30 adjacent normal tissues from 98 ESCC patients were used as study group and control group, and these samples were collected in Sun Yat-Sen University Cancer Center between 2002 and 2008. In addition, 46 ESCC tissues which were collected in Cancer Institute and Hospital of Tianjin Medical University were used as validation group. Expression of mucosal NS1-BP was detected by immunohistochemistry. Kaplan-Meier curve and log-rank test were used to analyze the survival rate. Multivariate Cox proportional hazard model was used to analyze the prognostic factors. Furthermore, NS1-BP was over expressed or knocked down in ESCC cells by transient transfection. Protein levels of c-Myc were detected by western blot. Cell viability and apoptosis was analyzed by MTT assay and flow cytometry. Results: Among all of tested samples, NS1-BP were down-regulated in 9 out of 30 non-tumorous normal esophageal tissues (30.0%) and 85 out of 144 ESCC tissues (59.0%), respectively, showing a statistically significant difference (P=0.012). In the study group, three-year disease-free survival rate of NS1-BP high expression group (53.2%) was significantly higher than that of NS1-BP low expression group (27.6%; P=0.009). In the validation group, the three-year disease-free survival rates were 57.8% and 25.5% in NS1-BP high and low levels groups, respectively, showing a similar results (P=0.016). Importantly, multivariate analyses showed that low expression of NS1-BP was an independent predictor for chemoradiotherapy sensitivity and shorter disease-free survival time in ESCC patients(P<0.05 for all). Furthermore, overexpressed NS1-BP in TE-1 cells repressed c-Myc expression, inhibited cell proliferation and promoted apoptosis. In contrast, knockdown NS1-BP in KYSE510 cells induced c-Myc expression, increased cell proliferation and repressed apoptosis. Conclusions NS1-BP is an independent favorable prognostic factor in ESCC. It inhibits cell proliferation and enhances cell apoptosis via repressing c-Myc. Targeting NS1-BP may be a new therapeutic strategy for ESCC patients.

Objective To investigate the effect of the timing of radiotherapy on the prognosis of limited-stage small cell lung cancer (LS-SCLC) in the elderly. Methods A retrospective analysis was performed on the clinical data of 80 elderly patients with LS-SCLC who were treated with radical sequential thoracic chemoradiotherapy from 2008 to 2014.The correlations of SER(time from the start of any treatment to the end of radiotherapy) and the number of induction chemotherapy cycles with overall survival(OS) and progression-free survival (PFS) rates was analyzed. The treatment outcomes were compared between early radiotherapy group (no later than 3 cycles of induction chemotherapy,n=37) and late radiotherapy group (after 3 cycles of induction chemotherapy,n=43).The Kaplan-Meier method was used for survival analysis. Results In all patients,the median OS and PFS were 23.5 and 13.3 months respectively. SER was significantly correlated with OS and PFS (P=0.001;P=0.001).The median OS in patients undergoing radiotherapy after 2,3,4,5,and 6 cycles of induction chemotherapy was 33.2,26.7,20.6,16.9,and 17.9 months (P=0.000),respectively. The median OS time and 1-,2-,and 5-year OS rates were 27.8 months, 87%,62%,and 34%,respectively,in the early radiotherapy group,and 17.9 months,74%,37%,and 15%, respectively,in the late radiotherapy group (P=0.017).The median PFS time and 1-,2-,and 5-year PFS rates were 17.1 months,65%,43%,and 28%,respectively,in the early radiotherapy group,and 11.9 months,49%,21%,and 14%,respectively,in the late radiotherapy group( P= 0.022). Conclusions Shorter SER achieves better treatment outcomes in elderly patients with LS-SCLC undergoing sequential chemoradiotherapy. Early radiotherapy provides a survival benefit for patients.

Objective To investigate the effects of different metastatic sites on the prognosis of extensive?stage small cell lung cancer ( SCLC ) . Methods A retrospective analysis was performed among 322 patients pathologically or cytologically diagnosed with extensive?stage SCLC ( stage ⅠV defined by the seventh edition of the American Joint Committee on Cancer) who were admitted to our hospital from 2011 to 2015. In those patients, 246 had primary lesions with distant metastasis and 76 primary lesions with non?regional lymph node metastasis;261 had single?organ metastasis and 61 multi?organ metastases. Survival rates were calculated using the Kaplan?Meier method. Between?group comparison of the survival was made by the log?rank test. A multivariate prognostic analysis was made by the Cox proportional hazard model. Results In all the patients, the median survival time ( MST) was 11. 7 months;1?and 2?year overall survival ( OS) rates were 47. 9% and 19. 5%, respectively. The patients with single?organ metastasis had significantly longer MST and significantly higher 1?and 2?year OS rates than the patients with multi?organ metastases ( 12. 4 vs. 8. 9 months;52. 5% vs. 30. 5%;21. 9% vs. 11. 2%;P=0. 014) . In the patients with single?organ metastasis, those with liver metastasis had the worst prognosis with a MST of 8. 5 months, while those with non?regional lymph node metastasis had the best prognosis with a MST of 14. 5 months ( P= 0. 001 );there was no significant difference in the prognosis between patients with metastasis to different organs other than the liver ( P=0. 139) . In the patients with multi?organ metastases, those with liver metastasis and bone metastasis had the worst prognosis ( P=0. 016,0. 006);there was no significant relationship between brain metastasis and the prognosis of extensive?stage SCLC with multi?organ metastases ( P=0. 995) . There was no significantdifference in the prognosis between those with liver metastasis only and multi?organ metastases ( P=0. 862) . Conclusions Liver metastasis predicts the worst prognosis in patients initially diagnosed with extensive?stage SCLC and single?organ metastasis. Liver metastasis and bone metastasis predict the worst prognosis in patients with multi?organ metastases. Brain metastasis has no significant effect on the prognosis. There is no significant difference in the prognosis of extensive?stage SCLC between patients with single?and multi?organ metastases once liver metastasis occurs.
