ABSTRACT

Objective To explore the influencing factors of hyperlipidemia in 18-80 years old in Ningxia by structural equation model, and to analyze the direct and indirect effects of influencing factors of hyperlipidemia, so as to provide a basis for the formulation of prevention and treatment measures. Methods A total of 925 patients with hyperlipidemia from a chronic disease survey in 4 counties of Ningxia in April 2017 were selected as the case group (n=925), and residents without hyperlipidemia matched by sex and age were selected as the control group (n=925). A self-designed questionnaire was used to investigate the two groups of subjects. SPSS 22.0 software was used to conduct single factor T or Z test or χ2 test for the possible influencing factors of hyperlipidemia, and Amos22.0 was used to construct structural equation model. Results The structural equation model showed that physiological condition had the greatest effect on hyperlipidemia, and the standardized regression coefficient was -0.351. The second was the monitoring of three key blood indicators (three-high indicators), and the total effect value was 0.082, while personal condition and dietary status had no direct influence on the prevalence of hyperlipidemia. Conclusion Physiological status is the most important factor affecting the prevalence of hyperlipidemia in 18 ~ 80 years old in Ningxia, followed by the monitoring of the three-high indicators. In the future, residents should be encouraged to strengthen health management, especially people with overweight, high uric acid, high blood glucose and hypertension, to control the level of blood lipids and reduce the incidence of hyperlipidemia.

ABSTRACT

Objective:To analyze the radiotherapy-related factors affecting the survival of non-small cell lung cancer (NSCLC) patients complicated with malignant pleural effusion (MPE)(MPE-NSCLC).Methods:From 2007 to 2019, 256 patients pathologically diagnosed with MPE-NSCLC received primary treatment. Among them, 117 cases were enrolled in this study. All patients were divided into two groups according to the radiation dose (<63 Gy and≥63 Gy). Propensity score matching (PSM) was performed to further adjust the confounding factors (Calipers value=0.1). The impact of radiotherapy-related factors on the overall survival (OS) was analyzed by Kaplan—Meier method, log-rank test and Cox’s regression model. Results:Primary tumor radiotherapy significantly prolonged the OS ( P<0.001). The radiation dose escalation (36.0-44.1 Gy, 45.0-62.1 Gy, 63.0-71.1 Gy) of primary tumor significantly prolonged the OS ( P<0.001). The corresponding median OS were 5, 13 and 18 months, respectively. Before the PSM, univariate analysis suggested that radiation dose ≥63 Gy, gross tumor volume (GTV)<157.7 cm 3 and stations of metastatic lymph node (S-mlN)≤5 were significantly associated with better OS (all P<0.05) and T 4N 3 was significantly associated with worse OS ( P=0.018). After the PSM, univariate analysis indicated that radiation dose ≥63 Gy was significantly associated with better OS ( P=0.013) and S-mlN ≤5 had a tendency to prolong the OS ( P=0.098). Prior to the PSM, multivariate analysis showed that radiation dose ≥63 Gy was an independent favorable factor of OS ( HR=0.566, 95% CI 0.368-0.871, P=0.010) and GTV<157.7 cm 3 had a tendency to prolong the OS ( HR=0.679, 95% CI 0.450-1.024, P=0.065). After the PSM, multivariate analysis revealed that radiation dose ≥63 Gy was still an independent favorable factor of OS ( HR=0.547, 95% CI 0.333~0.899, P=0.017). No ≥grade 4 radiation toxicity occurred. The incidence rates of grade 3 radiation esophagitis and pneumonitis were 9.4% and 5.1%, respectively. Conclusion:For MPE-NSCLC, radiotherapy dose of primary tumor may play a key role in improving OS on the basis of controllable MPE.

ABSTRACT

Objective:To explore the changes of CD 8+ T cells in stage Ⅲ-Ⅳ non-small cell lung cancer (NSCLC) patients before and after radiochemotherapy and evaluate its clinical value in predicting survival. Methods:A total of 795 patients with stage Ⅲ-Ⅳ NSCLC who completed CD 8+ T cell testing from January 2011 to December 2017 were recruited (249 patients completed 1-3 tests within 6 months after treatment). The survival difference of patients with different levels of CD 8+ T cells and the prognostic value of the changes in the CD 8+ T cell level were analyzed. The survival analysis was performed by Kaplan- Meier method and log-rank test or univariate analysis. The multivariate survival analysis was conducted by Cox’s regression model. Results:Before treatment, the levels of CD 8+ T cells in the peripheral blood did not significantly differ among patients with different clinical factors. The survival time of stage Ⅲ NSCLC patients with CD 8+ T cell levels of<26.44% was significantly prolonged ( P=0.043). After treatment, the levels of CD 8+ T cells were significantly higher than those before treatment. The levels were similar within 1-3 months, decreased after 4-6 months but still significantly higher than those before treatment. The median survival time of patients with CD 8+ cell levels of<43.90% after treatment was 22 months, significantly longer than 16 months of those with CD 8+ cell levels of ≥43.90%( P=0.032). Stratified analysis demonstrated no significant difference in the survival time at 1 month and 2-3 months after treatment ( P>0.05), whereas the survival time significantly differed at 4-6 months ( P=0.001). The multivariate survival analysis showed that CD 8+ cell levels of<43.90% after treatment was an independent prognostic factor ( HR=0.714, P=0.031). Conclusions:The effect of CD 8+ T cells on prognosis of patients with stage Ⅲ-Ⅳ NSCLC is limited. After treatment, CD 8+ T cell levels are increased significantly. A certain increase in the CD 8+ T cell levels can prolong the survival time. The detection of CD 8+ T cell subtypes plays a more significant role.

ABSTRACT

Objective:To explore the possibility of CD 4+ T cells and CD 4+ /CD 8+ ratio in peripheral blood to predict the survival of patients with stage Ⅳ non-small cell lung cancer (NSCLC), and to establish a Nomogram prediction model. Methods:The influence of CD 4+ T cells and CD 4+ /CD 8+ ratio on the clinical factors and survival of 682 patients pathologically diagnosed with stage Ⅳ NSCLC with no history of cancer treatment was retrospectively analyzed and the Nomogram prediction model was established. Combined with the changes of immune cells levels in 110 patients after treatment, the prognostic and predictive values of CD 4+ T cells and CD 4+ /CD 8+ ratio were verified. Countable data were analyzed by t-test. The survival rate was calculated by Kaplan-Meier method, log-rank test or univariate analysis. The multivariate analysis was performed by Cox regression model. Results:Univariate analysis demonstrated that CD 4+ > 43.15% before treatment significantly prolonged the survival. By multivariate analysis of Cox regression model, CD 4+ >43.15% was an independent prognostic factor to prolong survival for stage Ⅳ NSCLC. The Nomogram model was established and verified that the predicted and actual overall survivals were highly consistent. Further analysis showed that 43.15% as the critical value of CD 4+ T cell level significantly prolonged survival when CD 4+ expressed at a high-level before treatment, after treatment, before and after treatment, or combined with CD 4+ /CD 8+ >1.65. Conclusions:The baseline level of CD 4+ T cells before treatment in peripheral blood is an independent prognostic factor for stage Ⅳ NSCLC. The CD 4+ /CD 8+ ratio before treatment has limited value in predicting the prognosis.

ABSTRACT

Objective:To retrospectively analyze the clinical efficacy and safety of three-dimensional radiotherapy for the primary tumors in patients with stage Ⅳ non-small cell lung cancer complicated with malignant pleural effusion (MPE-NSCLC).Methods:A total of 198 patients who were initially pathologically diagnosed with MPE-NSCLC from January 2007 to April 2018 were enrolled and divided into the untreated group ( n=45), drug group ( n=57) and radiotherapy group ( n=96), respectively. The short-term efficacy, overall survival (OS) and adverse events in the drug and radiotherapy groups were analyzed. The OS rate was analyzed by Kaplan-Meier method and log-rank test. Clinical prognosis was evaluated by multivariate Cox′s regression model. Results:In the radiotherapy group, the objective response rate and non-response rate was 54% and 46%, significantly better than 25% and 75% in the drug group ( P=0.007). In the radiotherapy group, the 1-, 2-, 3-, 5-year OS and median survival was 47%, 18%, 6%, 1% and 12 months, remarkably higher than 15%, 3%, 2%, 0% and 5 months in the drug group, respectively (all P<0.001). Multivariate Cox′s regression analysis showed that radiotherapy for the primary tumors was an independent prognostic factor to prolong the OS ( P<0.001). Radiotherapy at a dose of ≥63 Gy and 4-6 cycles of chemotherapy tended to prolong the OS ( P=0.063 and 0.071). The OS of patients with EGFR mutation receiving radiotherapy combined with molecular target therapy was significantly better than that of those with unknown EGFR status treated with radiotherapy and chemotherapy ( P=0.007). Addition of radiotherapy for the primary tumors did not significantly increase the incidence of adverse events ( P>0.05). Conclusion:Addition of three-dimensional radiotherapy for the primary tumors in MPE-NSCLC patients may prolong the OS and yield tolerable adverse events.

ABSTRACT

Objective To investigate the impact of the changes of posttreatment karnofsky performance status (KPSpost) on the overall survival (OS) for patients with stage Ⅳ non-small cell lung cancer (NSCLC) underwent concurrent chemoradiation.Methods A total of 279 patients (male 198 and female 81) with histological confirmed stage Ⅳ NSCLC were enrolled in this study with a median age of 58 years old (range 22 to 80 years old).There were 166 cases of squamous carcinoma,87 cases of adenocarcinoma,and 22 cases of unclassified carcinoma,respectively.All enrolled patients received more than 2 cycles of chemotherapy and more than 36 Gy of concurrent radiotherapy.Kaplan-Meier method and Log-rank test were applied to evaluate OS.Multivariate analyses were carried out by the Cox proportionalhazard model.Chi-square test and logistic regression analysis were used to explore the related factors of KPSpost.Results There were 198 patients with improved KPSpost and 81 patients with decreased KPSpost,respectively.Univariate and multivariate analyses indicated that the improvement of KPSpost was associated with longer OS.Logistic regression analysis showed that the improvement of KPSpost was positively related with treatment of more than 4-6 cycles chemotherapy concurrent with over 63 Gy radiation to primary tumor.The improvement of KPSpost also correlated positively with disease control rate (DCR),but negatively with PLT toxicity and radiation esophagitis.Conclusions KPSpost was an independent prognostic factor of OS for patients with stage Ⅳ NSCLC underwent concurrent chemoradiation.Chemotherapy of 4-6 cycles and concurrent over 63 Gy radiotherapy dose to primary tumor,as well as DCR were positive factors for KPSpost improvement.However,stage 3-4 PLT toxicities and radiation esophagitis decreased the KPSpost.

ABSTRACT

Objective To investigate the effect of flash glucose monitoring (FGM) on ambulatory glucose profile of only oral antidiabetic drugs treated patients with type 2 diabetes mellitus. Methods Twenty-eight type 2 diabetic mellitus patients with only oral antidiabetic drugs treatment from August 2017 to January 2018 were enrolled. All the patients were exposed to FGM for 14 d without changing the original treatment and encouraged to manage self-behavior by adjusting diet and activity based on the blood glucose data obtained from the real-time scanning. The changes in glucose profile during the FGM period were observed, including estimated glycated hemoglobin (HbA1c), standard deviation of blood glucose, variable coefficient of blood glucose, mean amplitude of glycemic excursions, time in range (blood glucose 3.9 to 10.0 mmol/L), area under the curve hyperglycemia (blood glucose> 10.0 mmol/L) and area under the curve hypoglycemia (blood glucose<3.9 mmol/L). The blood glucose levels on second day and thirteenth day were used as baseline and end point respectively. Results All of the 28 patients did not change their anti-diabetic drug therapy and there were no adverse events occurred. The estimated HbA1c was significantly lower than the baseline HbA1c: (6.90 ± 1.48)% vs. (7.57 ± 1.35)%, and there was statistical difference (P = 0.004). The standard deviation of blood glucose, variable coefficient of blood glucose, mean amplitude of glycemic excursions, area under the curve hyperglycemia and area under the curve hypoglycemia at end were significantly lower than those at baseline: (2.07 ± 0.86) mmol/L vs. (2.44 ± 0.86) mmol/L, 0.26 ± 0.11 vs. 0.30 ± 0.11, (5.32 ± 2.75) mmol/L vs. (6.76 ± 3.06) mmol/L, 265 (0, 1 310) vs. 351 (107, 2 177) and 0 (0, 0) vs. 0 (0, 19), the time in range at end was significantly higher than that at baseline: (1 069 ± 386) min vs. (921 ± 449) min, and there were statistical differences (P<0.05 or<0.01). The rate of scanning was (12.92 ± 4.87) times/d. Conclusions FGM could be applied by type 2 diabetic mellitus patients to make self-glycemic management without changing therapy, reduce the estimated HbA1c,and hypoglycemia, and improve the glucose fluctuations, which may result from real-time scanning to find abnormal glycemia and adjust daily behavior.

ABSTRACT

Objective To analyze the present situation of glucose metabolism and the characteristics of blood glucose fluctuation in in-hospital type l diabetic patients (T1DM). Methods One hundred and forty-three hospitalized cases of T1DM patients from November 2012 to November 2016 were retrospectively analyzed.The percentage of adult-onset T1DM patients was 76.22%(109/143)and none adult-onset was 23.78%(34/143). The following data were collected: general information, the indexes of glucose metabolism and islet function.Seventy-two-hour continuous glucose monitoring(CGM) was carried on 40 patients as a subgroup.Results The average age was(40.29 ± 16.79)years.The onset age of diabetes was(33.57 ± 17.18)years.The disease duration was 4.0(1.0,10.0)years.The body mass index(BMI)was(20.68 ± 2.95)kg/m2.The fasting blood glucose(FBG)was(12.02 ± 5.40)mmol/L.The HbA1c was(9.80 ± 2.65)%.The fasting C-peptide was 0.08(0.01,0.38)nmol/L.The 2-hour postprandial C-peptide (C-P 2 h) was 0.12(0.01, 0.70) nmol/L. The anti-glutamic acid decarboxylase antibody was 12.08(8.16,20.56)μg/L.The islet-cell antibody was 4.85(2.66,12.07)μg/L.By using multivariate linear regression analysis, HbA1c were negatively related to the duration and BMI of T1DM. CGM: the mean blood glucose was (10.34 ± 2.97) mmol/L. The standard deviation of blood glucose was (2.89 ± 1.07) mmol/L. The mean amplitude glycemic excursions was (7.10 ± 3.09) mmol/L. The incidence of hypoglycemia was 10.00% (≤ 2.8 mmol/L) and 32.50% (≤ 3.9 mmol/L). Conclusions Adult-onset T1DM patients account for more than two-thirds. In-hospital T1DM patients have poor control of blood glucose, and they show the clinical characteristics of high blood glucose fluctuation and more hypoglycemia.

ABSTRACT

Objective@#To investigate the optimal duration of pegylated-alpha interferon (Peg-INFα) combined with ribavirin (RBV) in treating chronic hepatitis C infection in human immunodeficiency virus (HIV)-infected patients.@*Methods@#A multicenter prospective study was conducted. The study subjects were divided into two groups; HIV/HCV co-infections (Group A, n = 158) and control with HCV-monoinfections (Group B, n = 60). All recruited patients received standard Peg-INFα plus RBV therapy. Group A was divided into 3 subgroups according to CD4+ cell counts: A1 subgroup, 79 cases, CD4+ counts > 350 cells /μl, who received anti-HCV before combination antiretroviral therapy(cART); A2 subgroup, 45 cases, CD4+ counts between 200 and 350 cells/μl, who did not start anti-HCV until they could tolerate cART well; A3 subgroup, 34 cases, CD4+ counts < 200 cells /μl, cART was administered first, and anti-HCV therapy was started when CD4+ counts > 200 cells/μl. The anti-HCV efficacy of two groups and 3 subgroups were compared. Statistical analysis for normal distribution and homogeneity of variance data was calculated by t-test and the counting data was analyzed by χ 2 test. The Mann-Whitney U test was used for non-normal data. A one-way analysis of variance (ANOVA) was used for the comparison of multiple groups, followed by SNK method. Multiple independent samples were used for non-parametric tests.@*Results@#There was no significant difference in age and baseline HCV RNA levels between groups and subgroups (P > 0.05). By an intent-to-treat (ITT) analysis, in Group A, the ratio of complete early virological response (cEVR) rate was 75.3% (119/158), the ratio of end of treatment virological response (eTVR) rate was 68.4% (108/158), and the ratio of sustained virological response (SVR) rate was 48.7% (77/158); in Group B, the ratio of cEVR rate was 93.3% (56/60), the ratio of eTVR rate was 90.0% (54/60), and the ratio of SVR rate was 71.7% (43/60); The therapeutic index of Group A were lower than those of Group B (P≤0.05). By per-protocol (PP) analysis, the ratio of cEVR rate in Group A [75.2% (88/112)] was still lower than that in Group B [93.3% (56/60)], but no significant differences were found in the ratio of eTVR rate and SVR rate between 2 groups (P > 0.05). Comparing the efficacy of subgroups (A1, A2 and A3) by ITT analysis, the ratios of cEVR rate were respectively 78.5% (62/79), 75.6% (34/45) and 67.6% (23/34); the ratios of eTVR rate were respectively 68.4%(54/79), 80.0%(36/45)and 52.9%(18/34); and the ratios of SVR rate were respectively 41.8%(33/79), 64.4%(29/45)and 44.1%(15/34). The ratio of eTVR in subgroup A2 was obviously higher than that in subgroup A3 and the ratio of SVR in subgroup A2 was statistically higher than that of subgroup A1(P≤0.05). However, by PP analysis, no significant differences of the therapeutic indexes were found among the respective subgroups (P > 0.05).@*Conclusion@#HIV-HCV co-infected patients would have better anti-HCV efficacy with Peg-INFα-2a plus RBV than HCV- monoinfected patients. The best time for initiating anti-HCV therapy in HIV-HCV co-infected patients is when CD4+ counts 200 cells/ μl.

ABSTRACT

Objective To investigate the subtypes distribution of human immunodeficiency virus (HIV)-1 epidemic strains and the characteristics of amino acid variation in different areas of Yunnan Province.Methods Totally 800 HIV/AIDS plasma specimens and epidemiological information were collected between 2012 and 2015 from 14 areas of Yunnan.Viral RNA was extracted and amplified using RT polymerase chain reaction (PCR).4.5 kb 5'halves fragments were obtained and directly sequenced.Subtypes of strains were identified by Genotyping,MEGA 6.06 and BLAST.Grouping was analyzed by location and subtype.Entropy software was used to analyze the difference of amino acid sequences between different groups according to the sampling location and subtypes to analyze the regional distribution and genetic variation of HIV-1 subtypes in Yunnan Province.Results Of the 800 plasma specimens,a total of 446 genomic sequences from 12 areas were successfully amplified and sequenced.After genotypes were identified,the subtypes of HIV-1 strains prevalent in Yunnan were CRF08_BC (58.3%),CRF01_AE (19.3%),CRF07_BC (11.6%),unknown recombinant forms (7.1%),B(B') (1.7%) and C (1.3%).The geographical distribution in Yunnan was analyzed.The CRF01_AE predominated in Dehong,Xishuangbarma and Wenshan.The CRF08_BC predominated in Lincang,Honghe and Puer (more than 70.0%) and CRF08_BC was prevalent in the other areas.But CRF07_BC in Kunming,Yuxi and Dali accounted for more than 20 %.The constitutions of amino acid of three majors CRF08_BC,CRF01 _AE and CRF07_BC were different on 17,14 and 18 amino acid sites with statistical differences in the eastern and western regions of Yunnan Province (均P < 0.05).Conclusions HIV-1 strains transmit and vary genetically in the province widely.The amino acid mutation sites of eastern and western strains are different.This difference represents that the same subtype strains in different geographical distribution vary on different genetic background and are selected by immune responses.The epidemic trends need to be closely monitored.

ABSTRACT

Objective To analyze the effect of long-term anti-viral treatment in children with acquired immune deficiency syndrome (AIDS) and investigate the factors affecting the treatment efficacy and growth and development of the children, so as to provide reference for improving the efficacy of antiviral drugs.Methods Children with AIDS receiving anti-retroviral treatment during 2004 to 2016 were retrospectively enrolled.The height, weight and CD4+ T cell counts were recorded every half year and the measurement of HIV RNA load was recorded on an annual basis.The CD4+ T cell counts and viral inhibition rates for the children who were under the treatment in the first year, 1~0.05);and viral inhibition rates were 92.9% and 97.6%, respectively with no statistical significance (χ2=1.071, P>0.05).The viral inhibition rate for the children receiving the treatment for 1 year was 85.7%, while that for whose treatment lasted for more than 10 years was 100.0%.A total of 5 cases developed drug-resistance (2 cases treated for 1 to 5 years and 3 cases for 5 to 10 years), and the virus replication was completely inhibited after switching to Lopinavir/ritonavir (LPV/r).The drug compliance was more than 95.0%.64.8% of children met the standard height, while 68.5% met the standard body mass.The baseline and last measured CD4+ T cell counts showed no significant differences between family-raised and social organization-raised children (Z=-1.159 and -0.523, respectively, both P>0.05).The children from high-income families had no significant differences compared with those from low-income ones in terms of the baseline and last measured CD4+ T cell counts (Z=-0.019 and -0.776, respectively, both P>0.05).Conclusions The long-term anti-retroviral treatment can effectively elevate the CD4+ T cell counts, inhibit viral replication and ensure drug compliance, which may promote the growth and development of children.However, approximately 30% children are still lower than the normal standards in terms of height and body mass.The drug-taking observer plays a central role on treatment effect.Most of the children′s family suffer from poor economic conditions.

ABSTRACT

Objective To retrospectively analyze the effect of three-dimensional radiotherapy on the survival of patients with stage Ⅳ squamous cell lung cancer.Methods Of the 101 patients collected from two prospective phase Ⅱ studies, 88 were part of the per-protocol set.All patients received platinum-doublet chemotherapy with concurrent radiation to the primary tumor.Primary endpoints were overall survival (OS) and progression-free survival (PFS).Survival was calculated using the Kaplan-Meier estimator, and univariate and multivariate analyses were performed using the log-rank test and Cox model, respectively.Results The 1-, 2-, 3-, and 5-year OS rates of the 88 patients were 42.2%, 13.6%, 8.7%, and 3.1%, respectively, and the median survival time (MST) was 10 months.The 1-, 2-, 3-, and 5-year OS and MST at PTV dose ≥63 Gy were 45.7%, 25.7%, 17.1%, 7.1%, and 11 months, respectively, whereas the 1-, 2-, 3-, and 5-year OS and MST at PTV dose<63 Gy were 39.6%, 4.5%, 2.8%, 0%, and 10 months, respectively (P=0.007).The median PFS at ≥63 Gy and<63 Gy were 9 months and 7 months, respectively (P=0.032).The 1-, 2-, 3-, and 5-year OS and PFS of patients who received 4 cycles of chemotherapy at a PTV dose of ≥63 Gy were 51.9%, 29.6%, 18.5%, 9.9%, and 9 months, respectively (P=0.001 and P=0.012), which were significantly prolonged compared with other treatment modalities.Multivariate analysis showed that PTV ≥63 Gy may be influence the OS of patients (P=0.080).Conclusions Three-dimensional radiotherapy can prolong the survival of patients with stage ⅠV squamous cell lung cancer, as demonstrated by the gradual improvement in OS and PFS following the increase in the intensity of concurrent chemotherapy and radiation therapy.A PTV dose of ≥63 Gy may be influence the OS.

ABSTRACT

Objective To investigate the impact of clinical factors on survival in patients receiving concurrent chemotherapy and three?dimensional radiotherapy ( 3DRT) for stage IV non?small cell lung cancer ( NSCLC) . Methods A total of 203 patients were enrolled in a prospective clincial study from 2008 to 2012, and among these patients, 178 patients were eligible for analysis of clinical factors. All patients were treated with platinum?based doublets chemotherapy, with a median number of chemotherapy cycles of 4( 2?6 cycles) and a median dose of 3DRT of 60?3 Gy (36?0?76?5 Gy).The Kaplan?Meier method was used to calculate overall survival ( OS) rates, the log?rank test was used to compare survival rates between groups, and the Cox regression model were used for multivariate analysis. Results The 1?, 2?, and 3?year overall survival rates were 56%, 16%, and 10%, respectively, and the median survival time was 13 months (95% CI=11?500?14?500). The univariate analysis showed that platelet count ≤221×109/L, neutrophil count ≤5.2×109/L, white blood cell count<7×109/L, and improvement in Karnofsky Performance Scale ( KPS) after treatment significantly prolonged OS ( P=0?000,0?022,0?003, and 0?029) , and metastasis to a single organ and hemoglobin≥120 g/L tended to prolong OS (P=0?058 and 0?075). The multivariate analysis showed that white blood cell count<7×109/L, platelet count ≤221×109/L, and improvement in KPS after treatment were beneficial to OS ( all P<0?05) . Conclusions White blood cell count and platelet count before treatment and KPS after treatment are prognostic factors for patients with stage IV NSCLC receiving concurrent chemotherapy and 3DRT.

ABSTRACT

Objective To investigate the efficacy and safety of three?dimensional radiotherapy (3DRT) with concurrent chemotherapy for stage IV non?small?cell lung cancer ( NSCLC). Methods A total of 198 eligible patients from 2008 to 2012 were enrolled as subjects. With an age ranging between 18 and 80 years and a Karnofsky Performance Status ( KPS) score of 70 or more, those patients had no contraindication for radiotherapy and chemotherapy, and were newly diagnosed with stage IV NSCLC confirmed by histology or cytology, as well as limited metastatic disease (≤3 organs). Survival rates and acute toxicities in those patients were evaluated. Results The 3?year follow?up rate was 98?? 5% and the 3?year sample size was 165. The median overall survival (OS) and progression?free survival (PFS) were 13?? 0 months (95% CI,11?? 7 ?14?? 3 months) and 9?? 0 months (95% CI,7?? 7 ?10?? 3 months), respectively, while the 1?, 2?, and 3?year OS rates were 53?? 5%, 15?? 8%, and 9?? 2%, respectively. Multivariate analysis showed that a primary tumor volume smaller than 134 cm3 , a stable or increased KPS score after treatment, and a radiation dose of 63 Gy or more were independent prognostic factors for longer survival time ( P=0?? 008;P= 0?? 010;P= 0?? 014). The incidence rates of grade 3?4 neutropenia, thrombocytopenia, anemia, grade 3 radiation esophagitis, and grade 3 radiation pneumonitis were 37?? 9%, 10?? 1%, 6?? 9%, 2?? 5%, and 6?? 6%, respectively. The main cause of death was distant metastasis, and only 10% of the patients died of recurrence alone. Conclusions 3DRT with concurrent chemotherapy achieves satisfactory treatment outcomes with tolerable toxicities for stage IV NSCLC. Primary tumor volume, change in the KPS score after treatment, and radiation dose are independent prognostic factors for OS.Clinical Trial Registry Chinese Clinical Reistry,registration number:ChiCTRC10001026.

ABSTRACT

Objective To evaluate the efficacy and safty of antiviral treatment for chronic hepatitis B ( CHB ) patients in second trimester of pregnancy.Methods Seventy-nine CHB patients in second trimester of pregnancy were collected from Hangzhou First People’ s Hospital and Xixi Hospital of Hangzhou during January 2010 to December 2013.Patients were divided into antiviral treatment group ( n=47) and the control group (n=32) according to their own wishes.Patients in antiviral treatment group were given lamivudine or telbivudine treatment plus hepatoprotective medication, while those in control group were only given hepatoprotective medication.All pregnant women were observed for 12 weeks after childbirth and the neonates were followed-up for 6 months after birth.The liver function, HBV DNA loads, HBV serological markers were measured;adverse effects during pregnancy, blocking rates of mother-to-child transmission and the growth of neonates were documented.t test or Chi-square test was used for statistical analysis.Results Alanine aminotransferase ( ALT) normalization rate and HBV DNA negative rate in antiviral treatment group before childbirth were 88.6%(39/44) and 84.1%(37/44) , while those in the control group were 60.0%(18/30) and 0 (χ2 =8.27 and 50.46, P0.05).No patient in antiviral treatment group terminated pregnancy due to abnormal liver function or adverse effect of drugs, while 2 out of 30 patients (6.7%) in the control group terminated the pregnancy, but the difference between two groups was not of statistical significance (χ2 =1.01, P >0.05).Mother-to-child transmission of HBV was successfully blocked in antiviral treatment group, while 3 cases (11.5%) in control group were failed (χ2 =5.19, P0.05).Conclusion Antiviral treatment can improve liver function, inhibit HBV replication and reduce the risk of mother-to-child transmission, and is safe for CHB patients in second trimester of pregnancy.

ABSTRACT

Objective To investigate the role of three-dimensional (3D) radiotherapy to the thoracic primary tumor in non-small cell lung cancer (NSCLC) patients with bone metastases during chemotherapy with concurrent 3D radiotherapy.Methods From 2003 to 2010,the clinical data of 95 stage Ⅳ NSCLC patients with bone metastases were collected.All patients received 3D radiotherapy to the thoracic primary tumor and at least 2 cycles of chemotherapy.Of the 95 patients,47 had only bone metastases,and 48 had metastases to bones and other organs.The Kaplan-Meier method was used to calculate overall survival (OS) rates.The log-rank test was used for survival difference analysis and univariate prognostic analysis.The Cox regression model was used for multivariate prognostic analysis.Results The follow-up rate was 95%.The 1-,2-,and 3-year OS rates were 44%,17%,and 9%,respectively.The univariate analysis showed that radiation dose to the planning target volume (PTV) of primary tumor of ≥ 63 Gy,response to treatment of primary tumor,and at least 4 cycles of chemotherapy were favorable prognostic factors for OS in all patients (P =0.001,0.037,and 0.009).Radiation dose to the PTV of primary tumor of ≥ 63 Gy remained the favorable prognostic factor for OS in patients with only bone metastases and those with metastases to bones and other organs (P =0.045 and 0.012).Among patients with only bone metastases,those with T1 + T2 primary tumors had longer OS than those with T3 + T4 primary tumors (P =0.048).The multivariate analysis showed that radiation dose to the PTV of primary tumor of ≥ 63 Gy and metastases to bones only were independent favorable prognostic factors for OS in all patients (P =0.036 and 0.035).Conclusions For NSCLC patients with bone metastases,3D radiotherapy to the thoracic primary tumor and its dose play an important role in improving OS during chemotherapy with concurrent 3D radiotherapy.
