China Oncology 2000;0(06):-
Background and purpose:Radical cystectomy is viewed as the standard treatment for bladder carcinoma,but organ preservation has been attempted for patients with muscle-invasive bladder carcinoma over the past decades as an alternative to radical cystectomy.The majority of studies included transurethral resection of bladder tumor(TURB),radiotherapy,and chemotherapy,as a feasible and safe organ-sparing approach with the similar outcome to radical cystectomy.The current study evaluated the outcomes and complications of the radiation therapy for the patients with bladder cancer,and prognosis factors had been analyzed.Methods:We retrospectively analyzed 21 patients with bladder cancer.The clinical stages of the patients were 15 with T_2;5 with T_3 and 2 with T_4.2 of them were lymph node-positive,16 of patients were pathologically proved as transitional cell carcinoma,4 as adenocarcinoma and 1 as transitional cell carcinoma plus squamous cell carcinoma.Conventional fractionation radiotherapy was given at a median dose of 54.5Gy(ranged 49.2-69.9 Gy) after surgery.Kaplan-Meier method and Logrank method were used for the statistical analysis.Results:Median follow-up was 32 months.The overall survivals at 1 year,3 years and 5 years were 90.5%,47.1%,and 36.7% respectively.The local disease free rates were 95.0%,62.4%,and 47.5% respectively.15 of 16 patients' deaths were related to the tumor.In univariate analysis,only small field irradiation was found as a prognosis factor in survival(?~(2)=5.36,P=0.02).Conclusions:Combined treatment appears to provide high response rates and can be offered as an alternative option to radical cystectomy for selected patients who refuse or are unsuitable for surgery.A large number of patients,multicenter,prospective randomized trial would be desirable to evaluate the role of radiotherapy in the multi-modality treatment of bladder cancer.

Therapies for malignant glioma include surgery,radiotherapy and chemotherapy.In recent years,the overall effective rate of temozolomide is better than other chemotherapy drugs,but partly patients have resistance to temozolomide.Angiogenesis inhibitors show promising activity,but it is expensive.Celecoxib has antiangiogenic activity,which has become a new option.
6.Postoperative radiotherapy and chemotherapy in cervical cancer
Journal of International Oncology 2012;39(8):622-625
Local recurrence is more frequent in postoperative cervical cancer patients with high-risk factors.It is confirmed that adjuvant pelvic radiotherapy (RT) for the cervical cancer patients after surgery with high-risk factors can improve local control but can't improve the overall survival.Researches show that concurrent chemo-radiotherapy (CCRT) can improve survival rates compared with radiotherapy,but the adverse effects such as leucopenia and gastrointestinal toxicity are observed frequently.Intensity-modulated radiation therapy (IMRT) has been developed to deliver a high radiation dose to an irregular target volume,with relative sparing of adjacent normal tissues.IMRT has excellent local tumor control and overall survival.

Objective To investigate the clinical efficacy of the laparoscopic Roux-en-Y gastric bypass (LRYGB) and metformin in the treatment of obese patients with type 2 diabetes mellitus,and influencing factors of remission rate of diabetes.Methods The case-control study was conducted.The clinical data of 172 obese patients with type 2 diabetes mellitus who were admitted to the First People's Hospital of Shangqiu (43 patients) and the First Affiliated Hospital of Sun Yat-sen University (129 patients) from June 2010 to June 2015 were collected.Of 172 patients,82 undergoing LRYGB were allocated into the group A and 90 taking oral metformin were allocated into the group B.Observation indicators:(1) follow-up situations;(2) comparison of metabolic indices after treatment between the 2 groups;(3) influencing factors analysis of remission rate of diabetes in patients undergoing LRYGB;(4) influencing factors analysis of remission rate of diabetes in patients taking oral metformin.Follow-up using outpatient examination and telephone interview was performed to detect occurrence of treatment-related complications up to January 2017,and metabolic indices were measured regularly.Measurement data with normal distribution were represented as ±s and comparison between groups was analyzed using the independent-sample t test.Repeated measurement data were analyzed by the repeated measures ANOVA.Comparisons of count data were evaluated by the chi-square test.The univariate analysis and multivariate analysis were respectively done using the chi-square test and Logistic regression model.Results (1) Follow-up situations:172 patients were followed up after treatment for 19-43 months,with a median time of 28 months.During the follow-up,5 patients complicated with mild diarrhea and 1 complicated with iron deficiency anemia at 1 year postoperatively were improved by symptomatic treatment in the group A,and there was no treatment-related complications in the group B.(2) Comparison of metabolic indices after treatment between 2 groups:body mass,BMI,2-hour postprandial blood glucose (2HPBG),2-hour postprandial serum C-peptide,glycosylated hemoglobin (GHb),fasting insulin,2-hour postprandial insulin (2HPI),low-density lipoprotein (LDL) and cases with hypertension in the group A were (89±6) kg,(31.5±2.0) kg/m2,(19.4±3.9) mmol/L,(3.52± 0.32) μg/L,15.7% ±5.3%,(8.0± 1.4) uIU/L,(20.6± 2.5) uIU/L,(3.7 ± 1.3) mmol/L,24 before LRYGB and(77±16)kg,(24.2±2.9)kg/m2,(10.6±2.6) mmol/L,(7.19± 2.23) μg/L,5.3%±4.5%,(9.2± 4.3)uIU/L,(28.3±2.9)uIU/L,(2.2±2.1)mmol/L,9 after LRYGB,respectively,with statistically significant differences between preoperative and postoperative indicators (F=2.112,3.026,1.253,2.107,1.257,3.473,1.223,2.584,x2 =8.540,P < 0.05).Fasting blood glucose,2HPBG,fasting serum C-peptide,2-hour postprandial serum C-peptide,GHb,fasting insulin and 2HPI in the group B were (11.3±2.5)mmol/L,(18.5± 4.4) mmol/L,(1.54±0.33) μg/L,(3.57±0.91) μg/L,17.5% ±8.0%,(8.2± 1.3) uIU/L,(21.2±2.6) uIU/L before taking oral metformin and (6.6 ± 1.1) mmol/L,(10.2 ± 2.8) mmol/L,(3.52 ± 1.34) μg/L,(7.68 ± 1.94) μg/L,5.4% ±2.1%,(9.6± 3.9) uIU/L,(30.3± 3.1) uIU/L after taking oral metformin,respectively,with statistically significant differences between before and after taking oral metformin (F=1.245,3.224,3.127,2.064,3.672,2.074,1.137,P<0.05).Remission rate of diabetes and excess weight loss (EWL) in patients after treatment were 14.6%,80% ± 15% in the group A and 11.1%,60% ± 10% in the group B,respectively.There were statistically significant differences in body mass,BMI and EWL after treatment between the 2 groups (t=1.973,2.326,2.347,P<0.05),and no statistically significant difference in remission rate of diabetes between the 2 groups (x2 =0.477,P>0.05).(3) Influencing factors analysis of remission rate of diabetes in patients undergoing LRYGB:the results of univariate analysis showed that BMI,diabetes duration and LDL were factors affecting remission rate of diabetes in patients undergoing LRYGB,with statistically significant differences (x2=11.267,9.519,5.567,P<0.05).The results of multivariate analysis showed that diabetes duration < 10 years was an independent factor affecting good remission rate of diabetes in patients undergoing LRYGB,with statistically significant differences [OR=2.202,95% confidence interval (CI):1.418-3.420,P<0.05].(4) Influencing factors analysis of remission rate of diabetes in patients taking oral metformin:the results of univariate analysis showed that diabetes duration,GHb and LDL were factors affecting remission rate of diabetes in patients taking oral metformin,with statistically significant differences (x2 =6.306,7.758,4.652,P<0.05).The results of multivariate analysis showed that GHb < 15.0% was an independent factor affecting good remission rate of diabetes in patients taking oral metformin,with statistically significant differences (OR=3.167,95%CI:1.586-6.325,P<0.05).Conclusions LRYGB and oral metformin in the treatment of obese patients with type 2 diabetes mellitus are safe and effective,showing an equivalent remission rate of diabetes,and LRYGB had an advantage of weight loss.Diabetes duration < 10 years and GHb < 15.0% are respectively independent factors affecting good remission rate of diabetes in patients undergoing LRYGB and taking oral metformin.
