RESUMO

Objective To summarize the relationship between metabolic syndrome (MS),its components and T1 stage with high grade urothelial carcinoma (HGUC) of the Bladder.Methods The clinical data of 200 patients with T1 high grade bladder cancer who were admitted to our hospital from January 2010 to June 2014 were retrospectively analyzed,including 155 males and 45 females.Ages were 24 to 86 years old,average 66 years old.Based on the history or blood glucose levels,patients were divided into diabetic group (n =41) (20.5%) and non diabetes group 159 cases (79.5%);According to the body mass index (BMI) were divided into obese group (≥25 kg / m2) of 98 cases (49.0%) and non obese group (< 25 kg / m2) of 102 cases (51.0%).According to the blood pressure level,71 cases (35.5%) were divided into hypertension group and 129 cases of non hypertension group (64.5%).MS and its components and the relationship between the recurrence and progress of bladder cancer were analyzed.The Kaplan Meier method was used to assess MS and its components division of tumor progression free survival (progress-free survival,PFS) and recurrence free survival (recurrence-free survival,RFS) influence.Cox regression model of multi factor analysis were used to evaluate the PFS and RFs of MS and its components with bladder cancer.Results Of the 200 cases,16 cases (8.0%) were MS.Tumor recurrence occurred in 121 cases (60.5%),and 84 patients (42.0%) were in progress.Diabetes and non diabetes groups the average RFs were 21.7 and 29.3 months respectively,and the difference was statistically significant (x2 =10.115,P =0.001);The median PFS were 32.8 and 39.8 months respectively,the difference has statistical significance (x2 =14.760,P <0.001).Obese group and non obese group average RFs were 34.7 and 42.0 months respectively,and the difference were statistically significant (x2 =16.077,P < 0.001);The median PFS were 22.8 and 32.6 months respectively,the difference was statistically significant (x2 =16.174,P<0.001).The average RFS of MS group and non MS group were 21.5 and 28.4 months respectively,the difference was statistically significant (x2 =5.429,P =0.02);the average PFS was 35.1 and 38.7 months respectively,and the difference was statistically significant (x2 =3.854,P < 0.05).Cox multivariate survival analysis showed that diabetes and obesity can increase the risk of recurrence and progression of T1 advanced stage bladder cancer (HR =1.792,P =0.013,HR =2.498,P < 0.001;HR =0.559,P < 0.001;HR =0.492,P < 0.001).Conclusions Diabetes mellitus and obesity are high risk factors for the recurrence and progression of T1 advanced stage bladder cancer,but MS is not related to the prognosis of T1 patients with advanced bladder cancer.

RESUMO

Objective To evaluate the relationship between metabolic syndrome , its components and the histopathological findings in bladder cancer patients .Methods The data of 326 patients in our department between October 2010 and October 2013 were retrospectively analyzed.Age, gender, stature, weight, histologic stage, grade, and the presence of hypertension , diabetes mellitus, body mass index ( BMI) were evaluated.There were 64 females, 262 males, aged 23-89 years, including 241 low stage, 85 high stage, 155 low grade, and 171 high grade, respectively.There were 117 cases with hypertension, 95 cases with diabetes mellitus , 139 cases with BMI ≥25 kg/m2 and 49 cases with metabolic syndrome.The TNM classification was used , with Ta and T1 tumor accepted as low stage , T2 , T3 and T4 tumor as high stage bladder cancer.In addition, the pathological grading system adopted by the 2004 World Health Organization was applied.Non-invasive papillary urothelial neoplasms of low malignant potential were regarded as low grade.Analyses were completed using Chi-square tests to evaluate the correlation of diabetes mellitus , hypertension and obesity with the pathologic stage and grade .Moreover , the pathologic stage , grade and recurrence were compared between metabolic syndrome and non-metabolic syndrome groups . Results Metabolic syndrome was significantly associated with histological grade and stage (P=0.001, P=0.011). Diabetes mellitus and obesity were also associated with histological grade and stage (P=0.006, P<0.01). Conclusions Patients with metabolic syndrome were found to have significant higher T stage and grade of bladder cancer .Diabetes mellitus and obesity may promote the grading and staging of bladder cancer .

RESUMO

Objective To investigate the clinicopathological features, treatment modalities, and prognostic factors for survival in patients with urinary tract small cell carcinoma (UT-SCC).Methods A total of 25 patients treated from June 2000 to December 2014 were included in the retrospective study.The data included age, gender, primary tumors origins, stage, treatment modalities, progression-free survival (PFS), overall survival (OS), pathology and immunohistochemistry.Of these cases, 22 were male, and the other was female, whose age was 45-79 years (mean age 67).20 cases small cell carcinoma of bladder patients and 2 small cell carcinoma of prostate cancer patients were included.The number of small cell carcinoma in pelvis,ureter and retroperitoneal was 1 respectively.The patients with small cell carcinoma of the urinary tract were classified as disease and extensive disease.17 bladder small cell carcinomas were limited disease and 3 cases were extensive disease;Prostate small cell carcinomas were both extensive disease;The small cell carcinomas in pelvis, ureter were limited disease;The small cell carcinoma in retroperitoneal was extensive disease.10 bladder small cell carcinomas which were limited disease received radical cystectomy.6 of 10 patients received etoposide and cisplatnum (EC).4 of 10 patients received gemcitabine and cisplatnum (GC).7 bladder small cell carcinomas patients who with limited disease refused to receive radical cystectomy in which 2 patients received TURBT and 5 patients received TURBT followed chemotherapy.Both prostate small cell carcinomas received chemoradiotherapy.2 small cell carcinomas in upper urinary tract (pelvis and ureter) received radical nephroureterectomy with bladder cuff resection.The patient of retroperitoneal small cell carcinoma received percutaneous nephrostomy after biopsy.The progression-free survival (PFS) and overall survival (OS) of these patients are analyzed;the influence of TURBT with adjuvant chemotherapy and clinicopathologic characteristics were analyzed in median PFS and OS.PFS and OS were compared between groups as a function of time, using a Kaplan-Meier survival curve analysis and the log-rank significance test.All statistical tests were two-sided, and P values < 0.05 were considered statistically significant.Results 25 patients with a pathologic confirmation of UT-SCC,either by biopsy or surgery,were finally included.These patients were classified as pure UT-SCC (14) and Mixed UT-SCC (11).Mixed UT-SCC was defined as tumors containing both SCC and non-SCC components,regardless of the proportion of the latter.13 cases were strongly positive and 3 cases were weakly positive in neuron specific enolase (NSE) level.8 cases were strongly positive and 2 cases were weakly positive in CgA level.Patients with limited disease experienced a significant longer PFS and OS compared with extensive disease subjects (PFS 13.2 vs.7.8 x2=13.53 P<0.01;OS27.2 vs.12.7x2=19.88 P<0.01).Patients with bladder SCC showed a significantly higher median PFS and OS compared with patients with SCC of other parts of urinary tract (PFS 12.8 vs.8.2 x2 =12.00, P =0.001;OS 26.3 vs.13.2 x2 =14.45,P <0.01) .The two different chemotherapy regimens (GC and EC) have no influence on survival (PFS: 16.3 vs.12.5,x2 =3.34, P =0.07;OS 29.5 vs.22.8, x2 =1.66, P =0.198).TURBT followed by adjuvant therapy have no influence on survival (PFS 14.5 vs.12.0 t =1.30 P =0.251;OS 24.5 vs.28.4 t =0.50,P =0.636).Conclusions The primary tumors origins and stage may have influence on survival in patients with UT-SCC.Patients with bladder small cell carcinoma and limited disease experienced a longer survival.

RESUMO

Objective To analyze the diagnosis,treatment and prognosis of small cell carcinoma of bladder (SCCB) in order to improve the understanding of it.Methods The pathological and clinical data of 5 cases of SCCB were retrospectively analyzed.All patients were male,aged 50 to 78 years (mean age,64 years).Clinical manifestations of 4 cases were gross hematuria,the other case was found by health examination.Ultrasonography results of 3 cases were medium echo tumors,the other 2 cases were hypoecho tumors.The diameter of the tumor was 2.1 to 4.0 cm (mean,3.0 cm).There were 3 patients accepted CT scan.One of them was found of hydronephrosis and multiple pelvic lymph nodes.All patients accepted diagnostic TURBT.Three of them accepted postoperative chemotherapy (1 cycle) without other surgery.Two patients accepted radical cystectomy with postoperative chemotherapy (3 cycles) after bladder tumor biopsy.Results Pathological findings showed that tumor cells were small,round and sheet in arrangement.These hyperchromatic nuclei showed limited cytoplasm with lack of nesting character.Neuron specific enolase,chromogranin A and synaptophysin were positive in immunohistochemistry.The final diagnosis was SCCB'.Two of the three patients who accepted TURBT with postoperative chemotherapy died 7 and 8 months postoperatively,the other one was alive for 32 months.Another two patients who accepted radical cystectomy with postoperative chemotherapy were alive for 16 and 26 months.Conclusions SCCB is a rare tumor which has high malignancy and poor prognosis.Radical cystectomy in combination with postoperative chemotherapy is the main treatment.Retained bladder surgery with chemotherapy is an alternative choice.
