Decrease in skeletal muscle index one year after radical cystectomy as a prognostic indicator in patients with urothelial bladder cancer

ABSTRACT Purpose The present study aimed to determine whether sarcopenia after radical cystectomy (RC) could predict overall survival (OS) in patients with urothelial bladder cancer (UBC). Materials and Methods The lumbar skeletal muscle index (SMI) of 80 patients was measured before and 1 year after RC. The prognostic significance of sarcopenia and SMI decrease after RC were evaluated using Kaplan-Meier analysis and a multivariable Cox regression model. Results Of 80 patients, 26 (32.5%) experienced sarcopenia before RC, whereas 40 (50.0%) experienced sarcopenia after RC. The median SMI change was -2.2 cm2/m2. Patients with sarcopenia after RC had a higher pathological T stage and tumor grade than patients without sarcopenia. Furthermore, the overall mortality rate was significantly higher in patients with sarcopenia than in those without sarcopenia 1 year after RC. The median follow-up time was 46.2 months, during which 22 patients died. Kaplan-Meier estimates showed a significant difference in OS rates based on sarcopenia (P=0.012) and SMI decrease (P=0.025). Multivariable Cox regression analysis showed that SMI decrease (≥2.2 cm2/m2) was an independent predictor of OS (hazard ratio: 2.68, confidence interval: 1.007-7.719, P = 0.048). Conclusions The decrease in SMI after surgery might be a negative prognostic factor for OS in patients who underwent RC to treat UBC.

Laparoscopic Radical Cystectomy in the Elderly - Results of a Single Center LRC only Series

ABSTRACT Objective: To compare outcome of laparoscopic radical cystectomy (LRC) with ileal conduit in 22 elderly ( (≥75 years) versus 51 younger (<75 years) patients. patients. Materials and Methods: Analysis of prospectively gathered data of a single institution LRC only series was performed. Selection bias for LRC versus non-surgical treatments was assessed with data retrieved from the Netherlands Cancer Registry. Results: Median age difference between LRC groups was 9.0 years. (77.0 versus 68.0 years). Both groups had similar surgical indications, body mass index and gender distribution. Charlson Comorbidity Index score was 3 versus 4 in ≥50% of younger and elderly patients. Median operative time (340 versus 341 min) and estimated blood loss (<500 versus >500mL) did not differ between groups. Median total hospital stay was 12.0 versus 14.0 days for younger and elderly patients. Grade I-II 90-d complication rate was higher for elderly patients (68 versus 43%, p=0.05). Grade III-V 90-d complication rate was equal for both groups (23 versus 29%, p=0.557). 90-d mortality rate was higher for elderly patients (14 versus 4%, p=0.157). Median follow-up was 40.0 months for younger and 57.0 months for elderly patients. Estimated overall and cancer-specific survival at 5years. was 46% versus 35% and 64% versus 64% for younger and elderly patients respectively. Conclusions: Our results suggest that LRC is feasible in elderly patients, where a non-surgical treatment is usually favoured.

A comparison of preliminary oncologic outcome and postoperative complications between patients undergoing either open or robotic radical cystectomy

ABSTRACT Purpose: To compare complications and outcomes in patients undergoing either open radical cystectomy (ORC) or robotic-assisted radical cystectomy (RRC). Materials and Methods: We retrospectively identified patients that underwent ORC or RRC between 2003- 2013. We statistically compared preliminary oncologic outcomes of patients for each surgical modality. Results: 92 (43.2%) and 121 (56.8%) patients underwent ORC and RRC, respectively. While operative time was shorter for ORC patients (403 vs. 508 min; p<0.001), surgical blood loss and transfusion rates were significantly lower in RRC patients (p<0.001 and 0.006). Length of stay was not different between groups (p=0.221). There was no difference in the proportion of lymph node-positive patients between groups. However, RRC patients had a greater number of lymph nodes removed during surgery (18 vs. 11.5; p<0.001). There was no significant difference in the incidence of pre-existing comorbidities or in the Clavien distribution of complications between groups. ORC and RRC patients were followed for a median of 1.38 (0.55-2.7) and 1.40 (0.582.59) years, respectively (p=0.850). During this period, a lower proportion (22.3%) of RRC patients experienced disease recurrence vs. ORC patients (34.8%). However, there was no significant difference in time to recurrence between groups. While ORC was associated with a higher all-cause mortality rate (p=0.049), there was no significant difference in disease-free survival time between groups. Conclusions: ORC and RRC patients experience postoperative complications of similar rates and severity. However, RRC may offer indirect benefits via reduced surgical blood loss and need for transfusion.

Preoperative Underweight Patients with Upper Tract Urothelial Carcinoma Survive Less after Radical Nephroureterectomy

The prognostic impact of body mass index (BMI) in patients with upper tract urothelial carcinoma (UTUC) is an ongoing debate. Our study aimed to investigate the prognostic role of BMI in patients treated with radical nephroureterectomy (RNU) for UTUC from a multi-institutional Korean collaboration. We retrospectively reviewed data from 440 patients who underwent RNU for UTUC at four institutions in Korea. To avoid biasing the survival estimates, patients who had previous or concomitant muscle-invasive bladder tumors were excluded. BMI was categorized into approximate quartiles with the lowest quartile assigned to the reference group. Kaplan-Meier and multivariate Cox regression analyses were performed to assess the influence of BMI on survival. The lower quartile BMI group showed significantly increased overall mortality (OM) and cancer specific mortality (CSM) compared to the 25%-50% quartiles and upper quartile BMI groups. Kaplan-Meier estimates showed similar results. Based on multivariate Cox regression analysis, preoperative BMI as a continuous variable was an independent predictor for OM and CSM. In conclusion, preoperative underweight patients with UTUC in Korea survive less after RNU. Preoperative BMI may provide additional prognostic information to establish risk factors.

Análisis de supervivencia en pacientes sometidos a cistectomía radical por cáncer vesical en un Hospital docente-asistencial / Analysis of survival in patients undergoing radical cystectomy forbladder cancer in a teaching Hospital

Examinar factores pronósticos y analizar la supervivencia en pacientes sometidos a cistectomía radical (CR) por cáncer vesical. MATERIAL Y MÉTODO: estudio de cohortes retrospectivo de 46 pacientes sometidos a CR por cáncer vesical entre julio de 2003 y septiembre de 2012, considerándose como variable dependiente la supervivencia y como variables independientes: las características demográficas, comorbilidades, riesgo anestésico, condición clínica, lapso entre la RTU y la cistectomía, derivación urinaria utilizada, resultados anatomopatológicos y complicaciones postoperatorias. Se analizó la supervivencia mediante Kaplan-Meier, elaborando curvas que fueron comparadas mediante el método de Mantel-Cox. Se efectuó un análisis de supervivencia a 2 años de la cistectomía, mediante regresión logística binaria multivariante. RESULTADOS: La media de la supervivencia global fue 31,8 meses (mediana = 12 meses) y la de la específica 38,2 meses (mediana = 16). La supervivencia global fue mayor en enfermos menores de 70 años, con función renal o albuminemia normales, ASA <3 y en quienes se elaboró una neovejiga. La supervivencia específica fue mayor en los pacientes con estadio tumoral (pT) <3, densidad ganglionar <20 por ciento, margen quirúrgico negativo, sin compromiso ganglionar o masa residual (R0) y en los sometidos a linfadenectomía. Los factores de riesgo para fallecer dentro de los primeros 2 años fueron edad sobre 69 años, ASA >2, pT >2 (OR 25), compromiso ganglionar, metástasis a distancia, masa residual y margen positivo. CONCLUSION: La infiltración local, la afectación ganglionar y una edad mayor a 69 años fueron los tres factores de riesgo más determinantes de un peor pronóstico.

To review prognostic factors and analyze the survival of patients treated with radical cystectomy (RC) for bladder cancer. MATERIALS AND METHODS: Retrospective cohort study of 46 patients underwent RC for bladder cancer between July 2003 and September 2012 was carried out, considering survival as the dependent variable and as independent variables the following: demographic characteristics, comorbidities, anesthetic risk, clinical condition, delay between transurethral resection (TUR) and cystectomy, urinary diversion performed, pathologic findings, and postoperative complications. A survival analysis using the Kaplan-Meier method was performed; as a result curves were obtained and compared using the Mantel-Cox test. A multivariate binary logistic regression was performed, and prognostic factors of survival at 2 years of cystectomy were evaluated. RESULTS: The median overall survival was 31.8 months (median 12 months) and specific overall survival was 38.2 months (median = 16). Overall survival was higher in patients younger than 70 years, with normal renal function and normal albumin, ASA minor than 3 and in those that a neobladder was developed. Specific survival was higher in patients with tumor stage (pT) <3, node density <20 percent, negative surgical margins, without lymph node involvement or residual mass (R0) and in those underwent to lymphadenectomy. Risk factors for death within the first 2 years were: age over 69 years, ASA> 2, pT> 2 (OR 25), nodal involvement, distant metastases, residual mass and positive margins. CONCLUSIONS: Local infiltration, lymph node involvement and age over 69 years were the three most crucial risk factors for a worse prognosis.

Comparison of Radical Cystectomy with Conservative Treatment in Geriatric ( 80) Patients with Muscle-Invasive Bladder Cancer

Introduction The aim of this study was to compare overall survival in elderly patients (≥ 80 years) with muscle-invasive bladder cancer (MIBC) undergoing either radical cystectomy (RC) or conservative treatment. Material and Methods We performed a retrospective, comparative analysis of overall- and cancer-specific survival in octagenarians with MIBC (≥ pT2) submitted to RC or conservative treatment. Uni- and multivariable Cox regression analysis were performed to assess predictors of overall survival. Cumulative hospital stay was also analyzed for all patients. Results The RC-group consisted of 33 patients with a mean age of 82.3 years (IQR 80.4-85.4 years) and the bladder preservation a cohort of 35 patients aged 83.8 years (IQR 81.8-88.2 years). No difference was detectable for overall survival (15.9 months versus 9.5 months; p = 0.18) and cancer-specific survival (23.5 months versus 19.5 months p = 0.71) or 90-day mortality (6.1% versus 14.3%; p = 0.43) between the two groups. Patients who received conservative treatment had a shorter cumulative length of hospital stay (p = 0.001). Age at the time of transurethral resection of the bladder (TUR-B) was an independent predictor of the overall survival (p = 0.004). Conclusions In this retrospective study, no clear survival benefit was observed for patients ≥ 80 years submitted either to radical cystectomy or conservative treatment. There was however a trend favoring radical cystectomy but this did not approach statistical significance. Octagenarians that underwent RC however spent more of their remaining lifetime in the hospital than those treated conservatively. .

Analysis of the perioperative and five-year oncological outcome of two hundred cases of open radical cystectomy: A single center experience.

Objectives: We prospectively evaluated our perioperative and five-year oncological results of 200 cases of open radical cystectomy with urinary diversion, for formulating contemporary benchmarks, for future comparison of minimally invasive techniques. This is one of the largest prospective series reported from India of open radical cystectomy. Materials and Methods: Between 2004 and 2009, patients undergoing open radical cystectomy with urinary diversion, at our institution, were prospectively enrolled in the study. Data were recorded and analyzed statistically. Results: Two hundred patients were enrolled in the study. The mean age was 65.1 years. The patients undergoing ileal conduit and orthotopic neobladder were 159 (79.5%) and 41 (20.5%), respectively. The mean operating time was 275 minutes. The mean operating time for ileal conduit and orthotopic neobladder were 262 minutes and 288 minutes, respectively. The mean estimated blood loss was 690 ml. Blood transfusion was required in 37 (18.5%) patients. The mean hospital stay was 6.1 days. Major and minor complications were recorded in 16 (8%) and 31 (15.5%) patients, respectively. Perioperative mortality was recorded in only two (1.5%) patients. The pathologically organ-confined and non-organ-confined cases were 135 (67.5%) and 65 (32.5%), respectively. Thirty-three (16.5%) patients had pathologically confirmed lymph nodes. Median follow-up was 60.1 months. Local recurrence and distant metastases were recorded in 16 (8%) and nine (4.5%) patients, respectively. A five-year disease-free survival, cancer-specific survival, and overall survival were 75.5, 71.5, and 63.5%, respectively. Conclusions: Open radical cystectomy has an acceptable perioperative morbidity and mortality, along with a favorable five-year oncological efficacy. Minimally invasive techniques need a long-term prospective comparison with this approach, before being accepted as a standard treatment for urinary bladder malignancy.

Results from three municipal hospitals regarding radical cystectomy on elderly patients

OBJECTIVE: Radical cystectomy is the standard treatment for invasive bladder carcinoma in elderly patients at major surgical centers. As yet no data are available as to the question whether radical surgery on the genitourinary tract of patients over 75 can also be carried out at municipal hospitals with comparable intra and postoperative morbidity, and respective mortality. MATERIALS AND METHODS: 452 radical cystectomies and urinary diversions as ileum conduits or ileum neobladders due to transitional cell carcinoma were carried out at three municipal hospitals between 1992 and 2004. At the time of the surgery, 44 patients (9.7 percent) were > 75 (75-84) (Group-1), by comparison 408 patients were younger than 75 (35-74) (Group-2). Comparisons are to be made between the groups for 30 day mortality, 30 day reoperation rate, early complication rate (< 3 months), late complication rate (> 3 months), progression-free survival, and overall survival. The results are to be discussed in view of the international literature. Mean follow-up was 49 months (median: 38 months). RESULTS: The perioperative mortality in Group-1 was 2.3 percent compared to 2.5 percent in Group-2 (p = 0.942). There was no significant difference in the perioperative mortality with regard to the different case load of the evaluated hospital. There were no significant group differences regarding the 30 day reoperation rate, early and late complications. Progression-free and overall survival of all patients after 5 years was 56.1 percent and 53.6 percent respectively; here again the differences between the age groups was not significant (p = 0.384 and p = 0.210). Our results for patients > 75 do not differ from the published data of large clinics with a high cystectomy frequency. CONCLUSIONS: Our data confirm that radical cystectomy on elderly patients can also be carried out in municipal hospitals with acceptable mortality and morbidity rates. Of prime importance is a careful...
