ABSTRACT

Objetivos: Identificación de factores pronósticos de recurrencia y mortalidad cáncer-específica en pacientes con tumor de urotelio superior tratados con cirugía. Materiales y métodos: Análisis retrospectivo de pacientes con tumor de urotelio superior operados entre 1999 y 2011 en nuestro centro (139 pacientes). Se recogieron variables demográficas, clínicas, diagnósticas y patológicas, así como el tratamiento realizado, complicaciones y evolución. Análisis descriptivo mediante la prueba de chi cuadrado (X2 ) para variables categóricas y el test ANOVA (Analysis of Variance) para variables continuas. Análisis univariante y multivariante mediante modelo de riesgos proporcionales de Cox. La significación estadística se consideró con un valor de p<0,05. Todos los cálculos fueron realizados con el paquete estadístico IBM® SPSS® Statistics v-21. Resultados: En el análisis multivariante se identificaron como factores predictores independientes de recurrencia el crecimiento sólido tumoral (cociente de riesgo [hazard ratio, HR]=4,02; p<0,001) y el alto grado citológico (G3) (HR=3,42; p=0,01). La presencia de tumor vesical previo o concomitante (HR=1,84; p=0,07) presentó una tendencia a la significación. Se identificaron como factores predictores independientes de mortalidad cáncer-específica la presencia de tumor vesical previo o concomitante (HR=2,23; p=0,02), el crecimiento sólido tumoral (HR=2,73; p=0,008), la presencia de hidronefrosis (HR=2,46; p=0,02) y el estadío patológico avanzado pT3-pT4 (HR=2,74; p=0,01). Conclusiones: En nuestra serie, la existencia de tumor vesical previo o sincrónico, el crecimiento tumoral sólido y el alto grado citológico se comportaron como factores pronósticos de recurrencia. La hidronefrosis, el tumor vesical previo o sincrónico, el estadío pT3-4 y el crecimiento tumoral sólido se comportaron como factores pronósticos de mortalidad cáncer-específica. (AU)


Objectives: Identification of prognostic factors for recurrence and cancer-specific mortality in patients with upper urothelial tumor treated with surgery. Materials and methods: Retrospective analysis of patients with upper urothelial tumor operated between 1999 and 2011 in our center (139 patients). Demographic, clinical, diagnostic and pathological variables were collected, as well as the treatment performed, complications and evolution. Descriptive analysis using the chi-square test (X2 ) for categorical variables and the ANOVA (Analysis of Variance) test for continuous variables. Univariate and multivariate analysis using the Cox proportional hazards model. Statistical significance was considered with a value of p<0.05. All calculations were made with the statistical package IBM® SPSS® Statistics v-21. Results: In the multivariate analysis, solid tumor growth (hazard ratio, HR=4.02, p<0.001) and high cytological grade (G3) (HR=3, were identified as independent predictors of recurrence. 42, p=0.01). The presence of a previous or concomitant bladder tumor (HR=1.84, p= 0.07) presented a tendency towards significance. The presence of a previous or concomitant bladder tumor (HR=2.23, p=0.02), the solid tumor growth (HR=2.73, p=0.008), the presence of hydronephrosis (HR =2.46, p=0.02) and the advanced pathological stage pT3-pT4 (HR=2.74, p=0.01). Conclusions: In our series, the existence of previous or synchronic bladder tumor, solid tumor growth and high cytological grade behaved as prognostic factors of recurrence. Hydronephrosis, previous or synchronous bladder tumor, stage pT3-4 and solid tumor growth behaved as prognostic factors for cancer-specific mortality.(AU)

Objective To identify predictors of recurrence and cancer-specific mortality in patients with upper urinary tract carcinoma treated with surgery. Material and Methods Retrospective analysis of patients with upper urinary tract urothelial carcinoma getting surgery between 1999 and 2011 in our institution (139 patients). We collected demographic, clinical, pathological and diagnostic variables as well as the treatment performed, the occurred complications and the evolution. A descriptive analysis was performed using the Chi square test for categorical variables and the ANOVA test for continuous variables. We performed an univariate and multivariate analysis using a proportional Cox risks model. Statistical significance was considered when p < 0.05. All calculcations were performed with SPSS statistics v-21. Results In the multivariate analysis, the solid tumor growth (HR = 4.02; p < 0.001) and a high cytological grade (G3) (HR = 3.42; p = 0.01) were identified as independent predictors; the presence of previous or concomitant bladder tumor (HR = 1.84; p = 0.07) showed a trend to statistical significance. In the multivariate analysis, the presence of previous or concomitant bladder tumor (HR = 2.23; p = 0.02), the solid tumor growth (HR = 2.73; p = 0.008), the presence of hydronephrosis (HR = 2.46; p = 0.02) and the advanced pathological stage pT3-pT4 (HR = 2.74; p = 0.01) were identified as independent predictors of cancer-specific mortality. Conclusion The existence of previous or concomitant bladder cancer at the diagnosis of upper urinary tract carcinoma, solid growth pattern and high cytological grade (G3) were identified as independent predictors of recurrence in our series. The existence of hydronephrosis at diagnosis, prior or concomitant bladder tumor, pathologic stage pT3­4 and the solid growth pattern were identified as independent predictors of cancerspecific mortality.
