ABSTRACT
Introducción y objetivos: Análisis comparativo de complicaciones postoperatorias y supervivencia entre nefrectomía parcial (NP) y radical (NR) laparoscópica en cáncer de células renales (CCR) cT1.Material y método: Estudio retrospectivo de pacientes birrenos con tumor renal único cT1 tratados en nuestro centro entre los años 2005 y 2018 mediante NP o NR laparoscópica.Resultados: Cumplieron los criterios de inclusión para el estudio 372 pacientes. Fueron tratados mediante NR 156 (41,9%) y 216 (58,1%) mediante NP. En 10 (4,6%) NP y 6 (3,9%) NR hubo complicaciones Clavien Dindo III-V (p = 0,75). El índice de comorbilidad de Charlson (ICC) se identificó como variable predictora independiente de complicaciones (p = 0,02), no influyendo el tipo de cirugía en el análisis multivariante. La estimación de la supervivencia global (SG) fue de 81,2 y de 56,8% a los 5 y 10 años en el grupo de NR y de 90,2 y 75,7% en el grupo de NP, respectivamente (p = 0,0001). Se identificaron como factores predictores de mortalidad global la obesidad (HR 2,77, p = 0,01), el ICC ≥ 3 (HR 3,69, p = 0,001) y el FG<60 mL/min/1,73 m2 al alta (HR 1,87,p = 0,03). El tipo de nefrectomía no demostró influencia en la SG. La estimación de la supervivencia libre de recidiva (SLR) fue de 86,1% a los 5 y 10 años en el grupo de NR y de 93,5 y 83,6% en el grupo de NP respectivamente (p = 0,22).Conclusiones: La NP laparoscópica no es inferior a la NR en términos de seguridad oncológica y quirúrgica en el CCR cT1. El tipo de nefrectomía no influyó en la SG del paciente, sin embargo, sí se comportaron como factores predictores la obesidad, el índice Charlson ≥ 3 y el FG<60 mL/min/1,73 m2 al alta (AU)
Introduction and objectives: Comparative analysis of postoperative complications and survival between laparoscopic partial nephrectomy (PN) and radical nephrectomy (RN) in cT1 renal cell carcinoma (RCC).Material and method: Retrospective study of patients with two kidneys and single renal tumor cT1 treated in our center between 2005 and 2018 by laparoscopic PN or RN.Results: 372 patients met the inclusion criteria for the study. RN was performed in 156 (41.9%) patients and PN in 216 (58.1%). Clavien Dindo III-V complications were observed in 10 (4,6%) PN and 6 (3,9%) RN patients (p = 0.75). The comorbidity Charlson index (CCI) was identified as an independent predictor variable of complications (p = 0.02) and surgical approach did not affect multivariate analysis. Estimated overall survival (OS) was 81.2% and 56.8% at 5 and 10 years in the RN group and 90.2% and 75.7% in the PN group, respectively (p = 0.0001). Obesity (HR 2.77, p = 0.01), CCI ≥ 3 (HR 3.69, p = 0.001) and glomerular filtration rate (GFR) < 60 mL/min/1.73m2 at discharge (HR 1.87, p = 0.03) were identified as predictors of overall mortality. Nephrectomy approach showed no influence on OS. Estimated recurrence-free survival (RFS) was 86.1% at 5 and 10 years in the RN group and 93.5% and 83.6% in the PN group, respectively (p = 0.22).Conclusions: Laparoscopic PN is not inferior to RN in terms of oncologic and surgical safety in cT1 RCC. Nephrectomy approach did not influence patient OS, however, obesity, CCI ≥ 3 and GFR<60 mL/min/1.73m2 at discharge did behave as predictors (AU)

Introducción y objetivos Analizar la evolución de la función renal tras nefrectomía parcial (NP) y radical (NR) laparoscópica e identificar factores predictores de deterioro de función renal.Material y método Estudio retrospectivo de pacientes birrenos con filtrado glomerular (FG) > 60 mL/min/1,73 m2 y tumor renal único cT1 tratados en nuestro centro entre los años 2005 y 2018.Resultados 372 pacientes cumplieron los criterios de inclusión para el estudio. 156 (41,9%) fueron tratados mediante NR y 216 (58,1%) mediante NP. Al alta hubo una diferencia de 26,75 mL/min/1,73 m2 de FG entre NR y NP. La edad > 60 años, las complicaciones postoperatorias (OR 2,97, p = 0,005) y NR (OR 10,03, p = 0,0001) fueron factores predictores de FG<60 mL/min/1,73 m2 al alta. Únicamente la NR (OR 7,69, p = 0,0001) se comportó como factor pronóstico independiente de FG<45 mL/min/1,73 m2 al alta. La mediana de seguimiento de la serie fue de 57 (IQR 28 - 100) meses. Al final del seguimiento, nueve (6%) pacientes tratados con NR desarrollaron enfermedad renal crónica (ERC) grave y tres (2%) insuficiencia renal terminal (IRT). Edad > 70 años, diabetes mellitus (DM) (HR 2,12, p = 0,001), hipertensión arterial (HTA) (HR 1,73, p = 0,01) y NR (HR 2,88, p = 0,0001) se comportaron como factores predictores independientes de FG<60 mL/min/1,73 m2. Para un FG<45 mL/min/1,73 m2 fueron edad > 70 años, DM (HR 1,99 IC 95% 1,04 a 3,83, p = 0,04) y NR (HR 5,88 IC 95% 2,57 a 13,45, p = 0,0001).Conclusiones La NR es un factor de riesgo a corto y largo plazo de ERC, aunque con baja probabilidad de ERC grave o IRT en pacientes con FG > 60 mL/min/1,73 m2 preoperatoria. La edad, DM e HTA contribuyen al empeoramiento de la función renal durante el seguimiento (AU)

Age > 70 years, diabetes mellitus (DM) (HR 2.12, p = 0.001), arterial hypertension (AHT) (HR 1.73, p = 0.01) and RN (HR 2.88, p = 0.0001) behaved as independent predictors of GFR<60 mL/min/1.73 m2. The independent predictors for GFR< 45 mL/min/1.73m2 were age >70 years, DM (HR 1.99 CI 95% 1.04-3.83, p = 0.04) and RN (HR 5.88 CI 95% 2.57-13.45, p = 0.0001).Conclusions RN is a short- and long-term risk factor for CKD, although with a low probability of severe CKD or ESRD in patients with preoperative GFR > 60 mL/min/1.73 m2. Age, DM and AHT contribute to worsening renal function during follow-up (AU)
