Resumen
Objetivo

Se analizan 267 pacientes intervenidos quirúrgicamente de carcinoma renal, comparando el tumor incidental y el sintomático en relación a diversos parámetros, y valorando la significación pronóstica del diagnóstico incidental

Material y método

De los 267 pacientes, 110 (41,2%) fueron diagnosticados de forma incidental. Las variables analizadas fueron edad, sexo, tamaño tumoral, lateralidad, tipo histológico, estadio, grado de diferenciación celular y supervivencia

La media de seguimiento ha sido de 43,32 meses en los sintomáticos y 41,85 meses en los incidentales. Los datos obtenidos fueron analizados mediante el paquete estadístico SPSS

Resultados

No se ha encontrado diferencia significativa entre los dos grupos en relación a la edad, sexo, lateralidad o tipo histológico

Comparando el tamaño tumoral, se encontró diferencia estadísticamente significativa situando el punto de corte en 6 cm

Al analizar el estadio y grado de diferenciación celular, existe una diferencia significativa, resultando los tumores incidentales mejor diferenciados y en menor estadio al diagnóstico

La supervivencia a los cinco años ha sido del 65,7% en los sintomáticos frente al 81,7% de los incidentales, lo que supone una alta significación estadística (log rank = 0,0018)

Conclusiones

En nuestra serie, no existe diferencia significativa entre tumores incidentales y sintomáticos al comparar la edad, sexo, lateralidad y tipo histológico. Sí existe en relación al tamaño, grado de diferenciación celular, estadio tumoral y supervivencia

Abstract
Objetive

We present 267 patients undergoing surgery for renal carcinoma, comparing the incidental tumour and symptomatic tumour with different parameters and evaluating the prognostic significance of the incidental diagnosis

Material and method

Of the 267 patients, 110 (41.2 %) were diagnosed incidentally. The different variables analysed were: age, sex, tumour size, if unilateral or bilateral, histological type, stage, degree of cellular differentiation and survival

The mean follow-up period was of 43.32 mos in the symptomatic patients and 41.85 mos in the patients diagnosed incidentally. The data obtained was analysed with the SPSS statistic pack

Results

No significant difference was detected between both groups in regards to age, sex, if unilateral or bilateral and histological type

Comparing tumour size, a statistic difference was observed with slices at 6 cm

When analysing the stage and degree of cellular differentiation, a significant difference is found with tumours diagnosed incidentally presenting better differentiation and a lower stage at the moment of diagnosis

Survival after 5 yrs was of 65.7 % for symptomatic patients in comparison to 81.7 % for the incidental group, which implies high statistical signification (log rank = 0.0018)

Conclusions

In our series no significant differences were detected between incidental and symptomatic tumours when comparing age, sex, anatomic side and histological type. Significant differences were indeed detected in relation to size, degree of cellular differentiation, tumour stage and survival
