Recidiva local y afectación metastásica única de tumor renal. Factores pronósticos y supervivencia

Abstract

ObjectiveTo evaluate the clinical and pathological characteristics and survival in patients surgically treated for renal tumours that had local recurrence or metastasis to a single site. Material and MethodsA retrospective study of 321 nephrectomies, evaluating the clinical and pathological variables in patients having local recurrence or metastasis to a single site, and who were treated surgically. Study and comparison of survival in the different groups. ResultsThe only factor found to have an independent influence on local recurrence is pathological stage. Local recurrence and the presence of metastasis to a single site have similar survival rates, both being statistically worse than in patients without metastasis at diagnosis, but better than in those having metastasis at diagnosis. ConclusionsThe presence of local recurrence has the same prognosis as a single excisable metastatic site, the prognosis being better than those initially with metastasis subjected to nephrectomy before receiving systemic treatment.
