ABSTRACT

El síndrome de lisis tumoral (SLT) es un trastorno metabólico que ocurre como consecuencia de una destrucción celular masiva. Se caracteriza por la presencia de hiperuricemia, hiperfosfatemia, hipocalcemia e hiperkalemia, y predispone al desarrollo de insuficiencia renal aguda. En la mayoría de los casos el SLT ocurre luego de instaurarse un tratamiento antitumoral y es más frecuente en tumores de alto grado de malignidad y alta sensibilidad a la quimioterapia. Presentamos el caso de un paciente con diagnóstico de cáncer de riñón recidivado que presenta un SLT e insuficiencia renal aguda luego de iniciar tratamiento con sunitinib.


The tumor mor lysis syndrome (TLS) is a metabolic disorder resulting from a massive tumor breakdown. It is characterized by hyperuricemia, hyperphosphatemia, hypocalcemia and hyperkalemia and predisposes to acute renal failure. TLS usually occurs after the initiation of cytotoxic therapy and is more frequent in the case of neoplasias with a high proliferative rate or that are highly chemo-sensitive. We report the case of a man with a recurrent kidney cancer who presented with a TLS and acute renal failure after initiation of sunitinib.
