Skeletal-Related Events in Patients with Metastatic Renal Cell Carcinoma: A Systematic Review

About one-third of advanced renal cell carcinoma (RCC) patients have bone metastases, which subsequently leads to the development of skeletal-related events (SREs), broadly defined to include surgery and radiation to bone, bone pain, pathological fracture, spinal cord compression, or hypercalcemia. The cumulative impact of SREs in RCC has not been well studied. SREs increase morbidity and mortality of RCC patients, although many interventions do significantly reduce their rates of development and improve prognosis. We performed a systematic review from the existing literature in PubMed from January 2002 through September 2019 and summarized the body of evidence regarding the development, prevention, prognosis and treatment of SREs in advanced RCC patients.
