Objective: To investigate the clinical characteristics,prognosis, survival and diagnosis of primary renalsarcoma.
Methods: In the study,17 cases of renal sarcoma were reviewed and analyzed, the incidence, clinical manifestations, treatments and prognosis of renal sarcoma discussed and analyzed, and the correlated literature also reviewed.
Results: Radical nephrectomy was the main treatment for 16 cases, one case was punctured and pathologized. The distributions of pathology were leiomyosarcoma, malignant fibrous histiocytoma, rhabdomyosarcoma, synoviosarcoma, liposarcoma, and clear-cell sarcoma. Thirteen of the subjects were followed-up, and the time of survival varied from 7 to 132 months.
Conclusion: Renal sarcomas are rare and highly malignant and the prognosis is poor. Early diagnosis and radical nephrectomy can prolong the patient's life.
