目的:探讨肾恶性间叶瘤的诊断、治疗及预后。方法:回顾性分析3例肾恶性间叶瘤患者的临床资料:男2例,女1例,年龄48～68岁,平均57岁。CT平扫均为肾脏巨大不均质肿物,其中伴有大块状钙化2例,增强扫描不均质肿物有轻至中度强化。3例患者均行根治性肾切除术,术后辅以化疗或放疗。结果:3例患者术后存活6～18个月,平均11个月。结论:肾恶性间叶瘤临床罕见,术前诊断困难,确诊需依靠病理检查。综合分析临床资料及提高对此病的临床认识是避免误诊的关键。根治性切除术是其主要治疗手段,但预后不佳。
Objective: To investigate the diagnosis, treatment and prognosis of malignant mesenchymal neoplasms. Methods: The clinical data of 3 patients with malignant mesenchyme were retrospectively analyzed. There were 2 males and 1 females, aged from 48 to 68 years, with an average of 57 years. CT scan are huge heterogeneous masses of the kidney, which accompanied by massive calcification in 2 cases, enhanced scan heterogeneous mass with mild to moderate enhancement. Three patients underwent radical nephrectomy with postoperative chemotherapy or radiotherapy. Results: Three patients survived 6 to 18 months with an average of 11 months. CONCLUSIONS: Rare malignant mesothelioma is clinically diagnosed preoperatively, and the diagnosis depends on the pathological examination. Comprehensive analysis of clinical data and improve the clinical understanding of the disease is the key to avoiding misdiagnosis. Radical resection is the main treatment, but the prognosis is poor.
