目的:提高乳头状肾癌的诊治水平。方法:回顾性分析32例乳头状肾癌患者的临床资料。28例行开放性根治性肾切除术,3例行后腹腔镜下根治性肾切除术,1例行后腹腔镜下肾部分切除。结果:术后病理均为乳头状肾癌。采用2002年AJCC肾癌TNM病理分期:pT1aN0M04例,pT1bN0M014例,pT2aN0M010例,pT2bN0M01例,pT2bN1M01例,pT3aN0M02例,病理分级:G121例,G210例,G31例。28例获16～30个月随访,平均20个月,2例死于心脏病,3例死于脑血管意外,1例局部复发,22例无瘤生存。结论:乳头状肾癌是一种具有特殊形态和表现的少见肾癌类型,部分肾切除及根治性肾切除术是治疗乳头状肾癌的首选方法,与其他类型肾细胞癌相比,乳头状肾癌预后较好。
Objective: To improve the diagnosis and treatment of papillary renal cell carcinoma. Methods: The clinical data of 32 patients with papillary renal cell carcinoma were retrospectively analyzed. 28 cases underwent open radical nephrectomy, 3 cases underwent laparoscopic radical nephrectomy, and 1 case underwent laparoscopic partial nephrectomy. Results: Postoperative pathology were papillary renal cell carcinoma. Using 2002 AJCC renal cell carcinoma TNM pathological staging: pT1aN0M04 cases, pT1bN0M014 cases, pT2aN0M010 cases, pT2bN0M01 cases, pT2bN1M01 cases, pT3aN0M02 cases, pathological grade: G121 cases, G210 cases, G31 cases. Twenty-eight patients were followed up for 16 to 30 months with an average of 20 months. Two died of heart disease, three died of cerebrovascular accident, one had local recurrence and 22 had no tumor. Conclusion: Papillary renal carcinoma is a rare type of renal cell carcinoma with special morphology and appearance. Partial nephrectomy and radical nephrectomy are the preferred methods of treatment of papillary renal cell carcinoma. Compared with other types of renal cell carcinoma, papillary Renal cancer prognosis is better.
