目的:提高对原发性膀胱印戒细胞癌(PBSRCC)的诊治水平。方法:结合文献回顾性分析3例PBSRCC患者的临床、病理资料。结果:3例均经手术治疗,术后病理均诊断为PBSRCC,分别于术后6～13个月死亡。结论:PBSRCC是一种罕见的恶性肿瘤,预后差。影像学检查及膀胱镜检的综合应用是诊断PBSRCC的主要方法。根治性全膀胱切除是惟一有效的治疗方法。
Objective: To improve the diagnosis and treatment of primary bladder signet ring cell carcinoma (PBSRCC). Methods: Clinical and pathological data of 3 patients with PBSRCC were retrospectively analyzed. Results: All the 3 cases were surgically treated. Postoperative pathology was diagnosed as PBSRCC, which died 6 to 13 months after operation. Conclusion: PBSRCC is a rare malignant tumor with poor prognosis. Imaging and cystoscopy combined application is the main method of diagnosis of PBSRCC. Radical total cystectomy is the only effective treatment.
