Risk factors for the development of an upper urinary tract transitional cell carcinoma following radical cystectomy are identified.
The records of 430 patients who underwent cystectomy for transitional cell carcinoma of the bladder between 1981 and 1988 were retrospectively reviewed.
Upper tract tumors developed in 11 patients (2.6%) at a median of 40 months after radical cystectomy. Of the potential risk factors evaluated only the presence of transitional cell carcinoma within the distal ureter showed a statistically significant correlation with upper tract recurrence (p = 0.001). Six of the 11 recurrent neoplasms were asymptomatic. Among the patients with upper urinary tract recurrence 5 died of disease, 4 had no evidence of disease and 2 were alive with cancer.
Patients with distal ureteral involvement at cystectomy are at a high risk for upper tract recurrence. These patients should be monitored with routine upper tract cytology and imaging studies.
确定根治性膀胱切除术后上尿路移行细胞癌发生的危险因素。
回顾性分析1981年至1988年间因膀胱移行细胞癌接受膀胱切除术的430例患者的病历。
11例患者(2.6%)在根治性膀胱切除术后中位40个月时发生上尿路肿瘤。在评估的潜在危险因素中,仅远端输尿管内存在移行细胞癌与上尿路复发具有统计学显著相关性(p = 0.001)。11例复发性肿瘤中有6例无症状。在上尿路复发的患者中,5例死于疾病,4例无疾病证据,2例带癌生存。
膀胱切除术中远端输尿管受累的患者上尿路复发风险高。这些患者应通过常规上尿路细胞学检查和影像学检查进行监测。
