目的通过临床资料与经尿道膀胱肿瘤电切术(TURBT)的结果对比并联合膀胱癌的病理学分级,对膀胱癌的临床分期进行准确率评估。方法将32例膀胱癌根治术后患者的肿瘤浸润深度、盆腔淋巴结转移情况、TURBT术后结果、CT扫描等结果与最终病理报告进行对比。结果其中7例女性及25例男性患者,双合诊诊断膀胱外受累患者,敏感性为46%,特异性为82%。通过肿瘤大小判断膀胱外受累患者敏感性为93%,特异性为41%。CT扫描诊断盆腔淋巴结转移和周围脂肪侵袭的敏感性为46%,特异性为70%。结论临床分期在浸润性膀胱癌并发膀胱周围脂肪及盆腔淋巴结转移时没有显示较高的敏感性。肾积水为肿瘤肌层转移较敏感的一个阳性预测值。
Objective To evaluate the clinical staging of bladder cancer by comparing the clinical data with the results of TURBT and the pathological grading of bladder cancer. Methods The tumor invasion depth, pelvic lymph node metastasis, TURBT postoperative results and CT scan of 32 patients with radical mastectomy were compared with the final pathological reports. Results Seven of the women and 25 male patients were diagnosed as having extracranial involvement by dual diagnosis. The sensitivity and specificity were 46% and 82% respectively. Sensitivity and specificity were 93% and 41%, respectively. The sensitivity and specificity of CT scan in diagnosing pelvic lymph node metastasis and peripheral fat invasion were 46% and 70% respectively. Conclusion The clinical stage does not show high sensitivity in infiltrative bladder cancer with vesical fat and pelvic lymph node metastasis. Hydronephrosis is a more sensitive predictor of myometrial metastases.
