THP在早期非肌层侵润性膀胱癌定位诊断与治疗中的临床应用

目的:探讨THP在早期非肌层侵润性膀胱癌定位诊断与治疗中的临床应用价值。方法:已诊断非肌层侵润性膀胱癌患者45例,术中均实行THP膀胱灌注,灌注后15min置入膀胱镜,观察膀胱内粘膜,将THP橙色染色区域作为实验组进行活检,其他未染色区域作为对照组随机活检,活检组织行病理检查。TUR-BT术后将45例患者随机分为3组,在不同的时间点开始灌注(术后即刻、术后6小时、术后7天),比较复发率和平均复发时间。结果:两组间比较具有统计学意义(P<0.05)恶性粘膜吸收THP敏感度和特异度分别为100%、63.5%;TUR-BT术后即刻灌注及6小时后灌注的总复发率明显低于术后7天灌注,差异有统计学意义(P<0.05)。结论:THP对非肌层侵润性膀胱癌早期定位诊断准确、安全性好,同时术后早期灌注THP可以降低肿瘤的复发率,值得临床推广。

Clinical Application of Localization Diagnosis and Treatment in the Early Non-Muscle Invasive Bladder Cancer with THP*

Objective: To discuss the value of clinical application in the early non-muscle invasive bladder cancer with THP.Methods: 45 patients which had been diagnosised non-muscle invasive bladder cancer were selected as research subjects.The patients re-ceived intravesical treatment with THP in operation and observated the bladder mucosa 15 minutes after intravesical treatment with cys-toscopy.THP orange stained area was biopsied as the experimental group for pathological examination and other unstained area as th...
