最近,有研究人员在高风险非肌层浸润膀胱癌(NMIBC)患者中评估了低强度和高强度膀胱镜检查与治疗结果的相关性情况。

最近,有研究人员在高风险非肌层浸润膀胱癌(NMIBC)患者中评估了低强度和高强度膀胱镜检查与治疗结果的相关性情况。

研究是一个回顾性的群体研究,包括了2005年和2011年之间诊断为高风险NMIBC的患者,随访至2014年,并将患者根据诊断后2年内膀胱镜检查次数进行分类:低强度(1-5)和高强度(≥6)。 研究发现,在1542名患者中,520(33.7%)名患者经历了低强度膀胱镜检查。低强度膀胱镜检查将患者经历更少的经尿道切除术(37 vs. 99 per 100 person-years; p<0.001)。膀胱癌死亡的风险在低强度(5年累积发生率(Cln)8.4% [95% CI 6.5-10.9)和高强度(5年CIn 9.1% [95% CI 7.4-11.2), p=0.61)患者之间没有显著差异。另外,在诊断为Ta疾病(5年CIn 5.7% vs. 8.2%, p=0.24)或者T1疾病(5年CIn 10.2% vs. 9.1%, p=0.58)的患者中,低强度和高强度检测与膀胱癌死亡风险的增加没有相关性。在Ta疾病患者中,低强度的检测与进展为浸润性疾病(T1或者T2)或者膀胱癌死亡风险的减少相关(5年CIn 19.3% vs. 31.3%,p=0.002)。

最后,研究人员指出,经历低强度和高强度膀胱镜监测的高风险NMIBC患者接受了较少的经尿道切除术,且膀胱癌进展或死亡风险并未增加。这些研究结果为确定低强度监测与高强度监测对高风险NMIBC患者的癌症控制是否相当的临床试验提供了一个强有力的依据。
