Prostate Cancer P D:前列腺成像报告和数据系统评分在格林森3+3积极监控患者中作用探究

2018-11-27 AlexYang MedSci原创

当代的积极监控(AS)标准可能导致一定的错误鉴定比例,并且可能推迟前列腺癌患者的根治性治疗。核磁共振成像(MRI)不包括在任何AS标准中,但能够为前列腺癌诊断提供有用的信息。最近,有研究人员评估了一个标准的MRI报告系统-前列腺成像报告和数据系统(PI-RADS)评分在AS候选者中的诊断表现。研究人员从168个研究中发现了5个研究提供了PI-RADS评分的诊断数据和病理结果;并包括了834名患者。

当代的积极监控(AS)标准可能导致一定的错误鉴定比例,并且可能推迟前列腺癌患者的根治性治疗。核磁共振成像(MRI)不包括在任何AS标准中,但能够为前列腺癌诊断提供有用的信息。最近,有研究人员评估了一个标准的MRI报告系统-前列腺成像报告和数据系统(PI-RADS)评分在AS候选者中的诊断表现。

研究人员从168个研究中发现了5个研究提供了PI-RADS评分的诊断数据和病理结果;并包括了834名患者。这些研究中所有AS候选者均通过前列腺癌研究国际标准-积极监控(PRIAS)标准来确定。PI-RADS 4或者5的关于AS候选者根治性前列腺切除(RP)副作用病理特性混合评估包括:敏感度,0.77 (95% 置信区间(CI), 0.71-0.82);特异性,0.63 (95% CI, 0.55-0.71);阳性预测值,0.72 (95% CI, 0.64-0.79);阴性预测值,0.68 (95% CI, 0.63-0.73)和诊断风险比,6 (95% CI, 4-8)。SROC曲线位于预想的曲线左上角,曲线下面积为0.77(95% CI, 0.73-0.80)。另外,异质性的P值小于0.01。病理结果和直肠内线圈能够促进遗传异质性的敏感度。PI-RADS v2比v1更加优越的证据并不充分。

最后,研究人员指出,具有PI-RADS 4或者5的AS候选者可能不适合AS,尽管他们目前符合AS标准。那些PI-RADS 3或者更少的表明AS情况下相对是安全的。

前列腺是男性生殖器附属腺中最大的实质性器官。由前列腺组织和肌组织构成。前列腺癌是指发生在前列腺的上皮性恶性肿瘤。2004年WHO《泌尿系统及男性生殖器官肿瘤病理学和遗传学》中前列腺癌病理类型上包括腺癌(腺泡腺癌)、导管腺癌、尿路上皮癌、鳞状细胞癌、腺鳞癌。其中前列腺腺癌占95%以上,因此,通常我们所说的前列腺癌就是指前列腺腺癌。梅斯医学小编整理了近期前列腺癌的研究进展,与大家一起分享学习!【1
