Prostate Cancer P D:中危前列腺癌患者主动监测后的病理结果分析

2021-10-06 AlexYang MedSci原创

调查了中危前列腺癌患者主动监测后的病理结果。

目前,对局部前列腺癌的男性的治疗模式为风险分层,将患者分成主动监测(AS)和确定性治疗两类。使用前列腺特异性抗原(PSA)水平用来划分AS与确定性治疗,在不同的系列中有很大差异。在某些大型AS系列中,PSA>10 ng/ml用来排除非AS男性。PSA的绝对值也是导致病人和医生对AS焦虑的一个因素。

主动监测(AS)普遍认为是低风险前列腺癌男性患者的首选方案。目前的指南将前列腺特异性抗原(PSA)10-20ng/ml,或低容量活检格里森等级组(GG)2作为特征,在一定程度上定义了有利的中危疾病,并建议对这一风险类别的一些男性可以考虑采用AS。

近期,来自美国的研究人员在《Prostate Cancer P D》上发表文章,调查了中危前列腺癌患者主动监测后的病理结果

研究包括了26548名接受AS管理的男性,年龄<80岁,临床局部前列腺癌(cT1-2cN0M0),PSA≤20 ng/ml,活检GG≤2,阳性核百分比≤33%,并最终转换为前列腺根治术(RP)治疗。根据PSA水平(<10 vs 10-20 ng/mL)和GG(1 vs 2)进行多变量逻辑回归,确定了RP时的不良病理预测因素。

结果发现,在1731名患有GG 1疾病和PSA 10-20 ng/mL的男性中,382人(22.1%)存在不良病理,而在8367名GG 2和PSA<10 ng/mL的男性中,2340人(28%)在RP时有不良病理。在多变量分析中,调整后PSA为10-20 ng/mL患者的不良病理几率(几率[OR]1.87,95%置信区间[CI]1.71-2.05,P<0.001)小于GG 2患者(OR 2.56,95%CI 2.40-2.73,P<0.001)。

PSA水平和活检等级组预测RP时不良病理的多变量逻辑回归分析

综上所述,他们的结果支持将AS标准更多地使用到仔细挑选的PSA 10-20 ng/ml和GG 1疾病的男性
