A biochemical recurrence (BCR) risk model was created based on pretest prostate specific antigen (PSA) and groupings by restaging prostate specific membrane antigen (PSMA) PET/CT.
A cohort of 1216 BCR patients were analyzed for overall survival (OS) according to the PSA threshold and restaging PSMA PET/CT. A Cox regression analysis of OS was carried out to detect significant clinical characteristics.
In the cohort, 271 patients had a pretest PSA of <0.5 ng/mL and 945 patients had higher PSA values. The restaging PSMA PET/CT was positive for 834 patients and negative for 369. Of 1203 patients, 133 (11%) died, including 19 of the 369 (5%) patients without positive sites on the restaging PSMA PET/CT, 82 of the 711 (12%) with 1-5 positive sites, and 32 of the 123 (26%) with >5 positive sites. In the Cox regression analysis, four variables significantly predicted OS: treatment center, International Society of Urologic Pathology (ISUP) grade, pretest PSA threshold, and the grouping of positive sites on the restaging PSMA PET/CT.
The pretest PSA and PSMA PET/CT were important for the OS of the BCR patients. The findings argue for the new BCR risk model and serve as framework for ongoing trials.
基于检测前前列腺特异性抗原(PSA)以及通过重新分期的前列腺特异性膜抗原(PSMA)PET/CT进行分组,创建了生化复发(BCR)风险模型。
根据PSA阈值和重新分期的PSMA PET/CT,对1216例BCR患者的总生存期(OS)进行分析。对OS进行Cox回归分析以检测显著的临床特征。
在该队列中,271例患者检测前PSA<0.5 ng/mL,945例患者PSA值更高。重新分期的PSMA PET/CT对834例患者呈阳性,对369例患者呈阴性。在1203例患者中,133例(11%)死亡,包括369例重新分期PSMA PET/CT无阳性部位患者中的19例(5%)、711例有1 - 5个阳性部位患者中的82例(12%)以及123例有>5个阳性部位患者中的32例(26%)。在Cox回归分析中,四个变量显著预测OS:治疗中心、国际泌尿病理学会(ISUP)分级、检测前PSA阈值以及重新分期PSMA PET/CT上阳性部位的分组。
检测前PSA和PSMA PET/CT对BCR患者的OS很重要。这些发现支持新的BCR风险模型,并为正在进行的试验提供框架。
