Abstract

Serum samples from 62 patients with seminoma were assayed for placental alkaline phosphatase-like activity using the monoclonal antibody H17 E2, in order to evaluate its utility as a serum tumour marker. Fifteen of 16 patients (94%) with active seminoma had elevated serum PLAP levels. Sixteen of 46 (35%) of patients considered to be in remission had elevated PLAP levels (false positive rate 35%). Fifteen false positive results were considered attributable to concomitant smoking, and if these patients are excluded, only one false positive case was detected. In 7 out of 7 patients sequential PLAP assays reflected clinical response to treatment.

摘要

使用单克隆抗体H17 E2对62例精原细胞瘤患者的血清样本进行胎盘碱性磷酸酶样活性检测,以评估其作为血清肿瘤标志物的效用。16例活动性精原细胞瘤患者中有15例(94%)血清PLAP水平升高。46例处于缓解期的患者中有16例(35%)PLAP水平升高(假阳性率35%)。15例假阳性结果被认为归因于同时吸烟,如果排除这些患者,仅检测到1例假阳性病例。7例患者中有7例连续的PLAP检测反映了对治疗的临床反应。
