中文摘要
背景:肾癌仍是侵袭性最强、致死率最高的泌尿系统恶性肿瘤之一。为解决这一问题,我们开发并临床验证了Geneverify基于血液的无细胞mRNA检测,这是一种前沿的液体活检平台,能够实现实时、非侵入性的基因组图谱分析。通过对血浆中循环肿瘤来源转录本进行定量,这一新一代检测提供快速而精确的分子洞见,为精准筛查、早期诊断和治疗监测铺平道路。
方法:在这项前瞻性临床研究中,我们评估了来自51名受试者(41例疑似癌症病例和10例健康对照)血浆样本中30个肾癌相关基因的实时表达水平。主要目标是评估由Geneverify公司开发的基于血液的多基因表达panel的诊断和预后性能。为每个基因计算Log₂倍数变化值,并加以整合以生成每位受试者的复合Geneverify风险评分。将Geneverify评分与活检确诊的诊断进行比较,以确定检测的敏感性和特异性。其他统计学分析评估了Geneverify评分与病理分级以及临床分期之间的相关性。
结果:所有癌症样本的Geneverify评分均大于10。采用优化的阈值10,该检测在检测癌症病例方面达到了100%的敏感性。由于研究队列不包括良性或非癌症受试者,因此无法确定特异性;相应地,相对于非癌症对照的AUC也无法估算。来自健康志愿者的基线Geneverify评分作为比较的参照。队列中大多数患者为T1a(早期)肾癌。升高的Geneverify评分与肿瘤分期、分级和治疗状态显示出明确的相关性。在大多数接受全身治疗的晚期转移性病例中,Geneverify评分显著下降,提示良好的治疗应答。
结论:本研究提供了首个针对肾癌检测的基于血液的无细胞mRNA基因组检测的实时临床验证。Geneverify检测展现出高诊断准确性、与活检结果的强一致性以及稳健的预后价值,确立了其作为早期检测强有力的非侵入性替代方案的地位。将其纳入临床工作流程可能减少手术活检、改善患者分层并加速个体化肿瘤诊疗。

Background: Kidney cancer remains one of the most aggressive and fatal urological malignancies. To address this issue, we developed and clinically validated the Geneverify blood-based, cell-free mRNA test, a cutting-edge liquid biopsy platform that enables real-time, non-invasive genomic profiling. By quantifying circulating tumor-derived transcripts in plasma, this next-generation assay delivers rapid and precise molecular insights, paving the way for precision screening, early diagnosis, and treatment monitoring.
Methods: In this prospective clinical study, we evaluated real-time expression levels of 30 kidney cancer associated genes in plasma samples from 51 subjects (41 suspected cancer cases and 10 healthy controls). The primary objective was to assess the diagnostic and prognostic performance of a blood-based multi-gene expression panel developed by Geneverify Inc. Log₂ fold-change values were calculated for each gene and integrated to generate a composite Geneverify risk score for each subject. Geneverify scores were compared with biopsy-confirmed diagnoses to determine assay sensitivity and specificity. Additional statistical analyses assessed correlations between Geneverify scores and pathological grade as well as clinical stage.
Results: All cancer samples demonstrated Geneverify scores greater than 10. Using an optimized threshold of 10, the assay achieved 100% sensitivity in detecting cancer cases. Specificity could not be determined because the study cohort did not include benign or non-cancer subjects; therefore, AUC relative to non-cancer controls was also not estimable. Baseline Geneverify scores from healthy volunteers served as the reference for comparison. Most patients in the cohort had T1a (early-stage) kidney cancer. Elevated Geneverify scores showed clear correlations with tumor stage, grade, and treatment status. In the majority of late-stage metastatic cases receiving systemic therapy, Geneverify scores decreased significantly, suggesting a favorable treatment response.
Conclusions: This study provides the first real-time clinical validation of a blood-based, cell-free mRNA genomic assay for kidney cancer detection. The Geneverify test demonstrated high diagnostic accuracy, strong concordance with biopsy results, and robust prognostic value, establishing it as a powerful non-invasive alternative for early detection. Its adoption in clinical workflows may reduce surgical biopsies, improve patient stratification, and accelerate personalized oncology care.
