Abstract

Significance: HPV+OPSCC incidence is increasing, with heterogeneous treatment outcomes despite favorable prognosis. Current de-escalation strategies show inferior results, highlighting the need for precise risk stratification. Using data-independent acquisition mass spectrometry proteomics, we identified a 26-peptide signature that stratifies patients into risk categories, potentially enabling personalized treatment decisions and optimal patient selection for de-escalation trials.

人乳头状瘤病毒相关口咽鳞状细胞癌的蛋白质组特征可预测高复发风险患者。
尽管HPV阳性OPSCC的预后优于HPV阴性病例,但仍有约30%的病例在接受治愈性放疗(+/-化疗)后复发。我们的目标是建立一个与HPV+OPSCC复发风险相关的蛋白质组特征。我们分析了 124 例 T1-4N0-3M0 HPV+OPSCC 患者的肿瘤标本:50 例在治疗后 5 年内有残留或复发的患者,以及 74 例年龄和表现状态相匹配且无复发的患者。采用定量数据无关采集质谱法(DIA-MS)对存档的FFPE原发肿瘤核心活检标本和匹配的正常邻近组织(NAT)进行了蛋白质组分析。无复发生存期(RFS)是主要终点,包括局部和远处无复发生存期。单变量 Cox 回归分析确定了与 RFS 相关的肽段,并据此建立了风险评分,生成了基于肽段的特征。在整个组群中共鉴定出7597个蛋白质组,其中1565个蛋白质组在肿瘤和NAT中含量不同,1218个蛋白质组在肿瘤中含量显著增加。5年RFS(q值
