Abstract

Background: The detection rate of oncogenic human papillomaviruses (HPVs) in sinonasal squamous cell carcinomas (SNSCCs) varies among studies. The mutational landscape of SNSCCs remains poorly investigated.

Methods: We investigated the prevalence and prognostic significance of HPV infections based on p16 protein expression, HPV-DNA detection, and E6/E7 mRNA expression using immunohistochemistry, polymerase chain reaction, and in situ hybridization, respectively. In addition, we evaluated the genetic mutations in 59 patients using next-generation sequencing.

Results: One-third of the SNSCCs were truly oncogenic HPV-driven tumors associated with a nonkeratinizing morphology (p = 0.01) and did not correlate with the prognosis. The following gene mutations were detected: TP53, PIK3CA, CDKN2A, EGFR, and FGFR3. These mutations occurred alone, in association with, or with oncogenic HPV.

Conclusion: One-third of SNSCCs were high-risk HPV driven lesions. However, gene mutations and HR-HPV infections are not mutually exclusive. Further studies are required to analyze the prognostic value of these associations.

背景：鼻窦鳞状细胞癌（SNSCC）中致癌人类乳头瘤病毒（HPV）的检出率因研究而异。对鼻窦鳞状细胞癌突变情况的研究仍然很少：方法：我们使用免疫组化、聚合酶链反应和原位杂交技术，根据 p16 蛋白表达、HPV-DNA 检测和 E6/E7 mRNA 表达，调查了 HPV 感染的流行率和预后意义。此外，我们还利用新一代测序技术评估了59名患者的基因突变情况：结果：1/3的SNSCC是真正的致癌型HPV驱动肿瘤，与非角化形态相关（p = 0.01），与预后无关。检测到以下基因突变：TP53、PIK3CA、CDKN2A、表皮生长因子受体和表皮生长因子受体 3。这些基因突变有的单独发生，有的与致癌 HPV 共同发生，有的与致癌 HPV 共同发生：结论：三分之一的SNSCC是高危HPV驱动的病变。然而，基因突变和HR-HPV感染并不相互排斥。需要进一步研究分析这些关联的预后价值。
