High-risk human papillomavirus (HR-HPV) infection has been increasingly recognized as a risk factor for sinonasal tract carcinomas. However the prevalence and prognostic significance of HPV-associated sinonasal carcinomas is not well known due to limited studies and inconsistency in HPV testing modalities in literatures. Morphologically, HPV-associated sinonasal carcinomas encompass a diverse group of tumors. HPV-associated sinonasal adenocarcinoma has not been reported. The purpose of this study was to determine the prevalence, morphologic spectrum and prognostic implication of HPV-associated sinonasal carcinomas.
This cohort included 153 sinonasal carcinomas. Tissue microarrays were constructed. P16 immunohistochemistry and HR-HPV E6/7 in-situ Hybridization (ISH) were performed. Carcinomas were deemed HPV-associated based on a positive ISH testing. Clinicopathologic data was collected.
28/153 (18%) sinonasal carcinomas were HPV-associated. HPV-associated carcinomas consisted of 26 (93%) squamous cell carcinomas and variants, 1 (3.5%) HPV-related multiphenotypic sinonasal carcinoma and 1 (3.5%) adenocarcinoma. The HPV-associated adenocarcinoma closely resembled HPV-associated endocervical adenocarcinoma morphologically. HPV-associated carcinomas occurred in 8 (29%) women and 20 (71%) men with a median age of 66 years old. HPV-associated carcinomas were predominantly located at nasal cavity. A trend toward improved overall survival and progression free survival in HPV-associated carcinomas patients was observed, yet without statistical significance.
Our study identifies a novel HPV-associated sinonasal adenocarcinoma subtype, highlights the broad morphologic spectrum of HPV-associated sinonasal carcinomas, and supports routine p16 testing during pathology practice regardless of tumor subtype followed by a confirmatory HR-HPV testing. This practice is critical for studying the clinical behavior of HPV-associated sinonasal carcinomas.
高危型人乳头瘤病毒(HR-HPV)感染已被越来越多地认为是鼻窦道癌的危险因素。然而,由于文献中 HPV 检测方法的研究有限且不一致,HPV 相关鼻窦癌的流行率和预后意义尚不清楚。从形态学上看,HPV 相关的鼻窦癌包括一组多样化的肿瘤。尚未报道 HPV 相关的鼻窦腺癌。本研究的目的是确定 HPV 相关鼻窦癌的流行率、形态谱和预后意义。
本队列包括 153 例鼻窦癌。构建组织微阵列。进行 P16 免疫组化和 HR-HPV E6/7 原位杂交(ISH)。根据 ISH 检测阳性,将癌判定为 HPV 相关。收集临床病理数据。
153 例鼻窦癌中有 28 例(18%)为 HPV 相关。HPV 相关癌由 26 例(93%)鳞状细胞癌及其变体、1 例(3.5%)HPV 相关多表型鼻窦癌和 1 例(3.5%)腺癌组成。HPV 相关腺癌在形态上与 HPV 相关的宫颈内膜腺癌非常相似。HPV 相关癌发生于 8 例(29%)女性和 20 例(71%)男性,中位年龄为 66 岁。HPV 相关癌主要位于鼻腔。HPV 相关癌患者的总生存和无进展生存有改善的趋势,但无统计学意义。
本研究确定了一种新型的 HPV 相关鼻窦腺癌亚型,强调了 HPV 相关鼻窦癌的广泛形态谱,并支持无论肿瘤亚型如何,在病理实践中常规进行 p16 检测,然后进行 HR-HPV 检测。这种做法对于研究 HPV 相关鼻窦癌的临床行为至关重要。
