DESCRIPTION (provided by applicant): High risk human papilloma virus related head and neck squamous cell carcinoma (HPVHNSCC) incidence is rapidly increasing, and will soon surpass the incidence of cervical carcinoma in the US. There are no effective ways to detect preclinical or early HPVHNSCC, screen populations at increased risk for HPVHNSCC development, or even assay for microscopic persistence of HPVHNSCC after therapy. However, epigenetic alterations have been detected in body fluids from premalignant and early stage cancers and multiplex tests have shown promise for identification of patients with oral premalignancy. Our primary hypothesis is that multiplex testing of plasma and salivary rinses based on HPVHNSCC specific epigenetic alterations combined with high risk HPV DNA presence has potential as useful test for presence of HPVHNSCC. This project will serve as a discovery and diagnostic validation biomarker development trial for HPVHNSCC detection with potential application for assessment of disease response and development of a population based screening test.

描述（申请人提供）：在美国，高危人乳头瘤病毒相关头颈鳞状细胞癌（HPVHNSCC）发病率正在迅速增加，很快将超过宫颈癌的发病率。没有有效的方法来检测临床前或早期 HPVHNSCC、筛查 HPVHNSCC 发生风险增加的人群，甚至检测治疗后 HPVHNSCC 的微观持续性。然而，在癌前和早期癌症的体液中检测到表观遗传改变，并且多重测试已显示出识别口腔癌前患者的希望。我们的主要假设是，基于 HPVHNSCC 特异性表观遗传改变与高危 HPV DNA 的存在相结合，对血浆和唾液冲洗液进行多重检测，有可能成为检测 HPVHNSCC 是否存在的有用方法。该项目将作为 HPVHNSCC 检测的发现和诊断验证生物标志物开发试验，具有评估疾病反应和开发基于人群的筛查测试的潜在应用。
