The article by Skinner et al therefore addresses an important topic — what is the relationship between multiple HPV-related malignancies in a single individual? This question has previously been addressed using epidemiological approaches, but not in a comprehensive chart review. Skinner and Beadle present a retrospective review of patients treated at their institution over a 60-year period starting in 1949 with the intent of understanding which patients are at risk for HPV-related malignancies, specifically, are patients with one HPV-related malignancy more likely to have additional HPV-related malignancies. It is logical to assume that HPV exposure may predispose to a phenotype of multiple cancers in susceptible organs. Using administrative data, others have shown that patients with a history of cervical cancer are at risk for a head and neck cancer primary (1.7 incidence ratio). Conversely, patients with oropharyngeal cancer are at increased risk for cervical cancer. Skinner et al have investigated additional tumor sites and determined latency and associated clinical characteristics. Among other findings, the authors identify significant differences in latency periods between first and second HPV-related cancers depending on the initial cancer site. Related to methodological problems, the authors acknowledge that the results “should be interpreted as hypothesis-generating” and recognize some other deficiencies in the discussion; however, these shortcomings and potential interpretations warrant additional comment. Although this article addresses an important topic, there are several methodological issues that should be recognized in the data collection. The head and neck cancer population included all sites rather than the oropharynx and, as a result, probably significantly overestimates the number of HPV-related cancers. Elimination of patients with disease outside the oropharynx or preferably some method of HPV testing tissue (p16 immunohistochemistry or HPV in situ hybridization) of archival tumor specimens, would significantly improve identification of HPVrelated malignancies. It is fair to say that many patients with oropharyngeal disease get primary medical therapy and, as a result, there is often limited tissue available for laboratory analysis. However, limiting the study to patients with oropharyngeal disease and eliminating patients with laryngeal or oral cavity disease, especially over the time frame of the study, would be very appropriate although it would also shrink the overall study numbers. Because HPV-related head and neck malignancies have trended upward over time, it is likely that, over the 60-year study period, the incidence of HPV-related oropharyngeal cancer has significantly increased just as t","PeriodicalId":501638,"journal":{"name":"Head & Neck","volume":" ","pages":"826-7"},"PeriodicalIF":2.9,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/hed.23378","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"31448344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
