Kim SM, et al. - Researchers planned this study to ascertain the prevalence and prognosis of human papilloma virus (HPV) associated with oral squamous cell carcinoma (OSCC) according to HPV and tumor types. The obtained data indicated that the DNA microarray method could accurately detect known HPV subtypes simultaneously, however, it had limitations in detecting new subtypes. Moreover, vaccines could be used to prevent HPV-associated OSCC in patients. Thus, further studies on the prognosis and efficacy of vaccines ought to be undertaken.
