Pastrez, Paula Roberta Aguiar; Mariano, Vânia Sammartino; Costa, Allini Mafra da; Silva, Estela Maria; Scapulatempo-Neto, CristovamGOAL: To investigate the HPV prevalence and characterize the expression of potential molecular surrogate markers of HPV infection in esophageal squamous cell carcinoma. MATERIALS AND METHODS: The prevalence of HPV in individuals with and without esophageal cancer (EC) was determined by using multiplex PCR; p16 and p53 protein levels were assessed by immunohistochemistry (IHC). RESULTS: High-risk HPV (hr-HPV) wa...
