Munari, Fernanda Franco; Sichero, Laura; Carloni, Adriana Cruvinel; Lacerda, Croider Franco; Nunes, Emily Montosa; De Oliveira, Antônio Talvane TorresMade available in DSpace on 2022-04-29T08:35:38Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Background: Chagasic megaesophagus (CM) as well as the presence of human papillomavirus (HPV) has been reported as etiological factors for esophageal squamous cell carcinoma (ESCC). Objective: We assessed the prevalence of HPV DNA in a series of ESCCs associated or not with CM. Data obtained were furthe...
Human papillomavirus is not associated to non-small cell lung cancer: data from...
Silva, Estela Maria; Mariano, Vânia Sammartino; Pastrez, Paula Roberta Aguiar; Pinto, Miguel Cordoba; Nunes, Emily Montosa; Sichero, LauraBackground: The pathogenesis of lung cancer is triggered by a combination of genetic and environmental factors, being the tobacco smoke the most important risk factor. Nevertheless, the incidence of lung cancer in non-smokers is gradually increasing, which demands the search for different other etiological factors such as occupational exposure, previous lung disease, diet among others. In the early 80's a theor...

Prevalence of high risk HPV DNA in esophagus is high in Brazil but not related ...
Costa, Allini Mafra da; Fregnani, José Humberto Tavares Guerreiro; Pastrez, Paula Roberta Aguiar; Mariano, Vânia SammartinoThe first publication that associated Human Papillomavirus (HPV) infection and esophageal cancer was published in 1982. However, data are still contradictory and require further investigation. The aim of this study was to identify high risk HPV DNA in esophageal tissue of patients with and without esophageal squamous cell carcinoma (ESCC) and correlate HPV presence with classical risk factors. METHODS: Invited ...
The relation of HPV infection and expression of p53 and p16 proteins in esophag...
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...
