TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Recent studies have demonstrated an increase in the incidence of HPV-associated oral squamous cell carcinoma. The aim of this study was to investigate the presentation of HPV in verrucous and papillary lesions of the oral mucosa and the relationship with the prognosis of the patients.', 'Fifty-three biopsy specimens from 31 patients were investigated by polymerase chain reaction using a consensus primer directed to the HPV L1 gene; this was followed by a confirmatory in situ hybridization to identify the HPV types.', 'Fifteen tumor biopsies (28.3%) were positive for the HPV L1 gene, but only 8 specimens (15.1%) were found to be positive using in situ hybridization. The positive rates of HPV L1 gene were 58.8% and 13.9% in malignant and benign verrucous lesions, respectively. HPV infection is independently associated with malignant transformation and disease-specific survival.'] Is human papillomavirus infection in oral papillary and verrucous lesions a prognostic indicator of malignant transformation?
OUTPUT:

agent
yes
