Both mucosal and cutaneous papillomaviruses are in the oral cavity but only alpha genus seems to be associated with cancer

Human Papillomavirus Infection and Human Cancer

“…It is interesting to find that only 18% out of 205 staff nurses in the Rural Institute of Medical Sciences and Research, Saifai, Etawah in India knew about HPV vaccination [Singh et al 2012]. Totally, 360 consecutive outpatients of a dermatological clinic were interviewed about HPV infections, genital and anal warts as well as cancer using a self-administred questionnaire -77.2% answered the quostions; 39.4% of the outpatients had heard about HPV-induced infections and 23.9% about HPV vaccination [Kuznetsov et al 2012 Lee et al [2012] and Paolini et al [2012]. Oropharyngeal cancer is an important neoplasm to study due to oral sex which exposes individuals to HPVs [Minn 2012]; also zur Hausen [2011] underlines the importance of oral sex in the devel-opment of oropharyngeal cancer.…”

“…HPVs in the oral cavity are associated with oropharyngeal cancers but only HPV 16 is found to be clearly connected to these tumours [Paolini et al 2012].…”

Detection of Human Papillomavirus among Patients with Clinically Diagnosed Cutaneous Warts by PCR Method

“…HPVs are divided into mucosal and cutaneous types [2]. Mucosal types target the mucosal membranes which in turn causes cervical neoplasia in women and anogenital warts in adults and children.…”

Prevalência e diversidade de beta-papilomavírus em amostras anogenitais e orais de homens do estudo HIM

“…Homens residentes no EUA (OR = 0,55, 95% intervalo de confiança [IC] de 0,38-0,80) e Brasil (OR = 0,49, 95% CI 0, 73) foram significativamente menos propensos a serem detectados com algum β-HPV no canal anal, comparado aos residentes no México. A idade foi marginalmente associada à maior prevalência de HPV na região do canal anal sendo que de homens mais velhos (31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)OR = 1,30,95% CI 0,82;OR = 1,59,95% CI 0,58) foram mais propensos a serem positivos para DNA de β-HPV, comparado a homens mais jovens (18-30 anos). A prevalência de algum β-HPV na cavidade oral também foi significativamente associada ao país de residência e idade.…”

“…Samples were tested for PCR amplification with PGMY09/11 primers, and HPV genotyping was conducted with the Roche Linear Array (Roche Molecular Diagnostics, Alameda, CA, USA), which is able to discriminate 37 α-HPV types (oncogenic types 16,18,31,33,35,39,45,51,52,56,58,59, and 66; non-oncogenic types 6,11,26,40,42,53,54,55,61,62,64,[67][68][69][70][71][72][73][81][82][83][84]IS39,and CP6108) [14]. Samples that tested PCR-positive and Linear Array-negative with all specific HPV probes were considered to be unclassified and included in the present study.…”
