  • Prospective Study of Human Papillomavirus Seropositivity and Risk of Nonmelanoma Skin Cancer

    • Cutaneous human papillomaviruses (HPVs) have been associated with squamous cell carcinoma (SCC) in case-control studies, but there are limited data from prospective studies assessing whether virus exposure predicts risk of future cancer development. Two major biobanks, the Southern Sweden Microbiology Biobank (1971-2003) and the Janus Biobank (1973-2003) in Norway, containing samples from 850,000 donors, were searched for incident skin cancer for up to 30 years using registry linkages. Altogether, 2,623 donors with samples taken before diagnosis of SCC or basal cell carcinoma (BCC) of the skin were identified. Prediagnostic samples and samples from 2,623 matched controls were tested for antibodies against 33 types of HPV. Baseline seropositivity to HPV types in genus beta species 2 was associated with SCC risk (odds ratio = 1.3, 95% confidence interval: 1.1, 1.7); this was also the case for samples taken more than 18 years before diagnosis (odds ratio = 1.8, 95% confidence interval: 1.1, 2.8). Type-specific persistent seropositivity entailed elevated point estimates for SCC risk for 29 HPV types and decreased point estimates for only 3 types. After multiple hypothesis adjustment, HPV 76 was significantly associated with SCC risk and HPV 9 with BCC risk. In summary, seropositivity for certain HPV types was associated with an increased risk for future development of SCC and BCC.

  • Alcohol, smoking and human papillomavirus in laryngeal carcinoma: a Nordic prospective multicenter study
  • 2007
  • Ingår i: Journal of Cancer Research and Clinical Oncology. - Springer. - 1432-1335 .- 0171-5216. ; 133:9, s. 673-678

    • Purpose Human papillomavirus (HPV) has been linked to oropharyngeal carcinomas, but its role in laryngeal squamous cell carcinoma (LSCC) is not clear. A prospective multicenter study based on known tumor-cell percentage of fresh frozen carcinoma biopsies was established to determine the HPV prevalence. Moreover risk factors such as smoking, alcohol abuse, chronic laryngitis and gastroesophageal reflux disease (GERD) were evaluated Methods Fresh-frozen laryngeal cancer biopsies from 108 patients in Finland, Norway, and Sweden were investigated. Patients whose biopsy samples contained at least 20% tumor tissue (N = 69) entered the study. HPV DNA was determined with MY09/11 and GP5+/6+ nested PCR and SPF10 PCR hybridization assay. Patients were examined by an ENT specialist and an extensive questionnaire concerning risk factors was filled in. Results Only three patients (4.4%) harbored HPV DNA in their carcinoma sample. Heavy alcohol drinking was associated with an increased risk of death, advanced-stage disease, and younger age at diagnosis. Chronic laryngitis, GERD, and orogenital sex contacts were rare. Poor oral hygiene was not associated with survival, although it correlated with heavy drinking. Conclusion In our series HPV was not important in LSCC. Heavy drinking led to major mortality in LSCC and promoted early carcinogenesis.
