PICO question

In cats infected with papillomavirus, is the risk of developing feline cutaneous squamous cell carcinoma greater than cats that are not infected with papillomavirus?


Clinical bottom line

Category of research question


The number and type of study designs reviewed

Eleven papers were critically reviewed, nine were case-control studies and two were experimental in vitro studies

Strength of evidence


Outcomes reported

Infection of feline epithelial skin cells with Felis catus papillomavirus type 2 (FcaPV-2) is a risk factor for the development of feline cutaneous squamous cell carcinoma. The pathogenesis of FcaPV-2 infection and neoplastic transformation into malignant cells shares similar pathways to the human papillomavirus (HPV) model of pathogenesis and carcinogenesis with some differences


In conclusion, there is moderate strength of evidence in the literature to support a role of FcaPV-2 in the development of cutaneous squamous cell carcinomas in cats. Therefore, prevention of infection with FcaPV-2 should prevent some cancers


How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
