Role of human papillomavirus in cutaneous squamous cell carcinoma: A meta-analysis - 14/03/14
Abstract |
Background |
The role of human papillomavirus (HPV) in cutaneous squamous cell carcinoma (cuSCC) is not well defined, with past studies showing conflicting results.
Objective |
We sought to determine if there is a significant association between HPV and cuSCC and whether cuSCC from immunosuppressed patients are more likely to carry HPV than cuSCC from immunocompetent patients.
Methods |
We performed a systematic review and abstracted data from articles that included: skin samples by biopsy, HPV detection by polymerase chain reaction, and a minimum of 10 cases and 10 controls. Pooled effect size and 95% confidence intervals were calculated using random effects meta-analysis using the inverse variance method.
Results |
cuSCC were more likely to carry HPV than normal-appearing skin (pooled effect size [ES] 3.43, 95% confidence interval 1.97-5.98, P < .0001) in all patients. An increase in HPV prevalence was found in tumors from immunosuppressed patients compared with immunocompetent patients (pooled ES 3.01, 95% confidence interval 2.00-4.52, P < .0001).
Limitations |
The greatest limitation is the heterogeneity of the studies included. The association of higher HPV prevalence in squamous cell carcinoma compared with normal-appearing skin does not imply causality.
Conclusion |
These results contribute to evidence that HPV is associated with cuSCC. Higher HPV burden in tumors from immunosuppressed patients compared with immunocompetent patients may have therapeutic implications.
