Non-melanoma skin cancer and NSAID use in women with a history of skin cancer in the Women's Health Initiative. Preventive medicine Wysong, A., Ally, M. S., Gamba, C. S., Desai, M., Swetter, S. M., Seiffert-Sinha, K., Sinha, A. A., Stefanick, M. L., Tang, J. Y. 2014; 69: 8-12

Abstract

Evidence for the effect of non-steroidal anti-inflammatory drugs (NSAIDs) on non-melanoma skin cancer (NMSC) risk is inconsistent. We prospectively examined whether regular, inconsistent, or no/low-use of NSAIDs is associated with lower NMSC risk among 54,728 postmenopausal Caucasian women in the Women's Health Initiative Observational Study enrolled between 1993 and 1998.Logistic regression models were used to assess odds of NMSC after adjusting for skin type, sun exposure history and indication for NSAID use.There were 7652 incident cases of NMSC (median follow-up: 6.9years). There was no association between regular NSAID-use and NMSC risk relative to no/low-users. However, in a subgroup analysis of 5325 women with a history of skin cancer (incident NMSC: 1897), odds of NMSC were lower among regular NSAID users whether <5years (OR 0.82, 95% CI: 0.70-0.95) or =5years (OR 0.82, 95% CI: 0.69-0.98) of use compared to no/low-users. Inconsistent NSAID use and acetaminophen use were not associated with NMSC risk.Overall, NSAID use was not associated with NMSC risk. However, in women with a history of skin cancer, regular NSAID use was associated with 18% lower odds of NMSC. Future studies on potential chemopreventative effects of NSAIDs should focus on subjects with prior history of NMSC.
