Muranushi et al.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">1</span></a> carried out a meta-analysis with the aim of unifying and evaluating all current evidence on the relationship between NSAID use and cutaneous SCC. This study found, with statistical significance, that NSAID use reduces the risk of cutaneous SCC by 18% and that the use of nonaspirin NSAIDs reduces the same risk by 15%.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">2</span></a> The use of aspirin alone yielded similar percentages, but with borderline statistical significance.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">2</span></a> The decrease in risk is thought to be caused by the inhibition of COX-2 activity in promoting cutaneous carcinogenesis.</p><p id="par0015" class="elsevierStylePara elsevierViewall">The meta-analysis has multiple limitations, including the heterogeneity of the NSAID dosage measurements (which makes it impossible to analyze the relationship between dose and effect) and the failure to consider the confounding effect of sun exposure. Dosage is especially important in the study of aspirin because at low doses it would inhibit COX-1 and the preventive effect would be negligible but at high doses it would inhibit COX-2 and have an antitumor effect.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">2</span></a> In addition, the study considered NSAIDs as a group, despite the differences between their mechanisms of action, which are quite probably related to their preventive effects. The variability of the prevalence of NSAID use among the studies could reflect differences in the health status of the patients and, therefore, in their immune function. Collecting data on NSAID use is complex because patient interviews lead to greater memory bias in sporadic users, whereas prescription database searches do not detect people who use NSAIDs without a prescription.</p><p id="par0020" class="elsevierStylePara elsevierViewall">The synthesis of the data published to date therefore provides evidence for a significant inverse association between oral NSAID use and the incidence of cutaneous SCC, especially in patients with a high prevalence of actinic keratoses or a personal history of other keratinocytic tumors.<a class="elsevierStyleCrossRef" href="#bib0040"><span class="elsevierStyleSup">4</span></a> However, further studies that consider other confounding factors besides sun exposure—such as type of NSAID, dose, reason for use, etc.—are needed.
