It includes basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Its main risk factors are accumulated exposure to sunlight, immunosuppression, and infection with the beta human papillomavirus. The use of topical sunscreen is frequently indicated in secondary prevention. In recent years, new evidence supports the use of some drugs as chemoprophylactics (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>).</p><elsevierMultimedia ident="tbl0005"></elsevierMultimedia><p id="par0010" class="elsevierStylePara elsevierViewall">A randomized double-blind clinical trial in 932 high-risk patients (98% Caucasian males, with a mean age of 71 years) was recently published. Chemoprevention was studied using a cycle of 5% topical fluorouracil (every 12<span class="elsevierStyleHsp" style=""></span>h for 4 weeks) (n<span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>468) versus placebo (n<span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>464) on the appearance of NMSC of the face and ears with surgical indication. In the first year after treatment a lower number of SCC was detected (1% versus 4%) (risk reduction of 75% [95% CI, 35%–91%] [<span class="elsevierStyleItalic">P</span><span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>.002]). No differences were found in BCC (10% versus 11%), although the number of Mohs surgeries in the first year dropped. After 4 years of follow-up, no differences were found in the number of SCC or BCC between the 2 groups (39% versus 38%). In terms of adverse effects, 92% of the group receiving fluorouracil presented erythema (21% described it as severe), but 85% would use the treatment again if necessary.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">1</span></a> These results suggest that a cycle of topical fluorouracil would be useful in secondary prevention of SCC for a year. It remains to be demonstrated whether an annual cycle of 5% topical fluorouracil is an effective long-term strategy. We must remember that 5-fluoracil is not sold in Spain and must be formulated. This may limit its potential use in Spain.</p><p id="par0015" class="elsevierStylePara elsevierViewall">Previously, a phase-III randomized, double-blind, placebo-controlled clinical trial in 386 high-risk patients had demonstrated the efficacy of oral nicotinamide (500<span class="elsevierStyleHsp" style=""></span>mg/12<span class="elsevierStyleHsp" style=""></span>h of vitamin B3) as chemoprevention for NMSC. In the 12 months that the nicotinamide was used, the number of NMSC per person was reduced (1.8 versus 2.4), with a risk reduction of 23% (95% CI, 4%–38%) (<span class="elsevierStyleItalic">P</span><span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>.02), and the drug was well tolerated.

Most of the above-mentioned treatments have demonstrated efficacy in preventing SCC but not BCC. This may be explained by their different etiologies, including the fact that UV radiation damage and viral infection are not as important in BCC. In terms of treatment of NMSC precursor lesions, different topical agents have been shown to be effective, such as ingenol mebutate, imiquimod, and diclofenac. Photodynamic therapy is also highly effective in the treatment of these lesions.</p><p id="par0030" class="elsevierStylePara elsevierViewall">In solid-organ transplant and immunosuppressed patients, it is important to reduce immunosuppression to the minimum effective dose and to replace calcineurin inhibitors (cyclosporin and tacrolimus) with mTOR inhibitors (sirolimus or everolimus).
