The number of patients who develop new NMSC in each arm will be documented. At this time, patients will be unblinded and all patients will receive Nicotinamide 500 mg BID for an additional year. At the end of this second year, patients will again undergo dermatologic examination, and the number of new NMSC will be quantified. The number of patients who develop NMSC will be documented. Skin biopsies will be taken for correlative studies.\n\nEnrollment will be split into two parts separated by an interim analysis. Part 1 will accrue 40 patients: 20 to each arm. After 40 patients have completed their 12 month visit an interim futility analysis will be conducted prior to recruiting more patients. The study will stop if the difference in the number of patients with NMSC between control and treatment arms is 0 or less (i.e., absolutely no evidence that the treatment is better than control).
