Figure 8. FLR reduces the occurrence of BCC and SCC in geriatric skin.

Figure 8

FLR treatment reduces the frequency of NMSCs arising from AKs as well as reduces the number of individuals who develop NMSCs. (A) Graphic representation of the location of BCC, SCC-in situ, and SCC identified on FLR-treated arms (n = 2) and untreated arms (n = 24). (B) The accumulation of verified NMSCs occurring on untreated and FLR-treated arms. (C) At each observation time point post-FLR treatment (3, 6, 9, 12, 18, 24, 30, and 36 months), the percentage of NMSCs that occurred out of the total number of AKs counted at the same time are shown for both untreated and FLR-treated arms. (D) At each time point described in C, the percentage of participants diagnosed with a NMSC is shown for both untreated and FLR-treated arms. For C and D, heavy black bars denote means and gray boxes indicate standard deviations. P values shown are derived from 2-tailed Student t test. (E) The cumulative total of participants who acquired more than 1 NMSC on their untreated arm. Thus far, no participant has more than 1 NMSC on their FLR-treated arm.
