Response to 'The incidence and survival of melanoma and nonmelanoma skin cancer in patients with vitiligo: a nationwide population-based matched cohort study in Korea': reply from authors. Br J Dermatol. 2020 Aug 07;: Authors: Kim HS, Ahn HS Abstract It is technically impossible to ascertain cumulative UVR exposure with the Korean National Health Insurance claims database due to the lack of information on each treatment dose. As an alternative, we stratified our patients based on the number of phototherapy sessions (no phototherapy, <50, 50 or more sessions) to find no association between phototherapy sessions and the risk of skin cancer. This is in line with the findings from Jorgensen et al.,1 which suggest that cumulative UVR exposure is not a significant confounder. PMID: 32767749 [PubMed - as supplied by publisher]
