<br/><br/> Background : 8 - Oxoguanine is one of the major products of DNA oxidation . It is considered a key parameter in the mutagenic and carcinogenic effect of ultraviolet radiation in humans . Objective : To assess and compare the carcinogenic potential of different photo (chemo) therapeutic modalities (namely NBUVB , PUVA and BB-UVA)in a variety of skin diseases by measuring 8 - oxoG level in dark - skinned individuals before and after photo (chemo) therapy
