Nicotinamide as a Preventive Treatment for Skin Cancer

Nicotinamide (vitamin B3) treatment for 12 months was found to be associated with a reduction in rate of new skin cancers, an Australian study has found.

 

A study published in the New England Journal of Medicine has investigated whether nicotinamide (vitamin B3) can be used as a treatment to prevent skin cancer, since research has demonstrated protective effects of nicotinamide against UV damage. A total of 386 participants were included in the clinical trial, who had previously been diagnosed with a minimum of two non-melanoma skin cancers. The participants were randomly assigned to receive either 500mg of nicotinamide twice per day, or placebo.

The study reported a 23% reduction in rate of non-melanoma skin cancers in participants who had taken nicotinamide, compared with participants who did not take nicotinamide. Reductions in the rate of basal-cell carcinomas, squamous-cell carcinomas, and actinic keratosis were also noted in the nicotinamide treatment group, compared with the placebo group.

The researchers conclude that in this high-risk population of patients, who had previously been diagnosed with non-melanoma skin cancer, nicotinamide was safe and effective at reducing the occurrence of both non-melanoma skin cancers, and actinic keratoses.
