What's New in Melanoma
I am seeing increasing numbers of melanoma in my practice, with two cases in one day recently. One relatively simple agent that may improve survival is vitamin D. A recent prospective cohort study of 1,042 melanoma patients by Fang et al found that those with higher vitamin D values had significantly higher “overall survival, melanoma-specific survival, and disease-free survival.” Those with < 16 ng/ml, the approximate value used to mark Vitamin D deficiency, “were 1.62 times more likely to experience recurrence and were 1.76 times more likely to die as a result of melanoma.”
That being said, the study does not prove cause and effect. I would also emphasize I would not recommend increasing sun exposure to increase vitamin D levels. The consensus is oral supplementation is much preferred over increasing sunlight exposure. In addition, vitamin D is not risk free and can lead to excessive calcium levels (“particularly in high dosages of >5000 IU daily”)
While further data and guidelines would be ideal, those who have been diagnosed with melanoma or are at high risk for melanoma may wish to consider vitamin D blood level testing and/or supplementation.
If you have bumps on your body worrisome for skin cancer, especially melanoma, or have other skin questions, please make an appointment for dermatology consultation at (626) 331-6411 to discuss your options.
