Deadly Skin Cancer More Common in Organ Transplant Recipients
“We knew that melanoma was more likely in transplant recipients, but we thought it might be a function of intensive screening since they are very likely to develop less deadly forms of skin cancer and are checked regularly by dermatologists,” study leader Hilary Robbins, a Ph.D. student in the department of epidemiology at Johns Hopkins Bloomberg School of Public Health in Baltimore, said in a university news release.
“To the contrary, we were surprised to see that transplant recipients were particularly at risk for developing melanomas that weren’t found until they had already spread,” she added.
In addition, the risk of aggressive melanoma was especially high within the first four years after transplant, the study found.
The findings were published recently in the Journal of Investigative Dermatology.
The findings suggest a link between organ transplants and melanoma risk; they don’t prove cause-and-effect.

Transplant candidates should undergo careful screening for skin cancers before they receive a transplant, the researchers said. It’s possible that some melanomas may be present at the time of transplant and begin to spread aggressively when patients start taking immunosuppressive drugs, Robbins noted.
Close monitoring for melanoma after a transplant is also important so that the disease can be caught at an earlier, more treatable stage, she added.
