Summary

This study tests whether a daily application of 5% niacinamide cream can prevent skin cancer in organ transplant recipients, who are at high risk due to long-term immune-suppressing drugs. Twenty adult transplant recipients with a history of precancerous skin spots and at least one prior skin cancer will use either the cream plus sunscreen or sunscreen alone for 12 months. Researchers will count skin spots and new cancers at 6 and 12 months to see if the cream offers extra protection.
