Cancer drug causes loss of fingerprints
A cancer patient was detained for four hours by immigration officials in the US because one of his cancer drugs had caused his fingerprints to disappear. As a result, his oncologist has advised that all cancer patients receiving capecitabine should carry a doctor's letter when travelling to the US. The 62-year-old patient had metastatic nasopharyngeal carcinoma that had responded well to chemotherapy; he was put on a maintenance dose of capecitabine to help prevent recurrence. A potential side-effect of the drug is hand-foot syndrome, chronic inflammation of the palms or soles that can result in skin peeling and the development of ulcers or blisters, which can lead to eradication of fingerprints.
