Abstract
BACKGROUND: Porphyria is a condition of cutaneous photosensitivity. It is unclear if radiotherapy (RT) is safe in patients with porphyria.
METHODS: We report a patient case with uncontrolled porphyria cutanea tarda treated with chemoradiation for p16-positive oropharyngeal cancer. Given the scarcity of data on this subject, we also conducted a literature review on the topic of radiation in patients with porphyria.
RESULTS: The patient in our study did not experience any unusual acute or late toxicity, despite receiving a high dose of cutaneous radiation. We also found the majority of the literature supports the safe use of therapeutic radiation in patients with porphyria.
CONCLUSION: In this patient, and in the majority of the literature, radiation seems safe in patients with porphyria; however, there are few reports on the subject in the literature, therefore, caution is warranted.
