Background:
Patients with dyskeratosis congenita (DC) have an increased risk of cancer, but also exhibit heightened radiation sensitivity. Proton therapy improves sparing of normal tissue, and thus may reduce radiation toxicity in patients with DC.
Observations:
We present a pediatric patient with DC who was treated with adjuvant proton therapy for oropharyngeal cancer. He experienced more severe skin toxicity and mucositis than expected. With reduced fractions per week and extensive supportive care, he completed the full radiation course.
Conclusions:
Proton therapy can improve normal tissue sparing, allowing successful delivery of radiation therapy in DC patients.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
