XP-Patienten haben ein hohes Risiko für schwere Sonnenbrände, Hauttrockenheit, fortschreitende Pigmentstörungen, vorzeitige Lichtalterung und ein dramatisch erhöhtes Auftreten von bösartigen Hauttumoren in UV-exponierten Bereichen wie Gesicht, Hals und Kopf.<span><sup>1-3</sup></span> Das Risiko, an Hautkrebs zu erkranken, ist bei XP-Patienten im Vergleich zur Allgemeinbevölkerung bis zu 10 000-mal höher für nichtmelanozytäre Hauttumoren (<i>non-melanoma skin cancers</i>; NMSC) wie Basalzellkarzinome und kutane Plattenepithelkarzinome (<i>cutaneous squamous cell carcinomas</i>; cSCC); die Inzidenz von Melanomen ist Berichten zufolge 2000-mal höher. Andere Hauttumoren wie Keratoakanthome, Talgdrüsenkarzinome, Fibrosarkome und Angiosarkome treten ebenfalls häufiger auf. Patienten mit XP, die an Hautkrebs erkranken, neigen zu aggressiveren Malignomen mit einem höheren Risiko der Metastasierung und des krebsbedingten Todes. Das mittlere Sterbealter bei XP-Patienten liegt bei 32 Jahren, wobei 60% der Todesfälle vor dem 20. Lebensjahr auftreten.<span><sup>4-6</sup></span> Studien zeigen, dass XP-bedingter Hautkrebs eine 3,6-fach höhere Mutationslast als sporadischer Hautkrebs aufweist.

Die mittlere Tumormutationslast (TMB) für einzelne Basensubstitutionen in bestimmten XP-Gruppen kann bis zu 350 Mutationen pro Megabase erreichen.
