Abstract excerpt
The mechanism underlying the progression of actinic keratosis (AK) and cutaneous squamous cell carcinoma (SCC) in situ (SCCIS) to SCC remains unclear. To investigate this, we performed regional microdissection and targeted deep sequencing in SCC (n = 10) and paired adjacent sun-damaged epidermis (SE)/AK/SCCIS (n = 13) samples to detect mutations and copy number alterations. Most (11/13) SE/AK/SCCIS tissues...
