Abstract

Cutaneous squamous cell carcinoma (SCC) causes approximately 1,000,000 cases and 9000 deaths each year in the United States. While individual tumor sequencing studies have discovered driver mutations in SCC, there has yet to be a review and subsequent analysis synthesizing current studies. To conduct a comprehensive synthesis and analysis of SCC sequencing studies with individual patient-level data, a comprehensive literature search was performed. Statistical analyses were performed to identify trends. Studies meeting inclusion criteria included a total of 279 patients (189 localized SCCs, 90 metastatic SCCs). Several mutations were correlated with demographic characteristics (TP53, MLL4, BRCA2, COL4A1). TP53, TERT, SPEN, MLL3, and NOTCH2 mutations were significantly more likely to be found in metastatic versus localized SCCs even after the Bonferroni correction for multiple comparisons. Silent mutations were found more in localized SCCs than metastatic SCCs, and nonsense mutations were found more in metastatic SCCs than localized SCCs (p = 0.0003 and p = 0.04, respectively). Additional mutations were identified that have not yet been explored in SCC including AHNAK2, LRP1B, TRIO, MDN1, COL4A2, SVIL, VPS13C, DST, DMD, and DYSF. Overall, novel mutations were identified and differences between mutation patterns in localized and metastatic SCCs were found. These findings may have clinical applications.
