Supplemental Table 2: Rates of poor outcomes in primary, non-metastatic CSCC stratified by BWH and AJCC 8 stage in the overall cohort

This table display the rates of poor outcomes stratified by tumor stage for all primary, non-metastatic tumors that underwent curative therapy in this multi-center, multinational cohort of cutaneous squamous cell carcinomas. The rates of local recurrence, nodal metastasis, satellitosis/in-transit metastasis, distant metastasis, and disease-specific death increased significantly with higher tumor stage using both Brigham & Women’s Hospital (BWH) and American Joint Committee on Cancer 8th edition (AJCC 8) staging systems.
