IMPORTANCE: Risk stratification of cutaneous squamous cell carcinoma (CSCC) is central to effective management. Despite advancements in the 8th edition of the American Joint Committee on Cancer (AJCC8) staging system, the distinctiveness of T-stages remains limited.
OBJECTIVE: To evaluate the effectiveness of the Brigham and Women's Hospital (BWH) and the AJCC8 staging systems in predicting poor outcomes in head and neck (HN) CSCC.
DESIGN: A retrospective, multinational cohort study of CSCCs diagnosed between January 10, 1991, and December 31, 2023.
SETTING: Twelve centers across the United States (10), Spain (1), and Brazil (1).
PARTICIPANTS: Patients with invasive CSCC who underwent curative-intent surgical treatment. Exclusions included cases of lip CSCC, cases with prior HN cancer with associated regional disease, patients with a history of chemotherapy/radiotherapy for other HN neoplasms, and recurrent primary tumors.
EXPOSURE: Tumors were staged according to both the AJCC8 TNM staging system and the BWH tumor classification.
MAIN OUTCOMES AND MEASURES: Local recurrence (LR), nodal recurrence (NR), distant recurrence (DR), and disease-specific death (DSD).
RESULTS: A total of 9852 excised tumors from 3168 patients were included. The 2 systems had comparable monotonicity and homogeneity. Significant differences could be observed in 5-year cumulative incidence for DSD in both BWH and AJCC8, and also for LR in BWH. Higher T-stages exhibited similar curves regarding NR and DR for both AJCC8 and BWH staging systems. Overall, we observed high specificity and NPV, low sensitivity and PPV, and moderately high c-indices for both the BWH and AJCC8 staging systems in predicting the main outcomes for HNCSCC.
CONCLUSION AND RELEVANCE: Current AJCC8 and BWH staging systems can accurately predict survival in HNCSCC, although there are still important characteristics to be addressed in future staging systems for better stratification according to the other main outcomes.
