Staging and Prognostic Factors in High-Risk Cutaneous Squamous Cell Carcinoma
Description
The presentation by Katie Swozi discusses the staging and prognostic factors of high-risk cutaneous squamous cell carcinoma (SCC). It reviews two primary staging systems: the AJCC 8 and the Brigham and Women's system. The AJCC 8 refined tumor classifications based on size and histological factors, highlighting that T3 and T4 tumors predict poor outcomes. The Brigham and Women's system emphasized the importance of histology in risk stratification, distinguishing between T2A and T2B categories, which helps to better identify patients who may require more aggressive treatment. Additional risk factors for high-risk SCC were examined, including clinical and histologic features like tumor size, perineural invasion, and histologic subtype. The discussion also touched on novel histologic scoring systems for perineural invasion that could enhance prognostic capabilities. Gene expression profiling was briefly mentioned as an emerging tool for risk stratification. Overall, accurate staging and a comprehensive assessment of risk factors are essential for predicting outcomes and guiding treatment decisions in patients with high-risk cutaneous SCC.

- Accurate staging is critical for predicting patient outcomes in cutaneous squamous cell carcinoma (cSCC).
- AJCC 8 provides refined categorization of tumors compared to AJCC 7, identifying more high-risk tumors.
- The incorporation of histological factors, such as tumor differentiation and perineural invasion, enhances risk stratification.
- Brigham and Women's Hospital (BWH) staging system offers better differentiation between T2A and T2B tumors compared to AJCC 8.
- Patients in the T2B group face a significant risk of local recurrence and nodal metastasis, necessitating further treatment.
- Histopathologic factors like tumor invasion depth and the extent of perineural invasion significantly correlate with adverse outcomes.
- A newly proposed scoring system for perineural invasion could provide a more objective assessment of risk.
- Gene expression profiling (GEP) is a valuable third category of risk stratification that complements traditional staging systems.
- Identifying high-risk features early can improve patient management strategies and outcomes in cSCC.
