Summary
This summary is machine-generated.Sentinel lymph node biopsy (SLNB) improves survival for head and neck cutaneous squamous cell carcinoma (HNcSCC) patients with high-risk factors. This study recommends SLNB for patients with two or more risk factors to enhance outcomes.
Area Of Science
- Oncology
- Surgical Oncology
- Dermatology
Background
- Head and neck cutaneous squamous cell carcinoma (HNcSCC) management requires careful risk stratification.
- Sentinel lymph node biopsy (SLNB) is increasingly considered for staging clinically node-negative (cN0) HNcSCC.
- The oncologic benefit of SLNB versus observation in high-risk cN0 HNcSCC remains under investigation.
Purpose Of The Study
- To compare oncologic outcomes between observation and SLNB in cN0 high-risk HNcSCC patients.
- To evaluate the impact of SLNB on disease-specific survival (DSS) and overall survival (OS).
- To identify patient subgroups who benefit most from SLNB.
Main Methods
- Retrospective analysis of the SEER database.
- Inclusion of 9804 patients with cN0 high-risk HNcSCC.
- Propensity Score Matching (PSM) analysis to compare observation versus SLNB outcomes.
- Multivariate analysis to assess SLNB as an independent predictor of survival.
Main Results
- SLNB was an independent predictor of improved DSS (HR 0.70).
- SLNB showed better DSS in patients with 2-3 high-risk factors (p=0.021, p=0.044) but similar OS.
- SLNB significantly improved both DSS (p=0.040) and OS (p=0.028) in patients with four high-risk factors compared to observation.
Conclusions
- SLNB is a feasible and beneficial technique for HNcSCC management.
- SLNB significantly improves DSS and OS in high-risk HNcSCC patients, particularly those with four risk factors.
- SLNB is recommended for patients with two or more high-risk factors to guide treatment and improve outcomes.
