Summary
This study identifies key factors for lymph node metastasis in lip squamous cell carcinoma (SCC). A new prediction model accurately identifies high-risk patients, aiding treatment decisions for lip SCC.
Area of Science:
- Oncology
- Dermatology
- Head and Neck Surgery
Background:
- Squamous cell carcinoma (SCC) of the lip presents a higher risk of lymph node metastasis (LNM) compared to other head and neck cutaneous SCCs.
- Accurate prediction of LNM is crucial for effective management of lip SCC patients.
Purpose of the Study:
- To identify predictive factors for lymph node metastasis (LNM) in lip squamous cell carcinoma (SCC).
- To develop and validate a prediction model for stratifying lip SCC patients based on LNM risk.
Main Methods:
- Retrospective analysis of tumor characteristics in 326 lip SCC patients.
- Binary logistic and Cox regression analyses were employed to identify predictive factors and build the LNM model.
Main Results:
- Lymph node metastasis (LNM) was observed in 8% of patients.
- Tumor extent, depth, and grading were significant predictors of LNM, achieving 94.2% classification accuracy.
- The developed prediction model, using tumor depth and grading, effectively stratified patients into high and low LNM risk groups.
Conclusions:
- A novel, accurate prediction model for LNM in lip SCC has been developed.
- This model facilitates the identification of high-risk patients, supporting decisions regarding lymph node dissection in lip SCC management.
