Clinical Scorecard: Defining Lymph Node Dissection Adequacy Thresholds Following Neoadjuvant Immunochemotherapy: A Surgical Standard for Survival in Oral Squamous Cell Carcinoma
At a Glance
Category
Detail
Condition
Key Mechanisms
Neoadjuvant immunotherapy combined with chemotherapy (NICT) and lymph node dissection (LND) adequacy thresholds.
Target Population
Care Setting
Key Highlights
Optimal LND thresholds: 20 total lymph nodes for unilateral dissections and 18 nodes per side for bilateral dissections.
Inadequate LND associated with worse overall survival (OS) and disease-free survival (DFS).
Higher risk of major complications linked to inadequate LND in unilateral dissections.
Guideline-Based Recommendations
Diagnosis
Management
Achieve a yield of ≥20 nodes in unilateral dissection.
Achieve an average of ≥18 nodes per side in bilateral dissection.
Monitoring & Follow-up
Risks
Inadequate LND linked to increased risk of major complications.
Patient & Prescribing Data
256 patients in training cohort and 199 patients in validation cohort.
