Patients with high neutrophil-to-lymphocyte ratio (NLR) and large tumors face higher risks of progressive disease (PD) during immune checkpoint inhibitor (ICI) therapy for head and neck cancers. These factors also predict poorer overall survival outcomes in R/M HNSCC patients.
Area of Science:
- Oncology
- Immunotherapy
- Head and Neck Cancer Research
Background:
- Investigating clinical features of patients with recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC).
- Focusing on patients who experienced progressive disease (PD) after receiving immune checkpoint inhibitor (ICI) therapy.
Purpose of the Study:
- To analyze clinical factors associated with treatment outcomes in R/M HNSCC patients post-ICI therapy.
- To identify predictors of progressive disease and overall survival in this patient cohort.
Main Methods:
- Retrospective analysis of 256 R/M HNSCC patients from 11 medical centers.
- Evaluation of associations between clinical factors and treatment outcomes: best response, overall survival, and progression-free survival.
Main Results:
- Objective response rate was 19.5%; 50.4% experienced progressive disease (PD).
- High neutrophil-to-lymphocyte ratio (NLR > 4) and large tumor size (> 40 mm) were significant risk factors for PD.
- High NLR, poor performance status (ECOG PS 2-3), and large tumor size independently predicted poor overall survival.
Conclusions:
- Elevated NLR and larger tumor size are key indicators of higher risk for PD during ICI therapy.
- These factors also correlate with diminished overall survival in R/M HNSCC patients undergoing ICI treatment.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
