Objective:

To evaluate the efficacy of neoadjuvant chemoimmunotherapy compared to neoadjuvant immunotherapy alone in patients with resectable head and neck squamous cell carcinoma (HNSCC).

Key Findings:
  • Pooled MPR plus CPR rates were 66% for chemoimmunotherapy, 18% for dual-agent immunotherapy, and 6% for single-agent immunotherapy.
  • CPR rates were 38%, 5%, and approximately 3% for the respective treatment groups.
  • Radiographic response rates favored chemoimmunotherapy with 66% showing partial or complete responses compared to 9% and 6% for dual-agent and single-agent immunotherapy, respectively.
  • Adverse events (grade 3 to 5) occurred in 17% of patients receiving chemoimmunotherapy, 3% for dual-agent, and 29% for single-agent immunotherapy.
Interpretation:

Limitations:
  • Many included trials were single-group studies, limiting direct comparisons.
  • High heterogeneity across chemoimmunotherapy trials.
  • Subgroup analyses by disease subsite, stage, or HPV status could not be performed.
  • Inconsistent reporting of survival outcomes and adverse events.
Conclusion:
