Objective:

To evaluate the efficacy of PD-1/PD-L1 inhibitors in patients with recurrent or metastatic nasopharyngeal carcinoma (NPC) and their potential impact on survival outcomes.

Key Findings:
  • Median progression-free survival (PFS) was 4.21 months.
  • Median overall survival (OS) was 16.27 months.
  • 1-year PFS rate was 43%, and 1-year OS rate was 80%.
  • Pooled objective response rate (ORR) was 45%, and disease control rate (DCR) was 65%.
  • Adverse events occurred in 90% of patients, with 34% experiencing grade 3 or higher events, indicating significant safety concerns.
Interpretation:

The findings suggest a potential improvement in ORR and DCR in recent studies, possibly due to refined patient selection and enhanced treatment strategies, although definitive conclusions require more high-quality evidence.

Limitations:
  • Predominance of single-arm studies.
  • Small sample sizes in several cohorts.
  • Heterogeneity across treatment regimens, dosing, and patient characteristics, which may affect the reliability of the results.
Conclusion:

The study enriches the existing evidence but highlights the need for robust, high-quality trials to draw definitive conclusions about the efficacy and safety of PD-1/PD-L1 inhibitors in NPC.
