Objective:

To provide experience on off-label belzutifan treatment in patients with advanced VHL-associated tumors where existing therapies posed a risk of compromising organ function or were ineffective, particularly in cases of severe organ dysfunction.

Key Findings:
  • Belzutifan demonstrated efficacy in managing advanced VHL-associated tumors, suggesting a shift in treatment paradigms.
  • Patients faced high risks with conventional surgical options due to organ dysfunction, highlighting the need for alternative therapies.
  • The treatment was classified as a last-line, organ-preserving option, indicating its critical role in patient management.
Interpretation:

Belzutifan may provide a valuable alternative for patients with advanced VHL-associated tumors, particularly when traditional interventions are not viable, underscoring the necessity for further research.

Limitations:
  • Retrospective nature of the study limits generalizability and introduces potential biases.
  • Small sample size and lack of formal quality-of-life assessments may affect the robustness of the findings.
Conclusion:

Belzutifan represents a promising off-label treatment option for patients with advanced VHL-associated tumors, warranting further investigation.
