Summary

This summary is machine-generated.

Adjuvant pembrolizumab showed 64.2% disease-free survival in real-world renal cell carcinoma patients. However, M1NED patients had higher recurrence rates and earlier onset compared to clinical trials.

Area Of Science

  • Oncology
  • Nephrology
  • Clinical Trials

Background

  • Adjuvant pembrolizumab demonstrated improved disease-free survival (DFS) in high-risk renal cell carcinoma (RCC) patients post-nephrectomy in the KEYNOTE-564 trial.
  • Real-world data is crucial to validate findings from clinical trials in diverse patient populations.

Purpose Of The Study

  • To evaluate the efficacy and safety of adjuvant pembrolizumab in a real-world RCC cohort.
  • To compare real-world outcomes with those reported in the KEYNOTE-564 trial.

Main Methods

  • Multicenter retrospective study including RCC patients receiving adjuvant pembrolizumab from January 2022 to October 2023.
  • Assessment of disease-free survival (DFS) and treatment safety, including adverse events and treatment discontinuations.

Main Results

  • Fifty-two RCC patients were included, with varying risk classifications (intermediate-high risk, high risk, M1 with no evidence of disease).
  • Overall DFS at 6 months was 64.2%. M1NED patients showed significantly lower DFS compared to non-metastatic patients (p = 0.025).
  • Grade 3 or higher adverse events occurred in 26% of patients, with 20% discontinuing treatment.

Conclusions

  • Real-world recurrence rates in M1NED patients were high and occurred earlier than observed in the KEYNOTE-564 trial.
  • Long-term toxicities associated with adjuvant pembrolizumab were comparable to clinical trial data.
  • Adjuvant pembrolizumab demonstrates a potential benefit in real-world RCC settings, though careful monitoring for M1NED patients is warranted.
