Abstract

Background

Previous research has shown that certain treatment related adverse events correlate with clinical efficacy of targeted therapies in the treatment of patients with metastatic renal cell carcinoma (mRCC). A well-known class effect of mammalian target of rapamycin inhibitors is non-infectious pneumonitis. We evaluated the possible association of pneumonitis with outcomes in mRCC patients treated with everolimus.

Methods

303 consecutive patients with mRCC were treated in a single university hospital cancer center. We identified 85 patients (28.1%), who received sequential everolimus after first-line targeted therapy. Treatment-induced adverse events including pneumonitis were assessed and analyzed for the possible association with outcome using the Kaplan-Meyer method and Cox regression adjusted for known risk factors.

Results

33 patients (38.8%) developed clinical symptoms and radiological findings of pneumonitis during everolimus treatment. In univariate analysis patients with pneumonitis had both a longer overall survival (OS) (19.67 vs. 8.50 months; P 

Conclusions

Our results suggest that pneumonitis may be associated with everolimus treatment efficacy. Further validation studies are warranted to confirm our findings.
