Abstract:
Cabozantinib represents an established vascular endothelial growth factor- (VEGF-) tyrosine kinase inhibitor (TKI) in the treatment paradigm of metastatic renal cell carcinoma (mRCC). Its activity in mRCC patients with brain metastases (BMs) has been largely underreported in prospective clinical trials. We present the unique case of a heavily pretreated mRCC patient with BMs who achieved a brain complete response to cabozantinib prior to receiving radiation therapy. We end with a literature review and discussion of the biologic rationale and growing evidence supporting the intracranial activity of cabozantinib.
Insights
Cabozantinib, a VEGF tyrosine kinase inhibitor, showed a complete response in the brain for a heavily pretreated metastatic renal cell carcinoma patient with brain metastases. This highlights its potential intracranial activity.
Area of Science:
- Oncology
- Medical Research
Background:
- Cabozantinib is an established vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI) for metastatic renal cell carcinoma (mRCC).
- Its efficacy in mRCC patients with brain metastases (BMs) is underreported in prospective trials.
