What first-line therapeutic regimen do you consider most appropriate for metastatic clear cell renal carcinoma presenting with brain metastasis and vasogenic edema?

For patients presenting with brain metastases, I always do local therapy, usually SBRT, before systemic therapy. I am nervous about starting immune-based therapy or a TKI in patients with uncontrolled CNS metastases. There are small series using TKIs such as cabozantinib in this setting, but since S...

The presence of vasogenic edema indicates symptomatic or mass–effect–producing brain metastases requiring urgent intervention. Dexamethasone should be initiated promptly, using the lowest effective dose for the shortest duration, with BID or once-daily dosing recommended (typically 4–8 mg/day, titra...

Yes, it is safe, but I always treat the CNS metastasis first (e.g., SRS). The risk of bleeding in an untreated CNS metastasis with a VEGF TKI is otherwise unacceptable in my opinion. The edema should be treated with steroids as appropriate, and I haven't experienced TKIs worsening CNS edema.

Management of brain metastases should be a multidisciplinary discussion that includes neurosurgery and medical oncology. Upfront resection of large lesions is preferred due to the radioresistant nature of RCC when feasible for patients with favorable KPS and life expectancy. In these settings, I wou...
