During AS, the best overall responses were stable disease for 48 patients (83 %) and progressive disease (PD) for 10 patients (17 %), and 47 patients
With a median follow-up of 31.4 months, the
median TTP was 12.4 months (95 % confidence interval
8.4–16.5) and median overall survival was not reached
Karnofsky performance status <100 %, liver metastasis, and a time from diagnosis to AS of less
than 1 year were found to be predictive factors for a shorter TTP

Surveillance in Metastatic RCC

CASE DISCUSSION

patient is asking about the need to start therapy 3 yrs after
nephrectomy

First-Line Treatment Considerations for RCC: Summary
 Multiple good systemic therapy options for metastatic RCC, with no obvious
clear choice in some cases
 Good-risk patients, and those with “favorable intermediate” risk, can have
survival of many yrs—with and without therapy
 Consider debulking nephrectomy and/or active surveillance in selected patients
Patients with:
• IMDC intermediate/poor-risk
disease
• No significant autoimmune
disease
• VEGF contraindications
• A need to avoid chronic
VEGF AEs
Consider
Nivo + Ipi
Patients with
• IMDC favorable- or
intermediate-risk disease
• Intermediate- or poor- risk
disease who need rapid
response
• A need to avoid irAEs associated
with dual IO therapy
Consider
Pembro +
Axitinib

CASE DISCUSSION

Considerations for Next-Line Treatment Selection
 If disease control > 1 yr on first-line single-agent VEGF inhibitor, continue VEGF
inhibition with sequential single agents: such as Cabozantinib or Axitinib
 If brief response to single-agent VEGF inhibition, consider a VEGF IO combination:
Axitinib + Pembrolizumab (based on Lenvatinib + Pembro data)
 If no response to first-line VEGF inhibition, drop VEGF and switch to
immunotherapy: Ipilimumab + Nivolumab or Nivolumab
 If no response to combination VEGF + IO switch to second line VEGF such as
Cabozantinib or Axitinib or Lenvatinib + Everolimus
‒ Phase III data support sequential VEGF therapy
‒ Limited data to support sequential IO therapy

EVEROLIMUS COMBINATION IN THE
MANAGEMENT OF mRCC?
