metastatic RCC
Presented by :
Ass. Lecturer : HebatAllah Mahmoud Bakri
AUH
JAN- 2021

Agenda : 1st part rapid look
- Epidemiology
- Pathology and its relation to survival
- Causes ( genetics ) & risk factors
- clinical picture
- Staging , risk stratification and its relation to survival
- Treatment of RCC in the adjuvant setting

Agenda 2nd part : to answer the following
questions
• Is there a role of nephrectomy in m.Rcc ??
• Are we dare enough to put m.RCC patient on active surveillance ??
• Is there any difference between TKIs in 1st line in m.RCC ?
• What are 2nd options in refractory or relapsed m.RCC ??

Agenda 3rd part : 2020 hope
• Imm.oncology in m.RCC is it a new standard of care ???
• ESMO & ASCO GU updates in 2020 -----
• Wrap up and conclusion

Epidemiology
• (RCC) accounts for 3% of adult solid tumors with growing incidence in
recent decades.
• More than 25% of patients metastatic disease at the time of
diagnosis and about 20–30% will develop metastases during follow
up after surgery for localized disease

Causes of kidney cancer
• We don’t know the full story , but we understand a few pieces of the
puzzle, especially for more common forms of the disease.
• In most cases, kidney cancer begins when there are mutations in
certain genes that normally keep cell division in check.
For example, people with clear cell renal cell carcinoma often have a
mutation that causes extra blood vessels to grow inside the kidney.

• Most kidney cancer patients acquire these mutations over their
lifetime, meaning they’re born with perfectly healthy genes
• Notably, these changes usually occur in conjunction with other factors
before cancer shows up.

• Other people inherit certain conditions .
Here are a few of those inherited disorders:
• Von Hippel-Lindau disease
• Hereditary papillary renal carcinoma
• Birt Hogg-Dubé (BHD)
• Hereditary leiomyoma (HLRCC)
• Succinate dehydrogenase deficiency
• Tuberous sclerosis
• PTEN hamartoma tumor syndrome (including Cowden syndrome)

When to consider genetic counselling ?
• If patient is diagnosed before 47 y.o
• If tumors on both kidneys
• If patient have a family history of kidney cancer
• If the patient have any of the previous inherited diseases

Risk factors of kidney cancer
• male sex : 60 % cases are male
• Age > 55
• Habit : smoking increase risk 20 %
• Wight : obesity increase risk 20 – 30 %
• Disaeses : High Blood Pressure – Chronic Kidney Diseases .

Pathological subtypes of RCC :

Stage and survival
• Stage I – Survival more than 90 percent
• Stage II – between 75 to 95 percent
• Stage III – between 60 to 90 percent depending on
nephrectomy status and size of tumor
• Stage IV – Median survival between 28 to 30 months, which
varies according to risk group

1- Is there a role of nephrectomy and
metastatectomy in m.RCC ???

CARMENA: Prospective, Multicenter, Open-Label,
Randomized Phase III Noninferiority Study
 Primary endpoint: OS
 Secondary endpoints: PFS, ORR (RECIST v1.1), clinical benefit, safety
Follow-up for
minimum of 2 yrs
Nephrectomy
(n = 226)
Sunitinib 50 mg QD† 4 wks on/2 wks off
(n = 224)
Confirmed metastatic clear-cell RCC/biopsy;
ECOG PS 0/1;
amenable to nephrectomy
eligible for sunitinib;
brain metastases absent/controlled by treatment;
no prior systemic therapy for RCC
(N = 450) *
Stratified by center, MSKCC risk group (intermediate vs high risk)
*114 patients versus 115 received other lines of therapy in each group, respectively
†Dose reductions/interruptions allowed for managing AEs.
Sunitinib 50 mg QD*
4 wks on/2 wks off
(n = 226)
3-6 wks
Méjean. NEJM. 2018;379:417

No statistically significant differences in OS or PFS Median OS
was 18.4 mos in sunitinib group vs 13.9 mos in nephrectomy

Conclusion
 Sunitinib alone is non inferior to cytoreductive nephrectomy followed
by sunitinib for overall survival, both in intermediate and poor risk
patients with metastatic RCC
 Clinical benefit was also significantly better in the sunitinib alone arm
 Cytoreductive nephrectomy should no longer be considered standard
of care in intermediate and poor risk MSKCC groups of metastatic RCC,
at least when medical treatment is required

Drawbacks of CARMENA
1- Possible patient selection bias
• 43% of the patients had poor-risk disease and the remaining patients
had intermediate-risk disease.
• nephrectomy group had a higher percentage of locally advanced tumors
of stage T3 or T4 than the sunitinib group (70.1% vs. 51.0%)
2- Inconsistent outcomes versus other trials
median overall survival was 18.4 months (95% CI, 14.7 to 23.0) in the
sunitinib-alone group but Other trials report median 21-26 months
sunitinib alone.

3- Significant patient attrition
• Nephrectomy–sunitinib group :
a) 40 patients [17.7%] did not receive sunitinib
b) 16 [7.1%] did not undergo nephrectomy
• Sunitinib-alone group :
a) 11 patients [4.9%] did not receive sunitinib
b) 38 [17.0%] underwent delayed nephrectomy
c) Median of 11mos from randomization?!?

Considerations for Nephrectomy

2- Is there a role of active surveillance in
m. RCC ?????

Prospective, Phase II Observational Study in Patients
With Asymptomatic Metastatic RCC
Initiation of
systemic
treatment
per doctor/
patient
discretion
CT every 3 mos in Yr 1, every 4 mos in Yr 2,
then every 6 mos
 FKSI-DRS (QoL) and HADS (anxiety/depression) assessments
administered at baseline and at every CT scan timepoint
 Peripheral blood for immune cell quantification drawn at
baseline and at every CT scan time point
Rini. Lancet Oncol. 2016;17:1317.
 Patients with clinically evident metastatic
RCC of any histologic subtype (N = 48)
 First documentation (radiographic or
histologic) of metastatic RCC up to 12
months prior to registration on study
 No prior systemic therapy for RCC in the
metastatic or neo/adjuvant setting
 Prior XRT (including for CNS metastases)
and prior nephrectomy/metastasectomy
permitted but not required
 No disease-related symptoms
 Measurable/evaluable disease per
RECIST v1.0

The Argument for Active Surveillance
 done In selected patients (favorable risk) active surveillance to :
‒ Avoids the certain toxicity of systemic therapy
‒ No clearly the benefit of therapy when initiated
 NCCN Guidelines list active surveillance as “useful in certain
circumstances” (2A)
 The selection and outcomes of patients undergoing active surveillance
for mRCC have not been well described

3- How to choose 1st line anti VEGF
in m.RCC ?? Case study

What to do next regarding 1st line setting ?
 1- start sunitinib
 2- start pazobanib
 3- start INF + bevacizumab
 4- start sorafinib
 5- uncertain

800 m.g daily
50 m.g 4wks on + 2 wks off

4- what are options after TKI ??

Dose : 5m.g BID
3m.g / kg every 2 wks

If combined with evrolimus :
18 m.g + evrolimus m.g once
If alone :
24 m.g daily
• Is there a role of nephrectomy in m.Rcc
?? Yes in good PS and limited extra
renal disease
• Are we dare enough to put m.RCC
patient on active surveillance ?? Yes in
favorable risk with no benefit of
starting ttt
• Is there any difference between TKIs in
1st line in m.RCC ? Nooo
• What are 2nd options in refractory or
relapsed m.RCC ?? Many acc .
Avialbility

PD-1 is expressed on activated T cells and when it binds to its ligand PD-L1 on tumor cells leads to T
cell exhaustion.
CTLA-4 competes with CD28 (costimulatory T cell molecule) for B7 ligands (CD80 and CD86 that are
not shown in the figure) and upon activation decreases T cell proliferation as well as activity.
Blockade of CTLA-4 (by anti-CTLA-4) and PD-1 (anti-PD-1) or PD-L1 stimulates effector T cells to
produce antitumor responses

case study
• Female 70 y PS 0 8/2017 underwent nephrectomy with no adj ttt
observation For 1 y ( ccRCC T2N0MO GR 2)
• 8/2018 : App. Of lung nodules but were not much burden by RECIST
criteria
• so kept on active surveillance 1.5 yr
• 2/2020 on routine follow up :
DP lung nodules and hilar with retroperitoneal LND
Biopsy lung nodules : same renal pathology

What are Options for Subsequent Management?
‒ VEGFR TKI monotherapy
‒ Combination immunotherapy (CTLA-4/PD-1)
‒ Combination VEGFR/PD-1 therapy

Main Conclusions
 Treatment with pembrolizumab plus axitinib resulted in significantly
longer overall survival and progression-free survival and a significantly
higher objective response rate than sunitinib alone”
 Benefit was observed across all IMDC groups
 The incidence of grade 3/4 adverse events was similar (67% with
pembrolizumab + axitinib vs 62% with sunitinib)
 This study changed practice patterns in RCC

What is “big-picture” benefit achieved in patients
with IMDC intermediate-/poor-risk RCC receiving
these new standard regimens?

PD-1–Based Combinations in IMDC Intermediate-/
Poor-Risk Patients how to choose
 Short-term efficacy:
‒ TTR and PFS were superior to
sunitinib for both regimens
‒ The rate of PD as best response
was near double for Nivo + Ipi vs
Axitinib + Pembro
 Long-term efficacy:
‒ Unequivocal long-term benefit for
Nivo + Ipi
‒ Do not yet have data for long-term
benefit with Axitinib + Pembro
 Toxicity:
‒ Worse chronicity for axitinib +
Pembro; even in patients without
irAES, there is ongoing QoL impact
from axitinib
‒ Greater need for toxicity-related
treatment discontinuation, and for
immunosuppression, with Nivo +
Ipi

MK-6482 in Advanced Clear-Cell RCC:
 Among patients with clear-cell RCC, at least one half possess mutations
in the tumor suppressor gene VHL encoding pVHL[1,2]
 pVHL deficiency leads to constitutive activation of transcription factor
HIF-2α, a renal oncoprotein[1,2]
 MK-6482: investigational, selective, small-molecule inhibitor of HIF-2α[3]
 Current analysis evaluated safety and efficacy of MK-6482 in patients
with heavily pretreated, advanced clear-cell RCC enrolled on dose-
expansion cohort of ongoing phase I/II trial[4]

Conclusions
 In this analysis of the dose-expansion cohort of an ongoing phase I/II trial in patients with
heavily pretreated advanced clear-cell RCC, MK-6482 was associated with on-target
toxicities of anemia and hypoxia
‒ Any grade/grade 3: anemia, 75%/26%; hypoxia, 26%/15%
 Clinical activity was observed across IDMC risk categories in this study population
‒ ORR of 24% (all PRs), with responses lasting ≥ 6 mos in 81% of patients
‒ Median PFS: 11 mos; 12-mo PFS rate: 49%
 Recruitment ongoing for phase III trial comparing MK-6482 vs everolimus in patients with
advanced RCC after progression on anti–PD-1/PD-L1 and anti-VEGF agents (NCT04195750)

We also determined chromosome copy-number aberrations,
methylation status, and gene mutations in von Hippel-Lindau
and PBRM1. Molecular data were analyzed in relation with
response rate (RR), progression-free survival (PFS), and overall
survival (OS).
ccrcc1/ccrcc4 tumors had a lower RR (P = 0.005) and a shorter
PFS and OS than ccrcc2/ccrcc3 tumors (P = 0.001 and 0.0003,
respectively).

crcc1/ccrcc4 tumors were characterized by a stem-cell polycomb signature and
CpG hypermethylation, whereas ccrcc3 tumors, sensitive to sunitinib, did not
exhibit cellular response to hypoxia.
Moreover, ccrcc4 tumors exhibited sarcomatoid differentiation with a strong
inflammatory, Th1-oriented but suppressive immune microenvironment, with high
expression of PDCD1 (PD-1) and its ligands

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

General Principles for Managing irAEs
 Consult promptly with relevant specialists for affected organ systems (eg, GI, dermatology)
 Management generally based on severity of symptoms
‒ Mild (grade 1): supportive care, consider holding ICI
‒ Moderate (grade 2): hold ICI, re-dose if AE improves, consider low-dose steroids (prednisone
0.5-1 mg/kg/day)
‒ Severe (grade 3): discontinue ICI, monitor closely (likely inpatient), start high-dose steroids
(prednisone 1-2 mg/kg/day) with a slow taper (≥ 1 mo)  If not improving in 1-3 days, increase
immunosuppression
 For steroid-refractory AEs, consider adding infliximab, mycophenolate mofetil, etc
‒ Diarrhea  consider adding infliximab or vedolizumab
‒ Hepatitis  consider adding mycophenolate mofetil
Brahmer. JCO. 2018;36:1714.
‒ Pneumonitis  consider adding
infliximab, mycophenolate
mofetil, or IVIG
