Highlights from RENALC24:

“Highlights from RENALC24: RCC Management Insights for 2025 Looking ahead: RCC management in 2025

Moderator: Saeed Dabestani

– Pre-op imaging: Transitioning from 2D to advanced 3D imaging for precise surgical planning. Key focus on tumor depth, size, and vessel orientation.

– SBRT advancements: New MRI LINAC studies emphasize safety and efficacy in non-surgical RCC patients.

– Updated DFS data: Pembrolizumab shows 35% recurrence despite use, but 57% cured by surgery alone.

– Leibovich 2003 Validation: Improved risk discrimination in RCC survival metrics.

– Neoadjuvant RCC trials: 16 ongoing! Exploring PD-1/PD-L1 combos & innovative endpoints for better pathologic responses.

– NESCIo study design: 3-arms comparing nivolumab, ipilimumab, and relatlimab for high-risk RCC. Exciting phase II outcomes ahead!

– Atezolizumab DFS advantage: Particularly effective in KIM-1^high subgroup.

– Future view by urologists: Tailored approaches with focus on combined immunotherapy & targeted TKIs for advanced RCC.”

To operate or not? Axel Bex FOR YES:

Debate: To operate or not? Deferred cytoreductive nephrectomy in the ICI era=

Axel Bex FOR YES and Pignot Géraldine FOR NO

FOR YES:

Key Points:

– Real-world data shows 17% underwent deferred CN with NIVO+IPI.
– Median OS: 31.9 months (intermediate risk: 49.8m, poor risk: 15.2m).
– Ongoing trials (NORDIC-SUN, PROBE) will clarify the role of deferred CN.”

To operate or not? Pignot Géraldine FOR NO:

“Debate: To operate or not? Deferred cytoreductive nephrectomy in the ICI era

Axel Bex FOR YES and Pignot Géraldine FOR NO

FOR NO:

Delayed CN may benefit patients with complete response to immunotherapy but shows limited value for partial responders.  Andreas is not ideal for delayed CN.

Surgical complexity is influenced by primary tumor downsizing (>20% = 76% complexity). Adhesions/fibrosis complicate 71% of surgeries.

New strategies & trials (NAMECAR, SPICI-GETUG R05) explore treatment pauses and desescalation for select responders.

Personalized approaches to CN decision-making are evolving!”

Treatment options for patients with metastatic papillary RCC:

“Treatment options for patients with metastatic papillary RCC

Key insights on metastatic papillary RCC from RENALC24:

– Molecular insights: Papillary RCC arises through VEGF, MET, and mTOR pathways. Type 1 (MET mutations) vs Type 2 (FH, TFE3 alterations).

– Cabozantinib improves PFS (9 vs 5.6m) & ORR in unselected cohorts vs sunitinib (p=0.019).

–  VEGF-targeted therapies & combos like Lenvatinib+Eve/Cabo show promise in response rates.

– Promising IO-TKI: LenPem excels in pRCC; combos shaping new standards of care.

– Bevacizumab+Erlotinib: Highly effective in HLRCC (ORR 72%), less so in sporadic pRCC (35%).”

First-line treatment for advanced clear-cell RCC:

“Selecting first-line treatment for advanced clear-cell RCC

Highlights from RENALC24: Translating Data to Practice!

1. Local therapy matters in mRCC

– Surgery or radiotherapy improves survival: 106 vs 59 months.
– Systemic therapy received by 93% of patients.
– Key takeaway: Local interventions + systemic treatment = better outcomes.

2. Timing in mRCC treatment

– Active surveillance (AS): Median time = 14.9 months. Median OS on AS = 44.5 months.
– Benefits of late treatment: Delayed resistance = greater benefit from novel therapies!

3. Current Standard of Care

– Median OS > 50 months. ORR up to 70%. PFS up to 24 months.
– Immunotherapy (ICI) combos remain pivotal!

4. Sarcomatoid RCC patients

– Best responders to ICI-ICI (Nivo+Ipi):
– ORR: 60.8%, CR: 23% (all sRCC).
– ORR: 69.4%, CR: 25% (PD-L1+ sRCC).

5. Brain & pancreatic mets impact treatment

–  ICI-TKI > ICI or TKI alone for brain metastases.
– Pancreatic mets benefit more from ICI+TKI.

6. Choosing the right combo  

– Favorable risk: VEGFR inhibition (Axi+Pem).
–  Aggressive disease: Resistance-TKIs (Cabo+Nivo or Len+Pem).”

Case-based approach by Petros Grivas:

“Translating New Data into Clinical Practice: Case discussions highlight the role of evidence in decision-making! Key takeaways from RenalC24:

Mirrors of Medicine – case-based approach by Petros Grivas.

Panel ratings: Using the Delphi method to evaluate clinical cases with focus on appropriateness.

Josef’s case: Choices in metastatic ccRCC after ICI-TKI therapy—balancing risks & benefits.

Treatment pathways include: VEGFR-TKIs, dual ICI regimens, and combination therapies.

Clinical decision-making relies on panel recommendations vs peer opinions—bringing consensus to the forefront!”

Risk assessment of post-nephrectomy patients:

“Risk assessment of post-nephrectomy patients
Presenter: Philippe Barthélémy

KN564: The ONLY positive trial for adjuvant RCC with significant OS and DFS benefits in clear-cell histology.

Risk Stratification: TNM stage and ISUP grade crucial for identifying high-risk patients eligible for adjuvant therapy.

Prediction Models: Current tools (UISS, SSIGN) lack precision; real-world data highlights the need for personalized risk assessment.

UroPredict: Machine learning-based models show potential in refining recurrence risk prediction and patient selection.

Next Steps: Development of predictive biomarkers for efficacy and toxicity to achieve individualized treatments.”

Saeed Dabestani on the history of Cytoreductive nephrectomy:

“Cytoreductive nephrectomy: The history

Presenter: Saeed Dabestani

Congress: RENALC24

2001 EORTC 30947: First RCT showed survival benefit of cytoreductive nephrectomy (CN) + IFN-α over IFN-α alone.

2004 Meta-analysis: Combined SWOG and EORTC data confirmed OS benefits of CN, increasing its use in mRCC management.

Targeted therapy era: Trials like CARMENA and SURTIME redefined the role of CN alongside systemic therapies like Sunitinib.

Key insights: Deferred CN (SURTIME) offers survival benefit in selected patients, highlighting the importance of patient selection.

Future directions: Integration with immune checkpoint inhibitors requires updated strategies for CN use.”

Weighing the pros and cons of adjuvant therapy:

“Debate: Weighing the pros and cons of adjuvant therapy

Speakers: Saeed Dabestani

KN564: Clear benefits in DFS and OS for high-risk RCC patients with Pembrolizumab.

Adverse events: 36.5% immune-related AEs and 21.1% discontinuation rates highlight toxicity concerns.

Risk stratification: Precise tools are needed to avoid overtreatment while maximizing outcomes.

Key message: Inform patients about risks and benefits to empower shared decision-making.

Future direction: Integrating biomarkers and AI-driven prediction models for individualized care.”
