Dear colleagues,
The landscape of kidney cancer treatment is in a state of rapid and thrilling evolution. As editors, we are privileged to witness and disseminate the groundbreaking research that is reshaping how we approach renal cell carcinoma (RCC). The past year has been particularly transformative, punctuated by pivotal data presented at major symposia and a continuous influx of innovative therapeutic strategies.
As we reflect on the recent American Society of Clinical Oncology (ASCO) 2025 Annual Symposium, a clear narrative emerges: the era of combination therapy is not just established, but is being refined. What was once an experimental approach has become the bedrock of first-line treatment for advanced RCC. The latest data suggest a shift toward more personalized—and even finite—treatment durations.
ASCO 2025: Key Abstracts and Enduring Data
The ASCO 2025 Genitourinary Cancers Symposium was a landmark event for the kidney cancer community, offering validation of established strategies while also illuminating the future. A prominent theme was the continued maturity of long-term follow-up data for combination regimens.
- Long-term Follow-up of Immune Checkpoint Inhibitors (ICIs): Nine-year follow-up data from the CheckMate-214 trial (Motzer et al.) reaffirmed the durable benefit of nivolumab plus ipilimumab. A meaningful portion of intermediate- and poor-risk RCC patients remained alive and progression-free at nine years—an extraordinary milestone for metastatic disease. These findings reshape expectations for survival and long-term counseling.
- Refining Triple-Drug Regimens: The COSMIC-313 trial, investigating cabozantinib + nivolumab + ipilimumab, demonstrated significant improvement in progression-free survival versus nivolumab + ipilimumab alone. Although OS data remain immature, the robust PFS benefit and manageable safety profile position this triplet as a potent option—particularly for patients needing rapid disease control.
- The Dawn of Treatment De-escalation: One of the most compelling ASCO GU 2025 findings involved treatment de-escalation. A study of nivolumab + axitinib showed that metastatic RCC patients who achieved strong responses could safely discontinue or pause therapy after two years. Most who stopped remained progression-free for an additional two years without retreatment. This challenges the paradigm of indefinite therapy, highlighting opportunities to reduce toxicity, improve quality of life, and decrease cost.
Exploring New Avenues: Emerging Therapies and Biomarkers
- HIF-2α Inhibitors: The HIF-2α inhibitor class, led by belzutifan, continues expanding. Following approval for VHL-associated RCC, belzutifan is now approved for previously treated advanced clear-cell RCC. Data from ARC-20 and similar studies reinforce that targeting the HIF-VHL pathway remains one of the most effective molecular strategies in RCC.
- Vaccines and Cellular Therapies: Personalized neoantigen vaccines for high-risk, resected RCC are showing promise. Early data demonstrate strong, durable immune responses with prolonged disease-free intervals. Meanwhile, allogeneic CAR-T and NK-cell therapies (e.g., ALLO-316) suggest a future where cellular immunotherapy becomes viable for solid tumors.
- The Search for Biomarkers: Biomarker-driven treatment selection is advancing rapidly. A new CheckMate-214 analysis indicated that higher baseline Kidney Injury Molecule-1 (KIM-1) levels correlate with worse prognosis, and reductions in KIM-1 align with improved PFS. Such biomarkers may soon guide treatment selection and monitoring.
Upcoming Conference: IKCS 2025 North America
Momentum continues with the upcoming International Kidney Cancer Symposium (IKCS) 2025: North America, taking place in Denver, Colorado from November 13–15, 2025. IKCS is renowned for uniting oncologists, surgeons, radiologists, pathologists, and advocates in a multidisciplinary forum.
This year’s program will feature advances in surgical techniques, ablative technologies, systemic therapies, and translational science. Key discussion areas will include optimal sequencing, toxicity management in combination regimens, and the evolving role of biomarkers in everyday practice.
In This Issue: Diagnostic Innovation
This issue highlights significant progress in non-invasive diagnostics. The featured papers "Urine C-reactive protein content and non-invasive molecular grading of renal cell carcinoma" and "Practice-Ready Molecular Imaging in Renal Cell Carcinoma" showcase emerging tools that enhance early diagnosis, grading accuracy, and precision imaging—bringing us closer to fully personalized RCC care.
Conclusion
The collective data from the past year reaffirm that we are entering a new era in kidney cancer care. Durable responses, the possibility of finite treatment duration, and the rise of novel therapies and biomarkers offer unprecedented hope. While challenges remain, each new study brings us closer to a future where kidney cancer becomes a manageable chronic condition for many patients.
We look forward to sharing these advances and to the continued collaboration that drives progress.
