Introduction: Performing surgery for renal cell carcinoma (RCC) in patients with horseshoe kidneys presents unique anatomic challenges. The complexities of clinical decision-making and technical challenges are further compounded by the presence of both IVC tumor thrombus extension and metastatic disease.

Case presentation: We encountered the unique case of a 66-year-old woman with a horseshoe kidney who presented with a 14cm mass in her right kidney with level II tumor thrombus extension into the IVC, retroperitoneal lymphadenopathy, and pulmonary nodules that were biopsy-proven to be consistent with metastatic clear cell RCC (cT3aN1M1). She was treated with combination immune checkpoint inhibition (ICI) and targeted therapy upfront. Given her durable response to systemic therapy, we elected to perform a consolidative cytoreductive nephrectomy for residual ypT3aN0 disease, and she has since remained disease-free radiographically. Using step-by-step illustrative photographs obtained intraoperatively, we detail our surgical approach and highlight technical pearls to manage similar cases of advanced RCC arising from horseshoe kidneys.

Conclusion: We present a complex case of metastatic RCC with IVC tumor thrombus arising from a horseshoe kidney. We share our clinical and technical approach to overcoming the medical and surgical challenges inherent to her case. The optimal role and timing of cytoreductive nephrectomy relative to ICI administration continue to evolve based on both tumor- and patient-related factors. Indeed, we favor a multidisciplinary approach to optimize patient outcomes.

The 2024 American Society of Clinical Oncology (GU ASCO 2024) Genitourinary Cancers Symposium brought together leading cancer specialists from around the world to discuss the latest breakthroughs in treating genitourinary cancers, especially kidney cancer. The focus was on immunotherapy and combination treatments, offering promising new options for patients with advanced and high-risk tumors. The symposium also highlighted advancements in patient care, including a new tool to assess quality of life in people with metastatic kidney cancer.

This report highlights key research from the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting, with a focus on clear cell renal cell carcinoma (ccRCC) and non-clear cell RCC (nccRCC) across clinical trials and translational studies. Essential updates in the metastatic ccRCC clinical space encompass results from the CONTACT-03 study, which evaluated an immunotherapy containing regimen for patients who progressed on an initial immunotherapy containing regimen, alongside updated results from the KEYNOTE-426 and CLEAR trials. In the metastatic nccRCC domain, we review clinical trials of combination immunotherapies and tyrosine kinase inhibitors (TKIs). Additionally, we highlight exciting early-phase studies exploring novel targets in RCC and engineered T-cell methodologies. Finally, we summarize notable efforts in translational research, emphasizing biomarker investigations to determine predictors of immunotherapy response, the application of molecular classifiers in RCC, and the relationship between the microbiome and RCC. There were many important RCC related abstracts presented at this year's ASCO conference, attesting to the continued momentum of research in the field. All conference materials, including abstracts and presentations, can be accessed online through the conference website.
