Genetic Basis and Surgical Implications

  • Historical approach vs. current understanding
  • Kidney cancer as multiple diseases with different genetics, clinical courses, and responses to therapies
  • Importance of genetics for tailored management:
    • Active surveillance vs. surgery
    • Type of surgery: robotic vs. open, enucleation vs. wide margins
    • Treatment options post-surgery

Case Studies and Surgical Approaches

  1. Von Hippel Lindau (VHL) Disease
  • VHL gene mutation leading to clear cell renal carcinoma (ccRCC)
  • Historical surgical management: active surveillance until tumors reach 3 cm; then partial nephrectomy
  • Enucleation techniques: nucleation without wide margins
  • Case: Patient with multiple renal tumors, successfully managed with partial nephrectomy
  1. Sporadic Non-Inherited ccRCC
  • Case: Biopsy showed clear cell RCC with a VHL mutation
  • Considerations for nucleation vs. wide excision
  1. Advanced and Metastatic ccRCC
  • Pathway understanding: VHL protein's interaction with HIF
  • FDA approval of 9 drugs targeting this pathway
  • HIF-2 inhibitors showing promise
  1. Hereditary Papillary Renal Carcinoma (HPRC)
  • MET gene mutation
  • Active surveillance until tumors reach 3 cm
  • Case: Managing multiple multifocal tumors
  1. FH Gene-Related Kidney Cancers
  • Fumarate Hydratase (FH) deficiency
  • Importance of wide resection margins
  • Case: Small tumors with invasion, aggressive surgical approach

Precision Surgery in RCC

  • Predictors for open vs. robotic, enucleation vs. wide excision, clamping vs. non-clamping
  • Managing multifocal, complex cases, and balancing functional outcomes
  • Importance of continuous adaptation based on individual patient and tumor characteristics

Cytoreductive Nephrectomy

  • Indications and outcomes
  • Considerations for upfront vs. systemic therapy
  • Importance of clinical trials and evolving guidelines

Recent Advances and Immunotherapy

  • Contribution of Dr. David McDermott
  • Targeted immunotherapy combining PD-1 inhibitors with other therapies
  • Biomarkers and durable responses
  • Evolving role of immune therapy in RCC management

Future Directions in Genetic and Targeted Treatments

  • Insights from Dr. Rahm Cervasin
  • Understanding molecular subtypes for personalized therapy
  • Impact of systemic therapies on historically difficult-to-treat forms like HLRCC
  • Promising results from novel agents

Conclusion

  • Integration of genetic understanding with clinical management advances
  • Importance of multi-disciplinary approaches in RCC management
  • Continuous innovation in treatment strategies

Key Takeaways

  • Personalized Medicine: Genetic insights transforming RCC management
  • Surgical Techniques: Adapt and personalize based on genetic and clinical factors
  • Immunotherapy: Significant progress in durable, effective treatment options
  • Future Research: Continued innovation in targeted and systemic treatments
