Rational Approaches to Treatment Duration with Immunotherapy in Metastatic Renal Cell Carcinoma.
Immune checkpoint inhibitors (ICIs) have revolutionized the treatment paradigm for metastatic renal cell carcinoma. The appropriate duration for ICI treatment is not clear, however. Analyses of landmark trials reveal that some patients exhibit sustained durable responses to ICIs even after treatment discontinuation, resulting in prolonged treatment-free intervals that can mitigate potential toxicities and the considerable financial burden associated with treatment. Adaptive approaches with PD1 monotherapy and combination immunotherapy tailored to tumor response are ongoing. More efforts will be needed to clarify the ideal ICI dosing regimen to maximize oncological benefit while minimizing treatment-related adverse effects and costs. PATIENT SUMMARY: We reviewed considerations surrounding treatment strategies when using immunotherapy to treat patients with kidney cancer. It is clear that some patients can experience prolonged cancer control when discontinuing immunotherapy. However, individualized approaches will be necessary to strike a balance between optimizing patient outcomes and reducing unnecessary side effects and cost.
