    The integration of TKIs in immunotherapy is transforming treatment protocols, particularly in various cancer types:

    • Non-Small Cell Lung Cancer (NSCLC): TKIs addressing EGFR mutations can improve immune responses when combined with PD-1 inhibitors.
    • Renal Cell Carcinoma: The use of TKIs like sunitinib alongside immunotherapy has shown synergistic benefits, leading to improved survival rates.

    The practical applications of how TKIs enhance immunotherapy effectiveness showcase the evolving nature of cancer treatment and its focus on patient-centric therapies.

    Current Challenges

    Despite the promising potential, several challenges persist in the study and application of TKIs with immunotherapy:

    • Variability in patient responses due to genetic differences
    • Potential adverse effects associated with combination therapies
    • Regulatory hurdles in approving combination treatments

    Addressing these challenges is critical to realizing the full benefits of TKIs within the context of immunotherapy.
