Clinical Scorecard: Assessing the Effectiveness and Safety of Initial Immunotherapy for Metastatic Triple-Negative Breast Cancer: A Systematic Review and Bayesian Network Meta-Analysis of Randomized Controlled Trials Considering PD-L1 Expression Levels

At a Glance

CategoryDetail
Condition
Key MechanismsImmune checkpoint inhibitors (ICIs) such as pembrolizumab and toripalimab combined with chemotherapy enhance anti-tumor immune response by blocking PD-1/PD-L1 pathway.
Target Population
Care Setting

Key Highlights

  • ICIs combined with chemotherapy significantly improve overall survival (OS) and progression-free survival (PFS) compared to chemotherapy alone. (Clarify statistical significance of AE≥3 findings.)

Guideline-Based Recommendations

Diagnosis

    Management

      Monitoring & Follow-up

      • Monitor overall survival, progression-free survival, and adverse events during treatment, including specific events like neutropenia and infusion reactions.

      Risks

        Patient & Prescribing Data

        Patients diagnosed with metastatic triple-negative breast cancer, particularly those with PD-L1 expression levels ≥1%.

        Combination therapies involving ICIs and chemotherapy are recommended for improved survival outcomes.

        Clinical Best Practices

        • Implement a multidisciplinary approach for managing treatment-related adverse events, including input from oncology, nursing, and supportive care teams.
