Clinical Scorecard: Comparison of Stereotactic Radiotherapy and Hippocampal Avoidance Whole-Brain Radiotherapy with Immune Checkpoint Inhibitors in Non-Small Cell Lung Cancer Patients with Multiple Brain Metastases: A Multi-Center Retrospective Analysis

At a Glance

CategoryDetail
ConditionNon-Small Cell Lung Cancer with Multiple Brain Metastases
Key MechanismsStereotactic Radiotherapy (SRT) and Hippocampal Avoidance Whole-Brain Radiotherapy (HA-WBRT) combined with Immune Checkpoint Inhibitors (ICIs)
Target PopulationPatients with Non-Small Cell Lung Cancer and more than four brain metastases
Care SettingRetrospective analysis in multi-center clinical practice

Key Highlights

  • SRT+ICIs showed significantly longer median overall survival (21.4 months) compared to HA-WBRT+ICIs (15.5 months; P<0.001).
  • SRT+ICIs also demonstrated improved median intracranial progression-free survival (10.5 months vs. 8.1 months; P<0.001).
  • No grade > 3 adverse events were reported in either treatment cohort.

Guideline-Based Recommendations

Diagnosis

  • Confirm diagnosis of Non-Small Cell Lung Cancer with MRI showing multiple brain metastases (>4 lesions).

Management

  • Consider SRT+ICIs as a treatment option for improved overall survival and intracranial progression-free survival.

Monitoring & Follow-up

  • Monitor overall survival and intracranial progression-free survival as primary endpoints.

Risks

  • Assess for potential adverse events, although no grade > 3 AEs were found in this study.

Patient & Prescribing Data

NSCLC patients with multiple brain metastases treated with RT and ICIs.

SRT combined with ICIs may enhance treatment efficacy without increasing adverse events.

Clinical Best Practices

  • Utilize propensity score matching to balance baseline characteristics in treatment comparisons.
  • Incorporate multidisciplinary review for target volume delineation in SRT planning.
