Care SettingRetrospective analysis conducted at university hospitals in Dresden and Leipzig.

Key Highlights

  • The study analyzed 244 cases from two centers over an 8-year period, highlighting the need for larger cohorts.

Guideline-Based Recommendations

Diagnosis

    Management

    • Avoid using Ki67 to guide therapeutic decisions due to its lack of predictive value.

    Monitoring & Follow-up

      Risks

        Patient & Prescribing Data

        Women diagnosed with early HER2-positive breast cancer.

        Focus on established predictive factors rather than Ki67 scores.

        Clinical Best Practices

        • Follow the International Ki67 in Breast Cancer Working Group recommendations for Ki67 evaluation.
