Summary

The incidence of brain metastasis of Her2-negative breast cancer is high, which seriously affects the prognosis of patients.The treatment of brain metastasis of Her2-negative breast cancer is still tricky. The local efficacy of head radiotherapy for breast cancer brain metastases is remarkable, and systemic tumor progression in patients with brain metastases is the main reason for treatment failure. Sacituzumab Govitecan is the only Trop-2 antibody-coupled drug (ADC) approved for the treatment of unresectable locally advanced or metastatic Her2-negative breast cancer. However, the objective remission rate of Sacituzumab Govitecan for intracranial metastatic lesions has not been satisfactory. This study is an open, uncontrolled phase II clinical study to observe the efficacy and safety of Sacituzumab Govitecan combined with intracranial radiotherapy in the treatment of patients with brain metastases from Her2-negative breast cancer, in order to find a more effective treatment method.

Conditions

  • Brain Metastasis

Interventions

DRUG

Sacituzumab Govitecan

Patients were treated with Sacituzumab Govitecan 10 mg/kg in 21-day treatment cycles with intravenous infusions on days 1 and 8 and continued until disease progression or unacceptable toxicity.

RADIATION

Radiotherapy

Radiotherapy was administered after the second infusion of Sacituzumab Govitecan, on day 9 after the start of this regimen. The radiotherapy regimen was: brain metastases at a dose of 60 Gy/20 doses. For lesions located adjacent to the brainstem and optic nerve, 54 Gy/20 doses were given. For patients with ≥5 lesions, whole-brain radiotherapy at 40 Gy/20 doses was synchronized with radiotherapy to localized brain metastases.
