入选标准

  • 1.Male or female, 18 years of age or older
  • 2.Patients with histologically proven ER-positive, HER2-negative advanced breast cancer receiving an AI in combination with a CDK 4/6 inhibitor. Biopsy of metastatic disease if technically feasible but not mandatory.
  • 3.Patients must have evidence of extracranial metastatic disease with or without intracranial metastases.
  • 4.Radiological evidence of stable or responding disease to an AI in combination with a CDK 4/6 inhibitor for a period of at least 6 months prior to study entry. (Patient must have ongoing stability/response in at least one lesion at the time of registration).
  • 5.Evidence of new or existing OPD in 1-5 lesions. With reference to RECIST 1.132 and or PERCIST 1.033, OPD is defined as follow:
  • a.Using CT for intracranial or extracranial OPD:
  • i.greater than 5 mm increase in the diameter of an existing lesion OR
  • ii.more than 20% increase in the diameter of an existing lesion on 2 consecutive imaging studies at least 2 months apart OR
  • iii.The appearance of one or more new soft tissue lesions, measuring more than 5 mm.
  • b.Using Positron Emission Tomography for extracranial OPD:
  • i.greater than 30% increase in 18F-FDG SUV peak, with more than 0.8 SUV units increase in tumour SUV from the baseline scan in pattern typical of tumour and not of infection/treatment effect OR
  • ii.New 18F-FDG avid lesions typical of cancer (including new bone lesion) and not related to treatment effect and/or infection.
  • 6.For patients with liver or lung metastases, maximum of 3 oligoprogressive lesions in single organ.
  • 7.All OPD must be amenable to SRT.
  • a.Patients with risk of bone fracture are not candidate for SRT
  • 8.For patients with intracranial metastases, SRT is the preferred treatment option, however, if clinical assessment indicated that upfront surgery is better, then post-operative SRT to the surgical cavity is recommended.
  • 9.ECOG performance status 0-2.
  • 10.Life expectancy of greater than 6 months.
  • 11.Provision of written informed consent.
  • 12.Clinician and participant are willing to continue current line of therapy.

排除标准

  • 1.Pregnancy or lactation at the time of study entry.
  • 2.Evidence of more than one clone of metastatic disease e.g. ER-positive and ER-negative and or HER2-positive disease. (To exclude those with some ER-positive and some TNBC or HER2-positive disease).
  • 3.Evidence of Leptomeningeal disease.
  • 4.Evidence of Malignant cord compression.
  • 5.Previous chemotherapy for metastatic disease (chemo for primary breast cancer is allowed).
  • 6.Contraindication to radiotherapy.
  • 7.Previous radiotherapy in which the treated area planned to receive treatment is greater or equal to EQD2 40 Gy.
  • 8.Any condition deeming the patient unsuitable to comply with the study.
