Diagnosis and guidance of treatment of breast cancer cutaneous metastases by multiple needle biopsy: A case report

摘要

BACKGROUND Breast cancer patients have a high skin metastasis rate.However,reports on treatment of cutaneous metastases of breast cancer are scarce.CASE SUMMARY We report the treatment process for one breast cancer case with bone,lung,and skin metastases.The patient was a 43-year-old woman with advanced breast cancer and skin metastasis.She underwent pathological diagnosis by needle biopsy to guide the treatment.When the disease progressed,a new pathological diagnosis was determined by needle biopsy to guide the treatment.The patient received chemotherapy,endocrine therapy,and photodynamic dynamic therapy,followed by sonodynamic therapy.CONCLUSION Repeated puncture should be performed for advanced breast cancer with skin metastasis,in order to obtain the pathology and directly determine diagnosis when the disease progresses.The treatment should focus on controlling the systemic metastasis,rather than the local disease.
