A patient, who was diagnosed with Stage IV Invasive Ductal CarcinomaBreast Cancer

Breast cancer spread into a separate kidney cancer

Patient Info: Anonymized, Female, 60s | Stage IV

Metastatic breast cancer with receptor evolution: sequential endocrine, immunotherapy, CDK4/6, and antibody-drug conjugate treatment

Patient Info: Anonymized, Female, 50s | Stage IV

Biomarkers: Markers changed over time: initial tumor ER-positive/HER2-negative; local recurrence triple-negative/HER2-low; pleural fluid ER-negative.

Metastatic Site: mediastinal lymph nodes, pleura; pulmonary nodules…

More than 7 years after diagnosis, she remained on sequential systemic therapy for metastatic breast cancer, with at least a partial response 3 months after starting sacituzumab govitecan for presumed triple-negative pleural disease.

HR-positive HER2-negative metastatic breast cancer: bone metastases managed with sequential endocrine therapy

Patient Info: Anonymized, Female, 50s | Stage IV

Biomarkers: ER 90%+, PR 80%+, HER2-. CA 15-3 was tracked during treatment.

Metastatic Site: skull base; spine; sternum; ribs; left iliac bone;…

Metastatic HR-positive, HER2-negative breast cancer remained under active management; after earlier progression, palbociclib plus fulvestrant and zoledronic acid produced stable/remission findings on PET/CT at 3 months and again 1 year later, with continued 3-month follow-up recommended.
