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

A durable response to trastuzumab in heavily pretreated metastatic breast cancer

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

Biomarkers: Initial tumor ER-positive and PR-positive. Metastatic liver biopsy ER-negative and PR-negative with HER2 IHC 1+ and nonamplified. Later biopsy ER and PR weakly positive at 5%–10%, HER2 IHC 1+ and nonamplified, and ERBB3 p. with evidence of HER2/HER3 pathway activation.

Metastatic Site: lungs; hilar and mediastinal lymph nodes; liver; bone

She had ongoing benefit for more than 10 months on trastuzumab and capecitabine, with improved symptoms, lower tumor markers, and a confirmed partial response.

Lobular breast cancer later spread to the stomach, bone, neck and mediastinum

Patient Info: Anonymized, Female, 70+ | Stage IV

Biomarkers: ER-positive; PR-positive; HER2-negative

Metastatic Site: stomach|bone|neck|mediastinum

Stage IV Breast Cancer: Kirby's Patient Story

Patient Info: Kirby Lewis, Male | Stage IV

Biomarkers: ER-positive, PR-positive, HER2-negative

A patient, who was diagnosed with Stage I Invasive Lobular CarcinomaBreast Cancer

Early breast cancer followed 19 years later by a radiation-related breast sarcoma

Patient Info: Anonymized, Female, 70+ | Stage I

Biomarkers: Strongly ER-positive; strongly PR-positive.

The stage IA breast carcinoma remained disease-free for 19 years; a later right-breast mass was a separate radiation-induced sarcoma rather than recurrent carcinoma.
