Case 1 (Ms Litsas)
A 64-year-old woman was diagnosed in
2003 with an ER-negative, HER2-positive,
node-positive invasive ductal carcinoma
(IDC) and received adjuvant
chemotherapy. In 2006, metastases were
diagnosed and since then the patient has
received a series of regimens, including
anti-HER2 agents and chemotherapy,
both on and off protocol.

Case 2 (Ms Hopkins)
A 58-year-old woman was diagnosed in
1992 with an ER-positive, HER2-negative,
node-positive IDC and received CMF
followed by five years of adjuvant
tamoxifen. In 2001 metastases were
diagnosed and the patient received
several endocrine agents in sequence
followed by a sequence of single agents
alone or with bevacizumab.
