Figure 2From: Quantification of the response of circulating epithelial cells to neodadjuvant treatment for breast cancer: a new tool for therapy monitoringChanges in circulating tumour cell numbers. (a) Fourteen typical courses of changes in cell numbers in breast cancer patients monitored during neoadjuvant (primary) therapy. (b) Comparison of the response of circulating tumour cells during the first three (or four) therapy cycles versus tumour reduction in the therapy regimen without herceptin (thick lines) and the regimen including herceptin (thin line).Back to article page
