Change in vimentin- and Ki67-expressing CTC after initiation of treatment a) Bar chart assessing proportion of vimentin-positive CTC expression, compared to total CTC expression, at baseline and after treatment start b) Bar chart assessing proportion of Ki67-positive CTC expression, compared to total CTC expression, at baseline and after treatment start. ‘Post-treatment’ samples were taken at cycles 2-3 following initiation of treatment. Mann-Whitney test; Bar charts show mean +/- standard deviation, p=<0.05
