Table 3. Comparing observed survival (Kaplan Meier) versus predicted survival (Model FP) for treatment failure at 3 and 5 years.

	% Observed survival 3 years (95% CI)	% Predicted survival 3 years	% Observed survival 5 years (95% CI)	% Predicted survival 5 years
CTC and mM negative	92% (77%–97%)	92%	87% (67%–95%)	88%
CTC negative mM positive	71% (43%–87%)	74%	58% (32%–76%)	62%
CTC positive	6% (0.5%–24%)	11%	6% (0.5%–24%)	4%

CTC = circulating tumour cell; mM = micro-metastasis
