Table 4 Sensibility, specificity, positive predictive value (PPV) and negative predictive value (NPV) of immunohistochemistry using SP3 and CB11 antibodies, having chromogenic in situ hybridisation (CISH) as gold standard.

	Sensibility	Specificity	PPV	NPV
CB11	0.52	0.98	0.92	0.93
SP3	0.52	0.99	0.96	0.84
