Does Tumour Contrast Retention on CT Immediately Post Chemoembolization Predict Tumour Metabolic Response on FDG-PET in Patients with Hepatic Metastases from Colorectal Cancer?

Table 2

Association of metabolic response with response match type. Response type and match were significantly associated with metabolic response.

Variables	Metabolic response ()			value
	Complete (, %)	Partial (, %)	Progression/no response (, %)
Match type
Type 1	10 (100)	12 (92.3)	1 (6.7)	N/A
Type 2	0	1 (7.7)	1 (6.7)
Type 3	0	0	13 (86.6)
Match type
Type 1	10 (100)	12 (92.3)	1 (6.7)	<0.0001
Types 2 & 3	0	1 (7.7)	14 (93.3)

In complete response, partial response and progression/no response, percentages of type 1 match type were 100, 92.3, and 6.7, respectively.
