Table 3. Qualitative and quantitative summary measures to classify disease burden as ER+ or ER- by FES, with response.

	N (%)	Response summary
Average SUVmean (dynamic) > 1.5	13 (69 %)	4 PR
AND no qualitatively negative sites on FES PET		3 SD
		5 PD
		1 not evaluable for response^a
Average SUVmean (dynamic) ≤ 1.5	5 (26 %)	2 PD
AND qualitatively negative sites detected on FES PET		3 not evaluable for response^b
Average SUVmean (dynamic) > 1.5	1 (5 %)	1 SD (index #10-015)
AND qualitatively negative sites detected on FES PET
