Table 3. Relation between fluorescence imaging and final histopathology.

Patient No.	Primary tumor		Lymph nodes		Omentum		Other biopsies
	PA	Fluorescent (TBR)	PA	Fluorescent (TBR)	PA	Fluorescent (TBR)	PA	Fluorescent (TBR)
1	Malignant	Yes* (3.2)	Malignant (16/22)**	Yes, all (6.3)	Benign	No	Benign	No
2	Malignant	Yes* (13)	Benign	Yes, some (3.0)	Benign	No	Benign	No
3	n/a	n/a	Benign	Yes, some (1.8)	Benign	No	Benign	No
4	Malignant	Yes* (2.9)	n/a	n/a	Malignant***	Yes, all (2.4)	n/a	n/a

Abbreviations: n/a = not applicable; TBR = tumor-to-background, shown as mean; ^*a fluorescence signal arising from the uterus was seen during surgery ^**in 16/22 lymph nodes macrometastases were found; ^***two omental depositions were identified on preoperative imaging, but during surgery a third lesion was identified solely by NIR fluorescence imaging. Final histopathological analysis showed tumor cells in all three omental lesions.
