Surgical Method | F0 Resection | F1 Resection | F2 Resection |
---|---|---|---|
Bright light surgery | 0 | 7 (36.8%) | 12 (63.2%) |
Fluorescence guided surgery | 4 (20%) | 15 (75%) | 1 (5%) |
An F0 resection was defined as a complete absence of tumor in the postsurgical bed as detected by fluorescence at 14x magnification using the OV-100 image and image J software. A postoperative tumor burden >0 mm2 but less than 1 mm2 was defined as an F1 resection (microscopic disease). Gross disease (tumor burden >1 mm2) was categorized as an F2 resection.
