TABLE 1.
Overview of Strategy for Intraoperative Tissue Sampling and Spectrometry
| Location | Fluorescence quality | Selection of areas | Spectrometry | Biopsy |
|---|---|---|---|---|
| Tumor core | Strong | 2 | 1× per area | 1 |
| Weak | 2 | 1× per area | 1 | |
| None | 2 | 1× per area | 1 | |
| Tumor margin | Strong | 2 | 1× per area | 1 |
| Weak | 2 | 1× per area | 1 | |
| None | 2 | 1× per area | 1 | |
| Normal tissue | None | 3 | 1× per area | 1 (optional) |
Theoretical maximum number of measurements. Two spectra were obtained from each selected area and averaged. Biopsies in “normal” tissue were only collected if this tissue was intended for resection.
