Treatment Strategy Drawn from Results of FDG PET
| FDG PET | n | Treatment | ||||
|---|---|---|---|---|---|---|
| Surgery | 131I therapy | External irradiation | NCTO | NTN | ||
| True-positive* | 34 | 18 | 10 | 4 | 7 | 0 |
| False-positive | 7 | 2 | 0 | 0 | 0 | 5 |
| True-negative | 5 | 0 | 0 | 0 | 0 | 5 |
| False-negative | 15 | 3 | 1 | 0 | 11 | 0 |
↵* Figures in first line exceed number of patients because some patients got more than one treatment (e.g., surgery and external irradiation).
n = number of patients; NCTO = no curative treatment option available because of widespread disease; NTN = no treatment necessary.
