Changes in N-/M-staging after FAPI-46/dual-tracer PET/CT and changes of treatment
Changes in N-/M-staging and changes of treatment, A: nodal status, box on the left: N-stage (0–3) according to initial CT staging, box on the right: N-stages (0–3) after FAPI-46/dual-tracer PET/CT; colored lines indicate stage migration B: M-stage, left box: M-stage according to CT-staging, right box: M-stage according to FAPI-46/dual-tracer PET/CT; C: changes of treatment, “major”: change of treatment regimen (e.g. from curate to palliative), “minor”: changes in RT-field (enlargement/inclusion of nodal areas after FAPI-46/dual-tracer PET/CT).
