Table 2.
FDG PET staged 16/70 patients incorrectly compared to final baseline stage. Patients who received FDG PET imaging prior to surgery or who did not receive surgical treatment are included (n = 70). The table indicates the number of patients with their corresponding stage. (A) Staging based on clinical assessment, pathology and conventional imaging performed at baseline. (B) Staging based on FDG PET imaging. (C) Final stage determined after FDG PET imaging, additional imaging and/or biopsy/cytology of new identified suspect lesions.
