Objectives: Although positron emission tomography (PET) using F-18-fluorodeoxy-glucose (FDG) frequently gives false-negative results for slow-growing tumors, C-11-acetate (AC)-PET has been reported to be able to detect them. To determine the usefulness of AC-PET for imaging non-small cell lung cancers (NSCLCs), the sensitivity and specificity were compared between the AC-PET and FDG-PET with a Multicenter study.Materials and Methods: A total of 284 pulmonary lesions (227 NSCLCs and 57 benign lesions) were examined using both AC-PET and FDG -PET before surgery at seven Japanese institutes. The AC-or FDG-uptake in each lesion were quantitatively measured using the contrast ratio of the standard uptake value between the lesions and the contralateral lung.Results: The sensitivity of AC-PET for diagnosing NSCLC was 0.71, which was significantly higher than the value of 0.57 obtained by FDG-PET (p < 0.001). No significant difference in the specificity was seen between AC- and FDG-PFT. For the 146 well-differentiated adenocarcinomas. the sensitivity of AC-PET was 0.62, which was significantly higher than the value of 0.37 obtained by FDG-PET (p < 0.001). Of the 51 moderately- or poorly-differentiated adenocarcinomas and 30 nonadenocarcinomas, there was no significant difference of sensitivity between AC- and FDG-PET.Conclusions: AC-PET could be used in place of FDG-PET for imaging NSCLC, with higher sensitivity for well-differentiated adenocarcinoma compared with FDG-PET.
