    • Abstract

    Background
    AIM: New classification of adenocarcinoma subtypes cannot be discriminated by PET/CT findings. The aim of this study was to evaluate the features of operable adenocarcinoma patients according to PET/CT findings.

    Methods
    METHODS: Medical records of 49 adenocarcinoma patients to whom PET-CT was applied for clinical staging between November 2009 and December 2011 were evaluated retrospectively.

    Results
    RESULTS: Mean tumor size was 3,51±1,70 and mean tumor SUV max value was 8,18±4,50. Tumor size and tumor SUV max values were not different between subtypes. Seventeen of the patients had positive and 8 had suspicious positive mediastinal lymph nodes, however only 16 of the positive N2 lymph nodes were determined to be pathologically positive by mediastinoscopy or thoracotomy. Tumor SUV max values were found to be correlated with tumor size (r=0,493, p<0,001). The most frequent subtype was unclassified (32 patients). The others were mixed (6), acinar (4), lepidic (3), mucinous (2), solid (1) and papillary (1) subtypes.

    Conclusion
    CONCLUSION: We need studies involving more patients to evaluate the differences between PET/CT uptakes of adenocarcinoma subtypes, although we observed an association with tumor size and SUV max values of the adenocarcinomas regardless from the histopathological subtypes.
