Long-term Follow-up Results from PET/CT Surveillance after Surgical Resection of Lung Adenocarcinoma Manifesting as Ground-glass Opacity: Notice of Retraction.

The authors have requested that the article “Long-term Follow-up Results from PET/CT Surveillance after Surgical Resection of Lung Adenocarcinoma Manifesting as Ground-glass opacity” be retracted. The authors found several critical errors in the article which were not detected before the publication. Specific details as follows:

Substantial number of patients in the study underwent postoperative follow-up with PET alone instead of PET/CT. PET/CT was installed in our institution in 2009 and PET (without CT component) was used before 2009. The authors misunderstood that all the patients in this study underwent PET/CT, but recently realized that this was incorrect. PET alone may be inferior to PET/CT for detection of small pulmonary lesions due to limited spatial resolution, and the mixed data from PET/CT and PET alone might have influenced our study results. The authors’ major concern is that the results from our study

Specific details for PET/CT (Methods: Image acquisition, page 2): The specific details regarding the PET/CT was described incorrectly. As stated above, PET alone (used before 2009) should have been included in the description. Additionally, the authors made a mistake in describing of the brand name for PET/CT (Gemini, Phillips). The PET/CT scanner used in this study was DVCT, GE healthcare.

Considering the mixed data (from PET alone and PET/CT), the title of this study (Long-term Follow-up Results from PET/CT Surveillance) is incorrect.

After discussion, the authors concluded that the study may give misinformation to the readers, and therefore they have decided to withdraw the article.
