摘要: Objective: We investigated the association of diagnostic accuracy for preoperative clinical stage lung adenocarcinoma with its histologic subtype micropapillary pattern (MPA) or non-micropapillary (NMPA). Methods: evaluated 303 patients pathologic who underwent 18Ffluorodeoxyglucose positron emission tomography (FDG-PET) scanning, from 2008 to 2013, before undergoing surgical resection. Patients had been and were classified by MPA NMPA. Results: There was a significant difference in postoperative up-staging between NMPA (P < 0.0001) cases. In addition, there frequency upgrading lymph node (N) factor 0.0001), but not tumor (T) = 0.8271). Postoperative N up-grading observed more frequently Conclusion: adenocarcinoma, some metastases undetectable imaging studies and, consequently, patients. While FDG-PET is useful evaluation spread lesion, it necessary conduct treatment while remembering that metastasis difficult detect patients, depending on histological subtype.
