[CONCLUSIONS] NSCLC localized in the apicoposterior segment of the upper lobes of the lung tends to be adenocarcinoma, while those localized in the anterior segment tend to be squamous cell carcinoma. Tumor size less than 3 cm with apicoposterior localization is independently associated with the adenocarcinoma histological subtype.
[BACKGROUND] Studies have shown that malignant pulmonary nodules frequently occur in the upper lobes of the lung.

Abstract
[BACKGROUND] Studies have shown that malignant pulmonary nodules frequently occur in the upper lobes of the lung. However, there is no data on their distribution according to segments. The aim of this study is to predict the histological subtype of lung cancer based on the segment localization of malignant pulmonary nodules located in the upper lobe of the lung.
[METHODS] Between March 1, 2018, and November 1, 2024, 2402 patients who applied to the pulmonary diseases outpatient clinic and were scheduled for further investigation after thoracic CT scans revealed pulmonary nodules measuring 8 mm or larger were screened. The demographic characteristics, pulmonary nodule size, and histological subtypes of 154 patients diagnosed with non-small cell lung cancer (NSCLC) in further investigations were compared according to the upper lobe segments of the lung: apicoposterior and anterior.
[RESULTS] Adenocarcinoma percentage was significantly higher in the apicoposterior group, while squamous cell carcinoma percentage was significantly higher in the anterior group (p = 0.010).
[CONCLUSIONS] NSCLC localized in the apicoposterior segment of the upper lobes of the lung tends to be adenocarcinoma, while those localized in the anterior segment tend to be squamous cell carcinoma. Tumor size less than 3 cm with apicoposterior localization is independently associated with the adenocarcinoma histological subtype.
