Article Synopsis
- The text discusses a case of a 71-year-old man with heterotaxy syndrome, a condition causing symmetrical development of organs, who underwent surgery for non-small cell lung cancer.
- A CT scan revealed a rapidly growing tumor in his right middle lobe, alongside anatomical anomalies in the bronchi and pulmonary artery.
- The conclusion emphasizes the need for 3D-CT scans to better understand the unique anatomy in patients with heterotaxy syndrome prior to surgical procedures, as this specific anatomical variation had not been previously documented.
When a mass occurs at the staple line following lung resection, it can be difficult to distinguish between local cancer recurrence and granuloma. We present a case of a staple-line granuloma with 18F-fluorodeoxyglucose-positron emission tomography uptake and elevated serum carbohydrate antigen 19-9 (CA19-9) in a patient with ovarian cancer lung metastasis. After granuloma resection, serum CA19-9 levels normalized, and CA19-9 positive cells were identified in the resected tumor.

Immunohistochemistry (IHC) enables reliable diagnosis of histological types but requires more time and more tumor tissue slides than hematoxylin and eosin staining. We aimed to assess the clinical validity of a new rapid multiplex IHC technique utilizing alternating current (AC) mixing for intraoperative lung cancer diagnosis.

Although brain MRI, bone scintigraphy and whole-body PET/CT play important roles in detecting distant metastases, there is a lack of evidence regarding the indication for metastatic staging in early NSCLCs, especially ground-grass nodules (GGNs). Our aim was to determine whether checking for distant metastasis is required in cases of clinical T1N0 GGN.

Methods: In total, 649 surgical patients with lung cancer were retrospectively reviewed. To compare the clinical effectiveness of PV proximal ligation, the simple stapler group (290 patients) and the proximal ligation group (359 patients who underwent thread ligation at the pericardial reflection with/without a stapler) were analyzed.
