    BACKGROUND: Osteopenia was recently reported to be a factor contributing to a poorer prognosis in various cancers. However, its prognostic impact on non-small cell lung cancer (NSCLC) patients remains unclear. In the present study, we focused on osteopenia in elderly NSCLC patients and investigated survival outcomes. METHODS: This study included 315 NSCLC patients aged 75 years or older who had undergone radical lobectomy or segmentectomy at our institution between 2010 and 2023. Osteopenia was evaluated based on the average pixel density within a circle in the mid-vertebral core at the 11th thoracic vertebra on preoperative computed tomography. RESULTS: Osteopenia was identified in 126 patients (40%). This osteopenia group had significantly poorer overall survival (OS) than the non-osteopenia group (5-year OS: 71.4%vs 81.0%, p = 0.026). Multivariable analysis revealed that Charlson comorbidity index (CCI) ≥ 2 (p = 0.020), Brinkman index (BI) ≥ 400 (p < 0.001), pathological Stage ≥ II (p < 0.001), and osteopenia (p = 0.016) were independent factors affecting OS. The cumulative incidence of non-lung cancer mortality was significantly higher in the osteopenia group than non-osteopenia group (5-year mortality rate: 16.9% vs. 6.4%, p = 0.005). In multivariable analysis, CCI ≥ 2 (p = 0.009), BI ≥ 400 (p < 0.008) and osteopenia (p = 0.001) were independent factors affecting non-lung cancer mortality. CONCLUSIONS: Elderly patients with osteopenia have significantly poorer OS, and osteopenia was closely associated with non-lung cancer mortality. Screening for osteopenia may assist in identifying high-risk patients of non-lung cancer death and developing appropriate treatment strategies.

  • Psoas Muscle Volume Is a Useful Predictor of Postoperative Outcome in Elderly Patients With Non-Small Cell Lung Cancer

    BACKGROUND: As the population ages, the number of elderly lung cancer patients has been increasing. While surgery is the best treatment for resectable lung cancer, elderly patients often have multiple comorbidities, making accurate preoperative risk assessment crucial when formulating an appropriate treatment plan. This study aims to explore how psoas muscle volume relates to postoperative outcomes in elderly lung cancer patients. METHODS: This single-center, retrospective study included 344 elderly (≥ 75) patients who underwent complete surgical resection for non-small cell cancer between 2010 and 2023. The psoas muscle volume index (PVI, cm3/m3) was measured using a 3-dimensional imaging workstation based on preoperative computed tomography images and grouped based on the median value for each gender. Postoperative complications and survival rates were then compared between the groups. RESULTS: The median PVI was 60.5 cm3/m3 for males and 47.7 cm3/m3 for females. The PVI-high group had significantly fewer complications (15.6%) than the PVI-low group (37.1%) (p < 0.001). The 5-year overall survival (OS) rate was higher in the PVI-high group (80.5%) than in the PVI-low group (66.7%) (p = 0.01). Multivariate analyses showed that PVI-high was an independent predictor of lower complication risk (odds ratio 0.28, p < 0.001) and an independent factor that improved OS (hazard ratio 0.60, p = 0.042). CONCLUSIONS: PVI in elderly lung cancer patients is associated with postoperative complications and survival.

    PURPOSE: Predicting perioperative complications in high-risk elderly patients with lung cancer has become increasingly important as the population ages. This study investigated the relationship between preoperative diaphragmatic thickness (DT) and perioperative complications. METHODS: We enrolled 101 patients ≥ 75 years old who had undergone radical resection for primary lung cancer between 2013 and 2018. Bilateral DT was measured on axial and coronal computed tomography, and the mean DT (MDT) was calculated based on these measurements. Outcomes were assessed based on postoperative complications, defined as Clavien-Dindo classification ≥ 2. RESULTS: The MDT was 3.51 ± 1.00 mm. Thirteen patients who experienced postoperative respiratory complications had a significantly lower MDT than a higher MDT (p = 0.0390). Multivariate logistic regression analyses revealed that an MDT ≤ 3.63 mm was an independent factor associated with postoperative complications (odds ratio, 5.559). CONCLUSIONS: Patients with a low MDT are at an increased risk of postoperative complications. Therefore, these patients require careful perioperative management.

    <p><b>INTRODUCTION:</b> Pulmonary cavernous hemangioma (PCH) is extremely rare and, due to the lack of specific radiological characteristics, is often misdiagnosed as other pulmonary diseases, including metastatic tumors. Here, we report a case of multiple PCH lesions with concomitant hepatic cavernous hemangioma (HCH), emphasizing the diagnostic implications of imaging findings.</p><p><b>CASE PRESENTATION:</b> A 57-year-old man presented with fever. CT revealed numerous well-circumscribed pulmonary nodules and multiple low-density hepatic lesions. Dynamic contrast-enhanced CT demonstrated mild, nonspecific enhancement of the pulmonary nodules, whereas the hepatic lesions showed enhancement from the center to the periphery. Serum tumor markers were within normal limits, and PET-CT revealed no abnormal fluorodeoxyglucose uptake in any of the lesions. Although the hepatic lesions appeared suggestive of hemangioma on imaging, the possibility of malignancy, such as hepatic angiosarcoma and its pulmonary metastases, could not be completely ruled out. Therefore, both hepatic and pulmonary biopsies were performed, and histopathological examination confirmed cavernous hemangioma in both organs.</p><p><b>CONCLUSIONS:</b> PCH is a rare benign tumor lacking distinctive imaging characteristics; therefore, differentiation from metastatic pulmonary tumors is often challenging and represents a key diagnostic issue. Although definitive diagnosis currently relies on surgical biopsy, combining suggestive imaging findings—such as the presence of microcalcifications within nodules and the absence of fluorodeoxyglucose uptake on PET-CT—may help avoid unnecessary invasive procedures.</p>

    BACKGROUND: Anatomical abnormalities in the pulmonary vessels have long aroused great interest among thoracic surgeons, and numerous variations of pulmonary vessels have been reported. Heterotaxy syndrome is an anatomical abnormality in which typically asymmetrical organs, including the lungs, develop symmetrically. We report the case of a 71-year-old man with heterotaxy syndrome undergoing radical lobectomy in the treatment of non-small cell lung cancer. CASE PRESENTATION: Computed tomography (CT) revealed an irregular nodule 25 mm in diameter in the right middle lobe. Two months later, at his first visit to our University Hospital, CT revealed a rapidly growing tumor 60 mm in diameter. In addition, three-dimensional (3D) CT revealed the upper and middle lobar bronchi forming a common trunk with the mediastinal type of the right pulmonary artery (PA). The patient underwent video-assisted right middle lobectomy + systematic complete hilar and mediastinal lymph node dissection. The interlobar fissure between the right upper and middle lobes was incomplete, and the common trunk formed by the upper-middle bronchus emerged from an area between the right PA (A1+3) and the right superior pulmonary vein. CONCLUSION: The finding of A4+5 branching from the right main PA and descending posterior to the right upper-middle bronchus, which formed a common trunk, resembled a mirror image of the normal left lung. To our knowledge, a common trunk with the mediastinal type of the right PA has never been reported during video-assisted right middle lobectomy. In patients with heterotaxy syndrome, 3D-CT to preoperatively understand their anatomy is essential.
