Subsolid pulmonary nodules are commonly encountered in lung cancer screening and clinical routine. Compared to other nodule types, subsolid nodules are associated with a higher malignancy probability for which the size and mass of the nodule and solid core are important indicators. However, reliably measuring these characteristics on computed tomography (CT) can be hampered by the presence of vessels encompassed by the nodule, since vessels have similar CT attenuation as solid cores. This can affect treatment decisions and patient management...

BACKGROUND: Minimally invasive video-assisted thoracoscopic surgery for small-sized pulmonary nodules is challenging, and image-guided preoperative localisation is required. Near-infrared indocyanine green fluorescence is capable of deep tissue penetration and can be distinguished regardless of the background colour of the lung; thus, indocyanine green has great potential for use as a near-infrared fluorescent marker in video-assisted thoracoscopic surgery. METHODS: Thirty-seven patients with small-sized pulmonary nodules, who were scheduled to undergo video-assisted thoracoscopic wedge resection, were enrolled in this study...

BACKGROUND: A hook wire has been most widely used for computed tomography (CT)-guided localization before video-assisted thoracoscopic surgery (VATS). However, microcoils have been suggested to replace wires. The purpose of this study was to compare the efficacy, VATS procedure time, and excised volume of specimens of CT-guided localization using a hook wire and microcoil. METHODS: The medical records of 106 patients with 110 pulmonary nodules who underwent CT-guided localization using a hook wire (group A) or microcoil (group B) before VATS performed between March 2013 and January 2017 were retrospectively reviewed...

Diffuse pulmonary ossification (DPO) is a rare disease characterized by metaplastic bone formation in the lung. There are few reports with a long-term follow-up of this disease. We herein report a 47-year-old man diagnosed with idiopathic DPO at 30 years of age. The patient's vital capacity was normal until 36 years of age (3.39 L, 82.4% predicted), but it was severely decreased when he visited the hospital again at 47 years of age due to cough and dyspnea (1.98 L, 44.6% predicted). Chest computed tomography showed a significant increase in the number of high-density nodules, suggesting that the progression of DPO had caused restrictive ventilatory impairment...

The overall survival of children with solid tumors has shown a substantial increase in the past decades due to progress in all of the disciplines involved in the treatment. The poor prognosis for advanced stages of disease and the morbidity related to therapeutic procedures are still a challenge. Innovations in the surgical treatment of solid tumors can contribute to increase the survival rate of affected children and to decrease the treatment-related morbidity. Considering these aspects, the successful implementation of innovations is described based on four examples...

Low-dose computed tomography (CT) scan is the only modality currently considered acceptable for lung cancer screening in high-risk populations. Screening recommendations vary. The US Preventive Services Task Force recommends annual low-dose CT scan to screen high-risk patients (ie, asymptomatic patients ages 55 to 80 years with a 30 pack-year smoking history and who currently smoke or have quit within the previous 15 years). The American Academy of Family Physicians recommends a shared decision-making discussion between the clinician and patient regarding the benefits and potential harms of screening...

Newly-appearing lung nodules on surveillance imaging in patients with pre-existing lung cancer can present a diagnostic dilemma when attempting to differentiate between metastatic disease, infection, and other inflammatory conditions. Here we report a case of an EGFR-/ALK-/BRAF+ metastatic adenocarcinoma patient who underwent lung biopsy for evaluation of upper-lobe predominant lung nodules revealed to represent pulmonary Langerhans cell histiocytosis (PLCH). The patient was a heavy smoker and admitted to increase her smoking habit after initially learning about her diagnosis with lung cancer...

Interferon γ (IFN-γ), a multifunctional cytokine, was upregulated in the resected gastric cancer tissue. However, whether IFN-γ is involved in the regulation of gastric cancer has not been well elucidated. Herein, we aimed to investigate the effects and mechanism of IFN-γ on gastric cancer. In this study, we found a vital role of IFN-γ in enhancing proliferation, inhibiting apoptosis, and promoting cell migration and invasion in gastric cancer cells SGC-7901 and MGC-803. Additionally, IFN-γ activated nuclear factor κB (NF-κB) signaling pathway by upregulating the phosphorylation expression of p65 and IκBα, and induced the expression of integrin β3 in vitro...
