In response to the recommendation of the U.S. Preventive Services Task Force and the coverage decision by the Centers for Medicare and Medicaid Services for lung cancer screening (LCS) computed tomography (CT), the American College of Radiology introduced the Lung CT Screening Reporting and Data System (Lung-RADS) in 2014 to standardize the reporting and management of screening-detected lung nodules. As with many first-edition guidelines, questions arise when such reporting systems are used in daily practice...

BACKGROUND: Programmed death-ligand 1 (PD-L1) expression testing is recommended by guidelines for patients with advanced non-small cell lung cancer (NSCLC). The primary objective of the current study was to determine the success rate of PD-L1 testing from cytology cell block samples obtained by bronchoscopic needle aspiration. The secondary objective was the assessment of the difference in specimen adequacy acquired via needles of different gauges. METHODS: Patients with NSCLC who underwent bronchoscopic needle aspirations for which PD-L1 testing was requested between November 1, 2016, and February 6, 2017, were included in the current analysis...

PET/CT quantification of lung tissue is limited by several difficulties: the lung density and local volume changes during respiration, the anatomical mismatch between PET and CT and the relative contributions of tissue, air and blood to the PET signal (the tissue fraction effect). Air Fraction Correction (AFC) has been shown to improve PET image quantification in the lungs. Methods to correct for the movement and anatomical mismatch involve respiratory gating and image registration techniques. While conventional registration methods only account for spatial mismatch, the Jacobian determinant of the deformable registration transformation field can be used to estimate local volume changes and could therefore potentially be used to correct (i...

Indocyanine green fluorescent image-guided surgery was developed to identify primary and metastatic nodules of various malignancies. However, currently, surgeons need to identify the fluorescent image on a monitor, which impedes surgical procedures. Herein, we developed a novel projection mapping device that can cast the real-time fluorescent image onto the surface of the targeted organ. We performed surgical resection of a lung metastasis of hepatoblastoma using this technique. The projection mapping technique clearly detected the pulmonary lesion, and no other lesions were identified in the ipsilateral thorax...

OBJECTIVES: Segmentectomy by video-assisted thoracoscopic surgery (VATS) permits anatomical resection for diagnosis and treatment of small lung nodules but requires that intersegmental planes and segmental vessels be identified accurately. Near-infrared angiography with systemic injection of indocyanine green (ICG) can precisely identify the intersegmental plane. The purpose of this study was to confirm the usefulness of ICG angiography during VATS segmentectomy. METHODS: We retrospectively reviewed the records of 22 consecutive patients who underwent VATS segmentectomy performed with near-infrared angiography between November 2014 and October 2015...

RATIONALE: Lymphomatoid granulomatosis is a very rare Epstein-Barr virus-driven lymphoproliferative disease. This disease has high mortality owing to its low incidence in conjunction with nonspecific presentations, which contribute to delays in diagnosis. PATIENT: An 87-year-old male had a week-long history of intermittent fever and general weakness. A chest radiograph showed multifocal patchy consolidations with nodular lesions. DIAGNOSES: Open lung biopsy using video-assisted thoracic surgery resulted in a diagnosis of grade III lymphomatoid granulomatosis...

Lung cancer is the leading cause of cancer-related deaths in the world, and one of its manifestations occurs with the appearance of pulmonary nodules. The classification of pulmonary nodules may be a complex task to specialists due to temporal, subjective, and qualitative aspects. Therefore, it is important to integrate computational tools to the early pulmonary nodule classification process, since they have the potential to characterize objectively and quantitatively the lesions. In this context, the goal of this work is to perform the classification of pulmonary nodules based on image features of texture and margin sharpness...

Aquaporin-1 (AQP1) is a proangiogenic water channel protein promoting endothelial cell migration. We previously reported that AQP1 silencing by RNA interference reduces angiogenesis-dependent primary tumour growth in a mouse model of melanoma. In this study, we tested the hypothesis that AQP1 inhibition also affects animal survival and lung nodule formation. Melanoma was induced by injecting B16F10 cells into the back of C57BL6J mice. Intratumoural injection of AQP1 siRNA and CTRL siRNA was performed 10 days after tumour cell implantation...

BACKGROUND: Malignant fibrous histiocytoma is a sarcoma of uncertain origin that can be found both in soft tissues and in bones. It is currently called undifferentiated pleomorphic sarcoma not otherwise specified and it represents a final common pathway in several tumors that are subject to the progress of dedifferentiation. Local recurrence of the tumor in the same location where it was originated occurs in 20-30% of the total number of soft tissue sarcomas. It is less frequent in limbs and more likely to recur in retroperitoneal sarcomas and in head and neck...

Surgery still remains the main stream in the multimodality treatment for locally advanced lung cancer. On the other hand, more than 50% of non-small cell lung cancer are excluded for surgical indications, especially T4 category of lung cancer. In this study, we showed 5 year overall survival rate of both 50 clinical T4 cases and 30 pathological T4 cases are 35.6% and 41.9% respectively. Those could be compared with the non-surgical treatment results in the literature. Through this study and analysis of other reports, we might consider surgical indications for T4 category lung cancer are as follows;invasion to mediastinum, spine, trachea, carina and additional nodules in ipsilateral different lobes with N0-1 status(esophagus is not included in this study)...

BACKGROUND: The similar clinical and computed tomography (CT) characteristics of cryptogenic organising pneumonia (COP) and chronic eosinophilic pneumonia (CEP) make precise diagnosis challenging. OBJECTIVES: To help differentiate between COP and CEP using high-resolution CT (HRCT). DESIGN: Clinical data and HRCT images of COP and CEP patients referred to Masih Daneshvari Hospital, Tehran, Iran, from 2007 to 2015 were reviewed. Diagnosis of COP or CEP was confirmed using open lung biopsy or a combination of transbronchial biopsy, bronchoalveolar lavage fluid (BALF) analysis, peripheral eosinophilia and a favourable response to corticosteroids...

The malignancy risk differentiation of pulmonary nodule is one of the most challenge tasks of computer-aided diagnosis (CADx). Most recently reported CADx methods or schemes based on texture and shape estimation have shown relatively satisfactory on differentiating the risk level of malignancy among the nodules detected in lung cancer screening. However, the existing CADx schemes tend to detect and analyze characteristics of pulmonary nodules from a statistical perspective according to local features only. Enlightened by the currently prevailing learning ability of convolutional neural network (CNN), which simulates human neural network for target recognition and our previously research on texture features, we present a hybrid model that takes into consideration of both global and local features for pulmonary nodule differentiation using the largest public database founded by the Lung Image Database Consortium and Image Database Resource Initiative (LIDC-IDRI)...

BACKGROUND: Timely care of lung cancer is presumed critical, yet clear evidence of stage progression with delays in care is lacking. We investigated the reasons for delays in treatment and the impact these delays have on tumor-stage progression. METHODS: We queried our retrospective database of 265 veterans who underwent cancer resection from 2005 to 2015. We extracted time intervals between nodule identification, diagnosis, and surgical resection; changes in nodule radiographic size over time; final pathologic staging; and reasons for delays in care...

Mutations of the COPA gene cause an immune dysregulatory disease characterised by polyarticular arthritis and progressive interstitial lung disease with pulmonary haemorrhages. We report the case of a young girl that presented at age 3 with polyarticular arthritis, chronic cough and high titer rheumatoid factor. Radiologic imaging showed interstitial lung disease with tree-in-a-bud nodules and air-filled cysts. Targeted genetic analysis of COPA gene showed the reported c.698G>A mutation. The patient was lost to follow up for 3years during which therapy was discontinued with the development of joint damage and deformities...
