OBJECTIVES: The incidence of small-sized pulmonary adenocarcinomas with ground-glass opacity (GGO) has recently increased, with excellent postoperative prognosis. The limited resection of such cancers has been deemed to be acceptable based on retrospective studies. We conducted a prospective multi-institutional study evaluating the validity of limited resection for small-sized pulmonary adenocarcinoma with GGO. METHODS: The inclusion criteria were 25-80 years of age, no prior treatment, a maximum tumour diameter of 8-20 mm, a GGO ratio of ≥ 80%, clinical T1N0M0, lower 18F-fluorodeoxyglucose accumulation than the mediastinum, resectable by sublobar resection, pulmonary lobectomy tolerable and an intraoperative pathological diagnosis of bronchiloalveolar carcinoma...

A ground-glass opacity (GGO) lesion was discovered in a 64-year-old female 1 year ago. One month before administration, a follow-up CT showed the lesion in the apical segment of left upper lobe had increased from 8 to 11 mm in diameter. The lesion was diagnosed to be cT1aN0M0 non-small cell lung cancer (NSCLC) and a 3-port video-assisted thoracic surgery (VATS) anatomic segmentectomy was performed. Intraoperative frozen sections revealed a microinvasive adenocarcinoma. Systematic lymph node dissection was then carried out...

BACKGROUND: Alectinib, a second-generation anaplastic lymphoma kinase (ALK) inhibitor, is a key drug for ALK rearranged lung adenocarcinoma. Interstitial lung disease (ILD) is an important adverse effect of alectinib, which generally requires termination of treatment. However, we treated two patients with drug-induced ILD who continued to receive alectinib. CASE PRESENTATION: Patient 1 was a 57-year-old male with an ALK-rearranged Stage IV lung adenocarcinoma who was administered alectinib as first-line therapy...

Solitary pulmonary capillary hemangioma (SPCH) is a rare type of benign lung tumor, which must be distinguished from early lung cancer and precancerous lesions of the lung that manifest in a similar way upon imaging. The current study describes a case of SPCH and a review of the literature is performed. The patient was a 40-year-old Chinese woman who was referred to the Liaoning Cancer Hospital and Institute (Shenyang, China) in October, 2015 with a cough without obvious inducement. Computed tomography (CT) demonstrated pure ground glass opacity (GGO) in the right upper lung...

Julip Jung, Helen Hong, Jin Mo Goo
We propose a ground-glass nodule (GGN) segmentation method that can separate solid component and ground-glass opacity (GGO) using an asymmetric multi-phase deformable model in chest CT images. First, initial solid component and GGO were extracted using intensity-based segmentation with histogram modeling. Second, the initial extracted regions were refined using an asymmetric multi-phase deformable model with modified energy functional and intensity-constrained averaging function. Finally, vessel-like structures are removed based on multi-scale shape analysis...

The aim of this study was to investigate the impact of pixel-based machine learning (ML) techniques, i.e., fuzzy-c-means clustering method (FCM), and the artificial neural network (ANN) and support vector machine (SVM), on an automated framework for delineation of gross tumor volume (GTV) regions of lung cancer for stereotactic body radiation therapy. The morphological and metabolic features for GTV regions, which were determined based on the knowledge of radiation oncologists, were fed on a pixel-by-pixel basis into the respective FCM, ANN, and SVM ML techniques...

OBJECTIVES: Revised TNM classification has proposed a new clinical classification of lung cancers with multiple pulmonary sites. However, definition of the radiological findings and their prognostic impacts are still controversial. Therefore, we evaluated the prognostic impact of multiple lung cancers based on the radiologic classifications concluded from findings on thin-section computed tomography. METHODS: Among surgically resected 1440 c-stage I lung cancer patients, 246 (17...

Pulmonary cryptococcosis is most commonly reported in immunocompromised patients, whereas immunocompetent hosts are rarely affected and may be asymptomatic, resulting in reduced diagnostic performance of computed tomography (CT) imaging. Thus, the aim of the present study was to review the plain and contrast-enhanced chest CT scan findings of primary pulmonary cryptococcosis in immunocompetent patients, with the aim of improving the diagnosis of this type of pulmonary disease. In the present study, a total of 27 immunocompetent patients of clinically confirmed pulmonary cryptococcosis were analyzed retrospectively...

RATIONALE: Pulmonary alveolar proteinosis (PAP) is a rare lung disorder characterized by the abnormal accumulation of alveolar surfactant protein in alveolar spaces. Secondary PAP can result from myelodysplastic syndrome (MDS). PATIENT CONCERNS: But most reports described a single case; here we reported 2 cases of PAP secondary to MDS. One case developed secondary PAP at the same time as MDS, and the other developed during the course of MDS. DIAGNOSES: The diagnosis of PAP was made by bronchoalveolar lavage and based on the identification of periodic acid-Schiff-positive proteinaceous material...

Modern thoracic surgery requires the ability to manage patients with ground glass opacities (GGO). However, due to the lack of a standardize approach in our institution these cases are discussed in the tumor board. We here present our therapeutic rationale in a case of a patient with multiple GGOs, who underwent an en-bloc anatomic bisegmentectomy as surgical treatment for a synchronous lung adenocarcinoma.

Multifunctional nanoplatforms with multimodal imaging and cancer therapy capabilities have attracted attention in biomedical applications. Near-infrared persistent luminescence nanoparticles (NPLNPs) were considered one of the most promising candidates for constructing multifunctional nanoplatforms due to the absence of in situ excitation and high signal-to-noise ratios (SNRs). Here, we report a novel NPLNP mSiO2@Gd3Ga5O12:Cr(3+), Nd(3+) (mSiO2@GGO) as multifunctional nanoplatforms for multimodal imaging and cancer therapy...

OBJECTIVES: The lung is one of the most common organs of metastasis from colorectal cancer (CRC), and we have encountered lung cancer patients with a history of CRC. There have been few studies regarding methods used to discriminate between primary lung cancer (PLC) and pulmonary metastasis from CRC (PM-CRC) based only on preoperative findings. We retrospectively investigated predictive factors discriminating between these lesions in patients with a history of CRC. METHODS: Between 2006 and 2015, 117 patients with a history of CRC (44 patients with 47 PLC and 73 patients with 102 PM-CRC) underwent subsequent or concurrent resection of pulmonary lesions...

Angiosarcoma with pulmonary metastasis is a rare, fatal disease that often presents with multiple pulmonary nodules and diffuse alveolar hemorrhage. We herein review the detailed clinical characteristics of pulmonary metastatic angiosarcoma and determine a reasonable diagnostic strategy.The medical records of 11 patients with pulmonary angiosarcoma were reviewed.The mean age of the patients was 45.7 years (range, 30-71 years). All patients were male. The most common symptom was hemoptysis (8/11). Common initial misdiagnoses were tuberculosis (5/11), vasculitis (2/11), nontuberculous infectious disease (1/11), and constrictive pericarditis (1/11)...

BACKGROUND: It remains unclear whether a dominant lung adenocarcinoma that presents with multifocal ground glass opacities (GGOs) should be treated by local therapy. We sought to address survival in this setting and to identify risk factors for progression of unresected GGOs. METHODS: Retrospective review of 70 patients who underwent resection of a pN0, lepidic adenocarcinoma, who harbored at least 1 additional GGO. Features associated with GGO progression were determined using logistic regression and survival was evaluated using the Kaplan-Meier method...
