Percutaneous cryoablation under imaging guidance has been proved to be a safe and effective method for ablation and debulking of tumors, providing radical cure or palliation, as the case may be, for patients with different stages of disease. The local control rate is high with cryoablation, and the complications are usually controllable, making it a reasonable choice in lung cancer treatment. In this paper the technique and mechanism of action of cryoablation are summarized, and studies performed on the application of percutaneous cryoablation in various stages of lung cancer are reviewed...

BACKGROUND: Pneumocystis jirovecii pneumonia (PCP) is a frequent opportunistic infection in immunocompromised patients. In literature, presentation and outcome of PCP differs between patients with human immunodeficiency virus (HIV) infection and renal transplant recipients (RTRs). METHODS: We conducted a cross-sectional study of patients with PCP based on the HIV and renal transplant registries at our institution. Radiological and clinical data from all confirmed PCP cases between 2005 and 2012 were compared...

BACKGROUND: Localization of small, nonvisible and nonpalpable nodules is challenging during video-assisted thoracoscopic surgery. We evaluated the feasibility of using a new ultrasound thoracoscope to localize nodules in resected ex vivo human lungs. METHODS: The tumor was localized and measured in its greatest dimension with a prototype ultrasound thoracoscope (XLTF-UC180; Olympus Corporation, Tokyo, Japan) at different frequencies (5.0 to 12.0 MHz) and different lung specimen states (deflated, semiinflated)...

OBJECTIVES: To evaluate the performance of a commercially available CAD system for automated detection and measurement of subsolid nodules. MATERIALS AND METHODS: The CAD system was tested on 50 pure ground-glass and 50 part-solid nodules (median diameter: 17mm) previously found on standard-dose CT scans in 100 different patients. True nodule detection and the total number of CAD marks were evaluated at different sensitivity settings. The influence of nodule and CT acquisition characteristics was analyzed with logistic regression...

PURPOSE: The solid component of lung ground-glass nodules on thin-section computed tomography (TSCT) reflects cancer cell progression and invasiveness. The purpose of this study was to clarify the cut-off value of preoperative TSCT findings in treating a lesion suspected of being adenocarcinoma and to recognize the timing of surgical resection for lung nodules. METHODS: We reevaluated the TSCT findings in 392 patients with clinical stage IA lung adenocarcinoma who underwent surgical resection between 2003 and 2007...

Background Less invasive adenocarcinomas (LIAs) of the lung, including adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA), are indications of sublobar resection and has a 5-year disease-free survival rate of almost 100% after surgery. By distinguishing invasive adenocarcinoma from LIA with computed tomography (CT) characteristics, it is possible to determine the extent of resection and prognosis for patients with ground-glass nodules (GGNs) before surgery. Methods We reviewed CT and pathological findings of 728 GGNs in 645 consecutive patients who received curative lung resection in a single center...

We retrospectively evaluated whether preoperative percutaneous transthoracic needle biopsy (PTNB) affected the incidence of pleural recurrence in pathological stage I lung cancer patients. Pleural recurrence occurred in pure solid nodule (PSN) cases but not in ground-glass nodule cases, as evaluated using thin-section computed tomographic imaging. When the cases were restricted to sub-pleural PSN, the incidence of recurrence tended to be higher in a PTNB group (63 patients diagnosed by PTNB) than in a non-PTNB group (86 patients diagnosed by transbronchial biopsy or intraoperative diagnosis) (25% vs...

BACKGROUND: Visceral pleural invasion (VPI) had been demonstrated as an aggressive sign in non-small cell lung cancers (NSCLC). However, its incidence and clinical relevance in early lung cancer showing ground glass nodules (GGNs) has not been clarified. METHODS: All consecutive surgically treated patients with solitary GGNs between 2009 and 2013 were reviewed retrospectively. Inclusion criteria were defined as lesions ≤3 cm with pleura abutting on computed tomography (CT) scan and pathologically confirmed NSCLC...

Solitary pulmonary capillary hemangioma (SPCH) is a rare disease, first described about autopsy cases in 2000 and about surgically resected cases in 2006. To date, only 9 surgically resected cases have been published in English. Here, we report 7 original cases with surgery (median age, 54 y; 4 females, 2 never-smokers). All patients were asymptomatic, and all nodules were detected by computed tomography (CT). The median (range) size of nodule was 11 (8 to 16) mm. Six of 7 cases showed the part-solid nodule appearance and 1 showed pure ground-glass nodule appearance in CT findings...
