Comparative Study
An analysis of clinical characteristics and prognosis for patients with serum alpha-fetoprotein-positive gastric cancer.
The aim of this analysis was to investigate the clinical characteristics and prognosis of patients with serum alpha-fetoproteinpositive gastric cancer (AFPGC) in order to improve the diagnosis and treatment. ⋯ It is more malignant in patients with serum AFPGC than in those with serum alpha-fetoprotein-negative gastric cancer. There are later clinical stage, poorer differentiation, larger tumor volume, and higher incidence of metastasis to the liver and lymph nodes in patients with serum AFPGC, with low survival rate and poor prognosis.

Lung volume reduction coil (LVRC) treatment is a minimally-invasive technique planned to achieve an improvement of exercise capacity and pulmonary function in subjects with advanced emphysema and hyperinflation. It has been proposed together with other bronchoscopic lung volume reduction approaches to reduce lung hyperinflation in emphysema as less invasive alternatives to LVRS and are currently under clinical investigation. Following the successful early experiences in previous pilot trials, recent studies allow further investigation into the feasibility, safety and efficacy of LVR coil treatment in a multi-center setting in a larger group of patients. ⋯ The literature on endobronchial coils continues to look promising with an acceptable safety profile, and positive long-term follow-up data are certainly more and more available. However, further well-designed, blinded, placebo (or sham) controlled trials, and even randomized trials against LVRS (lung volume reduction surgery), are needed before routine clinical use can be recommended. This is true not only for endobronchial coils, but also for the whole field of bronchoscopic lung volume reduction.

Idiopathic pulmonary fibrosis (IPF) is a rare chronic and ultimately fatal disease resulting in an aberrant scarring and thickening of lung tissue. Molecular pathogenetic mechanisms of IPF are still unknown and till now no effective therapy is known to really improve disease's outcome. ⋯ The work is focused on how gene expression analysis can be applied to stratify IPF cases based on their risk of disease progression. Moreover they tried to match genetic and phenotypic profiles in order to predict therapeutic response and patients' prognosis.

Long non-coding RNA PVT1 (lncRNA PVT1) has been identified and it plays an oncogenic role in various human cancers. However, its roles in pancreatic cancer remain unclear. The aim of this paper was to explore the PVT1 expression levels and relationship with survival of patients with pancreatic ductal adenocarcinoma (PDAC) and to establish the significance of PVT1 in the development and progression of PDAC. ⋯ The study findings suggested that the increased expression of lncRNA PVT1 in PDAC was correlated with tumor progression, and PVT1 might be a potential molecular biomarker for predicting the prognosis of patients with PDAC.

Sarcoidosis is a benign disease of unknown etiology that is characterized by the formation of noncaseating epithelioid cell granulomas. Although a multisystemic disease, it primarily affects the lung and the lymphatic system of the body. When a histological diagnosis is required, bronchoscopy is frequently employed because allows tissue sampling from several anatomic sources, such as airways, lung parenchyma and hilar/mediastinal nodes. ⋯ The Authors demonstrated that the yield of cTBNA added to EBB and TBLB is similar to EBUS-TBNA plus transbronchial biopsies, although ultrasound guided transbronchial needle aspiration shows the best single diagnostic efficacy. In this review article we aimed to discuss the findings by Gupta in the context of medical literature, highlighting the importance of adding nodal aspirations (with or without ultrasound guidance) with bronchial and transbronchial samples to gain the optimal sensitivity in obtaining histological confirmation. We finally pointed out the need for future studies to evaluate the potential role of rapid on-site evaluation (ROSE) of needle aspirates in reducing additional sampling and related costs and complications.
