The progressive fibrosing (PF) phenotype of interstitial lung disease (ILD) is characterised by worsening respiratory symptoms, function, and extent fibrosis on high-resolution computed tomography. We aimed to investigate the prevalence clinical outcomes PF-ILD in a real-world cohort assess prognostic significance diagnostic criteria.Clinical data patients with ILD other than idiopathic pulmonary (IPF) consecutively diagnosed at single centre were retrospectively reviewed. A PF was defined...

Little is known about the standard care of small (<2 cm in diameter) pancreatic neuroendocrine tumors (PNET). The aim present study was to determine clinical outcomes PNET after endoscopic ultrasound (EUS)-guided ethanol-lipiodol ablation (EUS-ELA).In this prospective cohort study, consecutive patients who underwent EUS-ELA for were enrolled and followed ≥3 years. Treatment efficacy primary outcome measure.In total, 33 had 40 pathologically confirmed final analysis. A total 63 sessions...

Diffuse large B-cell lymphoma (DLBCL) is classified into prognostically distinct germinal center (GCB) and activated subtypes by gene expression profiling (GEP). Recent reports suggest the role of GEP in targeted therapy. Immunohistochemistry (IHC) algorithms have been proposed as surrogates GEP, but their utility remains controversial. Using microarray, we examined concordance 4 GEP-correlated 2 non-GEP-correlated IHC 381 DLBCLs, not otherwise specified. Subtypes variants DLBCL were...

The gastrointestinal tract is the most common primary extranodal site for diffuse large B-cell lymphoma (DLBCL).However, there no consensus on appropriate staging system intestinal DLBCL.We evaluated utility of modified Ann Arbor system, Lugano and Paris (a modification Tumor, Node, Metastases [TNM] epithelial tumors) in 66 cases resected DLBCL.The were treated with surgery, plus either cyclophosphamide, doxorubicin, vincristine, prednisolone (CHOP) chemotherapy alone (n = 26) or addition...

Objectives There is an increasing need for grading with small endoscopic ultrasound–guided fine needle aspiration biopsy (EUS-FNAB) specimens the proper diagnosis and therapy selection of patients unresectable pancreatic neuroendocrine tumors (PanNET). However, our understanding EUS-FNAB specimen limited compared surgically resected specimens. Methods We retrospectively determined Ki-67 labeling index (LI) 33 matched PanNETs digital image analyzer. Pairwise grades between PanNET were...

This study aimed to develop a deep learning (DL) model for predicting the recurrence risk of lung adenocarcinoma (LUAD) based on its histopathological features. Clinicopathological data and whole slide images from 164 LUAD cases were collected used train DL models with an ImageNet pre-trained efficientnet-b2 architecture, densenet201, resnet152. The trained classify each image patch into high-risk or low-risk groups, case-level result was determined by multiple instance final FC layer's...

Non-small cell lung cancer (NSCLC) is histologically classified into adenocarcinoma (LUAD) and squamous carcinoma (LSCC). However, some tumors are ambiguous other pathophysiological features or microenvironmental factors may be more prominent. Here we report integrative multiomics analyses using data for 229 patients from a Korean NSCLC cohort 462 previous studies. Histological examination reveals five molecular subtypes, one of which subtype with PI3K-Akt pathway upregulation, showing high...

Conventional chemotherapeutics exploit cancer hallmark of active cell cycling, primarily targeting mitotic cells. Consequently, the index (MI), representing proportion cells in mitosis, serves as both a prognostic biomarker for progression and predictive marker chemo-responsiveness. In this study, we developed transcriptome signature to predict chemotherapeutic responsiveness based on Active Mitosis Signature Enrichment Score (AMSES), computational metric previously established estimate...

Abstract Background Immunoglobulin G4-related lung disease (IgG4-RLD) is the pulmonary manifestation of a systemic fibroinflammatory characterized by lymphoplasmacytic infiltration with an abundance IgG4-positive plasma cells. Long-term clinical course and outcomes IgG4-RLD remain unclear. We aimed to identify characteristics, treatment outcomes, longitudinal function changes in patients according radiologic classification. Methods Chest computed tomography findings 37 subjects were...
