Integrated multiomics signatures to optimize the accurate diagnosis of lung cancer.

Diagnosing lung cancer from indeterminate pulmonary nodules (IPLs) remains challenging. In this multi-institutional study involving 2032 participants with IPLs, we integrate the clinical, radiomic with circulating cell-free DNA fragmentomic features in 5-methylcytosine (5mC)-enriched regions to establish a multiomics model (clinic-RadmC) for predicting the malignancy risk of IPLs. The clinic-RadmC yields an area-under-the-curve (AUC) of 0.

Non-invasive prediction for pathologic complete response to neoadjuvant chemoimmunotherapy in lung cancer using CT-based deep learning: a multicenter study.

Neoadjuvant chemoimmunotherapy has revolutionized the therapeutic strategy for non-small cell lung cancer (NSCLC), and identifying candidates likely responding to this advanced treatment is of important clinical significance. The current multi-institutional study aims to develop a deep learning model to predict pathologic complete response (pCR) to neoadjuvant immunotherapy in NSCLC based on computed tomography (CT) imaging and further prob the biologic foundation of the proposed deep learning signature. A total of 248 participants administrated with neoadjuvant immunotherapy followed by surgery for NSCLC at Ruijin Hospital, Ningbo Hwamei Hospital, and Affiliated Hospital of Zunyi Medical University from January 2019 to September 2023 were enrolled.

[F]FDG PET-CT radiomics signature to predict pathological complete response to neoadjuvant chemoimmunotherapy in non-small cell lung cancer: a multicenter study.

Objectives: This study aims to develop and validate a radiomics model based on F-fluorodeoxyglucose positron emission tomography-computed tomography ([F]FDG PET-CT) images to predict pathological complete response (pCR) to neoadjuvant chemoimmunotherapy in non-small cell lung cancer (NSCLC).

Materials And Methods: One hundred eighty-five patients receiving neoadjuvant chemoimmunotherapy for NSCLC at 5 centers from January 2019 to December 2022 were included and divided into a training cohort and a validation cohort. Radiomics models were constructed via the least absolute shrinkage and selection operator (LASSO) method.

Characterization of fatty acid metabolism-related lncRNAs in lung adenocarcinoma identifying potential novel prognostic targets.

Lung adenocarcinoma (LUAD), a malignant respiratory tumor with an extremely poor prognosis, has troubled the medical community all over the world. According to recent studies, fatty acid metabolism (FAM) and long non-coding RNAs (lncRNAs) regulation have shown exciting results in tumor therapy. In this study, the original LUAD patient data was obtained from the TCGA database, and 12 FAM-related lncRNAs (AL390755.

A novel LUAD prognosis prediction model based on immune checkpoint-related lncRNAs.

Lung adenocarcinoma (LUAD) is a malignant disease with an extremely poor prognosis, and there is currently a lack of clinical methods for early diagnosis and precise treatment and management. With the deepening of tumor research, more and more attention has been paid to the role of immune checkpoints (ICP) and long non-coding RNAs (lncRNAs) regulation in tumor development. Therefore, this study downloaded LUAD patient data from the TCGA database, and finally screened 14 key ICP-related lncRNAs based on ICP-related genes using univariate/multivariate COX regression analysis and LASSO regression analysis to construct a risk prediction model and corresponding nomogram.

Sintilimab plus chemotherapy achieved symptom relief in stage IV lung squamous cell carcinoma with superior vena cava syndrome: a case report.

Lung cancer is the second most common and mortality disease in the world. Most patients with lung cancer are already at the advanced stage when diagnosed. There are multiple treatments for advanced lung cancer.

Compression of superior vena cava and azygos vein by a giant mediastinal mature cystic teratoma: a case report.

Teratoma is a common type of mediastinal tumor, often located in the anterior mediastinum. Mediastinal teratomas often occur in young and middle-aged people, and account for 5-21.5% of mediastinal tumors.

Screening and evaluation of the role of immune genes of brain metastasis in lung adenocarcinoma progression based on the TCGA and GEO databases.

Background: Brain metastasis was one of the factors leading to the poor long-term prognosis of patients with lung adenocarcinoma (LUAD).

Methods: The expression levels of immune genes in LUAD and LUAD brain metastases tissues were analyzed in GSE161116 dataset using the GEO2R, and the levels of differential immune genes in normal lung and LUAD tissues were verified. The biological functions and signaling mechanisms of the differential immune genes were explored via Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis.

Porcupine inhibitor LGK‑974 inhibits Wnt/β‑catenin signaling and modifies tumor‑associated macrophages resulting in inhibition of the malignant behaviors of non‑small cell lung cancer cells.

Tumor‑associated macrophages (TAMs) are critical components of the tumor microenvironment that are tightly associated with malignancies in human cancers, including lung cancer. LGK‑974, a small molecular inhibitor of Wnt secretion, was reported to block Wnt/β‑catenin signaling and exert anti‑inflammatory effects by suppressing pro‑inflammatory gene expression in cancer cells. Although it was reported that Wnt/β‑catenin was critical in regulating TAMs, it is still largely unknown whether LGK‑974 regulates tumor malignancies by regulating TAMs.

Evaluation of clinical value and potential mechanism of MTFR2 in lung adenocarcinoma via bioinformatics.

Background: Mitochondrial fission regulator 2 (MTFR2) was involved in the progression and development of various cancers. However, the relationship between MTFR2 with lung adenocarcinoma (LUAD) had not been reported. Herein, this study analyzed the clinical significance and potential mechanisms of MTFR2 in LUAD via bioinformatics tools.

Bilateral secondary pulmonary tuberculosis complicated with bilateral chylothorax: a case report.

A 26-year-old female was admitted to the emergency department of thoracic surgery complaining of chest tightness, shortness of breath, and a history of bilateral tuberculosis. A chest Computed Tomography (CT) scan showed bilateral pleural effusion. After that, the patient was implanted with bilateral intercostal drainage tubes.

Thoracic endometriosis: a case report and review of the literature.

Thoracic endometriosis is characterized by the presence of normal functioning endometrial tissues in normal pleural, diaphragm, or lung parenchyma, and main clinical symptoms include pneumothorax, menstrual hemothorax, menstrual hemoptysis, and pulmonary nodules. Chest X-ray (CXR), computed tomography (CT), magnetic resonance imaging (MRI), bronchoscopy, and surgical biopsy could be applied to the diagnosis of TE. Both drug therapy and surgical treatment were widely used to treat this disease, but no theory was used to guide the choice of treatment options.

Characterization of the metabolites of -resveratrol-3--glucoside in monkeys and dogs.

In this study, a liquid chromatography-tandem multi-stage mass spectrometry (LC/MS) method was established to characterize the metabolites of TRG in monkeys and dogs. A total of seven metabolites of TRG besides the prototype were found, which were identified as TR (M1), TRN (M2), -resveratrol-4'--glucuronide (M2'), -resveratrol-3--glucoside-4'--glucuronide (M3), -resveratrol-3--glucoside-5--glucuronide (M3'), -resveratrol-3-sulfate (M4) and -resveratrol-4'-sulfate (M4'). Additionally, the metabolic pathways of TRG in monkeys and dogs were proposed.

Hypoxia modifies the polarization of macrophages and their inflammatory microenvironment, and inhibits malignant behavior in cancer cells.

Macrophages are a heterogeneous group of phagocytes that play critical roles in inflammation, infection and tumor growth. Macrophages respond to different environmental factors and are thereby polarized into specialized functional subsets. Although hypoxia is an important environmental factor, its impact on human macrophage polarization and subsequent modification of the inflammatory microenvironment have not been fully established.
