NTRK-rearranged spindle cell tumor with SPECC1L-NTRK3 fusion in the thoracic spine: a case report.

Neurotrophic Tyrosine Receptor Kinase (NTRK)-rearranged spindle cell tumors are a category of soft tissue tumors characterized by rearrangements of the NTRK gene family (NTRK1, NTRK2, and NTRK3), which leads to distinct molecular genetics, morphological, and immunophenotypic characteristics. The central feature of these tumors is the fusion of NTRK genes with other genes, resulting in abnormal expression and activation of tropomyosin receptor kinase proteins.In this report, we present the first documented case of an NTRK spindle cell tumor with SPECC1L-NTRK3 fusion located in the thoracic spine.

Establishment and Evaluation of a Risk Prediction Model for Pathological Escalation of Gastric Low-Grade Intraepithelial Neoplasia.

The study aims to explore the risk factors for pathological escalation after endoscopic surgery for gastric low-grade intraepithelial neoplasia (LGIN) and to establish and evaluate a risk prediction model for LGIN. A total of 120 patients diagnosed with gastric LGIN by biopsy and endoscopic submucosal dissection (ESD) between November 2020 and June 2022 were retrospectively analyzed. Gender, age, Helicobacter pylori (HP) infection, lesion size, lesion location, morphology, gastric mucosal congestion, nodules status, surface ulceration and erosion, and ME-observation of all patients were collected and divided into upgraded and non-upgraded groups according to the biopsy and ESD postoperative pathological diagnosis results.

MitoCur-1 induces ferroptosis to reverse vemurafenib resistance in melanoma through inhibition of USP14.

Melanoma is an aggressive malignant tumor with a poor prognosis. Vemurafenib (PLX4032, vem) is applied to specifically treat BRAF V600E-mutated melanoma patients. However, prolonged usage of vem makes patients resistant to the drug and finally leads to clinical failure.

Years lived with disability of cancer in China: findings from disability weights measurement with a focus on the effect of disease burden.

Disability weights are crucial for quantifying health loss associated with non-fatal outcomes and were not well assessed in different countries, especially for specific cancer. Therefore, this study aimed to identify disability weights with a focus on specific cancer in a large Chinese population. Two types of web surveys were conducted, and 254 health states, including 30 new states for specific cancer, were investigated using paired comparison methods.

Comparative study of pathological response evaluation systems after neoadjuvant chemotherapy for breast cancer: developing predictive models of multimodal ultrasound features including shear wave elastography combined with puncture pathology.

Summary: In recent years, immune checkpoint inhibitors have made a breakthrough in the systemic treatment of middle-advanced HCC, breaking the single therapeutic pattern of molecular-targeted agents.

Integrative Serum Metabolic Fingerprints Based Multi-Modal Platforms for Lung Adenocarcinoma Early Detection and Pulmonary Nodule Classification.

Identification of novel non-invasive biomarkers is critical for the early diagnosis of lung adenocarcinoma (LUAD), especially for the accurate classification of pulmonary nodule. Here, a multiplexed assay is developed on an optimized nanoparticle-based laser desorption/ionization mass spectrometry platform for the sensitive and selective detection of serum metabolic fingerprints (SMFs). Integrative SMFs based multi-modal platforms are constructed for the early detection of LUAD and the classification of pulmonary nodule.

Effect of Helicobacter Pylori on Plasma Metabolic Phenotype in Patients With Gastric Cancer.

Background: Although  (Hp) as high risk factor for gastric cancer have been investigated from human trial, present data is inadequate to explain the effect of Hp on the changes of metabolic phenotype of gastric cancer in different stages.

Purpose: Herein, plasma of human superficial gastritis (Hp negative and positive), early gastric cancer and advanced gastric cancer analyzed by UPLC-HDMS metabolomics can not only reveal metabolic phenotype changes in patients with gastric cancer of different degrees (30 Hp negative, 30 Hp positive, 20 early gastric cancer patients, and 10 advanced gastric cancer patients), but also auxiliarily diagnose gastric cancer.

Results: Combined with multivariate statistical analysis, the results represented biomarkers different from Hp negative, Hp positive, and the alterations of metabolic phenotype of gastric cancer patients.

Results of the cancer screening feasibility study in China: a multicentered randomized controlled trial of lung and colorectal cancer screening.

Background: To provide an understanding of important aspects of the participant recruitment and data collection, become aware of any potential problems, and obtain necessary information in order to design a large-scale randomized controlled trial (RCT) for lung cancer and colorectal cancer (CRC) screening in China.

Methods: This feasibility study was a multicentered, open-label, pilot randomized trial. A total of 2696 participants who were at high risk of lung cancer were recruited from three screening centers and randomly allocated to arm 1 ( = 894), annual low-dose computed tomography (LDCT) plus a baseline colonoscopy; arm 2 ( = 902), biennial LDCT plus annual fecal immunochemical test (FIT) with OC-Sensor (OC-FIT); and arm 3 ( = 900), annual Insure-FIT plus Septin 9 blood test.

Long noncoding RNA taurine-up regulated gene 1 for the prognosis of osteosarcoma: A protocol for meta-analysis and bioinformatics analysis.

Background: In recent years, a variety of long noncoding RNA (lncRNA) has been confirmed to be involved in the initiation and progression of osteosarcoma. Taurine-up regulated gene 1 (TUG1) plays an important role in the formation, invasion, and metastasis of osteosarcoma. Therefore, perhaps TUG1 is a potential biomarker for the prognosis of patients suffering from osteosarcoma.
