Reduction in surgical scope after neoadjuvant chemotherapy and immunotherapy for non-small cell lung cancer.

Neoadjuvant chemotherapy combined with immunotherapy is a crucial treatment modality for patients with resectable non-small cell lung cancer (NSCLC). Whilst neoadjuvant chemoimmunotherapy enables tumor downstaging, the impact of reducing the surgical scope (such as from pneumonectomy to lobectomy) on safety and efficacy remains unvalidated in real-world settings. The present study aimed to use real-world data to compare the safety and long-term efficacy of several surgical methods following neoadjuvant treatment.

Targeted tumor cell-intrinsic CTRP6 biomimetic codelivery synergistically amplifies ferroptosis and immune activation to boost anti-PD-L1 immunotherapy efficacy in lung cancer.

Background: Lung adenocarcinoma (LUAD) is a refractory tumor with high incidence, high mortality, and easy development of drug resistance. Represented by PD-L1, the rise of immunotherapy and multidrug combinations offers a reliable approach to treating LUAD. However, there are still some patients with immunoresistance or insensitivity, and new combination therapies are still needed.

Efficacy and safety of perioperative sintilimab plus platinum-based chemotherapy for potentially resectable stage IIIB non-small cell lung cancer (periSCOPE): an open-label, single-arm, phase II trial.

Background: The absolute overall survival (OS) improvement with preoperative chemotherapy or chemoradiotherapy in locally advanced non-small cell lung cancer (NSCLC) patients is controversial and unsatisfactory. We designed this trial to explore the efficacy and safety of perioperative sintilimab plus platinum-based chemotherapy for potentially resectable stage IIIB NSCLC to facilitate further optimization of this therapeutic strategy.

Methods: Patients diagnosed with stage IIIB NSCLC through invasive staging approaches and/or PET/CT scans and evaluated as having a high probability of radical resection of the primary lesion and metastatic lymph nodes with clear pathological margins by a multidisciplinary team were enrolled in this open-label, single-arm, phase II trial at a single centre in China.

Multi-branch attention Raman network and surface-enhanced Raman spectroscopy for the classification of neurological disorders.

Surface-enhanced Raman spectroscopy (SERS), a rapid, low-cost, non-invasive, ultrasensitive, and label-free technique, has been widely used in-situ and ex-situ biomedical diagnostics questions. However, analyzing and interpreting the untargeted spectral data remains challenging due to the difficulty of designing an optimal data pre-processing and modelling procedure. In this paper, we propose a Multi-branch Attention Raman Network (MBA-RamanNet) with a multi-branch attention module, including the convolutional block attention module (CBAM) branch, deep convolution module (DCM) branch, and branch weights, to extract more global and local information of characteristic Raman peaks which are more distinctive for classification tasks.

Replication-driven HBV cccDNA loss in chimeric mice with humanized livers.

Hepatitis B virus (HBV) infection is largely noncytopathic and requires the establishment of covalently closed circular DNA (cccDNA), which is considered stable in the nuclei of infected cells. Although challenging, approaches to directly target cccDNA molecules or kill infected cells are recommended to eliminate cccDNA. Herein, cccDNA levels were investigated in HBV-infected chimeric mice with humanized livers.

CTRP6 protects against ferroptosis to drive lung cancer progression and metastasis by destabilizing SOCS2 and augmenting the xCT/GPX4 pathway.

Deep CNN Model Using CT Radiomics Feature Mapping Recognizes EGFR Gene Mutation Status of Lung Adenocarcinoma.

To recognize the epidermal growth factor receptor (EGFR) gene mutation status in lung adenocarcinoma (LADC) has become a prerequisite of deciding whether EGFR-tyrosine kinase inhibitor (EGFR-TKI) medicine can be used. Polymerase chain reaction assay or gene sequencing is for measuring EGFR status, however, the tissue samples by surgery or biopsy are required. We propose to develop deep learning models to recognize EGFR status by using radiomics features extracted from non-invasive CT images.
