MDSC-targeting gold nanoparticles enhance PD-1 tumor immunotherapy by inhibiting NLRP3 inflammasomes.

Myeloid-derived suppressor cells (MDSCs) play a crucial role in the immune escape mechanisms that limit the efficacy of immunotherapeutic strategies. In the tumor microenvironment, NLRP3 inflammasome-driven Interleukin-1β (IL-1β) production serves to dampen antitumor immune responses, promoting tumor growth, progression, and immunosuppression. In this study, we revealed that gold nanoparticles (Au NPs) with a size of 30 nm disrupted NLRP3 inflammasome, but not other inflammasomes, in bone marrow-derived macrophages through abrogating NLRP3-NEK7 interactions mediated by reactive oxygen species (ROS).

Enzyme/pH Dual-Responsive Engineered Nanoparticles for Improved Tumor Immuno-Chemotherapy.

Combining immune checkpoint blockade (ICB) therapy with chemotherapy can enhance the efficacy of ICB and expand its indications. However, the limited tumor specificity of chemotherapy drugs results in severe adverse reactions. Additionally, the low tissue penetration and immune-related adverse events associated with monoclonal antibodies restrict their widespread application.

DNA damage response and repair gene mutations are associated with tumor mutational burden and outcomes to platinum-based chemotherapy/immunotherapy in advanced NSCLC patients.

Background: DNA damage response and repair (DDR) genes are crucial for maintaining the integrity of the genome. This study aims to explore the correlation of DDR gene mutations with TMB, clinical characteristics, and outcomes to platinum-based chemotherapy and platinum-based chemotherapy/immunotherapy in non-small cell lung cancer (NSCLC) without EGFR and ALK alterations.

Methods: Tumor tissue from 49 patients with stage III or IV NSCLC who were without EGFR and ALK alterations were analyzed using targeted next-generation sequencing (NGS).

Methods: Tumor-specific somatic single nucleotide variants (SNVs) were identified via whole exome sequencing of tumor tissue and matched germline DNA.

Apatinib successfully administered in malignant tumour patients with severe hypotension: a case series, literature review, and considerations for treatment.

The most notable side-effect of apatinib, a novel antiangiogenic agent for the treatment of cancer, is hypertension, but there are few published studies regarding the use of apatinib to treat patients with cancer and severe hypotension. Here, the cases of three patients with tumours and severe hypotension are described: case 1, a 73-year-old male patient with lung squamous cell carcinoma who initially received radiotherapy and chemotherapy, and developed pneumonia and severe hypotension after 6 months; case 2, a 56-year-old male patient with nasopharyngeal carcinoma who was treated with chemotherapy and presented with fever and persistent hypotension; and case 3, a 77-year-old male patient with oesophageal cancer who was admitted with deglutition difficulty and severe hypotension. Apatinib was added to the treatment regimen of all three patients for antitumor therapy.

Case report: EGFR-mutant lung adenocarcinoma with the TP53 and RB1 mutations showed resistance to TKI therapy.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are a standard treatment for patients with advanced non-small-cell lung cancer (NSCLC) harboring classic EGFR mutations. However, resistance to TKIs remains a major clinical challenge. The transformation from adenocarcinoma to small-cell lung cancer (SCLC) is a rare resistance mechanism to EGFR-TKIs.

Low Infiltration of CD8+ PD-L1+ T Cells and M2 Macrophages Predicts Improved Clinical Outcomes After Immune Checkpoint Inhibitor Therapy in Non-Small Cell Lung Carcinoma.

Background: Many clinical studies have shown that patients with non-small cell lung carcinoma (NSCLC) can benefit from immune checkpoint inhibitor (ICI) therapy; however, PD-L1 and tumor mutation burden (TMB), which are recommended by the NCCN guidelines, are still insufficient in predicting the response to and prognosis of immunotherapy. Given the widespread use of ICIs, it is important to find biomarkers that can predict immunotherapy outcomes in NSCLC patients, and the exploration of additional effective biomarkers for ICI therapy is urgently needed.

Methods: A total of 33 stage II-IV NSCLC patients were included in this study.

Efficacy and safety of apatinib as third- or further-line therapy for patients with advanced NSCLC: a retrospective study.

Background: Apatinib, an oral small-molecule angiogenesis inhibitor, selectively inhibits vascular endothelial growth factor receptor VEGFR-2), which inhibits vascular endothelial growth factor (VEGF) stimulated endothelial cell migration and proliferation and decreases tumour growth and metastasis. Recently, the efficacy of multi-target angiogenic drugs has been demonstrated for many cancers, including non-small-cell lung cancer (NSCLC). The aim of this retrospective study was to evaluate the clinical efficacy of apatinib in patients with advanced NSCLC.

PI3K-AKT-mTOR pathway alterations in advanced NSCLC patients after progression on EGFR-TKI and clinical response to EGFR-TKI plus everolimus combination therapy.

Chemotherapy with or without pemetrexed as second-line regimens for advanced non-small-cell lung cancer patients who have progressed after first-line EGFR TKIs: a systematic review and meta-analysis.

Purpose: The development of acquired resistance to the first-line epidermal growth factor-tyrosine kinase inhibitor (EGFR-TKI) treatment in non-small-cell lung cancer (NSCLC) is inevitable, and most of these patients needed second-line chemotherapy.

Ruthenium Complexes Induce HepG2 Human Hepatocellular Carcinoma Cell Apoptosis and Inhibit Cell Migration and Invasion through Regulation of the Nrf2 Pathway.

Unlabelled: Ruthenium (Ru) complexes are currently the focus of substantial interest because of their potential application as chemotherapeutic agents with broad anticancer activities. This study investigated the in vitro and in vivo anticancer activities and mechanisms of two Ru complexes-2,3,7,8,12,13,17,18-Octaethyl-21H,23H-porphine Ru(II) carbonyl (Ru1) and 5,10,15,20-Tetraphenyl-21H,23H-porphine Ru(II) carbonyl (Ru2)-against human hepatocellular carcinoma (HCC) cells. These Ru complexes effectively inhibited the cellular growth of three human hepatocellular carcinoma (HCC) cells, with IC50 values ranging from 2.

To evaluate the clinical significance of pretreatment levels of plasma Epstein-Barr virus DNA (pEBV DNA) on prognoses in pediatric nasopharyngeal carcinoma (NPC) patients. Eighty-nine patients aged 21 years old or younger with nonmetastatic NPC were evaluated to determine the effect of pEBV DNA levels on progression-free survival (PFS), distant metastasis-free survival (DMFS), and overall survival (OS). Survival probabilities in patient groups that were segregated by clinical stage or pEBV DNA load (low or high) were compared.
