Cancers, Vol. 12, Pages 1475: Non-Small-Cell Lung Cancer Signaling Pathways, Metabolism, and PD-1/PD-L1 Antibodies Cancers doi: 10.3390/cancers12061475 Authors: Mariacarmela Santarpia Andrés Aguilar Imane Chaib Andrés Felipe Cardona Sara Fancelli Fernando Laguia Jillian Wilhelmina Paulina Bracht Peng Cao Miguel Angel Molina-Vila Niki Karachaliou Rafael Rosell Treatment of advanced (metastatic) non-small-cell lung cancer (NSCLC) is currently mainly based on immunotherapy with antibodies against PD-1 or PD-L1, alone, or in combination with chemotherapy. In locally advanced NSCLC and in early resected stages, immunotherapy is also employed. Tumor PD-L1 expression by immunohistochemistry is considered the standard practice. Response rate is low, with median progression free survival very short in the vast majority of studies reported. Herein, numerous biological facets of NSCLC are described involving driver genetic lesions, mutations ad fusions, PD-L1 glycosylation, ferroptosis and metabolic rewiring in NSCLC and lung adenocarcinoma (LUAD). Novel concepts, such as immune-transmitters and the effect of neurotransmitters in immune evasion and tumor growth, the nascent relevance of necroptosis and pyroptosis, possible new biomarkers, such as gasdermin D and gasdermin E, the conundrum of K-Ras mutations in LUADs, with the growing recognition of liver kinase B1 (LKB1) and metabolic pathways, including others, are also commented. The review se...

Lung cancer is the leading cause of cancer-related deaths worldwide. Non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancer is divided mainly into lung squamous cell carcinoma (LUSC), lung adenocarcinoma (LUAD), and large cell carcinoma (LCC) [1]. Although great progress has been made in targeted treatment and immunotherapy, Platinum-based combination chemotherapy is still the standard chemotherapy treatment for wild type lung adenocarcinoma, and cisplatin (DDP) is widely used [2,3].

Background: Serum tumor markers carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), cytokeratin 19 fragment (CYFRA21-1) and squamous-cell carcinoma-related antigen (SCC-Ag) are routinely used for monitoring the response to chemotherapy or targeted therapy in advanced-stage non-small cell lung cancer (NSCLC), however their role in immunotherapy remains unclear. The aim of this study was to investigate whether dynamics of these serum markers were associated with the efficacy and prognosis of Chinese late-stage NSCLC patients treated with programmed cell death-1/programmed cell death ligand-1 (PD-1/PD-L1) inhibitors.M...

ConclusionOur findings confirm pericardial effusion as a relatively frequent side effect of immunotherapy in NSCLC. Clinicians should be aware of this specific toxicity in patients with metastatic NSCLC receiving immunotherapy and refer to a cardiologist for a multidisciplinary approach.

Conclusion: Bronchoscopic re-biopsy for progressive lung cancer is feasible and safe. Histological change can be detected in a considerable number of patients, which is potentially valuable information for guidance of subsequent treatment.

This case report highlights that multidisciplinary treatment planning is critical for stage IIIb –IV non‐small cell lung cancer (NSCLC) patients in the era of highly effective treatments, including chemotherapy, molecular targeted therapy, and immunotherapy, which may demonstrate treatment‐free remission (TFR) even in highly selected advanced lung cancer patients with poly‐metastases, a nd we need more information about the association between each genetic alteration and the significance of salvage surgery. The prognosis of stage IVb non ‐small cell lung cancer (NSCLC) patients with multiple distant metastase...

Conclusions: ICI induced regression in some tumors with actionable driver alterations, but clinical activity was lower compared with theKRAS group and the lack of response in the ALK group was notable. Patients with actionable tumor alterations should receive targeted therapies and chemotherapy before considering immunotherapy as a single agent.

Lei Shang1,2 and Minjie Wei1* 1School of Pharmacy, China Medical University, Shenyang, China 2Shenyang Medical College, Shenyang, China The protein lysine methyltransferase SMYD2 has recently emerged as a new enzyme modulate gene transcription or signaling pathways, and involved into tumor progression. However, the role of SMYD2 in drug resistant is still not known. Here, we found that inhibition of SMYD2 by specific inhibitor could enhance the cell sensitivity to cisplatin (CDDP), but not paclitaxel, NVB, and VCR in non-small cell lung cancer (NSCLC). Further study showed that SMYD2 and its substrates were overex...
