Non Small Cell Lung Cancer

Our study provides an example of implementation of molecular profiling in an academic pre-screening program. Further analysis will investigate treatment matching rates, drug access schemes, and their impact on treatment efficacy and survival.

KRAS mutation status did not significantly influence ICI efficacy, although a non-significant trend towards better survival was observed in KRAS-MT patients treated with first-line ICI. These findings contribute to the ongoing research in this field.

Preclinical evidence from NSCLC models showed that cell damage caused by cisplatin activates the SDF-1/CXCR4 axis, leading to the recruitment of metastasis initiating cells (MICs), a prometastatic cell subset co-expressing the stemness marker CD133 and CXCR4 (SDF-1 receptor)... CTCs may represent a novel biomarker for monitoring chemotherapy efficacy in NSCLC. An increased number of CTCs baseline and after pb-NACT, as well as after surgery represent a negative prognostic factor for survival. A higher number of CXCR4+CTCs at baseline correlated with inferior response outcomes after pb-NACT, prompting consideration for treatment intensification in pts with higher baseline levels of this CTC subtype.

METamp occurred more frequently in responders; but Teliso-V activity wasn’t restricted to these pts: most responders weren’t METamplified. Specific genomic alts beyond MET may influence clinical response. The current analysis demonstrated numeric differences between pts with identified drivers who did or didn’t respond to Teliso-V.

Blood-based LB performed by NGS is a non-invasive viable alternative tool for molecular genotyping and identifiy tumor-derived somatic alterations to increase the number of pts elegible to target therapy and guide personalized medicine.

This raises a possible nosological relationship between TSADUDT and SMARCA4/A2 deficient NSCLC. Increased understanding of the genetics, epigenetics, and mechanisms of oncogenesis in these poor prognostic tumors, which are often resistant to conventional treatment, opens a new horizon of therapy for the tumors.

The addition of ICIs to local treatment shows promising results for locally advanced patients with SD-NSCLC, and first-line ICIs are associated with improved survival in metastatic SD-NSCLC. STK11/KEAP1 mutations may be linked to reduced efficacy of immunotherapy.

TFF1 was identified as a promising therapeutic target, suggesting that targeting TFF1 could provide new treatment strategies. Further research is warranted to explore its full potential and therapeutic applicability.

Six significant transcripts, including NTF4, PTPRD-AS, ITGA11, HID1-AS1, RASGRF2-AS1, and TBX2-AS1, were identified within the ceRNA network and trans-regulation. This study brings important insights into the regulatory roles of lncRNAs in NSCLC, providing a fresh perspective on lncRNA research in tumor biology.

In conclusion, PPAP2C may be highly expressed in LUAD tissues, and could promote cell migration and invasion by activating the ERK/JNK signaling pathway and inducing EMT. These findings provide a novel potential target for the diagnosis and treatment of LUAD.

These panels remained effective across various stages and types of lung tumors, and were validated in an independent cohort of 56 patients and 72 controls. Ethnicity-related ncRNA signatures hold promise as biomarkers for tackling racial disparities in patients with lung cancer.

Euphorbia helioscopia can inhibit proliferation, invasion, and migration and induces apoptosis of NSCLC cells in vitro.

Aumolertinib combined with anlotinib can effectively inhibit NSCLC cell proliferation by downregulating the PI3K-Akt pathway, suggesting a potentially new option for NSCLC treatment.

MAGI2-AS3 enhances DDP sensitivity of NSCLC by targeted regulation of the miR-1269a/PTEN/AKT signaling axis.

Importantly, targeting NO effectively reduced CSC populations within patient-derived organoids (PDOs) during radiotherapy. This mechanism presents a promising therapeutic target to surmount radiotherapy resistance in NSCLC treatment.

Tocilizumab demonstrated significant benefits in survival and various clinical parameters, including body weight, albumin, CRP, mGPS and symptom burden in patients with NSCLC and concurrent IL-6-elevated cachexia. Given the existing unmet medical need for effective interventions for cancer cachexia, tocilizumab may be considered as a potential treatment option.

The results of our study are highly encouraging, as they revealed a significant correlation between immunohistochemical biomarkers, therapeutic regimens, and prognosis. These findings indicate that our immunohistochemical detection panel has great potential for facilitating customization of therapeutic regimens to improve patient care. The insights gained from this study could help clinicians optimize treatment protocols and ultimately enhance clinical outcomes.

Lorlatinib induced a complex dyslipidemia in our patient with elevations of both LDL-C and HDL-C. The underlying mechanism of lorlatinib-induced hyperlipidemia remains unknown and is unlikely to be secondary to nephrotic syndrome in many patients.

The diagnostic accuracy of cN1 in this study was ~40%. No history of smoking and adenocarcinoma were significant predictors for nodal upstaging. Although younger age was a significant predictor for nodal upstaging, it was a significant factor for better prognosis.

The CL immunosensor was able to accurately detect the concentration of CYFRA21-1 in serum samples, as evidenced by ELISA results. More importantly, it not only distinguished well between healthy persons and lung cancer patients (90.0% sensitivity and 90.0% specificity), but also effectively distinguished between patients with non-small cell lung cancer and small cell lung cancer (80.0% sensitivity and 86.7% specificity).

This project uncovered that the small molecular drug Ergotamine targets and inhibits the expression of KIF5A. Downregulated KIF5A can enhance the anoikis of LUAD. Our results supported the inhibition of KIF5A as an attractive therapeutic strategy for LUAD. This finding provides a new innovative pathway for the treatment of LUAD and offers a strong theoretical basis for the development of therapeutic drugs targeting KIF5A.

Moreover, TRIM47 promotes K48-linked ubiquitination, leading to the degradation of CYLD by the proteasome, thereby activating the NF-κB pathway and regulating the biological behavior of gastric cancer cells. Taken together, our study demonstrated that TRIM47 is involved in the proliferation and metastasis of gastric cancer through the CYLD/NF-κB pathway.

This study will provide evidence for the efficacy and safety of the combination of immunochemotherapy and cryoablation as a first-line treatment for advanced NSCLC. Although it has a limited sample size, the findings of this study will be used in the future to inform the design of a fully powered, 2-arm, larger-scale study.

This was associated with increased expression of DR4, DR5, Fas, and FADD and decreased expression of survivin, resulting in activation of caspase 8 and caspase 3 as well as cleavage of poly (ADP ribose) polymerase (PARP). Taken together, the results suggest that inhibition of Chk1 with PRE can enhance the anticancer activity of CPX at least partly by decreasing cell proliferation and increasing apoptosis in NSCLC cells.

This study elucidated the potential effects of Corynoxine in suppressing proliferation and metastasis in LUAD, along with investigating the underlying mechanisms. These data highlight the promise of Corynoxine as a novel therapeutic tool for the treatment of individuals diagnosed with LUAD.

GDF15 is a plasma marker that responds to the treatment of unresected LA-NSCLC with cCRT and metformin. GDF15 levels correspond with tumor volume and increased GDF15 levels predict for poor RFS and OS. These results require validation in larger clinical trial datasets.

High PD-L1 expression was more commonly found in lung adenocarcinomas with uncommon and complex EGFR mutations. Furthermore, high PD-L1 expression independently predicted poor survival. These findings warrant validation through prospective studies.

Our findings may prove valuable in the development of therapeutic and prognostic markers for LUAD. The potential clinical utility of SOD1 in LUAD requires further investigation.

Previous studies have shown that the expression of TROP-2 is related to the prognosis of patients with lung cancer and that TROP-2 expression is different across different histological types; however, research on TROP-2 and TROP-2 ADCs in patients with lung cancer is not comprehensive. The aims of this study were to review the mechanism of action and clinical efficacy of TROP-2 and related drugs in the treatment of lung cancer, to elucidate the prognostic value of TROP-2 in lung cancer, and to discuss the future prospects of TROP-2 ADCs to provide a reference for the precise treatment of lung cancer.

Here, we demonstrated that Sirtuin 5 (SIRT5), a member of the deacetylase SIRT family, functions as a desuccinylase of acetyl-CoA acetyltransferase 1 (ACAT1) and enhances the enzymatic activity of ACAT1 to activate the NRF2 pathway, inhibiting the secretion of the chemokines CCL5 and CXCL10, which are important for recruiting CD8+ T cells, thereby participating in the formation of an inhibitory TIME in EGFR-mutant LUAD. In conclusion, we propose that the combination of a SIRT5 inhibitor with ICIs therapy may be a promising therapeutic approach for patients with EGFR-mutant LUAD.

We identify that the SUMOylation inhibitor TAK-981 reduces YAP and TAZ expression, decreasing tumor burden and metastasis in a murine NSCLC model. Our study reveals an intra-tumoral division of labor, driven by differential YAP and TAZ expression, which can be effectively targeted with TAK-981 for NSCLC therapy.

The final results revealed that HE4 emerged as the most reliable biomarker, offering balanced sensitivity and specificity, with accuracy unaffected by tumor stage, making it suitable for early diagnosis. Our findings support the inclusion of HE4 in clinical guidelines for NSCLC diagnosis, alongside well-established biomarkers such as Cyfra 21-1 and CEA.

In this study, the four cell lines containing the L861Q mutation were constructed by CRISPR and the anti-tumour effects of CUDC-101 on them were investigated in vitro by various chemosensitivity methods, with afatinib serving as a positive control. The results demonstrated that CUDC-101 inhibited the proliferation and clonogenic capacity on the four cells through the ERK or AKT pathways, decreased the mitochondrial membrane potential of the cells, blocked the cell cycle and promoted apoptosis. Our findings suggest that CUDC-101 may be a promising treatment option for NSCLC patients with the EGFR exon 18 substitution mutation L861Q.

Noteworthy, CodeBreaK100 and KRYSTAL-1 clinical trials have recently demonstrated that sotorasib and adagrasib, two novel selective KRASG12C inhibitors, have clinical activity with acceptable adverse-event profile for the treatment of advanced NSCLC patients with KRASG12C mutation. In this paper, we describe the role of KRAS mutations in NSCLC focusing on the clinical and molecular characteristics which potentially identify specific subtypes of NSCLC patients based on different KRAS mutations. We also provide an overview of the main clinical trials testing novel selective KRASG12C inhibitors as well as novel potential therapeutic strategies for NSCLC patients with non-G12C KRAS mutations.

Our investigation of TACC3 revealed its potential as a promising target both for immunosuppression and docetaxel resistance in pan-cancer, especially in lung adenocarcinoma.

Here, we provide the first validation of an RNA-SBS mutational signature by decomposing novel exogenous and endogenous APOBEC3A RNA editing signatures into COSMICv3.4 RNA-SBS reference signatures. Additionally, we have identified novel RNA-SBS signatures for APOBEC1, APOBEC3B, and APOBEC3G.

Amidst this context, the present investigation delineates the synergistic potentiation of doxorubicin (DOX)-a canonical chemotherapeutic-by Ursodeoxycholic acid (UDCA), a compound with a historical pedigree in hepatobiliary medicine, now repositioned within oncological pharmacotherapy due to its dichotomous cellular modulation-affording cytoprotection to non-malignant epithelia whilst eliciting apoptotic cascades in neoplastic counterparts. The implications of this research are twofold: firstly, it offers a compelling evidence base for the clinical reevaluation of UDCA in combinatory chemotherapeutic regimens; secondly, it posits a novel mechanistic insight into the modulation of chemotherapeutic efficacy and resistance. Collectively, these insights advocate for the expedited clinical translation of UDCA-DOX synergy, potentially heralding a paradigm shift in the management of NSCLC, thereby addressing a critical lacuna in contemporary oncological therapy.

Pantoprazole (PPZ) administration at the most commonly used dose in the clinic notably increased the pondus hydrogenii (pH) of the TME, inhibited lysosomal activity, increased the membrane levels of the MSLN protein and improved the killing ability of MSLN-CAR-T cells both in vitro and in vivo. Similar results were obtained in non-small cell lung cancer (NSCLC) BMs. Hence, when administered in combination with CAR-T cells, PPZ, which increases the protein levels of target antigens, may constitute a new immunotherapeutic strategy for treating solid tumors with BMs.

Finally, a comparative analysis of PSAT1 DEGs against transcripts enriched in patient EGFR mutant lung tumors identified a gene signature that is associated with overall and relapse-free survival (RFS) and was able to distinguish low or high-risk populations for RFS in early-stage EGFR mutant NSCLC. Overall, investigating genes altered by PSAT1 loss confirmed known PSAT1-regulated cellular pathways, identified a previously unknown role in the mediation of cytoskeleton arrangement in EGFR mutant NSCLC cells and allowed for the characterization of a gene signature with putative predictive potential for RFS in early-stage disease.
