Weekly albumin-bound paclitaxel/cisplatin versus gemcitabine/cisplatin as first-line therapy for patients with advanced non-small-cell lung cancer:A phase II open-label clinical study

Objective: The aim of this trial was to compare both the efficacy and the safety of a weekly nanoparticle albumin-bound paclitaxel(nab-paclitaxel) plus cisplatin vs. gemcitabine plus cisplatin in patients with advanced non-small-cell lung cancer(NSCLC).Methods: A total of 84 participants received either 100 mg/m^2 nab-paclitaxel each week on d 1, 8 and 15 of a 28 day cycle, as well as cisplatin 75 mg/m^2 on d 1 every three weeks(nab-TP arm); or gemcitabine 1,000 mg/m^2 on d 1 and 8, plus cisplatin 75 mg/m^2 on d 1 every three weeks(GP arm). The primary end point was progression-free survival(PFS). The secondary end points were overall response rate(ORR) and overall survival(OS).Results: According to our analysis, the median PFS was 4.8 months for the nab-TP arm vs. 5.2 months for the GP arm(P=0.55). Analysis showed the median OS was 14.6 months for participants who were in the nab-TP arm vs. 15.1 months for those in the GP arm(P=0.94). Besides, nab-TP showed OS advantages over GP in patients harboring epidermal growth factor receptor(EGFR) mutation(26.7 vs. 15.3 months, P=0.046) and patients with a performance status of 0(23.5 vs. 14.7 months, P=0.020). It was found that incidences of drug-related grade 3 or 4 toxicities were comparable between the two treatment arms.Conclusions: Therefore, it can be seen that weekly nab-TP treatment has a similar efficacy and tolerability to GP treatment for patients who are undergoing their first-line treatment for NSCLC. It could be that survival differences among platinum doublets in the context of both EGFR mutation and performance status have the potential to be the basis for our further clinical trials.

Sequential therapy according to distinct disease progression patterns in advanced ALK-positive non-small-cell lung cancer after crizotinib treatment

Objective: Crizotinib is recommended as the first-line therapy for advanced anaplastic lymphoma kinase(ALK)-positive non-small-cell lung cancer(NSCLC). Despite its initial efficacy, patients ultimately acquire resistance to crizotinib within 1 year. In such patients, the optimal sequential therapy after crizotinib treatment remains unknown. This study explored which sequential therapy option confers the greatest benefit.Methods: A total of 138 patients with advanced ALK-positive NSCLC resistant to crizotinib were studied. Based on patterns of disease progression of metastases, patients were divided into 3 groups: brain progression, non-liver progression, and liver progression. Sequential therapies included crizotinib continuation plus local therapy, nextgeneration ALK inhibitors(ALKi's), and chemotherapy. The primary endpoint was overall survival(OS) from the time of crizotinib resistance to death or last follow-up.Results: The 138 patients included 64 cases with progression in brain, 57 cases in non-liver sites and 17 cases in liver. A significant difference in OS was observed among the distinct progression pattern(median OS, 25.4 months in brain, 15.8 months in non-liver, and 10.8 months in liver, respectively, P=0.020). The difference in OS among sequential therapies was statistically significant in the non-liver progression group(median OS, 27.6 months with next-generation ALKi's, 13.3 months with crizotinib continuation, and 10.8 months with chemotherapy,respectively, P=0.019). However, crizotinib continuation plus local therapy seems to provide non-inferior median OS compared with next-generation ALKi's for patients with brain progression(median OS, 28.9 months vs.32.8 months, P=0.204). And no significant differences in OS were found in patients with progression in liver(P=0.061).Conclusions: Crizotinib continuation together with local therapy might be a feasible strategy for patients with progression in brain beyond crizotinib resistance, as well as next-generation ALKi's. Next-generation ALKi's tended to provide a survival benefit in patients with non-liver progression.

Advances in adjuvant systemic therapy for non-small-cell lung cancer

Non-small-cell lung cancer remains a leading cause of death around the world. For most cases, the only chance of cure comes from resection for localised disease, however relapse rates remain high following surgery. Data has emerged over recent years regarding the utility of adjuvant chemotherapy for improving disease-free and overall survival of patients following curative resection. This paper reviews the clinical trials that have been conducted in this area along with the studies integrating radiation therapy in the adjuvant setting. The role of prognostic gene signatures are reviewed as well as ongoing clinical trials including those incorporating biological or targeted therapies.

Immediate Versus Delayed Treatment with EGFR Tyrosine Kinase Inhibitors after First-line Therapy in Advanced Non-small-cell Lung Cancer

Objective： To analyze the outcomes of patients who received TKI immediately after the first-line without progression as maintenance treatment （immediate group） vs. those received delayed treatment upon disease progression as second-line therapy （delayed group）. Methods： The study included 159 no-small-cell lung cancer （NSCLC） patients who received gefitinib or erlotinib as maintenance treatment in the immediate group （85 patients） or as second-line therapy in the delayed group （74 patients）. The primary end point was progression-free survival （PFS）. EGFR mutation status was detected using denaturing high-performance liquid chromatography （DHPLC）. Results： PFS was 17.3 and 16.4 months in the immediate and delayed groups, respectively （hazard ratio [HR], 0.99; 95% Confidence Interval [CI]： 0.69-1.42; P=0.947）. In a subgroup analysis that included only patients with EGFR mutation, however, PFS was significantly longer in the immediate group than in the delayed group （HR, 0.48; 95% CI： 0.27-0.85; P=0.012）. In patients with wild type EGFR, the risk for disease progression was comparable between the two groups （HR, 1.23; 95% CI： 0.61-2.51; P=0.564）. No significant difference was demonstrated between the immediate and delayed group in terms of the overall survival （OS） （26.1 months vs. 21.6 months, respectively; HR=0.53; 95% CI： 0.27 to 1.06; P=0.072）. There was also no difference in the incidence of adverse events between the two groups. Conclusions： EGFR TKI maintenance improves PFS in patients with EGFR mutation. Prospectively designed clinical studies that compare TKI immediate vs. delayed treatment after first-line chemotherapy upon disease progression are needed.

Therapy for non-small-cell lung cancer patients with brain metastasis

Brain metastasis is a major cause of poor prognosis and high mortality for non-small cell lung cancer patients. The prognosis of non-small-cell lung cancer(NSCLC) patients with brain metastasis is generally poor and more effective treatment is required to improve their prognosis. Whole-brain radiotherapy, surgery, stereotactic radiosurgery, chemotherapy and targeted therapy are the main treatment for brain metastasis. This review focuses on the five therapeutic strategy and in particular, on targeted therapy.

Leveraging diverse cell-death patterns to predict the clinical outcome of immune checkpoint therapy in lung adenocarcinoma:Based on muti-omics analysis and vitro assay

Advanced LUAD shows limited response to treatment including immune therapy.With the development of sequencing omics,it is urgent to combine high-throughput multi-omics data to identify new immune checkpoint therapeutic response markers.Using GSE72094(n=386)and GSE31210(n=226)gene expression profile data in the GEO database,we identified genes associated with lung adenocarcinoma(LUAD)death using tools such as“edgeR”and“maftools”and visualized the characteristics of these genes using the“circlize”R package.We constructed a prognostic model based on death-related genes and optimized the model using LASSO-Cox regression methods.By calculating the cell death index(CDI)of each individual,we divided LUAD patients into high and low CDI groups and examined the relationship between CDI and overall survival time by principal component analysis(PCA)and Kaplan-Meier analysis.We also used the“ConsensusClusterPlus”tool for unsupervised clustering of LUAD subtypes based on model genes.In addition,we collected data on the expression of immunomodulatory genes and model genes for each cohort and performed tumor microenvironment analyses.We also used the TIDE algorithm to predict immunotherapy responses in the CDI cohort.Finally,we studied the effect of PRKCD on the proliferation and migration of LUAD cells through cell culture experiments.The study utilized the TCGA-LUAD cohort(n=493)and identified 2,901 genes that are differentially expressed in patients with LUAD.Through KEGG and GO enrichment analysis,these genes were found to be involved in a wide range of biological pathways.The study also used univariate Cox regression models and LASSO regression analyses to identify 17 candidate genes that were best associated with mortality prognostic risk scores.By comparing the overall survival(OS)outcomes of patients with different CDI values,it was found that increased CDI levels were significantly associated with lower OS rates.In addition,the study used unsupervised cluster analysis to divide 115 LUAD patients into two distinct clusters with significant differences in OS timing.Finally,a prognostic indicator called CDI was established and its feasibility as an independent prognostic indicator was evaluated by Cox proportional risk regression analysis.The immunotherapy efficacy was more sensitive in the group with high expression of programmed cell death models.Relationship between programmed cell death(PCD)signature models and drug reactivity.After evaluating the median inhibitory concentration(IC50)of various drugs in LUAD samples,statistically significant differences in IC50 values were found in cohorts with high and low CDI status.Specifically,Gefitinib and Lapatinib had higher IC50 values in the high-CDI cohort,while Olaparib,Oxaliplatin,SB216763,and Axitinib had lower values.These results suggest that individuals with high CDI levels are sensitive to tyrosine kinase inhibitors and may be resistant to conventional chemotherapy.Therefore,this study constructed a gene model that can evaluate patient immunotherapy by using programmed cell death-related genes based on muti-omics.The CDI index composed of these programmed cell death-related genes reveals the heterogeneity of lung adenocarcinoma tumors and serves as a prognostic indicator for patients.

Unresectable stage Ⅲ non-small-cell lung cancer: Have we made any progress?

Lung cancer is responsible for the most cancer deaths worldwide with an incidence that is still rising. One third of patients have unresectable stage ⅢA or stage ⅢB disease. The standard of care for locally advanceddisease in patients with good performance status consists of combined modality therapy in particular concurrent chemoradiotherapy. But despite a lot of efforts done in the past, local control and survival of patients with unresectable stage Ⅲ non-small-cell lung cancer(NSCLC) remains poor. Improving outcomes for patients with unresectable stage Ⅲ NSCLC has therefore been an area of ongoing research. Research has focused on improving systemic therapy, improving radiation therapy or adding a maintenance therapy to consolidate the initial therapy. Also implementation of newer targeted therapies and immunotherapy has been investigated as well as the option of prophylactic cranial irradiation. This article reviews the latest literature on improving local control and preventing distant metastases. It seems that we have reached a plateau with conventional chemotherapy. Radiotherapy dose escalation did not improve outcome although increasing radiation dose-intensity with new radiotherapy techniques and the use of newer agents, e.g., immunotherapy might be promising. In the future well-designed clinical trials are necessary to prove those promising results.

Molecular Mechanisms Contributing to Resistance to Tyrosine Kinase-Targeted Therapy for Non-Small Cell Lung Cancer

One of the most important pathways in non-small cell lung cancer(NSCLC) is the epidermal growth factor receptor(EGFR) pathway. This pathway affects several crucial processes in tumor development and progression,including tumor cell proliferation,apoptosis regulation,angiogenesis,and metastatic invasion.Targeting EGFR is currently being intensely explored.We are witnessing the development of a number of potential molecular-inhibiting treatments for application in clinical oncology.In the last decade,the tyrosine kinase(TK) domain of the EGFR was identified in NSCLC patients,and it has responded very well with a dramatic clinical improvement to TK inhibitors such are gefitinib and erlotinib.Unfortunately,there were primary and/or secondary resistance to these treatments,as shown by clinical trials.Subsequent molecular biology studies provided some explanations for the drug resistance phenomenon.The molecular mechanisms of resistance need to be clarified.An in-depth understanding of these targeted-therapy resistance may help us explore new strategies for overcoming or reversing the resistance to these inhibitors for the future of NSCLC treatment.

Gene Polymorphisms and Chemotherapy in Non-small Cell Lung Cancer

The phamacogenetics is being used to predict whether the selected chemotherapy will be really effective and tolerable to the patient. Irinotecan,oxidized by CYP3A4 to produce inactive compounds,is used for treatment of various cancers including advanced non small cell lung cancer (NSCLC) patients. CYP3A4*16B polymorphism was associated with decreased metabolism of irrinotecan. Irinotecan is also metabolized by carboxylesterase to its principal active metabolite,SN-38,which is subsequently glucuronidated by UGT1As to form the inactive compound SN-38G. UGT1A1*28 and UGT1A1*6 polymorphisms were useful for predicting severe toxicity with NSCLC patients treated with irinotecan-based chemotherapy. Platinum-based compounds (cisplatin,carboplatin) are being used in combination with new cytotoxic drugs such as gemcitabine,paclitaxel,docetaxel,or vinorelbine in the treatment of advanced NSCLC. Cisplatin activity is mediated through the formation of cisplatin-DNA adducts. Gene polymorphisms of DNA repair factors are therefore obvious candidates for determinants of repair capacity and chemotherapy efficacy. ERCC1,XRCC1 and XRCC3 gene polymorphisms were a useful marker for predicting better survival in advanced NSCLC patients treated with platinum-based chemotherapy. XPA and XPD polymorphisms significantly increased response to platinum-based chemotherapy. These DNA repair gene polymorphisms were useful as a predictor of clinical outcome to the platinum-based chemotherapy. EGFR kinase inhibitors induce dramatic clinical responses in NSCLC patients with advanced disease. EGFR gene polymorphism in intron 1 contains a polymorphic single sequence dinucleotide repeat (CA-SSR) showed a statistically significant correlation with the gefitinib response and was appeared to be a useful predictive marker of the development of clinical outcome containing skin rashes with gefitinib treatment. The other polymorphisms of EGFR were also associated with increased EGFR promoter activity. EGFR gene mutations and polymorphisms were also associated with EGFR kinase inhibitors response and toxicity.

The Therapeutic Effects of the Radiotherapy Plus TCM Treatment Observed in Senile Non-Parvicellular Lung Cancer Patients at the Late Stage

47 senile non-parvicellular lung cancer patients at stage Ⅲ or Ⅳ were randomly divided into a treatment group (26 cases) treated by radiotherapy plus traditional Chinese medicine (TCM) and a control group (21 cases) treated only by radiotherapy for observation of the therapeutic effects.The patients in the treatment group orally took Chinese medicine during and after the radiotherapy.There was no obvious difference in short-term therapeutic effects between the two groups,but the long-term curative effects in the treatment group was obviously superior to that in the control group (P<0.05 or P<0.01).Conclusion:radiotherapy plus TCM can prolong the survival period for senile non-parvicellular lung cancer patients.

Missing the Target?—Targeted Therapy in Small Cell Lung Cancer

Pretreatment levels of circulating endothelial cells on efficacy of first-line therapy in patients with advanced non-small cell lung cancer

Background:Elevated levels of circulating endothelial cells might reflect significant vascular damage and dysfunction.Recent studies have shown that circulating endothelial cells levels are related to therapeutic responses of tumors,and thus,could be used as an indicator to predict the efficacy of tumor treatments.The purpose of this study was to investigate the correlation and impact of endothelial cells with and on the efficacy of first-line therapy(platinum-based or tyrosine kinase inhibitor drugs treatments)for advanced non-small-cell lung cancer.Methods:We analyzed 45 inpatients who met the inclusion criteria of diagnosis with inoperable non-small-cell lung cancer stages III and IV,in the People’s Hospital of Guangxi Zhuang Autonomous Region from January 2019 to January 2020.The flow cytometry technique was adopted to detect pretreatment levels of circulating endothelial cells in peripheral blood of patients with advanced non-small-cell lung cancer.The pretreatment peripheral blood was collected to analyze the relations of circulating endothelial cells with different clinical characteristics and efficacy.Results:The level of pretreatment circulating endothelial cells was significantly correlated with the efficacy of treatment(P<0.05)but irrelevant to the patient’s physical conditions,pathological type,tumor stage,and pretreatment serum carcinoembryonic antigen(P>0.05).The comparison between the groups of response(complete response+partial response)and nonresponse(stable disease+progressive disease)showed a significant difference in circulating endothelial cells count.Compared with low levels of circulating endothelial cells,a high level of circulating endothelial cells led to a poor efficacy(P<0.05).Conclusion:The level of pretreatment circulating endothelial cells significantly correlated with the efficiency of first-line therapy for non-small-cell lung cancer.Compared with low level of circulating endothelial cells,high level of circulating endothelial cells lead to poor efficacy.Therefore,circulating endothelial cell is indeed an effective indicator for predicting the efficacy of first-line therapy for advanced non-small-cell lung cancer.

Role of MetallothioneinlH in Cisplatin Resistance of Non-Small Cell Lung Cancer Cells

Objective： Despite platinum-based adjuvant chemotherapy has improved greatly patients＇ outcomes, drug resistance poses a major impediment to the successful use of such an effective agent. Metallothioneins（MTs） are known to play putative roles in cancer cell proliferation, apoptosis, differentiation, drug resistance and prognosis. The present studiy was to investigte the role of metallethioeinlH（MTIH） in cisplatin resistance of human non-small cell lung cancer（NSCLC） cell lines in vitro or its possible molecular mechanisms. Methods： MTIH mRNA expression in A549 and A549/DDP cells was detected by RT-PCR. A recombinant eukaryotic expression plasmid pcDNA3.1（-）-MT1H was constructed and transfected into A549 cells which express no MTIH. MT1H siRNA was transfected into A549/DDP cells which express MTIH highly. MTIH expression was detected by RT-PCR and Immunoblot. The chemosensitivity to cisplatin was assessed by MTT assay. Apoptosis rate was determined by Tunel and FCM. Bcl-2 and Bax were determined by immunohistochemistry. Results： MT1H mRNA was expressed in A549/DDP but not in A549. After transfection of MT1H, MT1H expression was enhanced and the chemosensitivity to cisplatin was decreased in A549 cells. Inversely, after transfection of MT1H siRNA, MT1H expression was decreased and the chemosensitivity to cisplatin was increased in A549/DDP. The apoptosis rate induced by cisplatin was increased and Bcl-2 was down-regulated but Bax showed little change in A549/DDP cells interferred with MT1H siRNA. Conclusion： MT1H overexpression can promote drug resistance in A549 cells . Down-regulation of MTIH interfered with siRNA can effectively reverses the drug resistance in A549/DDP cells by down-regulating the expression of Bcl-2 and increasing cisplatin induced apoptosis. SiRNA targeting MT1H combined with chemotherapy may be a very promising strategy for treatment of lung cancer.
