Lung cancer is the most prevalent and fatal cancer in China and even around the world, and many patients are found in the late stage of lung cancer. For the treatment of advanced lung cancer, in addition to traditional chemotherapy modalities, many emerging treatments are increasingly significant, such as immunotherapy, anti-angiogenic therapy, and targeted therapy. An increasing number of studies have now shown that anti-angiogenic therapy improves the immune microenvironment by enhancing tumor immunity through normalization of tumor vessels. Immunization combined with anti-angiogenic therapy can exert synergistic effects and improve the prognosis of patients. This article summarizes the extent of benefit, current clinical study data, and future prospects of immunotherapy combined with anti-angiogenic agents in the treatment of advanced NSCLC. 展开更多

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. 展开更多

The global incidence of lung cancer is marked by a considerably elevated mortality rate.MicroRNAs(miRNAs)exert pivotal influence in the intricate orchestration of gene regulation,and their dysregulation can precipitate dire consequences,notably cancer.Within this context,miRNAs encapsulated in exosomes manifest a diversified impact on the landscape of lung cancer,wherein their actions may either foster angiogenesis,cell proliferation,and metastasis,or counteract these processes.This comprehensive review article discerns potential targets for the prospective development of therapeutic agents tailored for lung cancer.Tumor-suppressive miRNAs,such as miR-204,miR-192,miR-30a,miR-34a,miR-34b,miR-203,and miR-212,exhibit heightened expression and demonstrate the capacity to inhibit cellular proliferation and invasiveness.Conversely,the deleterious effects of tumor-promoting miRNAs like miR-21,miR-106a,miR-155,miR-205,and miR-210 can be attenuated through the application of their respective inhibitors.Distinct miRNAs selectively target various oncogenes,including NUAK Family Kinase 1(NUAK1),Snail Family Transcriptional Repressor 1(Snai1),Astrocyte elevated gene-1(AEG-1),Vimentin,Proliferation and apoptosis adaptor protein 15(PEA-15/PED),Hypoxia-inducible factor 1-alpha(HIF1),as well as tumor suppressor genes such as phosphatase and tensin homolog(PTEN),Suppressor of cytokine signaling 1(SOCS1),Tumor protein P53 binding protein 1(TP53BP1),and PH Domain and Leucine Rich Repeat Protein Phosphatase 2(PHLP22).This investigative approach proves invaluable in elucidating the specific miRNAs implicated in the deregulation of crucial genes pivotal to the pathogenesis of cancer. 展开更多

Objective The combination of stereotactic body radiation therapy(SBRT)and immune checkpoint inhibitors(ICIs)is actively being explored in advanced non-small-cell lung cancer(NSCLC)patients.However,little is known about the optimal fractionation and radiotherapy target lesions in this scenario.This study investigated the effect of SBRT on diverse organ lesions and radiotherapy dose fractionation regimens on the prognosis of advanced NSCLC patients receiving ICIs.Methods The medical records of advanced NSCLC patients consecutively treated with ICIs and SBRT were retrospectively reviewed at our institution from Dec.2015 to Sep.2021.Patients were grouped according to radiation sites.Progression-free survival(PFS)and overall survival(OS)were recorded using the Kaplan-Meier method and compared between different treatment groups using the log-rank(Mantel-Cox)test.Results A total of 124 advanced NSCLC patients receiving ICIs combined with SBRT were identified in this study.Radiation sites included lung lesions(lung group,n=43),bone metastases(bone group,n=24),and brain metastases(brain group,n=57).Compared with the brain group,the mean PFS(mPFS)in the lung group was significantly prolonged by 13.3 months(8.5 months vs.21.8 months,HR=0.51,95%CI:0.28–0.92,P=0.0195),and that in the bone group prolonged by 9.5 months with a 43%reduction in the risk of disease progression(8.5 months vs.18.0 months,HR=0.57,95%CI:0.29–1.13,P=0.1095).The mPFS in the lung group was prolonged by 3.8 months as compared with that in the bone group.The mean OS(mOS)in the lung and bone groups was longer than that of the brain group,and the risk of death decreased by up to 60%in the lung and bone groups as compared with that of the brain group.When SBRT was concurrently given with ICIs,the mPFS in the lung and brain groups were significantly longer than that of the bone group(29.6 months vs.16.5 months vs.12.1 months).When SBRT with 8–12 Gy per fraction was combined with ICIs,the mPFS in the lung group was significantly prolonged as compared with that of the bone and brain groups(25.4 months vs.15.2 months vs.12.0 months).Among patients receiving SBRT on lung lesions and brain metastases,the mPFS in the concurrent group was longer than that of the SBRT→ICIs group(29.6 months vs.11.4 months,P=0.0003 and 12.1 months vs.8.9 months,P=0.2559).Among patients receiving SBRT with<8 Gy and 8–12 Gy per fraction,the mPFS in the concurrent group was also longer than that of the SBRT→ICIs group(20.1 months vs.5.3 months,P=0.0033 and 24.0 months vs.13.4 months,P=0.1311).The disease control rates of the lung,bone,and brain groups were 90.7%,83.3%,and 70.1%,respectively.Conclusion The study demonstrated that the addition of SBRT on lung lesions versus bone and brain metastases to ICIs improved the prognosis in advanced NSCLC patients.This improvement was related to the sequence of radiotherapy combined with ICIs and the radiotherapy fractionation regimens.Dose fractionation regimens of 8–12 Gy per fraction and lung lesions as radiotherapy targets might be the appropriate choice for advanced NSCLC patients receiving ICIs combined with SBRT. 展开更多

Globally,cancer cases and mortality have recently escalated and have attracted global concern.The clinical diagnosis and manifestation of cancer can result in significant mental health issues like depression and anxiety disorders.The tendency of people with cancer to suffer from psychological disorders such as anxiety and depression is usually high.A significant number of deaths related to cancer may likely not be from the killer disease but from psychological disorders associated with the illness.The utilization of music as a remedial approach to healing mental disorders cannot be overstated.Thus,identifying the impacts of music therapy in dealing with depression and anxiety disorders among people with cancer is relevant,as the majority of methods used in treating cancer have some side effects which may trigger psychological disorders in cancer patients.Ultimately,this study explored the significance of music therapy in treating depression and anxiety disorders among people with cancer.To achieve the aim of this study,the authors employed a narrative literature review to investigate the significance of music therapy in addressing depression and anxiety disorders among people with cancer.The type of literature review employed in this study is to provide an understanding of the selected research papers.The review found that music therapy significantly reduces depression and anxiety disorders among breast cancer,lung cancer,prostate cancer,and colorectal cancer patients.It is needful for healthcare providers to incorporate music therapy interventions while treating people with cancer.This will help reduce cancer deaths resulting from psychological disorders rather than the killer disease,cancer.However,the standardized procedures and evaluation criteria for applying music-based intervention strategies in oncology medicine still need to be further established and improved. 展开更多

BACKGROUND The development of anaplastic lymphoma kinase(ALK)-tyrosine kinase inhibitors(TKIs)has remarkably improved the prognosis of patients with ALK-positive advanced non-small cell lung cancer(NSCLC).Alectinib,the second-generation ALK-TKI,has been approved as first-line treatment for advanced or metastatic NSCLC patients with ALK rearrangement.Neoadjuvant therapy can achieve tumor downstaging and eradicate occult lesions in patients with potentially resectable disease.Whether neoadjuvant alectinib can be a conversion therapy in ALK-positive advanced NSCLC patients remains unclear.CASE SUMMARY A 41-year-old man was pathologically diagnosed with locally advanced ALKpositive stage IIIB NSCLC.Alectinib was prescribed to induce tumor downstaging and facilitate the subsequent surgical resection.The tumor was successfully downstaged and pathological complete response was achieved.Left upper lobectomy with mediastinal lymphadenectomy was performed after tumor downstaging.The patient has continued to receive alectinib as adjuvant therapy during postoperative follow-up with a recurrence-free survival of 29 mo as of writing this report.CONCLUSION This case sheds light on the feasibility and safety of alectinib as a neoadjuvant treatment for stage IIIB NSCLC patients with ALK rearrangement.Its efficacy needs to be validated in prospective clinical trials. 展开更多

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. 展开更多

Stereotactic body radiation therapy(SBRT) is the treatment of choice for medically inoperable patients with early stage non-small cell lung cancer(NSCLC). A literature search primarily based on PubMed electronic databases was completed in July 2018. Inclusion and exclusion criteria were determined prior to the search, and only prospective clinical trials were included. Nineteen trials from 2005 to 2018 met the inclusion criteria, reporting the outcomes of 1434 patients with central and peripheral early stage NSCLC. Patient eligibility,prescription dose and delivery, and follow up duration varied widely. Threeyears overall survival ranged from 43% to 95% with loco-regional control of up to 98% at 3 years. Up to 33% of patients failed distantly after SBRT at 3 years. SBRT was generally well tolerated with 10%-30% grade 3-4 toxicities and a few treatment-related deaths. No differences in outcomes were observed between conventionally fractionated radiation therapy and SBRT, central and peripheral lung tumors, or inoperable and operable patients. SBRT remains a reasonable treatment option for medically inoperable and select operable patients with early stage NSCLC. SBRT has shown excellent local and regional control with toxicity rates equivalent to surgery. Decreasing fractionation schedules have been consistently shown to be both safe and effective. Distant failure is common, and chemotherapy may be considered for select patients. However, the survival benefit of additional interventions, such as chemotherapy, for early stage NSCLC treated with SBRT remains unclear. 展开更多

The last decade has witnessed the development of oncogene-directed targeted therapies that have significantly changed the treatment of non-small-cell lung cancer(NSCLC). In this paper we review the data demonstrating efficacy of gefitinib, erlotinib, and afatinib, which target the epidermal growth factor receptor(EGFR), and crizotinib which targets anaplastic lymphoma kinase(ALK). We discuss the challenge of acquired resistance to these small-molecular tyrosine kinase inhibitors and review promising agents which may overcome resistance, including the EGFR T790 Mtargeted agents CO-1686 and AZD9291, and the ALKtargeted agents ceritinib(LDK378), AP26113, alectinib(CH/RO5424802), and others. Emerging therapies directed against other driver oncogenes in NSCLC including ROS1, HER2, and BRAF are covered as well. The identification of specific molecular targets in a significant fraction of NSCLC has led to the personalized deployment of many effective targeted therapies, with more to come. 展开更多

Lung cancer represents the leading cause of cancer mortality worldwide. Despite improvements in preoperative staging, surgical techniques, neoadjuvant/adjuvant options and postoperative care, there are still major difficulties in significantly improving survival, especially in locally advanced non-small cell lung cancer(NSCLC). To date, surgical resection is the primary mode of treatment for stage?Ⅰ?and Ⅱ NSCLC and has become an important component of the multimodality therapy of even more advanced disease with a curative intention. In fact, in NSCLC patients with solitary distant metastases, surgical interventions have been discussed in the last years. Accordingly, this review displays the recent surgical strategies implemented in the therapy of NSCLC patients. 展开更多

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. 展开更多

Currently, the first line therapy of choice is platinumbased combination chemotherapy. A therapeutic plateau has been reached with the prognosis for patients with advanced non-small cell lung cancer(NSCLC) remaining poor. New biomarkers of prognosis as well as new therapies focusing on molecular targets are emerging helping to identify patients who are likely to benefit from therapy. Despite this, drug resistance remains the major cause for treatment failure. In this article we review the role of apoptosis in mediating drug resistance in NSCLC. Better understanding of this fundamental biological process may provide a rationale for overcoming the current therapeutic plateau. 展开更多

Natural exosomes can express specific proteins and carbohydratemolecules on the surface and hence have demonstrated the great potentials for gene therapy of cancer.However,the use of natural exosomes is restricted by their low transfection efficiency.Here,we report a novel targeting tLyp-1 exosome by gene recombinant engineering for delivery of siRNA to cancer and cancer stem cells.To reach such a purpose,the engineered tLyp-1-lamp2b plasmids were constructed and amplified in Escherichia coli.The tLyp-1-lamp2b plasmids were further used to transfect HEK293T tool cells and the targeting tLyp-1 exosomes were isolated from secretion of the transfected HEK293T cells.Afterwards,the artificially synthesized siRNA was encapsulated into targeting tLyp-1 exosomes by electroporation technology.Finally,the targeting siRNA tLyp-1 exosomes were used to transfect cancer or cancer stem cells.Results showed that the engineered targeting tLyp-1 exosomes had a nanosized structure(approximately 100 nm)and high transfection efficiency into lung cancer and cancer stem cells.The function verifications demonstrated that the targeting siRNA tLyp-1 exosomes were able to knock-down the target gene of cancer cells and to reduce the stemness of cancer stem cells.In conclusion,the targeting tLyp-1 exosomes are successfully engineered,and can be used for gene therapy with a high transfection efficiency.Therefore,the engineered targeting tLyp-1 exosomes offer a promising gene delivery platform for future cancer therapy. 展开更多

Immune checkpoint inhibitors(ICIs),a type of immunotherapy,have become one of the most important therapeutic options for first-and second-line treatment of advanced non-small cell lung cancer(NSCLC).Recent clinical studies have shown that immunotherapy can offer substantial survival benefits to patients with early-stage or resectable advanced NSCLC.However,considering the importance of timing when using ICIs and their associated adverse events(AEs),the advantages and disadvantages of using these agents need to be weighed carefully when deciding the use of a combined treatment.In addition,the inconsistency between imaging assessment and pathological results poses further challenges to the evaluation of efficacy of neoadjuvant immunotherapy.It is also important to develop new methodologies and discover suitable biomarkers that can be used to evaluate survival outcomes of immunotherapy and identify patients who would benefit the most from this treatment.In this review,we aimed to summarize previous results of ongoing clinical trials on neoadjuvant immunotherapy for lung cancer and discuss the challenges and future perspectives of this therapeutic approach in the treatment of resectable NSCLC. 展开更多
