[PMID: 37718465 PMCID: PMC10626225 DOI: 10.1111/1759-7714.15106] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 08/28/2023] [Accepted: 08/29/2023] [Indexed: 09/19/2023] Open
Abstract
BACKGROUND The aim of this study was to investigate the efficacy of bevacizumab (Bev) in reducing peritumoral brain edema (PTBE) after stereotactic radiotherapy (SRT) for lung cancer brain metastases. METHODS A retrospective analysis was conducted on 44 patients with lung cancer brain metastases (70 lesions) who were admitted to our oncology and Gamma Knife center from January 2020 to May 2022. All patients received intracranial SRT and had PTBE. Based on treatment with Bev, patients were categorized as SRT + Bev and SRT groups. Follow-up head magnetic resonance imaging was performed to calculate PTBE and tumor volume changes. The edema index (EI) was used to assess the severity of PTBE. Additionally, the extent of tumor reduction and intracranial progression-free survival (PFS) were compared between the two groups. RESULTS The SRT + Bev group showed a statistically significant difference in EI values before and after radiotherapy (p = 0.0115), with lower values observed after treatment, but there was no difference in the SRT group (p = 0.4008). There was a difference in the distribution of EI grades in the SRT + Bev group (p = 0.0186), with an increased proportion of patients at grades 1-2 after radiotherapy, while there was no difference in the SRT group (p > 0.9999). Both groups demonstrated a significant reduction in tumor volume after radiotherapy (p < 0.05), but there was no difference in tumor volume changes between the two groups (p = 0.4089). There was no difference in intracranial PFS between the two groups (p = 0.1541). CONCLUSION Bevacizumab significantly reduces the severity of PTBE after radiotherapy for lung cancer. However, its impact on tumor volume reduction and intracranial PFS does not reach statistical significance.

Treatment-related adverse events of immune checkpoint inhibitors combined with angiogenesis inhibitors in advanced lung cancer: A systematic review and meta-analysis. Int Immunopharmacol 2023; 123:110785. [PMID: 37598630 DOI: 10.1016/j.intimp.2023.110785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 07/06/2023] [Accepted: 08/08/2023] [Indexed: 08/22/2023]
Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) with angiogenesis inhibitors have been used to treat advanced lung cancer. Their associated treatment-related adverse events (trAEs) are currently considered acceptable; however, no conclusion has been reached. We aimed to summarize the trAEs caused by ICIs combined with angiogenesis inhibitors in patients with advanced lung cancer. METHODS Pulled studies met the following criteria: patients with advanced lung cancer who received treatment involving ICIs combined with angiogenesis inhibitors (with or without chemotherapy) in interventional or observational studies. Results included the type and number of trAEs or immune-related adverse events (irAEs), treatment-associated discontinuation and mortality, overall survival (OS), and progression-free survival (PFS). PROSPERO CRD42022337656. RESULTS The study enrolled 32 trials involving 2313 patients who had 7768 any-grade trAEs and 1078 grade ≥3 trAEs. The pooled incidences were 87.33% (95% confidence interval [CI]: 79.49-93.65; I2 = 94.04%) for any-grade trAEs, and 38.63% (95% CI: 28.28-49.50; I2 = 95.61%) for grade ≥3 trAEs. There were 132 kinds of any-grade trAEs involving 18 systems, and 99 kinds of grade ≥3 trAEs involving 16 systems. For all trAEs, we observed significant differences in the line of therapy, trial design, therapy combination, and types of angiogenesis inhibitors (all P < 0.05). The rate of trAEs increased with dosage and frequency of medication. Pooled incidences of discontinuation and mortality were 10.64% and 0.81%, respectively. Nearly 647 patients experienced irAEs, including 636 any-grade irAEs and 154 grade ≥3 irAEs. CONCLUSIONS Overall, the incidence of trAEs caused by ICIs combined with angiogenesis inhibitors is generally acceptable. These trAEs have a wide spectrum nearly covering the full range of adverse events. Grade ≥3 trAEs are more closely associated with angiogenesis inhibitors than any grade. However, treatment-associated mortality remains concerning.

Abstract
PURPOSE Liver metastasis (LM) is common in non-small cell lung cancer (NSCLC), and always predicted worse outcomes with no effective therapy. We aimed to evaluate the effects and prognosis in LM patients treated with anlotinib. METHODS The present study is a post hoc analysis based on a multicenter, double-blind, phase 3 randomized clinical trial which designed to evaluate the efficacy and safety of anlotinib in patients with advanced NSCLC. A total of 437 patients were enrolled in present study, and 78 patients with LM. RESULTS Patients with LM showed a worse outcome compared to those without LM (PFS median, 2.6 vs 4.2 months), and OS (median, 5.6 vs 9.4 months, both P < 0.0001). The anlotinib was associated with longer PFS (median, 3.0 months) compared with placebo (median, 0.9 months), with a hazard ratio (HR) of 0.23 (95%CI, 0.12-0.42; P < 0.0001). Furthermore, OS was marginally significantly better in anlotinib group (median 6.6 months), compared with placebo (median 4.0 months), HR 0.61 (95%CI, 0.36-1.02; P = 0.055). Multivariate analysis confirmed normal peripheral blood LDH/TBiL level predicted better PFS and OS, lower ECOG score acted as independently prognostic factor for superior OS. Anlotinib was more associated with hand-foot syndrome (7.7% vs 0) and serum TSH level rise (7.7% vs 3.8%) and well tolerated, all AEs were no more than grade 3. CONCLUSION Patients with LM had a dismal prognosis, anlotinib could lead to a better PFS in pretreated NSCLC patients, which suggested anlotinib is a potential third-line or further therapy in these patients.

Abstract
Introduction Anlotinib, a novel multi-kinase inhibitor, was found to improve progression-free survival (PFS) in brain metastases. Methods This paper retrospectively analyzed 26 newly diagnosed or recurrent high-grade gliomas from 2017 to 2022, and the patients received oral anlotinib during concurrent postoperative chemoradiotherapy or after recurrence. Efficacy was evaluated according to the Response Assessment in Neuro-Oncology (RANO) criteria, and the main study endpoints were PFS at 6 months and overall survival (OS) at 1 year. Results After the follow-up, until May 2022, 13 patients survived and 13 patients died, with a median follow-up time of 25.6 months. The disease control rate (DCR) was 96.2% (25/26), and the overall response rate (ORR) rate was 73.1% (19/26). The median PFS after oral anlotinib was 8.9 months (0.8-15.1), and the PFS at 6 months was 72.5%. The median OS after oral anlotinib was 12 months (1.6-24.4), and the OS at 12 months was 42.6%. Anlotinib-related toxicities were observed in 11 patients, mostly grades 1-2. In the multivariate analysis, patients with Karnofsky Performance Scale (KPS) above 80 had a highermedian PFS of 9.9months (p = 0.02), and their sex, age, IDH mutation, MGMTmethylation, and whether anlotinib was combined with chemoradiotherapy or maintenance treatment had no effect on PFS. Conclusion We found that anlotinib combined with chemoradiotherapy in treating high-grade central nervous system (CNS) tumors can prolong PFS and OS and that it was safe.

Abstract
Prostate adenocarcinoma (PRAD) occurs only in males and has a higher incidence rate than other cancers. NPM1 is a nucleocytoplasmic shuttling protein that participates in the development of multiple tumours. The aim of this research was to explore the effect of the upregulation or downregulation of the NPM1 protein on the malignancy of prostate cancer and its possible signalling pathway. Prostate adenocarcinoma cell lines were used in this study, including RWPE-1, PC3, LNCap, and 22RV1 cells. Our research revealed that NPM1 was widely expressed in the PRAD cell lines, as determined by Western blotting, and that the levels of NPM1 protein were positively correlated with the degree of malignancy of the PRAD cell lines. Through interference and overexpression experiments, we found that PC3 cells growth was inhibited after NPM1 knockdown and that this inhibition was partly reversed by CTNNB1 overexpression; in contrast, PC3 cells growth was promoted after NPM1 overexpression, and this promotion was partly reversed by CTNNB1 knockdown, suggesting that NPM1 and CTNNB1 play important roles in the progression of prostate cancer cells via the Wnt/β-catenin signalling pathway. NPM1 may serve as an important biomarker and candidate therapeutic for patients with prostate cancer.

Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) is an aggressive tumor with high mortality. Circular RNAs (CircRNAs) played crucial roles in the development of cancers, including NSCLC. In this study, the action of circ_0006006 in NSCLC was investigated. METHODS Using real-time quantitative PCR (RT-qPCR), the relative gene expression was detected. The structure of circ_0006006 was identified using RNase R digestion and Actinomycin D treatment. The functional role of circ_0006006 in cell proliferation, migration, invasion, apoptosis and angiogenesis was explored using Cell Counting Kit-8 (CCK-8), EdU, colony formation, wound healing, transwell, flow cytometry, and tube formation assays, respectively. Using western blot, the relative proteins expression was measured. Dual-luciferase reporter and RNA immunoprecipitation (RIP) assays were employed to verify the correlation between microRNA-924 (miR-924) and circ_0006006 or serine/arginine-rich splicing factor 7 (SRSF7). Xenograft tumor experiment was used to investigate the effect of circ_0006006 on tumor growth in vivo. Immunohistochemistry (IHC) assay was performed to detect Ki-67, Bax, Bcl-2 and SRSF7 expression in tissues of mice. RESULTS Circ_0006006 was increased in NSCLC tissues and cells. Loss-of-function assays demonstrated that circ_0006006 silencing repressed the proliferative ability, cell migration and invasion, angiogenesis, and promoted cell apoptosis in A549 and H1299 cells. Follow-up mechanism experiments depicted that circ_0006006 sponged miR-924 and miR-924 inhibitor rescued circ_0006006 knockdown-mediated inhibition effect on the progression of NSCLC. Additionally, the inhibition effect of circ_0006006 knockdown on SRSF7 expression was reversed by miR-924 inhibitor. Moreover, the suppressive effect of miR-924 on NSCLC progression was reversed by SRSF7 overexpression. Xenograft tumor experiment unveiled that circ_0006006 knockdown inhibited tumor growth in vivo. CONCLUSION Circ_0006006 stimulated NSCLC progression by targeting miR-924 to regulate SRSF7 expression.

Abstract
Purpose: To investigate potential associations between selected laboratory markers (CRP, LDH, albumin, sodium, hemoglobin, neutrophils, and neutrophils/lymphocytes ratio [NLR]) and outcomes in patients with non-small cell lung cancer (NSCLC) treated with bevacizumab (BEV) plus chemotherapy. Patients and Methods: We retrospectively analyzed 105 patients with NSCLC from the Czech TULUNG registry treated at University Hospital in Pilsen with BEV + chemotherapy. Response to therapy was tested by Fisher's exact test. Survival statistics were evaluated using the Kaplan-Meier method and Cox analysis. Results: We showed significantly better disease control rate when CRP, albumin, hemoglobin, and NLR were within established “normal” values. In univariate analysis, normal values of CRP, LDH, albumin, sodium, hemoglobin, neutrophils, and NLR were associated with better overall survival (OS). Normal values of CRP, albumin, hemoglobin, neutrophils, and NLR were associated also with better progression-free survival (PFS). In a multivariate Cox model, normal values of LDH, albumin, and NLR were associated with significantly better OS while normal CRP, albumin, and NLR were associated with better PFS. Conclusions: LDH and sodium appear to be possible prognostic markers for BEV treatment in combination with chemotherapy in NSCLC. The parameters associated with inflammatory response (CRP, NLR, albumin, and possibly hemoglobin) appear to be promising predictive markers for this treatment combination.

Abstract
The interactions between the tumor microenvironment and the tumor cells confers a condition that accelerate or decelerate the development of tumor. Of these cells, mesenchymal stem cells (MSCs) have the potential to modulate the tumor cells. MSCs have been established with double functions, whereby contribute to a tumorigenic or anti-tumor setting. Clinical studies have indicated the potential of MSCs to be used as tool in treating the human cancer cells. One of the advantageous features of MSCs that make them as a well-suited tool for cancer therapy is the natural tumor-trophic migration potential. A key specification of the tumor development has been stablished to be angiogenesis. As a result, manipulation of angiogenesis has become an attractive approach for cancer therapy. This review article will seek to clarify the anti-angiogenesis strategy in modulating the MSCs to treat the tumor cells.

Hesperidin administration suppresses the proliferation of lung cancer cells by promoting apoptosis via targeting the miR‑132/ZEB2 signalling pathway. Int J Mol Med 2020; 46:2069-2077. [PMID: 33125117 PMCID: PMC7595658 DOI: 10.3892/ijmm.2020.4756] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Accepted: 06/10/2020] [Indexed: 01/10/2023] Open
Abstract
This aim of the present study was to identify the relationship between hesperidin and microRNA (miR)-132, and to study the role of hesperidin and miR-132 in the pathogenesis of non-small cell lung cancer (NSCLC). Computational analysis and luciferase assays were performed to identify the target of miR-132. Subsequently, reverse transcription-quantitative PCR and western blot assays were used to detect the effect of miR-132 and hesperidin on the expression of haematological and neurological expressed 1 (HN1) and zinc finger E-box binding homeobox 2 (ZEB2). Finally, MTT assays and flow cytometry analysis were used to investigate the effect of hesperidin on cell proliferation and apoptosis. ZEB2 was identified as a target gene of miR-132, and transfection with miR-132 mimic reduced the luciferase activity of the wild-type ZEB2 3′-untranslated region (3′-UTR) but not that of the mutant ZEB2 3′-UTR. By contrast, neither transfection with miR-132 mimic nor hesperidin treatment affected HN1 expression. Furthermore, hesperidin evidently inhibited cell proliferation and promoted apoptosis in a dose-dependent manner. Furthermore, the tumour volume in rats transplanted with NSCLC cells and treated with hesperidin was notably smaller compared with that in rats transplanted with NSCLC cells alone, while treatment with hesperidin significantly reduced the colony formation efficiency of NSCLC cells by increasing miR-132 expression and decreasing ZEB2 expression. To the best of our knowledge, the present study demonstrated for the first time that the administration of hesperidin decreased the expression of ZEB2 by upregulating the expression of miR-132, which in turn promoted apoptosis and inhibited the proliferation of NSCLC cells.

The Impact of Anlotinib on Brain Metastases of Non-Small Cell Lung Cancer: Post Hoc Analysis of a Phase III Randomized Control Trial (ALTER0303). Oncologist 2020; 25:e870-e874. [PMID: 32077550 DOI: 10.1634/theoncologist.2019-0838] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Accepted: 01/06/2020] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Anlotinib has been shown to prolong progression-free survival (PFS) and overall survival (OS) for non-small cell lung cancer (NSCLC). Herein we sought to analyze the effect of anlotinib in managing brain metastases (BM) and its brain-associated toxicities. METHODS The PFS and OS of anlotinib versus placebo in those with and without BM recorded at baseline were calculated and compared respectively. Time to brain progression (TTBP), a direct indicator of intracranial control, was also compared between anlotinib and placebo. All calculations were adjusted for confounding factors, including stage, histology, driver mutation type, and therapy history. RESULTS A total of 437 patients were included; 97 cases were recorded with BM at baseline. For patients with BM at baseline, anlotinib was associated with longer PFS (hazard ratio [HR], 0.29; 95% confidence interval [CI], 0.15-0.56) and OS (HR, 0.72; 95% CI, 0.42-1.12), presenting similar extent of improvement in those without BM (PFS: HR, 0.33; 95% CI, 0.24-0.45; OS: HR, 0.67; 95% CI, 0.50-0.91). Specifically, the intracranial objective response rate was 14.3% and the disease control rate was 85.7% in patients with BM who were treated with anlotinib. Anlotinib was associated with longer TTBP (HR, 0.11; 95% CI, 0.03-0.41; p = .001) despite all confounders. Additionally, anlotinib was associated with more neural toxicities (18.4% vs. 8.4%) and psychological symptoms (49.3% vs. 35.7%) but not with infarction or cerebral hemorrhage. CONCLUSION Anlotinib can benefit patients with advanced NSCLC with BM and is highly potent in the management of intracranial lesions. Its special effect on BM and cerebral tissue merits further investigation. (ClinicalTrials.gov ID: NCT02388919).

Abstract
The vascular endothelial growth factor (VEGF)/VEGF receptor 2 (VEGFR2) signaling pathway is one of the most important pathways responsible for tumor angiogenesis. Currently, two monoclonal antibodies, anti-VEGF-A antibody Bevacizumab and anti-VEGFR2 antibody Ramucizumab, have been approved for the treatment of solid tumors. At the same time, VEGF/VEGFR2 signaling is involved in the regulation of immune responses. It is reported that the inhibition of this pathway has the capability to promote vascular normalization, increase the intra-tumor infiltration of lymphocytes, and decrease the number and function of inhibitory immune cell phenotypes, including Myeloid-derived suppressor cells (MDSCs), regulatory T cells (Tregs) and M2 macrophages. On this basis, a number of clinical studies have been performed to investigate the therapeutic potential of VEGF/VEGFR2-targeting antibodies plus programmed cell death protein 1 (PD-1)/ programmed cell death ligand 1 (PD-L1) inhibitors in various solid tumor types. In this context, VEGF/VEGFR2- targeting antibodies, Bevacizumab and Ramucizumab are briefly introduced, with a description of the differences between them, and the clinical studies involved in the combination of Bevacizumab/ Ramucizumab and PD-1/PD-L1 inhibitors are summarized. We hope this review article will provide some valuable clues for further clinical studies and usages.

Abstract
Background Previous meta-analyses have shown paradoxical increased risk of bleeding and thrombotic events in patients receiving antiangiogenics (AA) that may be simply explained by the studies design included. By a meta-epidemiological approach, we aim to investigate the impact of double-blind (DB) and open-label study designs on the risks of bleeding, venous thrombotic events (VTE) and arterial thrombotic events (ATE) in cancer patients treated with AA. Materials and methods We searched Medline, Cochrane, ClinicalTrials.gov databases and proceedings of major oncology congresses for clinical trials published from January 2003 to January 2016. Randomized clinical trials that assigned patients with solid cancers to AA or control groups were eligible for inclusion. Combined odds ratios (ORs) for the risks of bleeding events, VTE and ATE were calculated for open and DB trials. Estimation bias of the treatment effect was determined by the ratio of OR, by dividing the OR values obtained in open-label trials by those obtained in DB trials. Results The literature-based meta-analysis included 166 trials (72 024 patients). For bleeding events, comparison of AA versus control yielded an overall OR of 2.41 [95% confidence interval (95% CI) 2.12-2.73; P < 0.001], but this risk was overestimated by 1.68 (95% CI 1.33-2.13) in open-label studies. Concerning VTE, the OR was 1.19 (95% CI 1.04-1.35; P = 0.012) overall with AA, but this effect disappears when considering only DB trials (OR 0.99, 95% CI 0.83-1.17). The corresponding ratio of OR showed a significant overestimation of 1.53 (95% CI 1.19-1.96) in open-label trials. For ATE, an OR of 1.59 (95% CI 1.30-1.94; P < 0.001) was observed, associated with a significant overestimation of 1.65 (95% CI 1.13-2.43) in open-label trials. Conclusions Open-label studies overestimated the risk of vascular adverse events with AA by at least 50%. Meta-analyses assessing adverse drug events should therefore be restricted to DB randomized trials.

Abstract
Tumor microenvironment interacts with tumor cells, establishing an atmosphere to contribute or suppress the tumor development. Among the cells which play a role in the tumor microenvironment, mesenchymal stem cells (MSCs) have been demonstrated to possess the ability to orchestrate the fate of tumor cells, drawing the attention to the field. MSCs have been considered as cells with double-bladed effects, implicating either tumorigenic or anti-tumor activity. On the other side, the promising potential of MSCs in treating human cancer cells has been observed from the clinical studies. Among the beneficial characteristics of MSCs is the natural tumor-trophic migration ability, providing facility for drug delivery and, therefore, targeted treatment to detach tumor and metastatic cells. Moreover, these cells have been the target of engineering approaches, due to their easily implemented traits, in order to obtain the desired expression of anti-angiogenic, anti-proliferative, and pro-apoptotic properties, according to the tumor type. Tumor angiogenesis is the key characteristic of tumor progression and metastasis. Manipulation of angiogenesis has become an attractive approach for cancer therapy since the introduction of the first angiogenesis inhibitor, namely bevacizumab, for metastatic colorectal cancer therapy. This review tries to conclude the approaches, with focus on anti-angiogenesis approach, in implementing the MSCs to combat against tumor cell progression.

Abstract
Background Lung cancer is a common tumor. Non-small-cell lung cancer (NSCLC) accounts for over 85% of lung cancer and has a high degree of malignancy. Angiogenesis plays an important role in NSCLC progression. Some studies have found that PVT1 can promote angiogenesis in tumor tissues, but the role of PVT1 in angiogenesis in NSCLC, as well as the underlying mechanism, is unclear. Material/Methods To explore the role of PVT1 in NSCLC, qRT-PCR, Western blot, luciferase reporter assay, and ELISA were carried out for detecting the relationship among PVT1, miR-29c, and VEGF. Tube formation assay was used to assess the role of PVT1 in angiogenesis in NSCLC. Results Our results showed that higher PVT1 was expressed in NSCLC and the elevated PVT1 was closely related to angiogenesis and poor prognosis in NSCLC. Further functional analysis showed that higher PVT1 expression could promote angiogenesis by regulating VEGF in NSCLC. Mechanistically, the luciferase reporter assay confirmed that VEGF was the targeted gene of miR-29c. In addition, we found that miR-29c is an inhibitory target of PVT1. Conclusions We found that PVT1 promotes angiogenesis through targeting the miR-29c/VEGF signaling pathway in NSCLC.

Abstract
BACKGROUND This study aimed to investigate the effects of metastasis-associated 1 (MTA1) gene expression and gene silencing in human non-small cell lung cancer (NSCLC) cells in vitro and on angiogenesis in tumor xenografts in vivo in nude mice. MATERIAL AND METHODS Human H460 and H1299 NSCLC cell lines underwent transfection with lentiviral transfer plasmids (lenti) and short-interfering RNA (si-RNA) and included a control group, a lenti-MTA1 group, a lenti-si-MTA1 group, a lenti control group, and a si-RNA control group. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect MTA1 gene expression after cell transfection. MTA1 transfection was more effective in H460 cells, which were selected for further in vivo studies. Sixty Balb/c nude mice, containing human H460 cell tumor xenografts, included a control group (N=20), a lenti-MTA1 group (N=20), and a lenti-si-MTA1 group (N=20). Tumor tissue immunohistochemistry was used to detect the expression of MTA1 protein and microvessel density (MVD) using CD31. Western blot was used to quantify the expression of cyclooxygenase-2 (COX-2), angiopoietin 1/2 (Ang1/2), hypoxia-inducible factor 1-a (HIF-1a), and vascular endothelial growth factor (VEGF). RESULTS MTA1 silencing with si-RNA significantly reduced the tumor growth rate in nude mice (p<0.01), reduced tumor MVD, and 70% of mice survived for more than 30 days. MTA1 overexpression resulted in the death of all mice at 30 days after tumor inoculation and upregulated the expression of COX-2, Ang1/2, HIF-1a and VEGF, which were down-regulated by MTA1 silencing. CONCLUSIONS MTA1 gene expression promoted angiogenesis in mouse xenografts from human NSCLC cells.

Abstract
Background This study was designed to assess the clinical efficacy and toxicity of apatinib (YN968D1) as third or subsequent‐line treatment for stage III/IV non‐small cell lung cancer (NSCLC). Methods A total of 100 patients with advanced NSCLC who were treated with apatinib at a daily dose of 250/425/500 mg at Shandong Cancer Hospital from January 2016 to June 2018 were enrolled in our study. The objective response, disease control, and median progression‐free survival rates were reviewed and evaluated. Univariate and multivariate analyses were performed to determine the prognostic factors. The main adverse events were evaluated per the Common Terminology Criteria for Adverse Events version 4.0. Results All patients were assessable for response. No complete responses were observed, 11 patients achieved a partial response, and 56 showed stable disease. The objective response rate was 11.0%, the disease control rate was 67.0%, and the median progression‐free survival was 2.93 months (95% confidence interval 2.07–3.87). In Cox regression analysis, the Eastern Cooperative Oncology Group performance status score (hazard ratio 1.799; P < 0.05) and smoking history (hazard ratio 1.958; P < 0.05) were predictive indicators for apatinib treatment efficacy. Treatment‐related adverse events were tolerated, predictable, reversible, and controllable. Conclusion Apatinib was found to be both effective and safe in advanced NSCLC patients without a genetic driver mutation who experienced progression after two or more lines of chemotherapy treatment.

[PMID: 29604270 DOI: 10.1016/j.lfs.2018.03.046] [Citation(s) in RCA: 40] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2017] [Revised: 03/13/2018] [Accepted: 03/23/2018] [Indexed: 12/24/2022]
Abstract
OBJECTIVE The present study aimed to investigate the ability of hesperidin to suppress the migration and invasion of A549 cells, and to investigate the role of the SDF-1/CXCR-4 cascade in this suppression. METHODS We performed a Transwell migration assay to measure the migratory capability of A549 cells treated with 0.5% DMSO, SDF-1α, AMD3100 or hesperidin. The SDF-1 level in the culture medium was determined by an enzyme-linked immunosorbent assay (ELISA) to detect whether different concentrations of hesperidin affected SDF-1 secretion. A wound-healing assay was performed to determine the effects of different concentrations of hesperidin on the migration inhibition of A549, H460 and H1975 cells. Additionally, the effect of various hesperidin concentrations on the rate of A549 cell invasion and migration was examined with and without Matrigel in Transwell assays, respectively. Western blot analysis was used to evaluate the protein levels of CXCR-4, MMP-9, CK-19, Vimentin, p65, p-p65, p-IκB, IκB, p-Akt and Akt. RT-qPCR was used to detect the mRNA levels of CXCR-4, MMP-9, CK-19, Vimentin, p65, IκB, SDF-1 and Akt. RESULTS The Transwell migration assay indicated that SDF-1α promoted A549 cell migration, while AMD3100 and hesperidin significantly inhibited the migratory capability. The wound-healing assay demonstrated that hesperidin treatment significantly reduced the rate of wound closure compared with the control group in a dose-dependent manner. Similarly, the migration and invasive abilities of A549 cells, H460 and H1975 cells treated with hesperidin were significantly decreased compared with the control group. The ELISA data suggested that hesperidin attenuated the secretion of SDF-1 from A549 cells in a dose-dependent manner. Furthermore, western blot analysis indicated that SDF-1α treatment significantly increased the levels of CXCR-4, p-p65, p-IκB and p-Akt in A549 cells. In contrast, AMD3100 or hesperidin reversed the effect induced by SDF-1α through decreasing the expression of CXCR-4. Subsequent RT-qPCR and western blot analyses also confirmed that hesperidin had a significant effect on the expression of EMT-related proteins, including MMP-9, CK-19 and Vimentin, in A549 cells. CONCLUSION In summary, we demonstrated that hesperidin inhibited the migratory and invasive capabilities of A549 human non-small cell lung cancer cells by the mediation of the SDF-1/CXCR-4 signaling cascade, thus providing the foundation for the development of hesperidin as a safer and more effective anticancer drug for non-small cell lung cancer.

Abstract
In recent years, lymphangiogenesis, the process of lymphatic vessel formation from existing lymph vessels, has been demonstrated to have a significant role in diverse pathologies, including cancer metastasis, organ graft rejection, and lymphedema. Our understanding of the mechanisms of lymphangiogenesis has advanced on the heels of studies demonstrating vascular endothelial growth factor C as a central pro-lymphangiogenic regulator and others identifying multiple lymphatic endothelial biomarkers. Despite these breakthroughs and a growing appreciation of the signaling events that govern the lymphangiogenic process, there are no FDA-approved drugs that target lymphangiogenesis. In this review, we reflect on the lessons available from the development of antiangiogenic therapies (26 FDA-approved drugs to date), review current lymphangiogenesis research including nanotechnology in therapeutic drug delivery and imaging, and discuss molecules in the lymphangiogenic pathway that are promising therapeutic targets.

Efficacy and safety of angiogenesis inhibitors in small-cell lung cancer. Oncotarget 2018; 8:1141-1155. [PMID: 27901478 PMCID: PMC5352042 DOI: 10.18632/oncotarget.13588] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2016] [Accepted: 11/09/2016] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVE The purpose of this study was to investigate the efficacy and safety of angiogenesis inhibitors for small-cell lung cancer (SCLC). METHODS Totally, 16 controlled trials (1898 cases) involving angiogenesis inhibitors plus chemotherapy (ACT group) versus chemotherapy alone group (CT group) were identified from PubMed, EMBASE, Cochrane Library and Wanfang Data before March 2016. RESULTS Compared with CT group, ACT group obtained a significant benefit on objective response rate (ORR) (RR = 1.34; 95% CI = 1.19-1.51; P < 0.00001) and a trend of prolonging progression-free survival (PFS) (HR = 0.86; 95% CI = 0.73-1.01; P = 0.07) without improving overall survival (OS) (HR = 1.05; 95% CI = 0.94-1.17; P = 0.36). Remarkably, subgroup analysis showed that the antibodies targeting VEGF significantly prolonged PFS (HR = 0.76; 95% CI = 0.64-0.90; P = 0.001). With regard to toxicity, there was no significant difference in severe adverse events (AEs, Grade≥3) between two groups except that gastrointestinal symptom, hypertension, metabolic disorders, neurology and pain were higher in ACT group. CONCLUSION Compared with chemotherapy alone, antibodies targeting VEGF plus chemotherapy significantly improved ORR and prolonged PFS with an acceptable toxicity profile for patients with SCLC. Therefore, angiogenesis inhibitors, especially antibodies targeting VEGF, combining with chemotherapy may be a potential promising strategy in managing SCLC.

Abstract
The highly selective multi‐targeted agent sorafenib is an inhibitor of a number of intracellular signaling kinases with anti‐proliferative, anti‐angiogenic and pro‐apoptotic effects in various types of tumors, including human non‐small cell lung cancer (NSCLC). Betulin displays a broad spectrum of biological and pharmacological properties, including anticancer and chemopreventive activity. Combination of drugs with different targets is a logical approach to overcome multilevel cross‐stimulation among key signaling pathways in NSCLC progression. NSCLC cell lines, A549, H358 and A427, with different KRAS mutations, and normal human peripheral blood lymphocyte cells, were treated with sorafenib and betulinic acid alone and in combination. We examined the effect of different combined treatments on viability (MTS test), proliferation and apoptotic susceptibility based on flow cytometry, alterations in signaling pathways by western blotting and colony‐forming ability. The combination of sorafenib with betulinic acid had a strong effect on the induction of apoptosis of different NSCLC cell lines. In addition, this combination was not toxic for human peripheral blood lymphocytes. Combination treatment changed the expression of proteins involved in the mitochondrial apoptosis pathway and induced apoptotic death by caspase activation. Importantly, combination treatment with low drug concentrations tremendously reduced the colony‐forming ability of A549, H358 and A427 cells, as compared to both compounds alone. In this study, we showed that combination therapy with low concentrations of sorafenib and betulinic acid had the capacity to induce high levels of cell death and abolish clonogenic activity in some NSCLC cell lines regardless of KRAS mutations.

Abstract
Despite new treatment options in lung cancer, there is still a need for better biomarkers to assist in therapy decisions. Angiogenesis has been associated with tumour growth and dissemination, and the vascular proliferation index (VPI) is a valuable prognostic marker in other tumours. Nestin, a marker of immature endothelium, was previously applied in combination with Ki67 for proliferating endothelium as a novel marker (Nestin‐Ki67) of ongoing angiogenesis. Here, the prevalence and prognostic impact of vascular proliferation on lung cancer‐specific survival (LCSS) in lung adenocarcinomas was studied. Selected tumour slides from a cohort of 210 patients treated surgically for adenocarcinoma at Haukeland University Hospital (Norway) from 1993 to 2010 were stained for Nestin‐Ki67. VPI, the ratio between the density of proliferating vessels and the overall microvessel density were used, and the cut‐off value was set at 4.4% (upper quartile). High VPI was associated with the presence of blood vessel invasion (p = 0.007) and tumour necrosis (p = 0.007). Further, high VPI was significantly associated with reduced LCSS (p = 0.020). By multivariate analysis, VPI remained an independent prognostic factor for reduced LCSS (HR 1.7; 95% CI 1.04–2.68; p = 0.033) when adjusted for other prognostic clinico‐pathological features. In conclusion, microvessel proliferation assessed using the VPI was associated with aggressive tumour features such as blood vessel invasion and tumour necrosis and, independently, decreased LCSS. This marker should be further explored in separate cohorts, and in trials of anti‐angiogenesis therapy.

Abstract
A series of antibodies against vascular endothelial growth factor (VEGF) have been developed for the treatment of various types of cancer, including non-small cell lung cancer (NSCLC) in recent years. However, tumors frequently demonstrate resistance to these strategies of VEGF inhibition. Efforts to better understand the mechanism underlying the acquired resistance to anti-VEGF antibodies are warranted. In the present study, in order to develop a xenograft model of acquired resistance to anti-VEGF antibody, xenografts of human adenocarcinoma A549 cells were generated through the successive inoculation of tumor tissue explants into first (F1), second (F2) and third (F3) generations of mice treated with the anti-VEGF antibody B20. Tumor growth rate and vessel-forming ability, assessed via cluster of differentiation (CD) 31 staining, were significantly lower in the F1, F2 and F3 groups compared with in the F0 control group (P<0.01), suggesting that drug resistance was not successfully acquired. The percentages of CD11b+ myeloid-derived suppressor cells and lymphocyte antigen 6C (Ly6C)+ subsets were significantly smaller in F1, F2 and F3 groups compared with in F0 (P<0.01). However, the ratio of Ly6C+ to CD11b+ cells was significantly higher in the F3 group compared with in F0 and F1 groups (P<0.01), indicating increasing recruitment of the Ly6C+ subset with successive challenges with the anti-VEGF antibody. In conclusion, the recruitment of CD11b+Ly6C+ monocytes increased with successive generations of NSCLC-xenografted mice challenged by B20, an anti-VEGF agent.

Abstract
Background/Aims The use of antiangiogenic agents (AAs) in cancer treatment has increased because they offer survival benefit in combination with cytotoxic chemotherapy. Given their potential to cause gastrointestinal (GI) perforation and bleeding, it is currently recommended that AAs be held for 28 days before and after surgery. However, there are no specific guidelines which address their use around endoscopic procedures because data regarding the safety of endoscopy in cancer patients while on AAs is scarce despite the fact that these patients often require endoscopy. This study investigated the safety of endoscopy in cancer patients receiving AAs. Methods This is a retrospective multicenter study of a consecutive case series of 445 cancer patients undergoing endoscopy within 31 days of administration of AAs at 5 specialized cancer centers between April 2008 and August 2014. Endoscopies were classified into two different categories based on the risk of GI bleeding and perforation: low and high. The primary outcome measures were procedure-related adverse events (AEs) and death within 30 days of endoscopy. The severity of AEs was classified according to the common terminology criteria for adverse events (CTCAE) version 4.0. The incidence of AEs and mortality was calculated using the total number of patients as the denominator. Results 445 cancer patients with a mean age of 54 years underwent a total of 545 endoscopies. Median time duration from AAs to endoscopy was 11 days. Of 545 endoscopic procedures, 398 (73%) were low-risk and 147 (27%) were high-risk. There were 3 procedure-related AEs: esophageal perforation (grade 3) two days after an EGD, pancreatitis (grade 5) a day after failed ERCP, and bleeding from the gastrostomy site (grade 1) two days after an EGD. Of 445 patients, 29 (6.5%) died within 30 days of the procedure with no deaths deemed procedure-related. The most common causes of death were terminal cancer (n = 10), hepatic decompensation (n = 5) and sepsis (n = 4). Conclusion In this retrospective study, the rate of endoscopy-related AEs in patients on AAs appears to be low when performed in specialized cancer centers. However, future prospective studies are needed to confirm this finding.

Abstract
Understanding the interaction between cancer cells and immunocytes will inspire new cancer therapy strategies. However, how cancer-derived circulating miRNAs modulate such interaction remains unclear. Here we discovered that circulating miR-410-5p, secreted by prostate cancer cells, entered dendritic cells (DCs), with the aid of argonaute-2 protein. The cancer cell antigens stimulated the DCs to produce miR-410-3p, a highly complementary counterpart of miR-410-5p derived from pre-miR-410. The DC-internalized miR-410-5p degraded the miR-410-3p by base pairing and thus inhibited its function in suppressing tumor angiogenesis, promoting tumor growth. Furthermore, blockade of the miR-410-5p upregulated the miR-410-3p to inhibit tumor growth. Our work suggests a new miRNA-mediated role of immunocytes in cancer progression and a new strategy of cancer therapy through suppressing circulating miRNAs.

Abstract
We conducted a meta-analysis to evaluate the efficacy of adding any antiangiogenic therapy (AT) to the standard of care in advanced non-small-cell lung cancer (NSCLC). The electronic databases Ovid PubMed, Cochrane Central Register of Controlled Trials, and Embase were searched to identify eligible trials. We included all phase III randomized trials with any line and type of treatment, histology. and AT dose. Pooled hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS), and pooled odds ratio (OR) for overall response rates (RR) were calculated. We divided the population into 2 subgroups based on the bevacizumab dose. Data of 19,098 patients from 25 phase III trials were analyzed. Compared with the standard of care, the addition of AT did not prolong OS (HR 0.98; 95% confidence interval [CI], 0.96-1.00; P = .1 and HR 0.97; 95% CI, 0.94-1.00; P = .06 for groups 1 and 2, respectively). However, there was a significant improvement in PFS with the addition of AT (HR 0.85; 95% CI, 0.79-0.91; P < .00001 and HR 0.81; 95% CI, 0.75-0.88; P < .00001 for groups 1 and 2, respectively) and overall RR (OR 1.61; 95% CI, 1.30-2.01; P < .0001 and OR 1.72; 95% CI, 1.39-2.14; P < .00001 for groups 1 and 2, respectively). This is the first meta-analysis including only all phase III trials with AT in NSCLC showing no significant effect on OS and an improvement in PFS and RR only. The role of AT in advanced NSCLC is still questionable; strong validated biomarkers are eagerly needed to predict which subgroup might benefit the most from such therapy.

Abstract
Angiogenesis has become an attractive target for cancer therapy since the US Food and Drug Administration (FDA) approved the first angiogenesis inhibitor (bevacizumab) for the treatment of metastatic colorectal cancer in 2004. In following years, a large number of angiogenesis inhibitors have been discovered and developed, ranging from monoclonal antibodies, endogenous peptides, to small organic molecules and microRNAs. Many of them are now entering the clinical trial, or achieving approval for clinical use. However, major limitations have been observed about angiogenesis inhibitors by continued clinical investigations, such as resistance, enhancing tumor hypoxia and reducing delivery of chemotherapeutic agents, which might be the main reason for poor improvement in overall survival after angiogenesis inhibitor administration in clinic. Therefore, optimal anti-angiogenic therapy strategies become critical. The present review summarizes recent researches in angiogenesis inhibitors, and proposes a perspective on future directions in this field.

Abstract
BACKGROUND Trials investigating the efficacy and safety of combining molecular targeted agent (MTA) with platinum-gemcitabine (PG) in first-line treatment of advanced non-small cell lung cancer (NSCLC) have shown inconsistent findings. This meta-analysis aimed to explore whether the addition of MTAs to PG in NSCLC could provide a survival benefit with a tolerable toxicity. METHODS Web of knowledge, PubMed, Ovid, Embase, and Cochrane Library were searched to identify relevant studies and extract data on overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and common grade 3 or 4 adverse events. Subgroup analyses were conducted on the basis of race and the type of MTA. RESULTS Twelve trials with a total of 6143 patients were included in this meta-analysis. Compared with PG chemotherapy, combination therapy of MTA with PG did not improve OS (hazard ratio [HR] = 0.96, 95% confidence interval [CI] = 0.90-1.01) but improved PFS (HR = 0.77, 95% CI = 0.66-0.89) and ORR (risk ratio [RR] = 1.33, 95% CI = 1.11-1.60). Subanalysis indicated that there was more incidence of grade 3 or 4 rash (RR = 11.20, 95% CI = 6.07-20.68), anemia (RR = 1.21, 95% CI = 1.01-1.46), diarrhea (RR = 2.62, 95% CI = 1.21-5.65), and anorexia (RR = 2.08, 95% CI = 1.12-3.88) in combining epidermal growth factor receptor targeted therapy group compared to PG group. An increased risk of grade 3 or 4 rash (RR = 5.08, 95% CI = 1.53-16.79), thrombocytopenia (RR = 1.50, 95% CI = 1.03-2.18), and hypertension (RR = 2.36, 95% CI = 1.05-5.32) was observed in sorafenib combination group. CONCLUSION The combination of PG plus MTA was superior to PG alone in terms of PFS and ORR but not in OS. The combination chemotherapy also showed a higher frequency of grade 3 or higher toxic effects in patients with advanced NSCLC than PG chemotherapy.

Abstract
Central nervous system (CNS) metastases are common in patients with advanced non-small cell lung cancer (NSCLC), occurring in 24% to 44% of patients in the course of their disease and confer significant morbidity and mortality. Systemic therapies have been deemed ineffective in brain metastases (BM) under the hypothesis that the blood-brain barrier (BBB) limits their delivery to the brain. Angiogenesis, which is mainly mediated by vascular endothelial growth factor (VEGF) pathway, is crucial for tumor survival, growth and invasion both in primary and metastatic brain lesions. Two major categories of agents have been developed to target this pathway: antibody-based agents and VEGF receptor tyrosine kinase inhibitors (TKIs). Clinical benefits have been shown with anti-angiogenetic therapies in the treatment of metastatic NSCLC. However, patients with CNS metastases were often excluded from trials with these agents, due to concerns about a potentially greater risk of cerebral haemorrhage and thromboembolic disease. Therefore, the overall efficacy and safety of angiogenetic agents in patients with BM from NSCLC are yet to be clarified. This paper aims to review available data about the efficacy and safety of anti-angiogenetic therapies for CNS metastases in NSCLC patients.

Abstract
Background/Objective Vascular endothelial growth factor (VEGF) is the most important promotor of angiogenesis. Some studies indicate that anti-angiogenic agents that interfere with VEGF and its receptor (VEGFR), i.e., anti-VEGF/VEGFR agents, may be applied to treat endometriosis. This meta-analysis investigated the efficacy of anti-VEGF/VEGFR agents in animal models of endometriosis. Methods A systematic literature search was performed for animal studies published in English or Chinese from January 1995 to June 2016, which evaluated the effect of anti-VEGF/VEGFR agents on endometriosis. The databases were: PubMed, Web of Science, BIOSIS, Embase, and CNKI. The quality of included studies was assessed using the SYRCLE tool. The random-effect models were used to combine the results of selected studies. Heterogeneity was assessed using H2statistic and I2 statistic. Subgroup analyses were performed to determine the source of heterogeneity in endometriosis scores and follicle numbers. Results We identified 13 studies that used anti-VEGF/VEGFR agents in various animal models. The meta-analysis showed that anti-VEGF/VEGFR agents were associated with smaller size (standardized mean difference (SMD) –0.96, 95% CI –1.31 to –0.62; P < 0.0001) and weight (SMD –1.70, 95% CI –2.75 to –0.65; P = 0.002) of endometriosis lesions, relative to the untreated controls, as well as a lower incidence rate of endometriosis (risk ratio 0.26, 95% CI 0.07 to 0.93; P = 0.038) and endometriosis score (SMD –1.17, 95% CI –1.65 to –0.69; P < 0.0001); the number of follicles were similar (SMD –0.78, 95% CI –1.65 to 0.09; P = 0.08). Conclusions Anti-VEGF/VEGFR agents appeared to inhibit the growth of endometriosis, with no effect on ovarian function. Anti-angiogenic therapy may be a novel strategy in treating endometriosis.

Abstract
To perform this meta-analysis, we investigated the risk of the most clinically relevant adverse events related to antivascular endothelial growth factor receptor (VEGFR) agents in advanced nonsmall-cell lung cancer (NSCLC).A comprehensive literature search for studies published up to October 2015 was performed. Prospective randomized controlled phase II/III clinical trials that comparing therapy with or without anti-VEGFR agents for advanced NSCLC were included for analysis. Summary relative risk (RR) and 95% confidence intervals (CIs) were calculated using random effects or fixed effects according to the heterogeneity among included trials.A total of 11,701 patients from 18 clinical trials were included for analysis. Pooled RR showed that the use of anti-VEGFR agents significantly increased the risk of developing hypertension (RR 4.71, 95% CI 3.29-6.73, P < 0.001) and fatal adverse events (RR 1.33, 95% CI 1.12-1.58, P = 0.001). No statistically significant differences were found for gastrointestinal (GI) perforation (P = 0.41), arterial or venous thromboembolic events (P = 0.49 and P = 0.16, respectively), or hemorrhagic events (P = 0.81). Sensitive analysis indicated that the significance estimate of pooled RR of fatal adverse event (FAEs) was not significantly influenced by omitting any single study.The use of anti-VEGFR agents in advanced NSCLC does significantly increase the risk of hypertension and fatal adverse events, but not for arterial or venous thromboembolic events, GI perforation, or hemorrhagic events.

Abstract
Targeted and sustained delivery of biologicals to improve neovascularization has been focused on stimulation angiogenesis. The formation of collaterals however is hemodynamically much more efficient, but as a target of therapy has been under-utilized. Although there is good understanding of the molecular processes involving collateral formation and there are interesting drugable candidates, the need for targeting and sustained delivery is still an obstacle towards safe and effective treatment. Molecular targeting with nanoparticles of liposomes is promising and so are peri-vascularly delivered polymer-based protein reservoirs. These developments will lead to future arteriogenesis strategies that are adjunct to current revascularization.

Abstract
Tumor cells become resistant after long-term use of anti-VEGF (vascular endothelial growth factor) agents. Our previous study shows that treatment with a VEGF inhibitor (VEGF-Trap) facilitates to develop tumor resistance through regulating angiogenesis-related genes. However, the underlying molecular mechanisms remain elusive. Histone modifications as a key epigenetic factor play a critical role in regulation of gene expression. Here, we explore the potential epigenetic gene regulatory functions of key histone modifications during tumor resistance in a mouse Lewis lung carcinoma (LLC) cell line. We generated high resolution genome-wide maps of key histone modifications in sensitive tumor sample (LLC-NR) and resistant tumor sample (LLC-R) after VEGF-Trap treatment. Profiling analysis of histone modifications shows that histone modification levels are effectively predictive for gene expression. Composition of promoters classified by histone modification state is different between LLC-NR and LLC-R cell lines regardless of CpG content. Histone modification state change between LLC-NR and LLC-R cell lines shows different patterns in CpG-rich and CpG-poor promoters. As a consequence, genes with different level of CpG content whose gene expression level are altered are enriched in distinct functions. Notably, histone modification state change in promoters of angiogenesis-related genes consists with their expression alteration. Taken together, our findings suggest that treatment with anti-VEGF therapy results in extensive histone modification state change in promoters with multiple functions, particularly, biological processes related to angiogenesis, likely contributing to tumor resistance development.

Abstract
Vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) might be new therapeutic strategies for advanced non-small cell lung cancer (NSCLC). Here a total of 12,520 patients from 23 randomized controlled trials (RCTs) were enrolled to evaluate the efficacy and safety of VEGFR-TKIs quantitatively in advanced NSCLC. Compared with non-VEGFR-TKIs, VEGFR-TKIs regimen significantly improved progression-free survival (PFS) [hazard ratio (HR): 0.839, 95% confidence interval (CI): 0.805-0.874, P < 0.001], objective response rates (ORR) [relative risk (RR): 1.374, 95% CI: 1.193-1.583, P < 0.001] and disease control rates (DCR) (RR: 1.113, 95% CI: 1.027-1.206, P = 0.009), but not overall survival (OS) (HR: 0.960, 95% CI: 0.921-1.002, P = 0.060) for NSCLC patients. The RR of all-grade neutropenia, thrombocytopenia, hypertension, hemorrhage, fatigue, anorexia, stomatitis, diarrhea, rash, hand-foot skin reaction (HFSR) were increased in patients received VEGFR-TKIs. As for high-grade (≥ 3) adverse events (AEs), VEGFR-TKIs were associated with higher RR of neutropenia, thrombocytopenia, hypertension, fatigue, stomatitis, diarrhea, rash and HFSR. This study demonstrates VEGFR-TKIs improve PFS, ORR and DCR, but not OS in advanced NSCLC patients. VEGFR-TKIs induce more frequent and serious AEs compared with control therapies.

Abstract
Therapeutic options in locally advanced non-small cell lung cancer (NSCLC) have expanded in the past decade to include a palate of targeted interventions such as high dose targeted thermal ablations, radiotherapy and growing platform of antibody and small molecule therapies and immunotherapies. Although these therapies have varied mechanisms of action, they often induce changes in tumour architecture and microenvironment such that response is not always accompanied by early reduction in tumour mass, and evaluation by criteria other than size is needed to report more effectively on response. Functional imaging techniques, which probe the tumour and its microenvironment through novel positron emission tomography and magnetic resonance imaging techniques, offer more detailed insights into and quantitation of tumour response than is available on anatomical imaging alone. Use of these biomarkers, or other rational combinations as readouts of pathological response in NSCLC have potential to provide more accurate predictors of treatment outcomes. In this article, the robustness of the more commonly available positron emission tomography and magnetic resonance imaging biomarker indices is examined and the evidence for their application in NSCLC is reviewed.

Abstract
The Fas receptor ligand FasL regulates immune cell levels by inducing apoptosis of Fas receptor-positive cells. Here, we studied the impact of host FasL on tumor development in mice. Genetically targeting FasL in naïve mice increased myeloid cell populations, but, in marked contrast, it reduced the levels of myeloid-derived suppressor cells (MDSC) in mice bearing Lewis lung carcinoma tumors. Analysis of the MDSC subset distribution revealed that FasL deficiency skewed cell populations toward the M-MDSC subset, which displays a highly immunosuppressive activity. Furthermore, tumor-bearing mice that were FasL-deficient displayed an enhanced proportion of tumor-associated macrophages and regulatory T cells. Overall, the immunosuppressive environment produced by FasL targeting correlated with reduced survival of tumor-bearing mice. These results disclose a new role for FasL in modulating immunosuppressive cells.

Abstract
Purpose We aimed at assessing the overall efficacy of angiogenesis inhibitor (AI)-containing regimens in the treatment of advanced non-small-cell lung cancer (NSCLC) according to histological types. Methods Studies from PubMed and Web of Science, and abstracts presented at American Society of Clinical Oncology (ASCO) meeting up to October 31, 2014 were searched to identify relevant studies. Eligible studies included prospective randomized controlled trials (RCTs) evaluating AIs in advanced NSCLC with survival data according to patients’ histologies. The endpoints were overall survival (OS) and progression-free survival (PFS). Statistical analyses were conducted by using either random effects or fixed effect models according to the heterogeneity of included studies. Results A total of 10,035 patients with advanced NSCLC from 13 RCTs were identified for analysis. The pooled results demonstrated that AI-containing regimens significantly improved the PFS (HR, 0.84, 95% confidence interval (CI): 0.78–0.91, P<0.001) and OS (HR, 0.92, 95% CI: 0.85–0.99, P=0.017) in lung adenocarcinoma when compared to non-AI-containing regimens. Additionally, there was a significantly improved PFS (HR, 0.87, 95% CI: 0.77–0.98, P=0.027) for AI-containing regimens in squamous cell lung carcinoma, but it did not translated into OS benefit (HR, 1.02, 95% CI: 0.92–1.15, P=0.68). For NSCLC patients with other histological types, the use of AIs did not significantly improve PFS (HR, 0.90, 95% CI: 0.75–1.09, P=0.27) and OS (HR, 0.90, 95% CI: 0.76–1.08, P=0.19). Conclusion The findings of this study suggest that the addition of AIs to the treatment therapies for patients with lung adenocarcinoma offers improved survival benefits. Prospective clinical trials investigating the role of AIs in this setting are recommended.

Abstract
Aim A study was conducted to determine the overall risk and incidence of hypertension with bevacizumab in non-small-cell lung cancer (NSCLC) patients. Materials and methods Electronic databases such as the Embase, PubMed, and Cochrane Library were searched for related trials. Statistical analyses were conducted to calculate the overall incidence rates, odds ratios (ORs), and 95% confidence intervals (CIs) by using either random-effect or fixed-effect models depending on the heterogeneity. Results A total of 3,155 subjects from nine studies were included. The overall incidences of all-grade and high-grade hypertension in NSCLC patients were 19.55% (95% CI 10.17%–34.3%) and 6.95% (95% CI 5.81%–8.30%). Bevacizumab use was associated with a significantly increased risk in all-grade hypertension (OR 8.07, 95% CI 3.87–16.85; P=0.0002) and high-grade hypertension (OR 5.93, 95% CI 3.41–10.32; P<0.0001). No evidence of publication bias was determined for the ORs of hypertension in our meta-analysis. Conclusion Bevacizumab is associated with a significantly increased risk of hypertension development in NSCLC patients. Early monitoring and effective management of hypertension might be important steps for the safe use of this drug.

Abstract
BACKGROUND This study was undertaken to analyze the characteristics of fever after cancer chemotherapy in order to reduce unnecessary medical care. METHODS Retrospectively, 1016 consecutive cycles of cancer chemotherapy were analyzed. Fever was defined as a temperature of ≥ 37.5 °C lasting for 1 h. Age, sex, tumor histology, the treatment regimen, the timing of fever onset, the number of days for which the fever persisted, the cause of the fever, the presence or absence of radiotherapy, and the use of granulocyte colony-stimulating factor (G-CSF) were examined. RESULTS The patients included 748 males and 268 females (median age = 68, range = 29-88), of whom 949, 52, and 15 were suffering from lung cancer, malignant pleural mesothelioma, and other diseases, respectively. Fever was observed in 367 cycles (36 %), including 280 cycles (37 %) involving males and 87 cycles (32 %) involving females. Fever occurred most commonly in the first cycles and was higher than later cycles (41 vs. 30 %, p < 0.001). Fever occurred most frequently on posttreatment days 4 (8 %), 3 (7 %), and 12 (7 %), and the distribution of fever episodes exhibited two peaks on posttreatment days 3 and 4 and 10-14. Fever on posttreatment days 3 and 4 was most commonly observed in patients treated with gemcitabine (20 %) or docetaxel (18 %). The causes of fever included infection (47 %; including febrile neutropenia [24 %]), adverse drug effects (24 %), unknown causes (19 %), and tumors (7 %). Radiotherapy led to a significant increase in the frequency of fever (46 vs. 34 %, p < 0.001). Thirty-three percent of patients received G-CSF, and the incidence ratios of fever in patients who received G-CSF were higher than those who did not receive G-CSF (44 vs. 31 %, p < 0.001). CONCLUSION The febrile episodes that occurred on posttreatment days 3 and 4 were considered to represent adverse drug reactions after cancer chemotherapy. Physicians should be aware of this feature of chemotherapy-associated fever and avoid unnecessary examination and treatments including prescribing antibiotics.
