We propose to disclose first degree analogous features between cancer and infectious diseases and to find out whether these similarities are superficial and negligible, due to the use of the same bodily pathways by the two categories of disease or if they represent significantly parallel characteristics. We have found several primary analogous features, predominantly regarding pathways of spread, but to some extent also concerning the interaction with the immune system. Some of the implications to our hypothesis are probably available in the recent literature, at the experimental or clinical levels. For example endostatin, an angiogenic inhibitor has been used to prevent promotion of metastasis in cancer and to reduce granulomas formation in schistosomiasis. An ECFR antagonist employed to restrain bronchial vessels proliferation in pseudomonas infection, has also been used for the treatment of lung cancer.

The aim of this study was to evaluate the individual and combined diagnostic utility of vascular endothelial growth factor (VEGF) mRNA and endostatin mRNA in pleural effusions of patients with lung cancer. Transcription levels of VEGF and endostatin were detected by reverse transcription polymerase chain reaction (RT-PCR) in pleural effusions of patients with lung cancer (92 cases) and with lung benign disease (36 cases). Both VEGF mRNA and endostatin mRNA was significantly higher in malignant, AC, and SCC effusions than in benign effusions (P < 0.01). In the subgrouping, VEGF mRNA was obviously higher than endostatin mRNA in malignant and AC effusions (P < 0.01), whereas VEGF mRNA and endostatin mRNA did not differ between AC group and SCC group (P > 0.05). In single, VEGF mRNA had the highest sensitivity (82.6%) and accuracy (84.3%), whereas endostatin mRNA had the highest specificity (100%). When combinations of VEGF mRNA and endostatin mRNA were evaluated together, they gave a high-diagnostic performance: sensitivity of 95.7% and accuracy of 93.8%, respectively. The detection of VEGF mRNA and endostatin mRNA appears to be suitable for distinguishing carcinoma cells from reactive mesothelial cells in pleural effusions, they could be useful to diagnose the pleural micrometastasis.

Standard chemotherapy for advanced NSCLC has reached a therapeutic plateau. More effective strategies must be explored. The purpose of this study was to evaluate the role of metronomic chemotherapy combined with an angiogenesis inhibitor in non-small cell lung cancer (NSCLC). A total of 114 BALB/c nude mice were inoculated subcutaneously with human NSCLC cells (A549), and when xenograft tumors were palpable, mice were randomly injected with saline as controls (Ctrl), or treated with metronomic cyclophosphamide (MET CPA), recombinant human endostatin, Endostar (Endo), MET CPA combined with Endostar (MET CPA+Endo) or maximum tolerance dose of CPA (MTD CPA), respectively. The growth of xenograft tumors and mouse survival were monitored. The frequency of peripheral blood circulating endothelial cells (CECs), microvessel density (MVD) and pericyte coverage was determined using flow cytometry and immunofluorescence staining. In comparison with the controls, treatment with either drug significantly inhibited the growth of xenograft tumors in mice. Treatment with MET CPA or Endostar, but not with MTD CPA, significantly reduced the frequency of peripheral blood total and viable CECs and the value of MVD. Endostar also considerably reduced pericyte coverage in xenograft tumors. Moreover, MET CPA combined with Endostar further reduced the frequency of peripheral blood CECs, the value of MVD, and pericyte coverage, with concomitant delay in tumor growth and extension of mouse survival. Our results indicate that MET CPA combined with Endostar results in enhanced anti-tumor and anti-angiogenic effects in a xenograft model of human lung cancer. Combined therapy with metronomic chemotherapy and an angiogenesis inhibitor may serve as a promising treatment strategy for patients with advanced NSCLC.

Epigallocatechin 3-gallate (EGCG) has cytotoxic effects in many cancer cells. It has been reported that A549 lung cancer cells are markedly resistant to cell death induced by EGCG. In the present study, the effects of EGCG on A549 lung cancer cell growth and angiogenesis were studied. We found that EGCG dose-dependently suppressed A549 cell growth, while A549 cells were markedly resistant to cell death in vitro. Next we found that EGCG increased endostatin expression and suppressed vascular endothelial growth factor (VEGF) expression. We further studied to determine whether EGCG would suppress A549 tumor growth in nude mouse and angiogenesis. EGCG in drinking water significantly suppressed A549 tumor growth in nude mice. Histological analysis revealed that the number of CD34 positive vessels had a tendency to decrease in the tumor. In sum, EGCG had anti-proliferative effects of A549 on tumor growth and showed a tendency to suppress angiogenesis.

Lung cancer is the leading cause of cancer-related mortality in the United States. Over the past 40 years, treatments with standard chemotherapy agents have not resulted in substantial improvements in long-term survival for patients with advanced lung cancer. Therefore, new targets have been sought, and angiogenesis is a promising target for non-small cell lung cancer (NSCLC). Bevacizumab, a monoclonal antibody targeted against the vascular endothelial growth factor, is the only antiangiogenic agent currently recommended by NCCN for the treatment of advanced NSCLC. However, several antibody-based therapies and multitargeted tyrosine kinase inhibitors are currently under investigation for the treatment of patients with NSCLC. This article summarizes the available clinical trial data on the efficacy and safety of these agents in patients with advanced lung cancer.

Radiation therapy is a conventional strategy for treating advanced lung cancer yet is accompanied by serious side-effects. Its combination with other strategies, such as antiangiogenesis and gene therapy, has shown excellent prospects. As one of the potent endogenous vascular inhibitors, endostatin has been widely used in the antiangiogenic gene therapy of tumors. In the present study, LL/2 cells were infected with a recombinant adenovirus encoding endostatin (Ad-endostatin) to express endostatin. The results showed that LL/2 cells infected with the Ad-endostatin efficiently and longlastingly expressed endostatin. In order to further explore the role of Ad-endostatin combined with irradiation in the treatment of cancer, a murine lung cancer model was established and treated with Ad-endostatin combined with low-dose irradiation. The results showed that the combination treatment markedly inhibited tumor growth and metastasis, and prolonged the survival time of the tumor-bearing mice. Furthermore, this significant antitumor activity was associated with lower levels of microvessel density and anoxia factors in the Ad-Endo combined with irradiation group, and with an increased apoptotic index of tumor cells. In addition, no serious side-effects were noted in the combination group. Based on our findings, Ad-endostatin combined with low-dose irradiation may be a rational alternative treatment for lung cancer and other solid tumors.

This retrospective study was conducted to determine whether endostatin improves the efficacy and safety of platinum-based chemotherapy administered via both intravenous and arterial infusions for stage III/IV non-small-cell lung cancer (NSCLC). Seventy one patients with confirmed pathological or cytological diagnosis of NSCLC from January 2008 to March 2013 were enrolled for the study. Patients received three different therapeutic regimens until disease progression or an intolerable toxicity was evidenced. Group C received chemotherapy administered by intravenous injection and subsequent radiotherapy. Group IC received chemotherapy by intravenous injection and arterial infusion plus radiotherapy. Group IC + E patients were treated with chemotherapy plus Endostatin injected arterially and intravenously and subsequent radiotherapy. Group IC + E showed a progression-free survival (PFS) of 12 months as compared to 7 months of group C, a significant increase indeed (p = 0.037). Likewise, the overall survival time higher in Group IC + E and Group IC was compared to Group C (p = 0.001; p = 0.004, respectively). The adverse or toxic side effects exhibited by Group IC + E were not significantly different from either Group IC or Group C. Endostatin administered in combination with chemotherapeutic agents via both intravenous injection and arterial infusion enhanced the PFS and OS in advanced NSCLC without increasing the risk of toxicity.

Brain metastases (BM) heavily affects the prognosis of advanced non-small cell lung cancer (NSCLC). Although whole-brain radiotherapy remains the mainstream therapy for BM caused by NSCLC, the effectiveness is unsatisfactory. Endostar, a recombinant human endostatin (RHES), has shown certain therapeutic effect on advanced NSCLC. This article reviews the feasibility of Endostar combined with radiotherapy in the treatment of BM caused by NSCLC.

Our previous study suggests that heme oxygenase-1 (HO-1) may play an important role in the metastasis of gastric cancer. Zinc protoporphyrin IX (ZnPPIX) is a special HO-1 inhibitor that inhibits the angiogenesis of pancreatic and lung cancer. In this study, we employed ZnPPIX to investigate the role of HO-1 in peritoneal metastasis of gastric cancer (PMGC) and explored the potential mechanism. We established animal model of PMGC by orthotopic implantation into nude mice of human gastric cancer cell line GC9811-P with high peritoneal metastasis potential. The mice were injected intraperitoneally with saline, CTX or ZnPPIX. Tumor microvessel density (MVD) in peritoneal metastatic nodules was determined by immunohistochemistry, and vascular endothelial growth factor (VEGF) level was determined by ELISA. We found that the number, volume, weight of peritoneal metastatic nodules and volume of seroperitoneum in ZnPPIX (4 mg/kg) group decreased remarkably compared with control group. MVD value and VEGF level of peritoneal metastatic tumor in ZnPPIX (4 mg/kg) group also decreased significantly, while the survival rate and survival time of the mice were higher than control group. ZnPPIX dose-dependently suppressed VEGF and GC9811-P induced angiogenesis. Furthermore, ZnPPIX suppressed VEGF induced reactive oxygen species production and ERK phosphorylation in human umbilical vein endothelial cells. In conclusion, our results suggest that HO-1 plays an important role in PMGC and ZnPPIX is an effective antitumor and antiangiogenic agent for PMGC.

Lung cancer encompasses a diverse spectrum of histologic subtypes. Until recently, the majority of therapeutic advances were limited to the minority of patients with adenocarcinoma. With the advent of comprehensive genomic profiling of squamous and small cell lung cancers, new therapeutic targets have emerged. For squamous tumors, the most promising of these include fibroblast growth factor receptor (FGFR), the phosphatidylinositol 3-kinase (PI3K) pathway, discoidin domain receptor 2 (DDR2), and G1/S checkpoint regulators. In 2014, the antiangiogenic agent ramucirumab was approved for all non-small cell lung cancer (NSCLC) histologies, including squamous tumors. Immunotherapeutic approaches also appear to be promising for these cases. Genomic analysis of small cell lung cancer has revealed a high mutation burden, but relatively few druggable driver oncogenic alterations. Current treatment strategies under investigation are focusing on targeting mitotic, cell cycle, and DNA repair regulation, as well as immunotherapy. Pulmonary neuroendocrine tumors represent a diverse spectrum of diseases that may be treated with somatostatin analogs, cytotoxic agents, and molecularly targeted therapies. Radiolabeled somatostatin analogs and combinations with mammalian target of rapamycin (mTOR) inhibitors also show potential. Large cell neuroendocrine tumors share numerous clinical, pathologic, and molecular features with small cell lung cancer; however, whether they should be treated similarly or according to a NSCLC paradigm remains a matter of debate.
