Abstract
Paclitaxel (PTX), especially albumin-bound PTX in clinical, has displayed significant inhibition of tumor growth in patients. But the systemic distribution and poor water solubility of PTX often lead to severe side effects, consequently limiting the anti-tumor efficacy. In this study, we developed a novel PTX-loaded polymeric micelle drug delivery system. These self-assembled polymeric micelles from core to outside consisted of poly L-phenylalanine (pPhe), DTSSP linked poly L-lysine (pLys), poly ethylene glycol (PEG) and dehydroascorbic acids (DHA). pPhe formed the hydrophobic core to encapsulate PTX; DTSSPs on pLys covalently cross-linked and formed disulfide bond to stabilize PTX from loss in blood circulation; PEG improved solubility to lower toxicity of PTX for its high hydrophilicity; DHA targeted tumors by specifically recognizing GLUT1 mainly expressed on tumor cells. Thus, PTX would be precisely released into tumor cells with high dose of glutathione to break disulfide bond. Moreover, these PTX-loaded polymer micelles significantly suppressed tumor cell viability, proliferation, and migration in vitro, and also greatly inhibited tumor growth and prolonged survival in tumor-bearing mice without detectable side effects. Therefore, the new drug delivery system could reduce severe side effects and enhance anti-tumor efficacy of PTX via peripheral stabilization, low toxicity and tumor targeting.

Abstract
Angiogenesis is a key process in cancer development. We performed a meta-analysis to assess the efficacy and safety of the novel VEGFR-2 inhibitors in patients with metastatic gastric and gastroesophageal junction cancer. A literature-based meta-analysis of randomized controlled trials (RCTs) was undertaken. The primary outcome was the overall survival. The pooled analysis from RCTs on anti-VEGFR-2 inhibitors revealed a significant increase in overall survival (hazard ratio for death: 0.69, 95% confidence interval: 0.55-0.87; p = .002). This study confirms the efficacy of novel anti-VEGFR-2 inhibitors. The future studies of these agents will evaluate alone and in combination with chemotherapy the early line of treatment along with the identification of proper predictive biomarker.

Abstract
The characterization of oesophageal and gastric cancer into subtypes based on genotype has evolved in the past decade. Insights into the molecular landscapes of gastroesophageal cancer provide a roadmap to assist the development of new drugs and their use in combinations, for patient stratification, and for trials of targeted therapies. Trastuzumab is the only approved treatment for gastroesophageal cancers that overexpress HER2. Acquired resistance usually limits the duration of response to this treatment, although a number of new agents directed against HER2 have the potential to overcome or prolong the time until resistance occurs. Beyond that, anti-VEGFR2 therapy with ramucirumab was the first biological treatment strategy to produce a survival benefit in an unselected population of patients with chemotherapy-refractory gastroesophageal cancer. Large initiatives are starting to address the role of biomarker-driven targeted therapy in the metastatic and in the perioperative setting for patients with this disease. Immunotherapy also holds promise, and our understanding of subsets of gastroesophageal cancer based on patterns of immune response continues to evolve. Efforts are underway to identify more relevant genomic subsets through genomic screening, functional studies, and molecular characterization. Herein, we provide an overview of the key developments in the treatment of gastroesophageal cancer, and discuss potential strategies to further optimize therapy by targeting disease subtypes.

Abstract
Despite significant improvements in systemic chemotherapy during the past two decades, the prognosis of patients with advanced gastric and gastroesophageal junction adenocarcinoma remains poor. Because of molecular heterogeneity, it is essential to classify tumors based on the underlying oncogenic pathways and to develop targeted therapies acting on individual tumors. Unfortunately, although a number of molecular targets have been studied, very few of these agents can be used in a clinical setting. In this review, we summarize the available data on anti-angiogenic agents in advanced/metastatic gastric cancer.

Abstract
Ramucirumab (Cyramza(®)), an intravenously administered, monoclonal antibody against vascular endothelial growth factor receptor-2, is approved in the USA, EU and Japan (either as a single agent or in combination with paclitaxel) as second-line treatment in adults with advanced gastric or gastro-oesophageal junction adenocarcinoma. In two phase III trials (REGARD and RAINBOW) in this indication, overall survival and progression-free survival were significantly prolonged with ramucirumab 8 mg/kg every 2 weeks compared with placebo, and with ramucirumab 8 mg/kg every 2 weeks plus weekly paclitaxel compared with placebo plus paclitaxel. Ramucirumab had a generally acceptable tolerability profile in phase III trials; hypertension was the most common non-haematological adverse event of grade 3 or higher with ramucirumab (either alone or with paclitaxel). As the first antiangiogenic agent to provide significant survival benefit in patients with advanced gastric cancer, ramucirumab is a valuable option in the second-line treatment of advanced gastric or gastro-oesophageal junction adenocarcinoma.
