This transition is due to advancements in refined anatomy, enlarged field of view, faster recovery, and comparable oncological outcomes. Several high-quality clinical studies have demonstrated the safety and effectiveness of laparoscopy in the treatment of both early and locally advanced gastric cancer. The role of perioperative chemotherapy in managing locally advanced gastric cancer has been widely recognized, and there have been continuous breakthroughs in the exploration of targeted therapy and immunotherapy for perioperative treatment. Additionally, the application of indocyanine green near-infrared imaging technology, 3D laparoscopic technology, and robotic surgery systems has further improved the accuracy and minimally invasive nature of gastric cancer surgeries. Looking ahead, the field of minimally invasive surgery for gastric cancer is expected to become more standardized, resulting in a significant enhancement in the quality of life for gastric cancer patients.展开更多

The cancer develops along a multistage process that is defined by distinct histological and pathophysiological phases. Several genetic and epigenetic alterations mediate the transition from one stage to another and these include mutations in oncogenes, tumour suppressor genes and cell cycle and mismatch repair genes. The most significant advance in the fight against gastric caner came with the recognition of the role of Helicobacter pylori (H pylori) as the most important acquired aetiological agent for this cancer. Recent work has focussed on elucidating the complex host/microbial interactions that underlie the neoplastic process. There is now considerable insight into the pathogenesis of this cancer and the prospect of preventing and eradicating the disease has become a reality. Perhaps more importantly, the study of H pylori-induced gastric carcinogenesis offers a paradigm for understanding more complex human cancers. In this review, we examine the molecular and cellular events that underlie Hpyloriinduced gastric cancer.展开更多

Since Stephen Paget first introduced the "seed and soil hypothesis" a century ago, growing evidence recognizes that numerous essential secreted factors and signaling pathway effectors participate in the pre-metastatic niche formation and distant organ metastasis. The cross-talk between GC cells and surrounding microenvironment may consist of a series of interrelated steps, including epithelial mesenchymal transition, intravasation into blood vessels, circulating tumor cell translocation, and secondary organ metastasis. Secreted factors including vascular endothelial growth factor(VEGF), matrix metalloproteinases and cancer-derived extracellular vesicles, especially exosomes, are essential in formation of premetastatic niche. Circulating tumor cells and micro RNAs represent as ‘‘metastatic intermediates' ' between primary tumors and sites of dissemination. Many biomarkers have been identified as novel metastatic markers and prognostic effectors. In addition, molecular therapy has been designed to target biomarkers such as growth factors(human epidermal growth factor receptor 2, VEGF) and chemokines, although they have not clearly proven to be effective in inhibiting GC metastasis in clinical trials. In this review, we will systematically discuss the emerging molecules and their microenvironment in hematogenous metastasis of GC, which may help us to find new therapeutic strategies in the future.展开更多

Most GC patients are diagnosed when the cancer is in an advanced stage, and consequently, some develop metastatic lesions that generally cause cancer-related death. Metastasis establishment is affected by various conditions, such as tumor location, hemodynamics and organotropism. While digestive cancers may share a primary site, certain cases develop hematogenous metastasis with the absence of peritoneal metastasis, and vice versa. Numerous studies have revealed the clinicopathological risk factors for hematogenous metastasis from GC, such as vascular invasion, advanced age, differentiation, Borrmann type 1 or 2 and expansive growth. Recently, molecular mechanisms that contribute to metastatic site determination have been elucidated by advanced molecular biological techniques. Investigating the molecules that specifically participate in metastasis establishment in distinct secondary organs will lead to the development of novel biomarkers for patient stratification according to their metastatic risk and strategies for preventing and treating distinct metastases. We reviewed articles related to the molecular landscape of hematogenous metastasis from GC.展开更多

Numerous studies have revealed the clinicopathological risk factors for hematogenous metastasis from GC, such as vascular invasion, advanced age, differentiation, Borrmann type 1 or 2 and expansive growth. Recently, molecular mechanisms that contribute to metastatic site determination have been elucidated by advanced molecular biological techniques. Investigating the molecules that specifically participate in metastasis establishment in distinct secondary organs will lead to the development of novel biomarkers for patient stratification according to their metastatic risk and strategies for preventing and treating distinct metastases. We reviewed articles related to the molecular landscape of hematogenous metastasis from GC.
文摘Long noncoding RNAs(lncRNAs)are important regulators of cell processes that are usually dysregulated in gastric cancer(GC).Based on their high specificity and ease of detection in tissues and body fluids,increasing attention has spurred the study of the roles of lncRNAs in GC patients.Thus,it is necessary to elucidate the molecular mechanisms and further explore the clinical applications of lncRNAs in GC.In this review,we summarize current knowledge to examine dysregulated lncRNAs in GC and their underlying molecular mechanisms and activities in GC,which involve microRNA sponging,mRNA stability,genetic variants,alternative splicing,transcription factor binding,and epigenetic modification.More significantly,the potential of lncRNAs as prognostic,circulating,and drug-resistant biomarkers for GC is also described.This review highlights the method of dissecting molecular mechanisms to explore the clinical application of lncRNAs in GC.Overall,this review offers assistance in using lncRNAs as novel candidates for molecular mechanisms and for the identification of revolutionary biomarkers for GC.

文摘BACKGROUND Gastric cancer(GC)is a highly heterogeneous disease,and the identification of molecular subtyping of gastric adenocarcinoma emerged as a promising option to define therapeutic strategies and prognostic subgroups.However,the costs and technical complexity of molecular methodologies remains an obstacle to its adoption,and their clinical significance by other approaches needs further evidence.AIM To evaluate the clinicopathological characteristics and long-term survival of GC based on the subgroups of molecular classification by immunohistochemistry(IHC)and in situ hybridization(ISH).METHODS We retrospectively evaluated all patients who underwent D2-gastrectomy between 2009 and 2016 in a Western cohort of GC patients treated with curative intent.Microsatellite instability(MSI)status,E-cadherin,and p53 expression were analyzed by IHC,and Epstein-Barr virus(EBV)by ISH.Tissue microarrays were constructed for analysis.Clinicopathological characteristics and survival of GC were evaluated according to subtypes defined by The Cancer Genome Atlas(TCGA)Research Network Group and Asian Cancer Research Group(ACRG)classification systems.RESULTS A total of 287 GC patients were included.Based on IHC and ISH analysis,five profiles were defined as follows:E-cadherin aberrant(9.1%),MSI(20.9%),p53 aberrant(36.6%),EBV positivity(10.5%),and p53 normal(31%),which corresponded to tumors that showed no alteration in another profile.A flowchart according to the TCGA and ACRG classifications were used to define the subtypes,where clinical and pathological characteristics associated with GC subtypes were evidenced.Proximal location(P<0.001),total gastrectomy(P=0.001),and intense inflammatory infiltrate(P<0.001)were characteristics related to EBV subtype.MSI subtype was predominantly associated with advanced age(P=0.017)and the presence of comorbidities(P=0.011).While Laurén diffuse type(P<0.001)and advanced stage(P=0.029)were related to genomically stable(GS)subtype.GS tumors and microsatellite stable/epithelial to mesenchymal transition phenotype subtype had worse disease-free survival(DFS)and overall survival(OS)than other subtypes.Conversely,MSI subtype of GC had better survival in both classifications.Type of gastrectomy,pT and the TCGA subtypes were independent factors associated to DFS and OS.CONCLUSION The IHC/ISH analysis was able to distinguish immunophenotypic groups of GC with distinct characteristics and prognosis,resembling the subtypes of the molecular classifications.Accordingly,this method of classification may represent a viable option for use in a clinical setting.

文摘Gastric cancer(GC)represents a leading cause of cancer related morbidity and mortality worldwide accounting for more than 1 million of newly diagnosed cases and thousands of deaths every year.In the last decade,the development of targeted therapies and the optimization of already available chemotherapeutic drugs has expanded the available treatment options for advanced GC and granted better survival expectations to the patients.At the same time,global efforts have been undertaken to investigate in detail the genomic and epigenomic heterogeneity of this disease,resulting in the identification of new specific and sensitive predictive and prognostic biomarkers and in innovative molecular classifications based on gene expression profiling.Nonetheless,several randomized studies aimed at exploring new innovative agents,such as immune checkpoint inhibitors,failed to demonstrate clinically meaningful survival advantages.Therefore,it is essential to further improve the molecular characterization of GC subgroups in order to provide researchers and medical oncologists with new tools for patients’selection and stratification in future clinical development programs and subsequent trials.The aim of the present manuscript is to provide a global overview of the recent molecular classifications from The Cancer Genome Atlas and the Asian Cancer Research Group and to present key promising developments in the field of immunotherapy and targeted therapies in metastatic GC.
