Abstract
Cancer cells circulating in the blood attach to platelets by direct cell-cell interactions via several receptor-counterreceptor contacts and indirectly by fibrin bridges which connect the two cell types by distinct integrin receptors. In the microenvironment of these tumor cell platelet aggregates (TCPAs), the tumor cells are shielded from the shear stress of the blood flow and from attack by the immune system. This supports hematogenous metastasis and tumor cell induced thrombosis. Platelet activation is triggered by binding of podoplanin on cancer cells to the platelet receptor Clec-2. Therefore, we hypothesize that targeting this initial step will prevent the entire cascade leading to the formation of TCPAs. Rhodocytin, a heterodimeric (αβ)2 C-type lectin from the Malayan pit viper Calloselasma rhodostoma, binds to Clec-2 and thereby induces TCPA formation. Remarkably, mutations in rhodocytin that disturbed formation of oligomers, blocked the podoplanin-Clec-2 axis and prevented platelet activation. Therefore, we used lysine reactive chemicals to modify rhodocytin isolated from the crude snake venom. Blue native gel electrophoresis and far western blotting showed a change of rhodocytin's suprastructure triggered by acetylation and PEGylation. Mass spectrometry analysis of altered lysines suggested that their modifications interfered with the formation of rhodocytin tetramers. When tested in assays for tumor cell induced platelet aggregation, we found that derivatization turned rhodocytin from an agonist into an antagonist. This observation indicates that Clec-2 is a valid target receptor molecule to curb TCPA formation and to prevent hematogenous metastasis and tumor cell induced thrombosis in cancer patients.

Abstract
The assessment of molecular genetic landscape changes during NAC and the relationship between molecular signatures in residual tumors are promising approaches for identifying effective markers of outcome in breast cancer. The majority of the data in the literature present the relationship between the molecular genetic landscape and the response to NAC or are simply descriptive. The present study aimed to determine changes in expression profiles during NAC and assess the relationship between gene expression and the outcome of patients with luminal B HER2 breast cancer depending on distant hematogenous metastasis. The study included 39 patients with luminal B HER2-BC. The patients received 6-8 courses of NAC, and paired samples consisting of biopsy and surgical materials were analyzed. A full transcriptome microarray analysis was performed using the human Clariom™ S Assay platform (Affymetrix, 3450 Central Expy, Santa Clara, CA, 95051, USA). A comparison of the expression profiles of patients with breast cancer before and after NAC, depending on the status of hematogenous metastasis, was conducted. It was shown that the amount of DEGs in the tumor was reduced by more than six times after NAC. The top 10 signaling pathways were also found, the activity of which varied depending on the status of hematogenous metastasis before and after NAC. In addition, the association of DEGs with hematogenous metastasis in patients with breast cancer was evaluated: MFS was assessed depending on the expression level of 21 genes. It was shown that MFS was significantly associated with the expression level and pattern of nine genes. The expression levels of nine DEGs in the tumors of patients with breast cancer after NAC were significantly correlated with MFS when the status of hematogenous metastasis was taken into account.

Abstract
The aim of the present study was to assess the influence of localization, age or sex and histopathological characteristics upon the chance of developing lymphatic or hematogenous metastatic spread over time, or a positive sentinel lymph node in cutaneous melanoma patients. Patients from the Department of Dermatology, County Emergency Hospital Cluj-Napoca (Cluj-Napoca, Romania), presenting with cutaneous melanoma confirmed histopathologically and a SPECT/CT or lymphoscintigraphic examination to detect the sentinel lymph node, were included in the present study. Our results revealed that Breslow index >2 mm [odds ratio (OR)=4.22, 95% confidence interval (CI) (1.12; 15.93)], presence of ulceration [OR=6.01, 95% CI (1.87; 19.35)], and positive sentinel lymph node [for at least one sentinel lymph node OR=3.58, 95% CI (1.06; 12.04)] were risk factors for hematogenous metastases. All these, except for the Breslow index >2 mm, were demonstrated to be a risk factor for lymphatic spread metastases over time. Ulceration and male sex also represented risk factors for a positive sentinel lymph node, men having a higher risk of developing sentinel lymph nodes than women [adjusted OR=2.27, 95% CI (1.00; 5.13)]. In conclusion, the predictors that influence the occurrence of lymphatic or hematogenous metastases may differ, ulceration and positive sentinel lymph node being common for both types of metastatic spread, while Breslow index being a significant predictor only for hematogenous metastases. Male sex and the presence of ulceration were demonstrated to be significant risk factors for positive sentinel lymph nodes.

Abstract
Tumor-associated macrophages (TAMs) are major innate immune cells that constitute up to 50% of the cell mass of human tumors. TAMs are highly heterogeneous cells that originate from resident tissue-specific macrophages and from newly recruited monocytes. TAMs’ variability strongly depends on cancer type, stage, and intratumor heterogeneity. Majority of TAMs are programmed by tumor microenvironment to support primary tumor growth and metastatic spread. However, TAMs can also restrict tumor growth and metastasis. In this review, we summarized the knowledge about the role of TAMs in tumor growth, metastasis and in the response to cancer therapy in patients with five aggressive types of cancer: breast, colorectal, lung, ovarian, and prostate cancers that are frequently metastasize into distant organs resulting in high mortality of the patients. Two major TAM parameters are applied for the evaluation of TAM correlation with the cancer progression: total amount of TAMs and specific phenotype of TAMs identified by functional biomarkers. We summarized the data generated in the wide range of international patient cohorts on the correlation of TAMs with clinical and pathological parameters of tumor progression including lymphatic and hematogenous metastasis, recurrence, survival, therapy efficiency. We described currently available biomarkers for TAMs that can be measured in patients’ samples (tumor tissue and blood). CD68 is the major biomarker for the quantification of total TAM amounts, while transmembrane receptors (stabilin-1, CD163, CD206, CD204, MARCO) and secreted chitinase-like proteins (YKL-39, YKL-40) are used as biomarkers for the functional TAM polarization. We also considered that specific role of TAMs in tumor progression can depend on the localization in the intratumoral compartments. We have made the conclusion for the role of TAMs in primary tumor growth, metastasis, and therapy sensitivity for breast, colorectal, lung, ovarian, and prostate cancers. In contrast to other cancer types, majority of clinical studies indicate that TAMs in colorectal cancer have protective role for the patient and interfere with primary tumor growth and metastasis. The accumulated data are essential for using TAMs as biomarkers and therapeutic targets to develop cancer-specific immunotherapy and to design efficient combinations of traditional therapy and new immunomodulatory approaches.

Abstract
BACKGROUND/AIM Few studies have studied micro hepatic vein invasion in hepatocellular carcinoma (HCC). We explored the correlation between hepatic vein invasion and hepatitis B/C virus infection. PATIENTS AND METHODS Between April 2000 and February 2018, 869 patients underwent liver resection for HCC at a single center. The patients were divided into two groups: those with micro hepatic vein invasion (VV+) and those without (VV-). The clinical data, overall survival (OS) and correlations with the presence of hepatitis B and C viruses were investigated. RESULTS There were 817 VV- patients and 43 VV+ patients. OS was 66.2 months for VV- patients and 9.9 months for VV+ patients (p=0.0010). VV+ patients had significantly higher levels of serum HBV DNA (p=0.016). CONCLUSION HCC patients with micro hepatic vein invasion showed significantly shorter OS. A higher level of HBV DNA appears to be a risk factor for micro hepatic vein invasion.

Abstract
Although metastasis is the primary cause of death in patients with malignant solid tumors, efficient anti-metastatic therapies are not clinically available currently. Sulfated glycosaminoglycans from marine sources have shown promising pharmacological effects, acting on different steps of the metastatic process. Oversulfated dermatan sulfates from ascidians are effective in preventing metastasis by inhibition of P-selectin, a platelet surface protein involved in the platelet-tumor cell emboli formation. We report in this work that the heparan sulfate isolated from the viscera of the ascidian Phallusia nigra drastically attenuates metastases of colon carcinoma cells in mice. Our in vitro and in vivo assessments demonstrate that the P. nigra glycan has very low anticoagulant and antithrombotic activities and a reduced hypotension potential, although it efficiently prevented metastasis. Therefore, it may be a promising candidate for the development of a novel anti-metastatic drug.

Abstract
BACKGROUND/AIM Uterine leiomyosarcoma (Ut-LMS) is a refractory tumor that repeatedly recurs with hematogenous metastasis, which may be due to the presence of drug-resistant tumor stem cells. Its treatment is limited to surgical procedures. We previously reported that Ut-LMS spontaneously developed in mice deficient in the proteasome component low-molecular mass polypeptide 2 (LMP2). We showed that LMP2 expression was significantly attenuated specifically in human Ut-LMS. The aim of this study was to investigate the role of LMP2 in hematogenous metastasis using xenograft models with tumor stem-like cells. MATERIALS AND METHODS We isolated tumor stem-like cells from LMP2-negative primary human Ut-LMS cells established from a human Ut-LMS tissue using the side population (SP) procedure. These cells were used to develop xenograft models with tumor stem-like cells. RESULTS Human Ut-LMS stem-like cells showed stronger hematogenous metastatic potential than normal Ut-LMS cells. Tumor stem-like cells also had the potential to differentiate into vascular endothelial cells through VEGF-A signaling. CONCLUSION These results reflect frequent hematogenous metastasis by human Ut-LMS in clinical settings, and may lead to the development of treatments that inhibit hematogenous metastasis in Ut-LMS.

Abstract
Tumor-associated macrophages (TAMs) that appear in every stage of cancer progression are usually tumor-promoting cells and are present abundantly in the tumor-associated microenvironment. In ovarian cancer, the overall and intratumoral M1/M2 ratio is a relatively efficient TAM parameter for predicting the prognosis of patients, especially for serous tissue type cancer. TAMs exhibit immunological checkpoint modulators, such as the B7 family and programmed death-ligand 1 (PD-L1), and play a key role in the development, metastasis and invasion of ovarian cancer, but the underlying mechanism is barely understood. Ovarian cancer is a severe gynecological malignancy with high mortality. Ovarian cancer-associated death can primarily be attributed to cancer metastasis. The majority of patients are diagnosed with wide dissemination in the peritoneum and omentum, limiting the effectiveness of surgery and chemotherapy. In addition, unlike other well-documented cancers, metastasis through vasculature is not a usual dissemination pathway in ovarian cancer. This review sheds light on TAMs and the main process and mechanism of ovarian cancer metastasis.

Abstract
BACKGROUND/AIM The clinicopathological significance and prognostic value of insulin-like growth factor binding protein 1 (IGFBP1) in gastric cancer have not been investigated to date. This study aimed to investigate the relationship of IGFBP1 expression with clinicopathological variables and prognosis. MATERIALS AND METHODS The correlation of IGFBP1 expression with the clinicopathological factors and the correlation of clinicopathogical factors with haematogenous metastasis in 219 gastric cancer patients who underwent surgery was examined. RESULTS High IGFBP1 expression was significantly associated with a poorer disease-specific survival (p<0.001) and relapse-free survival (p<0.001) in univariable analysis although IGFBP1 was not an independent prognostic factor. High IGFBP1 expression was the only independent risk factor of haematogenous metastasis. CONCLUSION High IGFBP1 expression was associated with haematogenous metastasis and poor survival. IGFBP1 might become a new prognostic factor and a target of molecular targeted therapy of gastric cancer.

Abstract
Snake venoms contain an astounding variety of different proteins. Among them are numerous C-type lectin family members, which are grouped into classical Ca2+- and sugar-binding lectins and the non-sugar-binding snake venom C-type lectin-related proteins (SV-CLRPs), also called snaclecs. Both groups share the robust C-type lectin domain (CTLD) fold but differ in a long loop, which either contributes to a sugar-binding site or is expanded into a loop-swapping heterodimerization domain between two CLRP subunits. Most C-type lectin (-related) proteins assemble in ordered supramolecular complexes with a high versatility of subunit numbers and geometric arrays. Similarly versatile is their ability to inhibit or block their target molecules as well as to agonistically stimulate or antagonistically blunt a cellular reaction triggered by their target receptor. By utilizing distinct interaction sites differentially, SV-CLRPs target a plethora of molecules, such as distinct coagulation factors and receptors of platelets and endothelial cells that are involved in hemostasis, thrombus formation, inflammation and hematogenous metastasis. Because of their robust structure and their high affinity towards their clinically relevant targets, SV-CLRPs are and will potentially be valuable prototypes to develop new diagnostic and therapeutic tools in medicine, provided that the molecular mechanisms underlying their versatility are disclosed.

Abstract
Leptomeningeal dissemination (LMD) is the defining pattern of metastasis for medulloblastoma. Although LMD is responsible for virtually 100% of medulloblastoma deaths, it remains the least well-understood part of medulloblastoma pathogenesis. The fact that medulloblastomas rarely metastasize outside the CNS but rather spread almost exclusively to the spinal and intracranial leptomeninges has fostered the long-held belief that medulloblastoma cells spread directly through the CSF, not the bloodstream. In this paper the authors discuss selected molecules for which experimental evidence explains how the effects of each molecule on cell physiology contribute mechanistically to LMD. A model of medulloblastoma LMD is described, analogous to the invasion-metastasis cascade of hematogenous metastasis of carcinomas. The LMD cascade is based on the molecular themes that 1) transcription factors launch cell programs that mediate cell motility and invasiveness and maintain tumor cells in a stem-like state; 2) disseminating medulloblastoma cells escape multiple death threats by subverting apoptosis; and 3) inflammatory chemokine signaling promotes LMD by creating an oncogenic microenvironment. The authors also review recent experimental evidence that challenges the belief that CSF spread is the sole mechanism of LMD and reveal an alternative scheme in which medulloblastoma cells can enter the bloodstream and subsequently home to the leptomeninges.

Abstract
Goals This study aimed to summarize the clinicopathological data of the cases of gastric cancer or colon cancer with regular metastasis in the mesentery of small intestine and explore the pathway of peritoneal carcinomatosis. Materials and methods We retrospectively analyzed 5 cases of gastric cancer and 3 cases of colon cancer with regular metastasis in the mesentery of the small intestine from January 2014 to June 2016, including clinical information, gross manifestations during operation, treatment, and pathology. Results The clinical characteristics of all 8 cases were fully collected. The symptoms were various without specificity. All patients were found to present with metastasis in peritoneum during operation and the metastatic lesions arranged along the blood vessels orderly. The metastatic lesions of all studied patients were proved to be malignant carcinoma histopathologically, the same as the original tumor. Tumor emboli were seen in the vessel and invasive neoplastic foci was also seen in the vascular wall. Conclusions The traditional view that peritoneal carcinomatosis is due to seeding has no sufficient basis. Hematogenous metastasis maybe the real way of peritoneal carcinomatosis combined with clinical presentation.

Abstract
Metastasis is the primary cause of death for most cancer patients. Hematogenous arrest of circulating tumor cells (CTCs) is an essential prerequisite for metastases formation. Using transparent transgenic zebrafish (kdrl:eGFP; Casper), together with resonant laser scanning confocal microscopy, we tracked the fate of CTCs in vivo in the blood circulation for days. We found the intra-capillary morphology-switch (ICMS) of individual CTCs from strip to sphere was necessary for their intravascular arrests. Further genetic and pharmacological inhibition experiments indicated that the RhoA signaling was necessary for ICMS and the arrest of CTCs. At last, we demonstrated that early treatment by a clinically approved RhoA/ROCK inhibitor, Fasudil, could efficiently inhibit the initial arrest of individual CTCs and reduce the incidence of tumor metastasis in both zebrafish and mouse models. These results together indicate that RhoA-stimulated ICMS represents a mechanism for the arrest of individual CTCs, providing a potential target for future treatments of hematogenous metastatic disease.

Abstract
We, along with others, have shown previously that P21-activated kinase 1 (Pak1) plays a pivotal role in gastric cancer progression and metastasis. However, whether Pak1 controls gastric cancer metastasis by regulating microRNAs (miRNAs) has never been explored. Here, we report a novel mechanism of Pak1 in tumor metastasis. A detailed examination revealed that Pak1 interacts with and phosphorylates the serine 62 residue of ATF2 and then blocks its translocation into the nucleus. We also confirmed that ATF2 binds to the promoter of miR-132 and tightly regulates its transcription, thus explaining the regulatory mechanism of miR-132 by Pak1. miR-132 also significantly reduced cell adhesion, migration, and invasion of gastric cancer cells in vitro and significantly prevented tumor metastasis in vivo. miR-132 specifically inhibited hematogenous metastasis, but not lymph node or implantation metastases. In order to further delineate the effects of the Pak1/ATF2/miR-132 cascade on gastric cancer progression, we identified several targets of miR-132 using a bioinformatics TargetScan algorithm. Notably, miR-132 reduced the expression of CD44 and fibronectin1 (FN1), and such inhibition enabled lymphocytes to home in on gastric cancer cells and induce tumor apoptosis. Taken together, our studies establish a novel cell-signaling pathway and open new possibilities for therapeutic intervention of gastric cancer.

Abstract
Pancreatic ductal carcinoma (PDC) is one of the major causes of cancer-associated mortality globally due to its high potential for distant metastasis. To understand hematogenous metastasis, the molecular expression profiles of weak metastatic PDC cell subline BxPC-3 and highly liver-metastatic cell subline LM-BxPC-3 were compared, and zinc finger protein 185 (ZNF185) was identified as a molecule that is upregulated in LM-BxPC-3 cells. The aim of the present study was to evaluate the clinicopathological significance of ZNF185 in PDC. Using immunohistochemistry, ZNF185 expression was investigated in 182 patients with PDC, in association with numerous clinicopathological variables. The expression profile of ZNF185 was also characterized using xenograft models. In contrast to parent BxPC-3 cells in subcutaneous transplanted tumor foci, which only expressed ZNF185 on their plasma membrane (m)ZNF185, LM-BxPC-3 cells in liver-metastatic foci that were formed subsequent to transplantation all expressed cytoplasmic (c)ZNF185. Additionally, 51% of the cells at the periphery of the tumor foci expressed mZNF185. Expression of cZNF185, and of mZNF185 and cZNF185 combined was identified in 93 and 39% of clinical patients with PDC, respectively. Patients with mZNF185-negative and -positive PDC exhibited a median survival time of 30.2 months and 21.3 months, respectively. Multivariate analysis indicated that the expression of mZNF185 is closely associated with a shorter overall survival time. Increased marked venous invasion was more prevalent in patients who were mZNF185-positive, as compared with patients who were mZNF185-negative. These data suggest that the expression of mZNF185 is an independent and unfavorable prognosticator in patients with PDC. The results suggested that the amount and subcellular location of ZNF185 are correlated with the position of the cancer cells expressing it within the nests. Additionally, the subcellular location of ZNF185 may be important to its biological function.

Abstract
Pulmonary endometriosis (PEM) is a rare disease characterized by the proliferation of ectopic endometrial tissue in the lungs, which presents as catamenial hemoptysis. A 20-year-old-woman was admitted for repeated hemoptysis. Chest CT revealed a ground-glass opacity that appeared consistently with her menstrual cycle. Our detailed inquiry revealed a history of artificial abortion, which was followed by the use of oral contraceptives and catamenial hemoptysis after the discontinuation of these medications. Surgical removal was performed and histopathological examinations confirmed PEM. This clinical course suggested hematogenous metastasis. An inquiry regarding the patient's history of uterine procedures and use of oral contraceptives was suggestive for the diagnosis of this disease.

Abstract
Chest wall tumors are relatively rare, and hematogenous metastasis to the chest wall is very rare. We herein describe a rare case of occult thyroid carcinoma as metastasis to the chest wall in an 80-year-old woman. The patient received detailed examinations of the chest wall tumor, and the results suggested that she had occult thyroid carcinoma. Surgery was then performed to remove all of her thyroid. As a result, she was diagnosed with follicular carcinoma of the thyroid. We report an extremely rare case of occult thyroid carcinoma diagnosed as hematogenous metastasis to the chest wall.

Abstract
The molecular mechanisms orchestrating peritoneal and hematogenous metastases of ovarian cancer cells are assumed to be distinct. We studied the p90RSK family of serine/threonine kinases that lie downstream the RAS-ERK/MAPK pathway and modulate a variety of cellular processes including cell proliferation, survival, motility and invasiveness. We found the RSK1 and RSK2 isoforms expressed in a number of human ovarian cancer cell lines, where they played redundant roles in sustaining in vitro motility and invasiveness. In vivo, silencing of both RSK1 and RSK2 almost abrogated short-term and long-term metastatic engraftment of ovarian cancer cells in the peritoneum. In addition, RSK1/RSK2 silenced cells failed to colonize the lungs after intravenous injection and to form hematogenous metastasis from subcutaneous xenografts. RSK1/RSK2 suppression resulted in lessened ovarian cancer cell spreading on endogenous fibronectin (FN). Mechanistically, RSK1/RSK2 knockdown diminished FN transcription, α5β1 integrin activation and TGF-β1 translation. Reduced endogenous FN deposition and TGF-β1 secretion depended on the lack of activating phosphorylation of the transcription/translation factor YB-1 by p90RSK. Altogether data show how p90RSK activates a self-reinforcing cell autonomous pro-adhesive circuit necessary for metastatic seeding of ovarian cancer cells. Thus, p90RSK inhibitors might hinder both the hematogenous and the peritoneal metastatic spread of human ovarian cancer.

Abstract
Kindlin‐2 is involved in activating the integrin signaling pathway which plays an important role in regulating cancer cell invasion. However, the role of kindlin‐2 may vary among cancer types. The aim of this study was to explore the possible association between kindlin‐2 and clear cell renal cell carcinoma (ccRCC), and its potential role in the prognosis of ccRCC. Immunohistochemistry assays were used to examine kindlin‐2 expression levels in cancer tissues obtained from 336 patients with ccRCC. The correlation between kindlin‐2 expression levels and pathologic variables was then analyzed. In addition, the association between kindlin‐2 expression levels and survival time was analyzed by Kaplan–Meier survival curves and log‐rank tests. Of 336 ccRCC patients, 199 had high levels of kindlin‐2 expression, while 137 had low kindlin‐2 expression levels. Patients at a late stage of ccRCC (stage III or IV) were more likely to have high kindlin‐2 expression levels than those at an early stage (stage I or II) (χ2 = 4.72, P = 0.03). Patients with high levels of kindlin‐2 expression had higher risk of hematogenous metastasis (χ2 = 6.70, P = 0.01) than those with low levels of kindlin‐2 expression. In addition, the survival time was significantly shorter for patients with high levels of kindlin‐2 expression than for those with low levels of kindlin‐2 expression (P = 0.001 for overall survival [OS] and P = 0.002 for disease‐free survival [DFS]). Multivariate survival analysis based on the Cox proportional hazards model showed that high kindlin‐2 expression levels had a hazard risk (HR) of 1.76 for OS (95% CI 1.19–2.62, P = 0.005) and an HR of 1.47 for DFS (95% CI = 1.05–2.06, P = 0.026). By comparison, lymph node metastasis had an HR of 1.48 for OS (95% CI 1.04–2.10, P = 0.029) and an HR of 1.41 for DFS (95% CI 1.04–1.93, P = 0.029). This study provided strong evidence that increased kindlin‐2 expression might be involved in promoting tumor invasiveness and leading to a poor prognosis of ccRCC.

Abstract
Ovarian cancer is the most lethal gynecological malignancy. It is usually diagnosed at a late stage, with a 5-yr survival rate of <30%. The majority of ovarian cancer cases are diagnosed after tumors have widely spread within the peritoneal cavity, limiting the effectiveness of debulking surgery and chemotherapy. Owing to a substantially lower survival rate at late stages of disease than at earlier stages, the major cause of ovarian cancer deaths is believed to be therapy-resistant metastasis. Although metastasis plays a crucial role in promoting ovarian tumor progression and decreasing patient survival rates, the underlying mechanisms of ovarian cancer spread have yet to be thoroughly explored. For many years, researchers have believed that ovarian cancer metastasizes via a passive mechanism by which ovarian cancer cells are shed from the primary tumor and carried by the physiological movement of peritoneal fluid to the peritoneum and omentum. However, the recent discovery of hematogenous metastasis of ovarian cancer to the omentum via circulating tumor cells instigated rethinking of the mode of ovarian cancer metastasis and the importance of the "seed-and-soil" hypothesis for ovarian cancer metastasis. In this review we discuss the possible mechanisms by which ovarian cancer cells metastasize from the primary tumor to the omentum, the cross-talk signaling events between ovarian cancer cells and various stromal cells that play crucial roles in ovarian cancer metastasis, and the possible clinical implications of these findings in the management of this deadly, highly metastatic disease.

Abstract
Metastatic cancer cells are lethal. Understanding the molecular mechanisms that bolster the conversion from benign to malignant progression is key for treating these heterogeneous and resistant neoplasms. The epithelial-mesenchymal transition (EMT) is a conserved cellular program that alters cell shape, adhesion and movement. The shift to a more mesenchymal-like phenotype can promote tumor cell intravasation of surrounding blood vessels and emigration to a new organ, yet may not be necessary for extravasation or colonization into that environment. Lymphatic dissemination, on the other hand, may not require EMT. This review presents emerging data on the modes by which tumor cells promote EMT/MET via microRNA and prepare the pre-metastatic niche via exosomes.

Abstract
The expression of CD44 variant containing variant exons 8-10 product (CD44v8-10) was studied by western blot analysis and immunohistochemistry in gastric cancers using a monoclonal antibody, 44-1V. On western blots, a single band of 130 kD was recognized in stomach cancer cell lines. CD44v8-10 expression, with reactivity localized in the cell membrane, was found in 65 (33.5%) of the 194 advanced gastric cancers. There was no correlation between CD44v8-10 immunoreactivity and serosal, lymphatic, or lymph node invasion. However, there was significant correlation with CD44v8-10 immunoreactivity and venous invasion. CD44v8-10-positive cancers were more frequently associated with hematogenous metastasis than those which were immunonegative. There was an inverse association between CD44v8-10 immunoreactivity and peritoneal dissemination, especially in diffuse type adenocarcinomas. These observations indicate that CD44v8-10 may play a role in the metastasis of gastric cancer.
