DESCRIPTION (provided by applicant): Over the last decade it has become increasingly recognized that non-malignant components of a tumor, called the tumor microenvironment (TME), play a major contributor role in cancer development and progression 1-4. This heterotypic view of cancer recognizes that tumor cells which may not be intrinsically able to disseminate or to resist therapeutic insults, can acquire these properties as the result of specific interactions with the microenvironment. Physical microenvironmental conditions such as hypoxia and acidosis 5, adhesion to the extracellular matrix (ECM) 6, growth factors, pro-inflammatory cytokines and chemokines 7, carcinoma- associated fibroblasts and endothelial cells, innate and adaptative immune cells and tumor-associated macrophages contribute to all stages of cancer progression from malignant transformation to metastasis and resistance to therapy. After having a primary focus on the extracellular matrix (ECM) and on angiogenesis in the late 1990's, our knowledge of the mechanisms by which the microenvironment affects tumor progression has grown at an exponential rate. We appreciate better the complexity of the tumor microenvironment and its role in cancer progression and have seen many new concepts emerging (Figure 1). For example, it is well demonstrated that bone marrow-derived cells contribute to tumor vasculogenesis and to the establishment of the pro-metastatic niche. We now fully realize that the immune system can be polarized in a manner that suppresses or promotes cancer progression and that macrophages play an essential role in metastasis. We understand better the mechanism by which the tumor microenvironment promotes therapeutic resistance 8. It is therefore a particularly exciting time in this field, as our knowledge reaches the critical point when it begins to translate into new therapeutic modalities. In this application we are requesting support for a conference on "Tumor Microenvironment Complexity: Emerging Roles in Cancer Therapy" to be held November 3-6, 2011 at the Hilton Orlando Hotel, Orlando, FL. PUBLIC HEALTH RELEVANCE: As we begin to understand how the tumor microenvironment can influence tumor initiation, progression, metastasis, and resistance to therapy, we are better equipped to utilize this knowledge for translation into new therapeutic modalities. The purpose of this timely conference is to bring together experts in the field and more junior scientists to discuss these emerging concepts, to examine their translational importance, and to identify other areas in the field that should be the focus of further investigation.

描述（由申请人提供）：在过去的十年中，越来越认识到肿瘤的非恶性成分，称为肿瘤微环境（TME），在癌症发展和进展中起主要因素作用，在1-4中起着重要作用。这种癌症的异型观点认识到，可能在本质上无法传播或抵抗治疗性损伤的肿瘤细胞可以因与微环境的特定相互作用而获得这些特性。物理微环境条件，例如缺氧和酸中毒5，对细胞外基质（ECM）6的粘附，生长因子，生长因子，炎性细胞因子和趋化因子和趋化因子7，癌相关的成纤维细胞以及内皮细胞，先天性和适应性的细胞和肿瘤对群体的影响，对各种损害的癌症，癌症的伴随癌症的癌症，癌症的效果是癌症的癌症。接受治疗。在主要关注细胞外基质（ECM）和1990年代后期的血管生成之后，我们对微环境影响肿瘤进展的机制的了解以指数式的速度增长。我们更欣赏肿瘤微环境的复杂性及其在癌症进展中的作用，并看到了许多新的概念（图1）。例如，有充分的证明，骨髓衍生的细胞有助于肿瘤血管生成和建立促态生态裂市场。现在，我们完全意识到，免疫系统可以以抑制或促进癌症进展的方式两极化，并且巨噬细胞在转移中起着至关重要的作用。我们更好地理解了肿瘤微环境促进治疗性抗性8的机制。因此，在该领域中，这是一个特别令人兴奋的时期，因为我们的知识达到了开始转化为新的治疗方式的关键点。在此应用中，我们要求支持“肿瘤微环境复杂性：癌症治疗中新兴角色”的会议，将于2011年11月3日至6日在佛罗里达州奥兰多的希尔顿奥兰多酒店举行。 公共卫生相关性：随着我们开始了解肿瘤微环境如何影响肿瘤的启动，进展，转移和对治疗的抵抗，我们可以更好地利用这些知识将这些知识转化为新的治疗方式。这次及时会议的目的是将该领域的专家和更多的初级科学家汇集在一起​​，讨论这些新兴概念，研究其翻译重要性，并确定该领域的其他领域，这些领域应成为进一步调查的重点。
