Topical Collection Information
Dear Colleagues,
The interplay between tumor cells and their microenvironment (tumor microenvironment, TME) is a well-established hallmark feature of human tumors. TME comprises different cells, such as fibroblasts, immune cells, adipocytes, endothelial cells, as well as bone cells in distant sites of dissemination.
Cancer cells secrete biological factors to educate their neighboring cells toward an aggressive, pro-inflammatory, and pro-tumoral phenotype. In turn, cells of the TME release signals directed toward cancer cells to favor tumor growth, progression, dissemination, and treatment resistance. Interestingly, a cancer metabolic reprogramming is often involved in this pro-tumoral activity of TME cells.
This multifaceted crosstalk is mediated by different biological factors, such as cytokines, chemokines, growth factors, extracellular matrix remodeling enzymes, as well as by extracellular vesicles (EVs). Specifically, EVs serve as transporters of different bioactive cargos, including proteins, nucleic acids, miRNAs, and lipids, from parental to both neighboring and distant target cells to participate in the various steps of malignant tumor development and progression by triggering or suppressing different signaling pathways in recipient cells.
The vicious crosstalk between cancer cells and their neighboring cells in the TME is now considered not only a prognostic/predictive biomarker of tumor growth and progression, but, more importantly, an effective target for novel and valuable therapeutic strategies.
The aim of this Collection is to invite authors to contribute original research as well as review articles highlighting the current concepts of the molecular mechanisms involved in the communication between tumor cells and their microenvironment, paving the way toward more specific and personalized medicine for cancer patients.

Abstract: Abstract: Lung cancer is the most deadly cancer in the world. Approximately 30% of diagnosed patients have an advanced lung cancer disease. Understanding the mechanisms that regulated the metastasis formation from primary lung cancer is an important unmet clinical need. One of the first steps during the establishment of lung cancer metastases includes the formation of the pre-metastatic niche in the distant organs that may occur at the first phase of the cancer development. The pre-metastatic niche is established by the cross-talk among primary tumor secreted factors and stromal components at the distant site. Mechanisms of primary tumors escape and seeding of distant organs rely on specific properties of tumor cells and they are also tightly regulated by the interactions with stromal cells at the metastatic niche that finally dictate the success of metastasis establishment.
Here, we summarize mechanisms underlying the pre-metastatic niche formation starting from how lung primary tumor cells modulate the distant site of metastasis through the release of several factors focusing on Extracellular Vesicles. Then, we describe the complexity of Circulating Tumor Cells (CTCs) that represent the seed of metastasis and how stromal cells can help their metastatic dissemination. Finally, we evaluate the contribution of stromal and immune cells at the distant site in the control and/or support of metastatic niche formation. Overall, we present an overview of the step of metastatic cascade of lung cancer focusing on the interactions, physical or mediated by soluble factors, between tumor cells and stroma cells subtending metastasis development.
