Special Issue Information
Dear Colleagues,
Tumor cells coexist and communicate with the rest of the cells present in the tissue where the tumor is generated. Stromal fibroblasts, the various cell types of the blood vessels, and the immune system cells also play an essential role in tumor progression. However, in addition to the cellular components of the tissues, other environmental factors are capable of altering the fragile balance of tumors (oxygen, extracellular matrix deposition, pH, interstitial pressure, etc.). All these previously mentioned factors (cellular and non-cellular) form what is known as the tumor microenvironment.
This tumor microenvironment is always in a fragile balance and is dynamic over time. The capacity of the different cells to adapt to the new environmental conditions generated throughout the progression of the tumor can cause changes that condition the phenotype of the tumor cells. Hypoxia, the appearance of necrotic areas, the infiltration of cells of the immune system, or the deposition of proteins from the extracellular matrix are some alterations that can appear in different regions of the tumor. Additionally, these changes are dependent on the local microenvironment, which causes differences between areas, thus generating tumor heterogeneity.
Non-homogeneous environmental conditions and tumor heterogeneity are critical aspects of tumor progression and in the appearance between tumor cells of resistance mechanisms to the treatments applied in the clinic. This Special Issue will highlight the role of the different players of the tumor microenvironment in cancer progression, covering both basic and more (pre) clinical aspects to improve our understanding of these complex interactions in human tumors.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
