Tumor growth with nutrients: stability of the tumor patches [PDF]
arXiv, 2022 In this paper, we study a tumor growth model with nutrients. The contact inhibition for the tumor cells, presented in the model, results in the evolution of a congested tumor patch. We study the regularity of the tumor patch as the nutrients' diffusion strength $D$ diminishes.

Mathematical modeling of tumor therapy with oncolytic viruses: Effects of parametric heterogeneity on cell dynamics [PDF]
, 2006 One of the mechanisms that ensure cancer robustness is tumor heterogeneity, and its effects on tumor cells dynamics have to be taken into account when studying cancer progression.

Circulating tumor cells isolation: The “post-EpCAM era” [PDF]
, 2015 Circulating tumor cells (CTCs) represent a submicroscopic fraction detached from a primary tumor and in transit to a secondary site. The prognostic significance of CTCs in metastatic cancer patients was demonstrated for the first time more than ten years

Tumor neoantigens and tumor immunotherapies
AGING MEDICINEAbstractAs a high‐risk group of patients with cancer, the elderly exhibit limited efficacy with traditional treatments. Immunotherapy emerges as a promising adjunctive therapeutic approach that holds potential in addressing the needs of geriatric patients with cancer.

Tumors benignes vs. tumors malignes [PDF]
Llengua, Societat i Comunicaci�, 2012 Tumor is the word used to refer to an abnormal, excessive growth of a mass of certain cells, which can be similar to normal tissue cells or which can be atypical to other bodily cells. The essential difference between benign and malignant tumors lies in the latter’s ability to spread throughout the body, making their prognoses worse than those of ...

Medicina, 2019 Background and Objectives: The tumor microenvironment has been widely implicated in tumorigenesis because it harbors tumor cells that interact with surrounding cells through the circulatory and lymphatic systems to influence the development and progression of cancer.

Statistical mechanics model of angiogenic tumor growth [PDF]
Phys.Rev. E 85, 010901(R) (2012), 2011 We examine a lattice model of tumor growth where survival of tumor cells depends on the supplied nutrients. When such a supply is random, the extinction of tumors belongs to the directed percolation universality class. However, when the supply is correlated with distribution of tumor cells, which as we suggest might mimick the angiogenic growth, the ...

Recombinant Listeria promotes tumor rejection by CD8+ T cell-dependent remodeling of the tumor microenvironment. [PDF]
, 2018 Agents that remodel the tumor microenvironment (TME), prime functional tumor-specific T cells, and block inhibitory signaling pathways are essential components of effective immunotherapy.

Impact of decitabine on immunohistochemistry expression of the putative tumor suppressor genes FHIT, WWOX, FUS1 and PTEN in clinical tumor samples. [PDF]
, 2014 BackgroundSince tumor suppressor gene function may be lost through hypermethylation, we assessed whether the demethylating agent decitabine could increase tumor suppressor gene expression clinically.
