Prognostic Significance of Tumor-Associated Macrophages in Solid Tumor: A Meta-Analysis of the Literature

Abstract: PurposeTumor associated macrophages (TAMs) are considered with the capacity to have both negative and positive effects on tumor growth. The prognostic value of TAM for survival in patients with solid tumor remains controversial.Experimental DesignWe conducted a meta-analysis of 55 studies (n = 8,692 patients) that evaluated the correlation between TAM (detected by immunohistochemistry) and clinical staging, overall survival (OS) and disease free survival (DFS). The impact of M1 and M2 type TAM (n = 5) on survi… Show more

“…This hypothesis is reinforced by the increasing density of immune cells in the bladder tissues during the course of BBN treatment. Moreover, the massive presence of tumor-associated macrophages in late clinical staging of patients with bladder cancer [47] and the association between tumor infiltrating lymphocytes and the recurrence of non-muscle-invasive bladder cancer [48] further suggest the chronic inflammatory process and cancer progression association.…”

“…Traditionally, macrophages can be categorized as either classically activated (M1) macrophages or alternatively activated (M2) macrophages (Biswas and Mantovani, 2010; Lawrence and Natoli, 2011; Mosser and Edwards, 2008). M1 macrophages play key roles in the pro‐inflammatory and antitumor responses and are induced by toll‐like receptors (TLRs), IFN‐γ, and lipopolysaccharide (LPS), while M2 macrophages are activated by IL‐4 and IL‐13 and are responsible for angiogenesis, tissue remodeling, and tumor progression (Mantovani et al ., 2007; Zhang et al ., 2012). …”

“…La tumeur primaire sécrète des facteurs pro-inflammatoires (protéine S100-A8/9, TNF [tumor necrosis factor a]) qui participent au développement de ces niches métastatiques dans l'organe cible. Ces données expérimen-tales, obtenues in vitro ou dans des modèles murins, sont renforcées par l'observation, chez l'homme, d'une corrélation entre la présence de macrophages ou de G-MDSC dans la tumeur primitive et le dévelop-pement de métastases chez l'homme [27]. L'inflammation de l'organe cible, par exemple du poumon, de la gencive ou des os, peut entraîner l'apparition accélérée de métastases [28].…”
