Neutrophils in cancer

Tumor-Associated Neutrophils in Breast Cancer Subtypes

Background: Tumor associated neutrophils (TAN) are related to aggressiveness and a poor prognosis with human cancers. However, the relevance of TAN in breast cancer has not been previously investigated and here we sought to determine their presence among different subtypes. Methods: We analyzed patients with stage I-III breast cancers between 2006 and 2012. Tumors were divided into three subtyp...

iNOS expression and NO production by neutrophils in cancer patients.

INTRODUCTION The tumor-polymorphonuclear neutrophil (PMN) relationship can be altered by the release of toxic molecules, such as nitric oxide (NO). The aim of the present study was to examine the expression of the inducible synthase of NO (iNOS)and NO production by human neutrophils of patients with oral cavity cancer. For comparison we performed similar examinations in autologous peripheral bl...

Function of Neutrophils in Different Phases of Chronic Myelogenous Leukemia

In chronic myelogenous leukemia (CML), the mature granulocytes originate from a stem cell line harboring an abnormal chromosome, therefore it is possible that metabolic-functional abnormalities occur in the morphologically mature cells. In the present study, the phagocytic activity including intracellular killing, nitro blue tetrazolium (NBT) reduction, and phagocytosis were studied in 37 CML p...

Neutrophils and anti-cancer immunity: a paradigm shift in cancer immunotherapy

Neutrophils and TRAIL: insights into BCG immunotherapy for bladder cancer.

Bladder cancer is a huge economic burden on the healthcare system and is responsible for approximately 5% of all cancer deaths in humans. Mycobacterium bovis BCG-based therapy is the treatment of choice for superficial bladder cancer. Bacillus Calmette-Guerin (BCG) instillation in the bladder results in a massive local inflammatory response that has secondary antitumor properties. Recent studie...
