Necrosis

Necrosis can be defined as cell death caused by loss of membrane integrity, intracellular organelle swelling and adenosine triphosphate (ATP) depletion.

Moreover, a rare but possible complication of BMN is the embolism of necrotic bone marrow tissue that then blocks vessels in multiple organs, to provoke infarct.

Introduction

Based on this review, we conclude that BMN is associated with many diseases, and yet presents with no clear pathophysiology. In addition, clinical and laboratory characteristics are non-specific and, in many cases, symptoms are related to the causal condition that is most commonly a hematological disease. Finally, the most important conclusion is that in all cases of BMN a malignant disease must be ruled in or out, given that malignancies are the most common cause of this lesion.

Comments on necrosis What made you want to look up necrosis? Get Word of the Day daily email! Need even more definitions? Rather than considering the notion of cancer as primarily a disorder of cell growth and secondarily of cell death, we would prefer to reverse these and suggest that cancer is associated with disordered cell death, limited apoptosis, and increasingly promotion of necrotic cell death.

When other hormonal factors e. When these necrotic factors are released from dying cells in the relative absence of exogenous pathogen-derived danger signals and cytokines, these factors suppress immunity and enhance wound repair processes, thereby promoting tumor growth and escape from apoptosis. All novel theorems such as these should have practical and testable consequences in the clinic. We would like to suggest that surgical excision, arguably the most effective therapy still for solid tumors, is so effective because it removes both the tumor as well as the necrotic factors and, in their absence, is associated with the inadequate support of the remaining factors to promote the growth of residual local or micrometastatic disease.

For more malignant tumors, local eradication with regional therapies such as radiofrequency ablation or isolated perfusion of treatments may similarly attribute their effectiveness to limiting the release of growth-promoting necrotic factors. For the most advanced tumors which still fail to die an apoptotic death, the only alternative is to block the factors themselves for example with the application of inhibitory antibodies or by blocking their receptors.

Necrosis - an overview | ScienceDirect Topics

These strategies are in early development now and are being formally tested preclinically in anticipation of their application in patients with cancer and other acute and chronic inflammatory conditions. Resolution of the role of necrotic cell death will need to rely on its verification in carefully conducted clinical trials in which these notions are directly tested.

Many of the notions described here have been the result of fruitful discussions with several colleagues. Without naming them all, we have been enriched by a continued enthusiasm and support for these novel ideas by Drs. Research support from the University of Pittsburgh Cancer Institute and its Department of Surgery allowed for this renaissance of research and critical analysis of cancer during our recent career changes.
