Cell death is an important physiological regulator during development, tissue homeostasis and stress response but it is also a protective tumor suppressive mechanism. Tumor cells almost universally acquire the ability to evade cell death pathways that in normal cells act as a protective mechanism to remove damaged cells. As a result, a population of death-resistant cells with accumulating genetic and epigenetic abnormalities contributes to malignant transformation.

Any alteration of the homeostatic balance between survival and death is therefore a critical factor in carcinogenesis. Several forms of cell death exist and cross talk among them is emerging; however, we still miss many molecular details. It becomes essential to revisit the role of each type of cell death to understand interconnections existing between different cell death pathways as well as the network of their mediators to eventually develop new effective …
