Killing a cancer: what are the alternatives?

Evading programmed cell death is one of the hallmarks of cancer. Conversely, inducing cell death by pharmacological means is the basis of almost every non-invasive cancer therapy. Research over the past decade has greatly increased our understanding of non-apoptotic programmed cell death events, such as lysosomal-mediated cell death, necroptosis and cell death with autophagy. It is becoming clear that an intricate effector network connects many of these classical and non-classical death pathways. In this Review, we discuss converging and diverging features of these pathways, as well as attempts to exploit this newly gained knowledge pharmacologically to provide therapeutics for cancer.
