The search for effective cancer therapies is one of the foremost priorities of modern-day research. In recent times, enormous strides have been made in the understanding of the molecular events that underlie cancer progression and in the development of promising therapies against relevant molecular targets. The molecular signalling pathways that modulate tumourigenesis, especially those involved in cell migration and adhesion are logical foci for molecular intervention. Angiogenesis is a validated target from which combination approaches are now being entertained, and agents against new and known targets are under development. Further advances are needed to use these agents to their best advantage and to demonstrate proof of concept of the target. To that end, new technologies are being developed and applied to patient trials. The local microenvironment and the tumour-host interface are dynamic areas that are understudied as therapeutic directions. Stromal therapy, focused to the paracrine interactions at the microenvironmental level is an important new direction.
