| In conventional conflict, enemy formations and functions are targeted and the battlefield is cleanly divided into deep, close and rear operations; in peace support operations, "adversary" target sets are the populace's societal institutions and the "battlefield" is a nonlinear maneuver space defined in terms of time and events rather than geographic locations. The dogma for treatment of cancer has changed, with the cytotoxic drugs used in chemotherapy regimes set to lose their dominance and be used alongside targeted therapies that are being developed with the aim of more specifically targeting cancer cells. While fragmentation of the oncology market is set to occur as treatment becomes based on tumor growth drivers rather than primary tumor site, the use of targeted therapies, such as anti-angiogenesis, will occur in combination with traditional cytotoxic chemotherapy agents. |
