High precision radiotherapy (RT) is exiting and has shown promise in dose escalation to target while reducing dose to adjacent critical structures and thus reducing complications while maintaining or improving survival functions. High precision RT techniques used in brain tumours are usually three dimensional conformal RT (3D-CRT), intensity modulated RT (IMRT), stereotactic conformal radiotherapy (SCRT) and radiosurgery (SRS). These high precision techniques needs expertise, time, resources and are expensive. Recent results from prospective studies have suggested favorable clinical outcome in the form of improved local control, survival and importantly minimizing later morbidity, after conformal techniques and justify their use in clinical practice.
