Abstract
Head and neck tumours have poor prognosis: with surgery and radiotherapy, local control is achieved but is associated with damage to speech and swallowing function. Conventional 2-D radiotherapy is based on one fraction of 1.8-2.0 Gy per day; increasing the number of fractions, a higher dose can be administered, with an increase in local control. Today, conventional treatment can be replaced by new techniques: with 3-D Conformal Radiotherapy, higher doses of radiation can be delivered to cancer cells while reducing the amount of radiation received by surrounding healthy tissues: Intensity Modulated Radiation Therapy permits an irregular dose distribution that conforms exactly to the volume of the target, increasing local tumour control and survival and decreasing radiation-induced side-effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
