Intensity-modulated radiotherapy (IMRT) is nowadays the most sophisticated form of radiation therapy to carry out three-dimensional conformal radiotherapy (3D-CRT), employing non-uniform intensities dose beams to cover the target volume. The usefulness is based on three classical radiation therapy hypotheses: higher doses increase the local control of the tumor; a higher local control of the primary tumor improves survival; and three-dimensional conformal radiotherapy allows the delivery of higher radiation doses covering the tumor while minimizing the incidence of secondary effects. A critical review of the publications related with the state of the art of the clinical experience in IMRT, specially those referred to head and neck tumors is made, indicating possible new strategies in the near future.
