Conformal radiotherapy in head and neck tumors: increased tumor control and decreased morbidity?

Conformal radiotherapy in head and neck tumors is only at its premise. Its offers attractive prospect to decrease late morbidity and increase loco-regional control probability not only in patients with primary treatment but also in patients with recurrent disease previously fully irradiated. Such modality however, requires complex infrastructure and qualified staff. Comprehensive evaluation are thus needed to determine the patient population that will benefit the most from this new promising technique before its use can be generalized.
