title: [En-bloc treatment of tumors of the hypopharyngeal-laryngeal-tracheal tract with a new isocentric multipendular technic].
abstract: The authors propose a new technique for the treatment of hypopharyngeal-laryngeal-tracheal tract tumors using cobalt-60 irradiation. This technique allows the simultaneous irradiation of both primary tumor and cervical lymph nodes. Therapeutically effective doses can be administered without affecting the spinal cord. The above-mentioned technique consists of 3 isocentric rotations, the widest one carried out by interposing a small lead bar shielding in the middle of the field. Dose distributions obtained in an Alderson-Rando phantom and in a patient are reported.
