[Technics for irradiation of the neck in the treatment of lymph node metastases from solid tumors of the head and neck region].

Some common irradiation techniques for nodal metastasis of head and neck solid tumors are described and analyzed, that can be performed by means of a cobalt unit or by high energy electron beams. Limits and indications of each technique are evaluated particularly referring to dose distribution in the target volume and to isoeffect levels (TDF, CRE) that can be expected in normal tissues, at the end of treatment for different regimes.
