A method of radiation treatment for advanced neck node metastases

Thirty-one advanced cervical node metastases (staged N3 according the U.I.C.C. system; 4 N2A, 27N3A according the A.J.C. system) were treated using a particular schedule consisting in two courses: in the first, only the palpable tumor was irradiated with several low energy beams (3.3 mm Al HVL), using as X ray tube operated at 60 kV; in the second course, the whole lymphatic area was treated with 60 Co and conventional fractionation. Palpable disease received 7500 to 10,500 cGy in a overall time of 45-55 days. The local control rate was 87%, without any severe complication. The four (13%) failures were all related to the lowest dose levels.
