[Sequelli and complications of irradiation of mammary carcinomas]

a) Doses of 6 000 to 6 500 rads to the supra- and sub-clavicular regions are an extreme limit which should not be exceeded (the three cases of serious complications previously cited has received doses of 6 000 to 7 500 rads). b) With the technique before 1969, we were not giving doses of 6 000 to 6 500 rads to the supra- and sub-clavicular regions as we had thought, but in reality a lesser dose of 5 000 to 5 500 rads. In addition this dose is revealed in the analysis to be sufficient for controlling the majority of lymph nodes microscopically invaded at the same time permitting as to avoid serious complications. c) All the sequelli serious complications follow principally irradiation of the axillary and supra-clavicular regions.
