Primary breast cancer. Complications of axillary management.

The complications following surgery and postoperative radiation therapy in the management of the axilla in 187 patients with primary breast cancer treated between 1978 and 1982 have been studied. Although no difference in complication rate could be detected between the three different postoperative radiation schedules utilised there was a strong and positive correlation between complication rate and increasing extent of surgical intervention. When the groups were sub-divided according to the extent of surgery performed, no differences in regional recurrence rates were observed but complication rates (defined as significant lymphoedema of the arm and/or restriction of shoulder movements) were significantly different (p less than 0.001) at 30 months between those who had no surgical intervention (25%), those who had had 'sampling' performed (50%) and those who had had formal dissection performed (84%).
