Since 1960 more than 3000 consecutive patients with operable infiltrating breast carcinoma were treated by radiation therapy or without primary limited surgery, which usually consisted of local excision. For tumors smaller equal to 5 cm the ten-year crude survival rate is 77% for palpable axillary nodes (T1-2N0) and 63% having adenopathy (T1-2N0). exceeding diameter (T3N0-1) 34%. Thirty-five percent alive free disease at ten years required a secondary operation presumed regional tumor...

The frequency, time course, and prognosis of local recurrence following primary radiation therapy in 152 patients with early breast cancer treated before 1967 were examined. Local occurred at a constant rate over the first 14 years after treatment. crude 15-year was 22%. Of 30 who developed an isolated underwent definitive secondary surgery, 10-year freedom from distant relapse 50%. These results indicate that by require long-term follow-up to detect curable recurrences.
