Purpose: To analyze the long-term results of a pilot study assessing excision and brachytherapy as salvage treatment for local recurrence after conservative treatment of breast cancer. Methods and Materials: Between December 1990 and March 2001, 36 patients with breast-only recurrence less than 3 cm in diameter after conservative treatment for Stage I or II breast carcinoma were treated with local excision followed by high-dose rate brachytherapy implants (30 Gy in 12 fractions over a period of 5 days). No patient was lost to follow-up. Special attention was paid to local, regional, or distant recurrences; survival; cosmesis; and early and late side effects. Results: All patients completed treatment. During follow-up (range, 1-13 years), 8 patients presented metastases (2 regional and 6 distant) as their first site of failure, 1 had a differed local recurrence, and 1 died of the disease. Actuarial results at 10 years were as follows: local control, 89.4%; disease-free survival, 64.4%; and survival, 96.7%. Cosmetic results were satisfactory in 90.4%. No patient had Grade 3 or 4 early or late complications. Of the 11 patients followed up for at least 10 years, all but 1 still had their breast in place at the 10-year stage. Conclusions: High-dose rate brachytherapy is a safe, effective treatment for small-size, low-risk local recurrence after local excision in conservatively treated patients. The dose of 30 Gy of high-dose rate brachytherapy (12 fractions over a period of 5 days twice daily) was well tolerated. The excellent results support the use of breast preservation as salvage treatment in selected patients with local recurrence after conservative treatment for breast cancer.
