N2 - PURPOSE: The following article is a review of 23 years of breast-conserving therapy in our hospital. This study was performed to assess and improve the follow-up care of women with early breast cancer and to evaluate whether or not biannual mammogram is useful. METHODS AND MATERIALS: Between 1972 and December 1995, 3072 women with pathological size pT1 and pT2 breast cancer were treated with conservative surgery and radiation therapy. Eighty-five patients developed a recurrence in the treated breast as the first site of failure, 12 of which had positive axillary nodes. In the following patient study, those with an noninvasive recurrence were excluded. A retrospective assessment of the entire mammographic course was made, starting with the mammogram at the time of original diagnosis to the mammogram of the recurrence. RESULTS: In our study group the probability for local failure ranged from 1 to 2% per year. At 5 and 10 years the actuarial rates were 5 and 10%. The median time to recurrence was 41 months (range 8-161). Twenty-six (31%) recurrences were detected by mammography alone, 10 (12%) by clinical examination only, and 35 (41%) by both methods. For the patients with an ipsilateral recurrence, the overall actuarial 5- and 10-year survival after treatment was 87 and 70%, respectively. The 5-year actuarial rate of survival from salvage mastectomy was 61%. CONCLUSION: Considering the high percentage of recurrences detectable by mammography and the possibility of detection within a short-term interval, we think biannual mammographic follow-up is appropriate for the first years following breast-conserving therapy.
