Breast Conservation in the Treatment of Breast Cancer: Community-Based Experience

Background. Results of large, randomized studies in the 1980s established wide excision and radiation as an accepted breast cancer treatment approach. We evaluated our initial results with this treatment in the community setting. Methods. We evaluated the frequency and outcome of breast conservation treatment in in 303 women with invasive ductal carcinoma from 1985 to 1995. Results. The frequency of breast conservation treatment increased from 9% during 1985 to 1989 to 24% during 1990 to 1995. With a median follow-up of 4.7 years, there were 19 (6%) ipsilateral recurrences. Metastatic disease occurred in 23 patients (8%). Overall 5-year survival was 95%, and 5-year recurrence-free survival was 90%. Twelve patients died of breast cancer. Conclusions. Increased use of breast conservation in our community practice parallels the national trend, with similar treatment results. Our findings suggest the successful integration of research-proven innovations into community practice.
