This period was before the release of Australian treatment recommendations. METHODS: All new cases of ductal carcinoma in situ diagnosed between 1 April and 30 September in 1995 and 1999 were identified from the population cancer registry. Treating surgeons completed a questionnaire on the presentation and management of each case. In 1995, 64 out of 70 surgeons returned questionnaires for 137 cases (case response, 94%). In 1999, 68 surgeons treated 159 registered cases and 141 completed surveys were returned (case response, 89%). RESULTS: More cases underwent an image-guided biopsy in 1999 (54%) than in 1995 (34%). Breast-conserving surgery (BCS) was used to treat 69% of cases in 1999 and 63% in 1995. The use of axillary procedures (clearance or sampling) for women treated by mastectomy decreased from 61% in 1995 to 30% in 1999. More patients treated with BCS had margins simply described as "clear" in 1995 (49%) than in 1999 (21%). In 1995, only 7% of cases treated with BCS had radiotherapy, and this was 25% in 1999. CONCLUSION: In both 1999 and 1995, the majority of patients were treated by BCS, but only a minority received radiotherapy.
