Background
South East Sweden with 976 000 inhabitants is served by nine hospitals with specialized breast surgeons. Population‐based mammographic screening was introduced in 1986 for women aged 40–74 years. Patients with primary breast cancer were treated according to a joint management programme.
Method
All patients were reported to a regional cancer registry from which breast cancer incidence, treatment and survival in this defined population were reported.
Results
A total of 7892 women had their first invasive breast cancer diagnosed between 1986 and 1999. The median tumour size was 17 mm and 29·9 per cent had axillary metastases. Some 49·8 per cent of these women had a modified radical mastectomy and 31·9 per cent had a segmental resection with axillary clearance. Postoperative radiotherapy was given to 40·3 per cent of the women after mastectomy and to 87·1 per cent after breast‐conserving surgery. Tamoxifen and chemotherapy were used as adjuvant treatment except in low‐risk patients. Breast cancer‐specific survival rate for all stages was 83·5 per cent at 5 years and 74·0 per cent at 10 years. Respective values were 95·8 and 90·9 per cent for patients with stage T1 N0 M0 tumours, and 77·7 and 62·4 per cent for those with T1–2 N1 M0 tumours.
Conclusion
Breast specialists treating women with breast cancer according to a joint management programme have achieved very good survival rates. Copyright © 2004 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
