Results of the conservative surgical and irradiation treatment of 132 nonpalpable ductal carcinomas in situ of the breast

摘要

PURPOSE: Retrospective analysis of results of treatment of 132 subclinical ductal carcinomas in situ, non-palpable. MATERIAL AND METHODS: Patients were treated with limited surgery and 70 Gy radiation therapy (70 Gy). RESULTS: With a median follow-up of 7 years, the total recurrence rate was 6%, and the actuarial rate at 5 years 4% and at 10 years 13% at. These have no influence on recurrence on the specific actuarial survival rate which was 100% at 10 years. In spite of five infiltrating recurrences of seven, no metastasis appeared 48 months after the salvage surgery. The global rate of breast preservation was 92% at 7 years. DISCUSSION AND CONCLUSION: Therapeutic indications were developed taking into account the present analysis and a literature review (2,338 in situ ductal carcinomas, palpable or not, treated with conservative surgery, with or without adjuvant radio-therapy).
