Breast preservation versus mastectomy--recurrence and survival rates of primary breast cancer patients treated at the UFK Bonn.
The aim of this retrospective long-term analysis was to evaluate the approach of breast conservation in the light of the results obtained, on the basis of mastectomy, in patients with early breast carcinoma. Additionally, the effect of internal mammary and supraclavicular radiotherapy was analyzed. Therefore, local-regional recurrence (LRR) and survival rates were examined in 411 patients with T1 and T2 stages who had undergone either breast-preserving surgery with radiation or mastectomy. Individual risk factors such as nodal status, lymphangiosis carcinomatosa and age of the patients were evaluated, too. The rate of local-regional recurrence in patients who were treated by mastectomy and conservative surgery was 9.2% and 11.0%, respectively, with relapse happening earlier in the latter group (median of 16 vs. 24 months). Survival rates, however, were not different in the two groups. Tumour stage and nodal status had no influence on the local-regional recurrence rate in either group. In connection with lymphangiosis carcinomatosa, however, the rate increased to 14.5% (mastectomy) and 19.0% (breast-preserving surgery), respectively. Patients < or = 40 years had an even higher risk of LRR, with 20.6% when they underwent mastectomy and 30.8% following breast conservation. Internal mammary and supraclavicular radiotherapy had no positive effect on the survival rates, neither in the mastectomy nor in the breast conservation group. As a conclusion, in more than 60% of all T1 stages. and more than 50% of all T2 stages, the therapeutic concept of breast preservation seems to be justified.
