Report on the annual meeting

CONSERVATIVE RADICAL (WITH PRESERVE OF THE MINOR PECTORAL MUSCLE), RADICAL AND EXTENDED RADICAL MASTECTOMIES FOR BREAST CANCER

5-year survival rate of 347 cases of operable breast cancer was 74.9%, which consisted of 92% stage I, 77.8% stage II and 48.4% stage III. Effectiveness of the three methods was almost same for each stage. In stage I, all methods resulted in a good prognosis, even if axillary metastasis was present. The statistic analysis of the case of non palpable axillary lymph node indicated that those which had less than three metastatic nodes were found in 29% of the whole cases, those with 4-6 metastatic nodes in 8.1% and those with more than 7 metastatic nodes in 4.8%.
To diminish the risk of such no palpable metastasis, the size of mass is a determinant factor.
The case with non palpable axillary lymph node and with mass of less than one cm. may be the most appropriate indication for minor surgery such as Madden's or Auchincloss'conservative mastectomy.
In TINOMO case (stage I), Patey's conservative radical mastectomy is recommended.
5-year servival rate of case with parasternal metastasis was low, 40.9%. The frequency of meatastasis related to the location of mass, and generally accelerated by the degree of axillary metasstasis. In 109 cases a mass located at inner-half lesion, radical mastectomy plus irradiation and extended radical mastectomy showed almost same prognosis in 5-year survival rate.
