In this paper, surgical results of nipple-preserved mastectomy (Glt+Ax) for breast cancer were compared with those of radical mastectomy. In p-stage I breast cancer cases, survival and loco-regional disease-free rate of the nipple-preserved cases were equivalent to those of radical mastectomy group. Although nipple-preserved cases had inferiority to the radical mastectomy cases in the survival rate in p-stage II cases, loco-regional disease-free rate of nipple-preserved cases was equal to that of radical mastectomy cases. On the basis of these results, nipple-preserved mastectomy can be a standard operation of p-stage I, II breast cancer in point of the local control at least.
