Breast conserving surgery (BCS) is now a standard surgical treatment for early breast cancer. The number of patients with tumors under 3 cm who underwent breast conserving surgery overtook the number of patients who underwent total mastectomy for the first time in Japan in 2003. We have been employing breast conserving surgery with primary reconstruction using a lateral tissue flap (LTF), and have performed breast conserving surgery for 266 patients from 1990 to 2002. The incidence of local relapse was 5.6%. Although we did not irradiate a low risk group of 101 patients, our method is not inferior to other reports in which all cases underwent irradiation. Primary reconstruction with LTF has three advantages. The first is that we can avoid poly-surgery for breast reconstruction. The second is that the volume of the graft is maintained longer than reconstruction with a musculo-cutaneous flap. The third is that patients can avoid allergic reactions or granulomas as seen with artificial prosthesies. In conclusion, breast conserving surgery with immediate volume replacement with a LTF is a reasonable surgical procedure and has the advantage of avoiding unnecessary surgical procedures for reconstruction and surgical invasion without delaying the diagnosis of local relapse. Moreover, an adequate assessment of risk can spare low risk groups irradiation.
