ABSTRACT

Objective To investigate the efficacy,side effects and cosmetic effects of breast-conserving operation combined with radiotherapy for patients with breast cancer. Methods Forty-three patients with early stage of breast cancer(n=30 for stage I and n=13 for stage II) were performed extended resection plus axillary lymph node dissection or quadrant resection plus axillary lymph node dissection.After operation,tangential field irradiation was conducted with 50 Gy of X ray,tumor bed was irradiated with additional 10 Gy of electron beam,and supraclavicular field irradiation was also administered with 30 Gy of X ray and 22 Gy of electron beam. Results There was no recurrence during the follow up for 14 to 50 months.The acute side effects of radiotherapy included breast complaints(n=10,grade Ⅰ,23.26%),skin erythema and hyperpigmentation(n=19,grade Ⅰ,44.19%),moist desquamation(n=5,grade Ⅱ,11.63%) and radiation esophagitis(n=4,grade Ⅰ,9.30%),while one patient experienced radiation esophagitis one month after radiotherapy.No such complications as skin fibrosis and necrosis,angiotelectasis,breast and upper extremity edema occurred.The short-term cosmetic effects were satisfactory to 93.02% of all the patients. Conclusion For early stage of breast cancer(stage I and stage Ⅱ),breast-conserving operation combined with radiotherapy may yield satisfactory survival rate and short-term cosmetic effects,as well as low incidences of side effects.
