The progress of breast conserving surgery combined with intraoperative radiotherapy for early stage breast cancer / 中华内分泌外科杂志

ABSTRACT

Currently,the incidence of breast cancer ranks first at home and abroad of female cancer and the age of onset tends to be younger.Due to the local changes of the tumor residual cavity after the breast conserving surgery,we can't accurately delineate the irradiation range using traditional breast conserving surgery combined with external irradiation of whole breast and tumor bed plus the amount,and the course of treatment is longer.Intra-operative radiation therapy (IORT) can avoid the impact of respiratory motion and postural changes.Meanwhile,it can immediately irradiate the tumor bed intraoperative accurately.For patients,IORT can shorten the cycle of radiotherapy and reduce irradiation on the skin and subcutaneous tissue.So IORT is convenient,easy to be accepted,and it has relatively few complications,good cosmetic results and so on.In recent years,more and more Cancer Center choose breast conserving surgery combined with IORT for the treatment of early stage breast cancer and do researches to the indications,methods,dosage,efficacy and prognosis of IORT.
