Bac.ground Loc.l rec.rrenc. remains a serious problem among pat.ent. undergoing breast c.nservat.ve surgery. t.is study aimed at.ident.fying risk fac.0}rs for residual disease aft.r breast c.nservat.ve surgery. Met.ods t.is ret.ospec.0}ve study was based on pat.ent. wit. invasive breast c.nc.r who have rec.ived breast c.nservat.ve surgery and subsequent.c.mplet.on mastec.0}my. All pat.ent. had a c.ear resec.0}on margin in t.e init.al operat.on. We analyzed t.e assoc.at.on bet.een t.e presenc. of residual disease during c.mplet.on mastec.0}my and t.e following risk fac.0}rs： t.staging, young age, and presenc. of ext.nsive int.aduc.0}l c.mponent.（EIc., a c.ose margin, lymphovasc.lar permeat.on （LVP）, posit.vit. of estrogen rec.pt.r, progesterone rec.pt.r, and c.erbB-2. Result. Residual disease was enc.unt.red in 21 （45.7%） of 46 pat.ent.; EIc.was present.in 28 pat.ent. （60.9%）, of whom 17 had residual disease. Presenc. of EIc.during breast c.nservat.on surgery was assoc.at.d wit. a higher risk of residual disease during c.mplet.on mastec.0}my （P=0.011）. Ot.er variables were not.stat.stic.lly signific.nt.risk fac.0}rs for presenc. of residual disease. No loc.l rec.rrenc. was rec.rded in our c.hort. and t.e disease-free survival and overall survival aft.r c.mplet.on mastec.0}my were similar for pat.ent. who had residual disease and t.ose who had not. c.nc.usions t.e presenc. of EIc.is a signific.nt.risk fac.0}r for residual disease in pat.ent. aft.r breast c.nservat.ve surgery. Our findings may suggest t.e indic.t.d value of c.mplet.on mastec.0}my in pat.ent. wit. EIc.during init.al breast c.nservat.ve surgery t. dec.ease t.e risk of subsequent.loc.l failure.
