炎性乳腺癌的临床研究[摘要]目的:炎性乳癌(inflammatorycancer,IBC)是一种罕见且侵袭性高的乳腺癌,通常预后不佳。本研究的目的是评估不同分子亚型炎性乳腺癌患者的临床表现、治疗和预后。方法:一项基于人群的回顾性队列研究比较了不同分子亚型的乳腺癌的特征、3年总生存率(overallsurvival,OS)、乳腺癌特异性死亡率(breastcancer-specificmortality,BCSM)。所有的数据都来源于2010-2013年的监测、流行病学和最终结果数据库(theSurveillance,Epidemiology,andEndResults,SEER)。结果:在2010-2013年的SEER数据库中,符合条件的炎性乳腺癌患者共403名。与激素受体阳性Her-2阴性((HoR)+/HER-)的患者相比,三阴性(triplenegativeTN)乳腺癌患者的肿瘤有更高的组织分级,三阴性肿瘤的分化更差,预后不佳(P<0.05)。随访期间,三阴性乳腺癌的3年OS为62.9%,激素受体阳性Her-2阴性((HoR)+/HER-)的3年OS为79.6%(P<0.05)。此外,三阴性乳腺癌的BCSM率为30.5%,而激素受体阳性Her-2阴性((HoR)+/HER-)患者BCSM率为16.3%(P<0.05)。多变量分析显示,三阴性乳腺癌和Ⅳ期乳腺癌患者有更差的OS和BCSM(eachP<0.05)。多变量分析显示,局部接受过放疗的乳腺癌患者可能提高OS(P<0.05)。研究结果表明,接受乳房切除和保留乳房的患者具有相同的OS(P>0.05)。1结论:结果显示,炎性乳腺癌特别是三阴性乳腺癌患者预后更差。同时,除了乳房全切术外,保乳+放疗可能成为一种可行的治疗方式。[关键词]:炎性乳腺癌;乳腺癌压型;治疗方式;结果[中图分类号]R6ClinicalResearchofinflammatorybreastcancerLIUQian,WUQiao.JingzhouHospital,TongjiMedicalCollege,HuazhongUniversityofScienceandTechnology(HUST)[Abstract]Purpose:Poorprognosisfrequentlyappearsininflammatorycancer(IBC),anrareandaggressivediease.Theaimofthisstudywastoevalutaetheclinicalpresentation,treatmentandoutcomeofpatientswithIBC,withspecialemphasisontheroleoftumorsubtypeinthesepatients.Methods:Aretrospecctive,population-basedcohortstudywasconductedtoinvestigatetumorsubtype-specificdifferenceinvariouscharacteristics,3yearsoverallsurvival(OS)andbreastcancer-specificmortality(BCSM).AlldataareobtainedbytheSurveillance,Epidemiology,andEndResults(SEER)programfrom2010-2013.Results:Inall,403patientswithIBCwereeligibleduringthe2010-2013studyperiod.Comparedwiththehormonereceptor(HoR)+/HER-subgroup,patientswithtriplenegative(TN)breastcancerweremorelikelytohavetumorsthatwerehigheringrade;theywerealsomorelikelytohavetumorswithdifferentiatingpoorlyandwerelesslikelytohavetumorswithdifferentiatingwell(P<0.05).Duringthefollow-upperiod,patientswhowereTNbreastcancerhada3yearsOSof62.9%comparedwith79.6%intheHoR+/HER-subgroup(P<0.05).Furthermore,patientswithTNgrouphadtheBCSMratewas30.5%comparedwith16.3%fortheHoR+/HER-subgroup(P<0.05).MultivariateanalysisrevealedthatapoorerOSandBCSMoccueredinpatientswithTNgrouportumorstagbyIV(eachP<0.05).MultivariateanalysisofOSwithrespecttothelocaltreatmenthistoryshowedthatpatientswhoreceivedradiotherapy(R)weremorelikelytohaveanimprovedOS(P<0.05).Moreover,theresultsdemonstratedthatpatientswhounderwentMastectomyandbreast-conservingsurgeryweremorelikelytohavethesameOS(P>0.05).Conclusions:TheresultsdemonstratethatIBCappearstoaltertheprognosisassociatedwiththeTNsubtype.Meanwhile,BCSplusRmaybecomeafeasibletreatment,besidemastectomy.[Keywords]:Inflammatorybreastcancer;breastsubtype;treatment;outcome炎性乳腺癌是一种少见的侵袭性疾病,相比较与其他类型的乳腺癌,炎性乳腺癌即使经过规范化的治疗后其余后依然很差[1-2]。炎性乳腺癌发发生率不到5%[3-4]。Lee和Tannenbaum在1924年首次使用了炎性乳腺癌的专业术语;Haagensen在1956年将乳腺癌描述为一种临床病理学实...
