·574·恶性副神经节瘤的诊治探讨王先进1沈周俊1钟山1朱照伟1周文龙1昊瑜璇1祝宇1孙福康1邵远1张存明1[摘要]目的:提高恶性副神经节瘤(MPGL)的诊治水平。方法:回顾性分析2003年4月一2011年1月诊治的12例MPGI。患者的临床资料。高血压10例(83.3%),腰腹部疼痛3例(25.o%)。血浆游离变肾上腺素类物质(MNs)和24h尿儿茶酚胺(cA)升高者分别为100.O%(12/12)和83.3%(10/12)。B超、CT、MRI和⋯H可碘苄胍扫描(131}MIBG)定位准确率分别为83.3%(10/12)、91.7%(11/12)、80.o%(4/5)和88.9%(8/9)。1例行放射治疗,11例行开放手术治疗。结果:原发性肿瘤9例,复发性肿瘤3例;单发性肿瘤8例,多发性肿瘤4例。根据肿瘤的中心定位:腹主动脉旁6例,下腔静脉后2例,膀胱2例,肾门2例。根据术中所见确诊恶性5例(41.7%)。病理检查11例,确诊恶性8例(72.7%)。肺转移l例,肝转移1例,骨转移1例,局部淋巴结转移3例,广泛淋巴结转移2例,2个或多个脏器同时发生转移2例。9例随访4~84个月,平均39个月;复发4例,再次手术;因多发浸润及远处转移死亡2例。结论:病理难以区分副神经节瘤的良恶性,需结合影像学检查、生化检查及术中所见。根治性肿瘤切除是治疗MPGI.最有效的方法,肿瘤复发时再次手术仍然有效;无法手术者可用放化疔控制高血压及延缓疾病进展。长期随访观察肿瘤的转移情况是确诊疑似病例的重要方法。[关键词]副神经节瘤;恶性;诊断;治疗doi:10.3969/j.issn.100卜1420.2011.08.005[中图分类号]R736.6[文献标志码]A[文章编号]1001一1420(2011)08一0574一05TheDiagnosisandTreatmentOfMalignantParagangIiomaXianjinWANGlZhoujunSHENlShanZHoNGlZhaoweiZHUlWenlongZHoUlYuxuanWUlYuZHUlFukangSUNlYuanSHA01CunmingZHANGl(1DP户口,.£7孢P”£o,L陪ozogy,R“i歹i咒Hospi£口Z,S矗盘以g^口i-,inoTb行g【,陀i"ersifySf^oDZo,Medi—ci咒P,S^口,29^口i,200025,C’^i咒口)..Abst憎ctobjective:Toimprovethediagnosisandtreatmentofmalignantparaganglioma(MPGL).Methods:Theclinicaldataof12casesofMPGLfromApril2003toJanuary2011wereretrospectivelyanalyzed.Hyperten—sionwasobservedin10cases(83.3%)andabdominalpainwasin3cases(25.O%).Thepositiverateofplasma-freeMNsand24一houfurineCAindiagnosingMPGLwas100.0%(12/12)and83.3%(10/12)respectively.Themainlocalizatic:ndiagnosesincludedB—Ultrasound,CT,MRIandl31I_MIBG,withthepositiveratesof83.3%(10/12),.91.7%(11/12),80.O%(4/5)and88.9%(8/9)respectively.onecaseunderwentradiotherapy,andtherestof11casesunderwentopensurgicaltreatment.ResuIts:Ninecaseswereprimarytumorsand3recurrenttumors;Eightcasesweresingletumorand4multipleones.Themainanatomiclocationsoftumorswereasfollows:6wereadja—centtotheabdominalaorta,2adjacenttotheinferiorvenacava,2inthebladder,2adjacenttotherenalhilum.Fivecases(41.7%)werediagnosedMPGLint}aoperativelyaccordingtotumorfeatures.Elevencasesunderwentpatho—logicalexaminationand8(72.7%)werediagnosedMPGL.Themetastaticsitesoftumorincluded1casesof1ung,1casesof“ver,1casesofbone,3casesofregionallymphnode,2casesofextensivelymphnodeand2casesofmulti—pleorganssimultaneously.Ninepatientswerefollowedupfor4to84months(mean,39months),duringwhich4caseshadtumorrecurrenceandunderwentre_operation.Twocasesdiedfromtumorprogressionandmetastasisandtheremaininghavebeensurvivaltodate.C:onclusions:AsthebiologicalbehaviourofMPGLcannotbepredictedwithcertaintyfrompathology,thediagnosisofmalignancyisratherdifficult.Itisnecessarytocombinepathologicalexaminationwithimagingexaminations,laboratoryinspectionandintraoperativefindingsespecially.Tomedicallyinoperablepatients,radiotherapyandchemotherapymaybeusefu...
