中國(guó)人群肝癌篩查指南一、本文概述Overviewofthisarticle肝癌作為全球范圍內(nèi)的高發(fā)性、高致死性惡性腫瘤，其早期篩查和診斷對(duì)于提高患者的生存率和生活質(zhì)量至關(guān)重要。近年來(lái)，隨著醫(yī)學(xué)技術(shù)的不斷進(jìn)步和肝癌流行病學(xué)特征的深入理解，我國(guó)肝癌篩查工作已取得顯著進(jìn)展。然而，由于缺乏統(tǒng)一的篩查標(biāo)準(zhǔn)和指南，各地在實(shí)際操作中仍存在諸多差異，影響了篩查效果的可比性和一致性。為此，我們制定了《中國(guó)人群肝癌篩查指南》，旨在為臨床醫(yī)生、公共衛(wèi)生工作者和廣大民眾提供科學(xué)、規(guī)范、實(shí)用的肝癌篩查依據(jù)。Livercancer,asahighlyprevalentandlethalmalignanttumorworldwide,earlyscreeninganddiagnosisarecrucialforimprovingthesurvivalrateandqualityoflifeofpatients.Inrecentyears,withthecontinuousadvancementofmedicaltechnologyandadeeperunderstandingoftheepidemiologicalcharacteristicsoflivercancer,China'slivercancerscreeningworkhasmadesignificantprogress.However,duetothelackofunifiedscreeningstandardsandguidelines,therearestillmanydifferencesinpracticaloperationsindifferentregions,whichaffectsthecomparabilityandconsistencyofscreeningresults.Tothisend,wehavedevelopedthe"GuidelinesforLiverCancerScreeningintheChinesePopulation",aimingtoprovidescientific,standardized,andpracticalbasisforlivercancerscreeningforclinicaldoctors,publichealthworkers,andthegeneralpublic.本指南基于國(guó)內(nèi)外最新的肝癌流行病學(xué)數(shù)據(jù)、診斷技術(shù)進(jìn)展和臨床實(shí)踐經(jīng)驗(yàn)，結(jié)合我國(guó)人群肝癌發(fā)病特點(diǎn)，系統(tǒng)地闡述了肝癌篩查的目標(biāo)人群、篩查方法、篩查間隔、診斷流程和管理策略等方面的內(nèi)容。我們希望通過(guò)本指南的推廣和應(yīng)用，能夠推動(dòng)我國(guó)肝癌篩查工作的規(guī)范化、標(biāo)準(zhǔn)化和科學(xué)化，為降低肝癌發(fā)病率和死亡率、提高患者生存質(zhì)量作出積極貢獻(xiàn)。Thisguideisbasedonthelatestepidemiologicaldata,diagnostictechnologyprogress,andclinicalpracticeexperienceoflivercancerbothdomesticallyandinternationally.CombiningwiththecharacteristicsoflivercancerincidenceintheChinesepopulation,itsystematicallyelaboratesonthetargetpopulation,screeningmethods,screeningintervals,diagnosticprocesses,andmanagementstrategiesoflivercancerscreening.Wehopethatthroughthepromotionandapplicationofthisguide,wecanpromotethestandardization,standardizationandscientizationoflivercancerscreeninginChina,andmakepositivecontributionstoreducingtheincidencerateandmortalityoflivercancerandimprovingthequalityoflifeofpatients.在接下來(lái)的章節(jié)中，我們將詳細(xì)介紹肝癌篩查的相關(guān)概念、流行病學(xué)背景、篩查方法的選擇與評(píng)價(jià)、篩查流程的設(shè)計(jì)與實(shí)施以及篩查結(jié)果的管理與隨訪等內(nèi)容。我們期望通過(guò)全面而深入的探討，為廣大讀者提供一份全面、系統(tǒng)、實(shí)用的肝癌篩查指南，為肝癌防控工作提供有力支持。Inthefollowingchapters,wewillprovideadetailedintroductiontotherelevantconcepts,epidemiologicalbackground,selectionandevaluationofscreeningmethods,designandimplementationofscreeningprocesses,andmanagementandfollow-upofscreeningresultsforlivercancerscreening.Wehopetoprovidereaderswithacomprehensive,systematic,andpracticallivercancerscreeningguidethroughcomprehensiveandin-depthdiscussions,andtoprovidestrongsupportforlivercancerpreventionandcontrolwork.二、肝癌風(fēng)險(xiǎn)因素Riskfactorsforlivercancer肝癌的發(fā)生和發(fā)展是一個(gè)多因素、多步驟的復(fù)雜過(guò)程，涉及多種內(nèi)外因素的交互作用。在中國(guó)人群中，肝癌的風(fēng)險(xiǎn)因素主要包括以下幾個(gè)方面：Theoccurrenceanddevelopmentoflivercancerisacomplexprocesswithmultiplefactorsandsteps,involvingtheinteractionofmultipleinternalandexternalfactors.IntheChinesepopulation,theriskfactorsforlivercancermainlyincludethefollowingaspects:病毒性肝炎：乙型肝炎病毒（HBV）和丙型肝炎病毒（HCV）感染是中國(guó)肝癌的主要病因。長(zhǎng)期的慢性肝炎病毒感染會(huì)導(dǎo)致肝臟炎癥、纖維化，最終進(jìn)展為肝硬化和肝癌。Viralhepatitis:HepatitisBvirus(HBV)andhepatitisCvirus(HCV)infectionsarethemaincausesoflivercancerinChina.Longtermchronichepatitisvirusinfectioncanleadtoliverinflammationandfibrosis,ultimatelyprogressingtocirrhosisandlivercancer.肝硬化：肝硬化是肝癌的重要前驅(qū)病變，多種原因均可導(dǎo)致肝硬化，如病毒性肝炎、酒精性肝病、非酒精性脂肪性肝病等。肝硬化患者的肝癌風(fēng)險(xiǎn)顯著增加，因此早期診斷和治療肝硬化對(duì)預(yù)防肝癌具有重要意義。Cirrhosis:Cirrhosisisanimportantprecursortolivercancer,whichcanbecausedbyvariousfactorssuchasviralhepatitis,alcoholicliverdisease,non-alcoholicfattyliverdisease,etc.Theriskoflivercancersignificantlyincreasesinpatientswithlivercirrhosis,thereforeearlydiagnosisandtreatmentoflivercirrhosisareofgreatsignificanceforpreventinglivercancer.黃曲霉素暴露：黃曲霉素是一種強(qiáng)致癌物，主要污染霉變的糧油及其制品。長(zhǎng)期低劑量暴露于黃曲霉素會(huì)增加肝癌的風(fēng)險(xiǎn)，因此避免食用霉變食物、提高糧食儲(chǔ)存條件等是預(yù)防肝癌的重要措施。Exposuretoaflatoxin:aflatoxinisastrongcarcinogenthatmainlycontaminatesmoldygrains,oils,andtheirproducts.Longtermlow-doseexposuretoaflatoxinincreasestheriskoflivercancer,thereforeavoidingtheconsumptionofmoldyfoodandimprovingfoodstorageconditionsareimportantmeasurestopreventlivercancer.飲酒：長(zhǎng)期大量飲酒會(huì)導(dǎo)致酒精性肝病，進(jìn)而增加肝癌的風(fēng)險(xiǎn)。適量飲酒或避免飲酒對(duì)預(yù)防肝癌具有積極意義。Alcoholconsumption:Longtermheavydrinkingcanleadtoalcoholicliverdisease,therebyincreasingtheriskoflivercancer.Moderateoravoidanceofalcoholconsumptionhaspositivesignificanceinpreventinglivercancer.遺傳因素：肝癌的發(fā)生具有一定的家族聚集性，遺傳因素在肝癌的發(fā)病中起著重要作用。有肝癌家族史的人群應(yīng)定期進(jìn)行肝癌篩查，以便早期發(fā)現(xiàn)和治療。Geneticfactors:Theoccurrenceoflivercancerhasacertaindegreeoffamilialclustering,andgeneticfactorsplayanimportantroleintheonsetoflivercancer.Peoplewithafamilyhistoryoflivercancershouldundergoregularlivercancerscreeningforearlydetectionandtreatment.其他因素：吸煙、肥胖、糖尿病、高血壓等因素也可能與肝癌的發(fā)生有關(guān)。這些因素的預(yù)防和控制對(duì)于降低肝癌風(fēng)險(xiǎn)同樣具有重要意義。Otherfactors:smoking,obesity,diabetes,hypertensionandotherfactorsmayalsoberelatedtotheoccurrenceoflivercancer.Thepreventionandcontrolofthesefactorsareequallyimportantforreducingtheriskoflivercancer.肝癌的風(fēng)險(xiǎn)因素涉及多個(gè)方面，包括病毒性肝炎、肝硬化、黃曲霉素暴露、飲酒、遺傳因素等。了解和避免這些風(fēng)險(xiǎn)因素，對(duì)于預(yù)防肝癌的發(fā)生和發(fā)展具有重要意義。定期進(jìn)行肝癌篩查，早期發(fā)現(xiàn)和治療肝癌，也是降低肝癌死亡率的關(guān)鍵措施。Theriskfactorsforlivercancerinvolvemultipleaspects,includingviralhepatitis,cirrhosis,exposuretoaflatoxin,alcoholconsumption,geneticfactors,etc.Understandingandavoidingtheseriskfactorsisofgreatsignificanceforpreventingtheoccurrenceanddevelopmentoflivercancer.Regularlivercancerscreening,earlydetectionandtreatmentoflivercancer,isalsoakeymeasuretoreducelivercancermortality.三、肝癌篩查方法Screeningmethodsforlivercancer肝癌的篩查方法主要包括血清學(xué)檢測(cè)、影像學(xué)檢查以及病理學(xué)檢查。血清學(xué)檢測(cè)中，甲胎蛋白（AFP）是最常用的腫瘤標(biāo)志物，其升高通常提示肝癌的可能性。然而，需要注意的是，AFP的特異性并不強(qiáng)，部分良性肝病也可能導(dǎo)致其升高。因此，在篩查過(guò)程中，應(yīng)結(jié)合其他指標(biāo)如異常凝血酶原（DCP）、甲胎蛋白異質(zhì)體（AFP-L3）等進(jìn)行綜合判斷。Thescreeningmethodsforlivercancermainlyincludeserologicaltesting,imagingexamination,andpathologicalexamination.Inserologicaltesting,alphafetoprotein(AFP)isthemostcommonlyusedtumormarker,anditselevationusuallyindicatesthepossibilityoflivercancer.However,itshouldbenotedthatthespecificityofAFPisnotstrong,andsomebenignliverdiseasesmayalsoleadtoitselevation.Therefore,inthescreeningprocess,otherindicatorssuchasabnormalprothrombin(DCP)andalphafetoproteinheterogeneity(AFP-L3)shouldbecombinedforcomprehensivejudgment.影像學(xué)檢查在肝癌的篩查中起著至關(guān)重要的作用。超聲檢查因其無(wú)創(chuàng)、便捷、經(jīng)濟(jì)等優(yōu)點(diǎn)，被廣泛應(yīng)用于肝癌的初步篩查。然而，超聲檢查受操作者經(jīng)驗(yàn)和技術(shù)水平影響較大，且對(duì)小于1cm的肝癌病灶檢出率較低。因此，對(duì)于疑似肝癌的患者，通常需要進(jìn)行增強(qiáng)CT或MRI檢查以進(jìn)一步明確診斷。這些影像學(xué)檢查方法能夠更準(zhǔn)確地顯示肝癌病灶的大小、位置以及與周圍組織的關(guān)系。Imagingexaminationsplayacrucialroleinthescreeningoflivercancer.Ultrasoundexaminationiswidelyusedinthepreliminaryscreeningoflivercancerduetoitsadvantagesofnon-invasive,convenient,andeconomical.However,ultrasoundexaminationisgreatlyinfluencedbytheoperator'sexperienceandtechnicallevel,andthedetectionrateforlivercancerlesionssmallerthan1cmisrelativelylow.Therefore,forpatientssuspectedoflivercancer,enhancedCTorMRIexaminationisusuallyrequiredtofurtherclarifythediagnosis.Theseimagingexaminationmethodscanmoreaccuratelydisplaythesize,location,andrelationshipwithsurroundingtissuesoflivercancerlesions.病理學(xué)檢查是肝癌診斷的金標(biāo)準(zhǔn)。對(duì)于通過(guò)血清學(xué)檢測(cè)和影像學(xué)檢查懷疑為肝癌的患者，應(yīng)進(jìn)行病理學(xué)檢查以明確診斷。常用的病理學(xué)檢查方法包括細(xì)針穿刺活檢和手術(shù)切除活檢。細(xì)針穿刺活檢創(chuàng)傷小，但可能因取材不足或出血等原因?qū)е略\斷困難。手術(shù)切除活檢雖然創(chuàng)傷較大，但能夠獲取足夠的組織樣本進(jìn)行病理學(xué)檢查，從而更準(zhǔn)確地診斷肝癌。Pathologicalexaminationisthegoldstandardforthediagnosisoflivercancer.Forpatientssuspectedoflivercancerthroughserologicalandimagingtests,pathologicalexaminationshouldbeperformedtoconfirmthediagnosis.Thecommonlyusedpathologicalexaminationmethodsincludefineneedleaspirationbiopsyandsurgicalresectionbiopsy.Fineneedleaspirationbiopsyhasminimaltrauma,butmaybedifficulttodiagnoseduetoinsufficientsamplingorbleeding.Althoughsurgicalresectionbiopsymaycausesignificanttrauma,itcanobtainsufficienttissuesamplesforpathologicalexamination,thusprovidingamoreaccuratediagnosisoflivercancer.肝癌的篩查需要結(jié)合血清學(xué)檢測(cè)、影像學(xué)檢查和病理學(xué)檢查等多種方法。在實(shí)際操作中，應(yīng)根據(jù)患者的具體情況選擇合適的篩查方法，以提高肝癌的早期診斷率和治療效果。隨著醫(yī)學(xué)技術(shù)的不斷進(jìn)步，新的篩查方法和技術(shù)也將不斷涌現(xiàn)，為肝癌的早期診斷和治療提供更多的選擇和可能性。Thescreeningoflivercancerrequiresacombinationofvariousmethodssuchasserologicaltesting,imagingexamination,andpathologicalexamination.Inpracticaloperation,appropriatescreeningmethodsshouldbeselectedbasedonthespecificsituationofpatientstoimprovetheearlydiagnosisrateandtreatmenteffectoflivercancer.Withthecontinuousadvancementofmedicaltechnology,newscreeningmethodsandtechnologieswillcontinuetoemerge,providingmorechoicesandpossibilitiesfortheearlydiagnosisandtreatmentoflivercancer.四、肝癌篩查策略Livercancerscreeningstrategy肝癌篩查策略的制定對(duì)于我國(guó)肝癌防控工作至關(guān)重要。針對(duì)中國(guó)人群肝癌的流行病學(xué)特征，結(jié)合現(xiàn)有的篩查技術(shù)和資源，我們提出以下肝癌篩查策略。ThedevelopmentoflivercancerscreeningstrategiesiscrucialforthepreventionandcontroloflivercancerinChina.BasedontheepidemiologicalcharacteristicsoflivercancerintheChinesepopulationandexistingscreeningtechnologiesandresources,weproposethefollowinglivercancerscreeningstrategies.目標(biāo)人群：肝癌篩查應(yīng)重點(diǎn)關(guān)注高危人群，包括慢性乙型肝炎（CHB）和慢性丙型肝炎（CHC）患者、肝硬化患者、長(zhǎng)期大量飲酒者、肝癌家族史者以及其他肝臟疾病患者。對(duì)于生活在肝癌高發(fā)地區(qū)的人群，也應(yīng)加強(qiáng)篩查力度。Targetaudience:Livercancerscreeningshouldfocusonhigh-riskgroups,includingpatientswithchronichepatitisB(CHB)andchronichepatitisC(CHC),livercirrhosis,long-termheavydrinkers,familyhistoryoflivercancer,andotherliverdiseasepatients.Forpeoplelivinginareaswithhighincidenceoflivercancer,screeningeffortsshouldalsobestrengthened.篩查方法：目前，肝癌篩查的主要方法包括血清甲胎蛋白（AFP）檢測(cè)和肝臟超聲檢查。AFP作為肝癌的特異性標(biāo)志物，對(duì)于肝癌的早期發(fā)現(xiàn)具有重要價(jià)值。肝臟超聲檢查可以直觀顯示肝臟的形態(tài)、結(jié)構(gòu)和血流情況，有助于發(fā)現(xiàn)肝臟占位性病變。對(duì)于AFP和肝臟超聲檢查均疑似肝癌的患者，應(yīng)進(jìn)一步進(jìn)行CT或MRI等影像學(xué)檢查以明確診斷。Screeningmethods:Currently,themainmethodsforlivercancerscreeningincludeserumalphafetoprotein(AFP)detectionandliverultrasoundexamination.AFP,asaspecificmarkerforlivercancer,hasimportantvalueforearlydetectionoflivercancer.Liverultrasoundexaminationcanvisuallydisplaythemorphology,structure,andbloodflowoftheliver,whichhelpstodetectliverspaceoccupyinglesions.ForpatientssuspectedoflivercancerthroughbothAFPandliverultrasoundexaminations,furtherimagingexaminationssuchasCTorMRIshouldbeperformedtoconfirmthediagnosis.篩查間隔：針對(duì)高危人群，建議每6個(gè)月至1年進(jìn)行一次肝癌篩查。對(duì)于一般人群，建議每2年進(jìn)行一次篩查。具體篩查間隔應(yīng)根據(jù)個(gè)體情況、篩查方法和醫(yī)療資源等因素綜合考慮。Screeninginterval:Forhigh-riskpopulations,itisrecommendedtoundergolivercancerscreeningevery6monthsto1year.Forthegeneralpopulation,itisrecommendedtoundergoscreeningevery2years.Thespecificscreeningintervalshouldbecomprehensivelyconsideredbasedonindividualconditions,screeningmethods,andmedicalresources.篩查管理：建立完善的肝癌篩查管理體系，包括篩查登記、隨訪追蹤、質(zhì)量控制和數(shù)據(jù)統(tǒng)計(jì)等方面。通過(guò)定期監(jiān)測(cè)和評(píng)估篩查效果，不斷優(yōu)化篩查策略，提高肝癌的早期發(fā)現(xiàn)率和治愈率。Screeningmanagement:Establishacomprehensivelivercancerscreeningmanagementsystem,includingscreeningregistration,follow-uptracking,qualitycontrol,anddatastatistics.Byregularlymonitoringandevaluatingtheeffectivenessofscreening,continuouslyoptimizingscreeningstrategies,andimprovingtheearlydetectionandcureratesoflivercancer.健康教育：加強(qiáng)肝癌防治知識(shí)的宣傳教育，提高公眾對(duì)肝癌的認(rèn)知度和自我保健意識(shí)。通過(guò)廣泛宣傳肝癌篩查的重要性和方法，鼓勵(lì)高危人群積極參與篩查，降低肝癌的發(fā)病率和死亡率。Healtheducation:Strengthenthepromotionandeducationoflivercancerpreventionandtreatmentknowledge,improvepublicawarenessoflivercancerandself-careawareness.Bywidelypublicizingtheimportanceandmethodsoflivercancerscreening,encouragehigh-riskgroupstoactivelyparticipateinthescreening,andreducetheincidencerateandmortalityoflivercancer.制定針對(duì)中國(guó)人群肝癌篩查策略，需要綜合考慮流行病學(xué)特征、篩查方法、醫(yī)療資源等多方面因素。通過(guò)實(shí)施有效的篩查策略，可以提高肝癌的早期發(fā)現(xiàn)率和治愈率，降低肝癌對(duì)人群健康的危害。DevelopingalivercancerscreeningstrategyfortheChinesepopulationrequirescomprehensiveconsiderationoffactorssuchasepidemiologicalcharacteristics,screeningmethods,andmedicalresources.Byimplementingeffectivescreeningstrategies,theearlydetectionandcureratesoflivercancercanbeimproved,andtheharmoflivercancertopopulationhealthcanbereduced.五、肝癌篩查質(zhì)量控制Qualitycontroloflivercancerscreening肝癌篩查的質(zhì)量控制是確保篩查準(zhǔn)確性和有效性的關(guān)鍵環(huán)節(jié)。在《中國(guó)人群肝癌篩查指南》中，我們強(qiáng)調(diào)以下幾點(diǎn)以保障篩查質(zhì)量。Thequalitycontroloflivercancerscreeningisakeylinktoensuretheaccuracyandeffectivenessofscreening.IntheChinesePopulationLiverCancerScreeningGuidelines,weemphasizethefollowingpointstoensurethequalityofscreening.篩查人員的專業(yè)培訓(xùn)是至關(guān)重要的。所有參與篩查的醫(yī)生、護(hù)士和技術(shù)人員都應(yīng)接受肝癌相關(guān)知識(shí)的培訓(xùn)，包括但不限于肝癌的流行病學(xué)、臨床表現(xiàn)、影像學(xué)特征以及篩查方法的選擇和應(yīng)用。定期的復(fù)訓(xùn)和考核也是必要的，以確保篩查人員能夠不斷更新知識(shí)，提高篩查技能。Professionaltrainingforscreeningpersonneliscrucial.Alldoctors,nurses,andtechniciansinvolvedinscreeningshouldreceivetrainingonlivercancerrelatedknowledge,includingbutnotlimitedtotheepidemiology,clinicalmanifestations,imagingfeatures,andselectionandapplicationofscreeningmethodsforlivercancer.Regularretrainingandassessmentarealsonecessarytoensurethatscreeningpersonnelcancontinuouslyupdatetheirknowledgeandimprovetheirscreeningskills.篩查設(shè)備的選擇和維護(hù)也是質(zhì)量控制的重要環(huán)節(jié)。應(yīng)選用經(jīng)過(guò)國(guó)家認(rèn)證、性能穩(wěn)定的設(shè)備，并定期進(jìn)行設(shè)備的校準(zhǔn)和維護(hù)，確保設(shè)備的準(zhǔn)確性和可靠性。同時(shí)，篩查過(guò)程中應(yīng)遵循設(shè)備操作規(guī)范，避免因操作不當(dāng)導(dǎo)致的結(jié)果偏差。Theselectionandmaintenanceofscreeningequipmentarealsoimportantaspectsofqualitycontrol.Nationalcertifiedandstableequipmentshouldbeselected,andregularcalibrationandmaintenanceshouldbecarriedouttoensuretheaccuracyandreliabilityoftheequipment.Atthesametime,thescreeningprocessshouldfollowtheequipmentoperationspecificationstoavoidresultdeviationscausedbyimproperoperation.再次，篩查流程的優(yōu)化也是提高篩查質(zhì)量的關(guān)鍵。應(yīng)制定詳細(xì)的篩查流程，包括篩查前的準(zhǔn)備、篩查過(guò)程中的注意事項(xiàng)以及篩查后的結(jié)果處理等方面。同時(shí)，應(yīng)建立篩查質(zhì)量控制機(jī)制，對(duì)篩查過(guò)程進(jìn)行全程監(jiān)控，及時(shí)發(fā)現(xiàn)并糾正存在的問(wèn)題。Onceagain,optimizingthescreeningprocessisalsothekeytoimprovingthequalityofscreening.Adetailedscreeningprocessshouldbeestablished,includingpreparationbeforescreening,precautionsduringthescreeningprocess,andhandlingofresultsafterscreening.Atthesametime,ascreeningqualitycontrolmechanismshouldbeestablishedtomonitortheentirescreeningprocess,promptlyidentifyandcorrectexistingproblems.肝癌篩查的質(zhì)量評(píng)估也是必不可少的。應(yīng)定期對(duì)篩查結(jié)果進(jìn)行質(zhì)量評(píng)估，包括篩查的陽(yáng)性率、漏診率、誤診率等指標(biāo)。通過(guò)質(zhì)量評(píng)估，可以發(fā)現(xiàn)篩查過(guò)程中存在的問(wèn)題和不足，進(jìn)而采取相應(yīng)措施進(jìn)行改進(jìn)，提高篩查質(zhì)量。Thequalityevaluationoflivercancerscreeningisalsoessential.Regularqualityevaluationofscreeningresultsshouldbeconducted,includingindicatorssuchaspositiverate,mis
