放疗科

放射治疗是恶性肿瘤的重要治疗手段，天津市胸科医院放疗科配备了飞利浦大孔径CT、Pinnacle3治疗计划系统、医科达SynergyIGRT医用直线加速器、IBA三维水箱及调强验证等设备，主要涉及胸部恶性肿瘤(肺癌、食管癌、恶性胸腺瘤等)的治疗。1、术前放疗或放化疗可以提高部分肺癌、食管癌、恶性胸腺瘤胸腺癌等患者的手术切除率，降低局部复发率提高生存率。2、术后肿瘤残存、切缘阳性或纵隔淋巴结转移的胸部恶性肿瘤患者采用术后放化疗可以降低局部复发率提高生存率，对于浸润性胸腺瘤及胸腺癌患者术后均应给予根治性放疗。3、因为某些原因不能手术的早期肺癌患者，实施立体定向照射可以获得与手术相似的疗效。局部晚期非小细胞肺癌患者同步放化疗的效果优于序贯放化疗。局限期小细胞肺癌患者应给予放化疗等，广泛期患者以化疗为主，选择性脑预防照射能够降低小细胞肺癌患者的脑转移率。晚期无法手术的恶性胸腺瘤及胸腺癌患者采用放化疗等综合治疗可以取得较好的疗效。4、局部晚期食管癌患者可予以同步或贯序放化疗。5、局部晚期纵膈肿瘤患者可予以放化疗。6、放射治疗是一种毒副反应较小且有效的局部治疗方法，对于年龄较大无手术、化疗指征的胸部恶性肿瘤患者放疗也不失为一种有效的治疗手段。7、对各种恶性肿瘤的转移性病灶(脑转移骨转移等)通过姑息性放疗可以不同程度的减轻症状、预防并发症、改善患者的生存质量等。结合我院的诊疗特色，为更好地为胸部肿瘤患者提供诊疗方案，我院放疗科预计开展以下检查及治疗项目:三维适形放疗(3DCRT)，调强放疗(IMRT)，立体定向放疗(X刀)，图像引导放疗等技术。Radiationtherapyisanimportanttreatmentformalignanttumor.TianjinChestHospitalradiotherapydepartmentisequippedwithPhilipslargeapertureCT,thePinnacle3TPS,ElektaSynergyIGRTmedicallinearaccelerator,theIBABluePhantom3DWaterphantomSystemandtheIMRTVerificationequipmentsetc,mainlyrelatedtothoracicmalignanttumor(suchaslungcancer,esophagealcancer,malignantthymomaetc.)treatment.1.Preoperativeradiotherapyorchemoradiotherapycaneffectivelyimprovethepatients’surgicalresectionofthoracicmalignanttumors.Inthemeanwhile,itcanreducelocalrecurrenceandimprovesurvival.2.Postoperativeradiotherapyisgivenforpatientswithpositive-marginorpathologicmediastinallymphnodemetastasisdisease.3.Stereotacticradiosurgeryisagoodoptionformedicallyinoperablepatientswithearlystagenon-smallcelllungcancer(NSCLC).EffectisbetterthantheconcurrentchemoradiotherapyandsequentialinPatientswithlocallyadvancedNSCLC.ForSmallcelllungcancer(SCLC),definitivechemoradiationisusuallyemployedforlimited-stageSCLCorextensive-stageSCLCwithgoodresponsetochemotherapy.Prophylacticcranialirradiation(PCI)isindicatedforallstagesofSCLCafterresponsetoprimarytherapy.4.Definitivechemoradiationcuressomepatientswithesophagealcancer.PatientswithLocaladvancedesophagealcarcinomamaybeconcurrentchemoradiotherapyorsequential.5.Radiationtherapyshouldbegivenforpatientswithunresectableorincompletelyresectedinvasivethymomaorthymiccarcinoma.6.Radiotherapyisakindoflesstoxicityreactionandeffectivelocaltreatment.Radiotherapyisalsoaneffectivetreatmentformedicallyinoperableandnochemotherapypatientswiththoracicmalignanttumor.7.Palliativeradiationisoftenneededforsymptomaticpatients(withobstructionpneumonia,superiorvenacavasyndrome,etc)fromprimarydiseasewithpoorperformancestatus,recurrentdisease,andmetastaticdisease(brainandbonemetastases).Tocombinewithourhospitalfeaturesandprovidebettertherapeuticstrategytothoraciccancerpatients,ourdepartmentdeliversabroadrangeofradiationtherapyservicestopatients,including3-dimensionalconformalradiationtherapy(3DCRT),intensitymodulatedradiationtherapy(IMRT),stereotacticradiosurgery,usingimage-guidedradiationtherapy(IGRT)inradiotherapy,etc.
