Description
技术领域
本发明涉及用于固定放疗患者的装置和方法。
背景技术
全乳放疗是可在浸润性乳腺癌的局部切除(***肿瘤切除术)之后进行的治疗。辅助放疗的一个基本原理是:通过除去原发肿瘤区域内的残余癌灶和远离***的区域内假定的隐匿性多中心疾病,来减小乳腺癌的复发率。然而,乳腺放疗之后同一***中大多数的癌症复发都是发生在和初始肿瘤相同的象限内。事实上,乳腺放疗后大约80-90%的乳腺癌复发都是发生在***肿瘤切除术疤痕的附近。因此,更明确地针对癌变***区域的治疗对于使乳腺癌复发最小化可同样有效。

具体实施方式
下面将参照附图描述本发明的实施方式,全部附图中相似的附图标号表示相似的元件。因为本说明书中使用的术语是结合对本发明某些具体实施方式的详细描述而使用的,因此其不趋向于以任何限制性的方式解释。此外,本发明的实施方式可包括若干新颖的特征,其中的任何一个都不仅仅负责其可期望的属性,也不是执行本发明所必须的。
图1是放疗***100的一个实施方式的侧视图。示例性的放疗***100被设计用于将放疗剂量释放至患者108(例如,癌症患者108)的目标区域,用于从相对于患者108的一个或多个角度或方向进行恶性或其他条件下的治疗。
在一个实施方式中,放疗***100被设计用于将质子束治疗剂量释放至患者的目标区域。题为“Multi-Station Proton Beam TherapySystem”的第4,870,287号美国专利对这种质子放射***的结构和操作进行了详细描述,其全部内容通过引用并入本文。在其它实施方式中,***100被设计用于释放本领域已知的临床适用的任何其它形式的辐射,例如,x射线、伽马射线、强子、中子等。
在某些实施方式中,放疗***100可包括患者治疗站和托台102,托台102包括大致为半球形或截头圆锥体形的支撑架,用于附接或支撑放疗***100的其它组件。题目均为“Roller-Supported,Modular,Isocentric Gentry and Method of Assembly”的第4,917,344和5,039,057号美国专利对托台102的结构和操作进行了详细描述,其全部内容均通过引用并入本文。
示例性的***100还包括喷嘴110,其附接于托台102并由托台102支撑,从而喷嘴110可绕托台等中心120相对精确地旋转。***100包括放射源106,其释放例如加速质子束的治疗束,治疗束穿过位于喷嘴110远端的开孔并由该开孔成形。示例性的束路径由标号146表示。在一个实施方式中,可根据患者具体的治疗放疗处方对开孔进行调节。在其它实施方式中,可使用其它的托台配置将放射束导向患者108。
在图1的实施方式中,***100还包括一个或多个成像器112,在此实施方式中,成像器112相对于托台102可在伸出位置和缩回位置之间伸缩。如图1所示,成像器112位于伸出位置。在一个实施方式中,成像器112包括固态非晶硅x射线成像器,其可例如根据穿过患者身体的入射x射线辐射对图像信息进行显影。***100还可包括x射线源,其被配置为发射适当的x射线辐射穿过***的患者组织,以经由成像器112生成***材料的射线图像。成像器112的可伸缩性提供了这样的有益效果,即,在不需要成像器112时能够将成像器从放射源106的束路径缩回,从而在托台102外壳内提供额外的间隙,并且,能够将成像器112放置在放射源102的潜在有害发射物的路径之外,从而可减小对提供至成像器112的防护的需要。在此实施方式中,成像器和放射源130被设置为正交的,以从两个方向提供患者的射线图像。
示例性的***100还包括患者***114和附接于患者***114的患者支撑结构130,也称为纵槽(pod)130。在一个实施方式中,患者***114适于在接收适当的移动命令之后将患者支撑结构130定位于多个平移轴和旋转轴,并可将患者支撑结构130定位于三个正交的平移轴(例如,纵向的、垂直的和横向的)和三个正交旋转轴(例如,倾斜、滚动或侧转),以对患者支撑结构130的放置提供全部六个运动自由度。如图1所示,患者在支撑结构130上定位为仰卧(脸朝上)位置。
在某些实施方式中,例如下文将进一步详细描述的实施方式中,固定装置可定位在支撑结构130上并成形为与具体患者的身体的轮廓相接。这样,在图1的实施方式中,固定装置可***在支撑结构130和患者108之间。在一个实施方式中,该固定装置包括一个或多个豆袋(beanbag)或泡沫珠垫,例如由Med-Tec公司生产的VAC-LOKTM泡沫珠垫。在另一实施方式中,固定装置包括两部分的可膨胀泡沫,例如,由Med-Tec公司生产的一个或多个泡沫产品、速凝高分子泡沫、或其它适当的固定物质。在其它的实施方式中,固定装置例如包括垫座、衬垫和/或豆袋。使用形成以与患者身体的轮廓吻合的固定装置可有利地减少患者的移动,从而允许放疗计划减少被放射的目标区域周围的组织的量。
尽管以下描述不断地提到患者定位***100,但本文描述的改进的装置和方法可与各种其它的患者定位***一起使用。例如,本文描述的装置和方法可与其它自动的、半自动的、与***控制器直接相接的手动控制的、或全手动的(例如,用手柄释放制动器和移动每个装置轴)定位***一起使用。因此,本文讨论的***和方法适用于与任何其它放疗装置和设备一起使用。
放疗***100可用于将放疗释放至患者的任何部位,包括患者的一个或两个***。尽管***100可用于对患者提供全乳辐射,但是,提供部分乳腺放疗(由此减少对整个***进行辐射所带来的副作用)的***和方法可对患者***的癌症区域(或其他治疗区域)提供有效的辅助治疗,同时使被治疗的***的癌症复发最小化。更特别地,通过将治疗限制在与***治疗区域(例如,***肿瘤切除术空腔)临近的有限量的***组织,可减少暴露于放疗的正常组织的量,从而潜在地减少急性和慢性毒性。此外,较小的目标体积可允许使用减少保乳治疗的时间和不便的大分割的治疗方案,可用***的化疗使时间安排问题最小化,并通过减小局部治疗的延迟潜在地改善了效果。在其他已知的或之后开发出的技术中,部分乳腺放疗例如可包括术后的间质内放疗、对***肿瘤切除术空腔的腔内放疗、和/或利用3D适形技术用光子进行的外束放疗。
质子治疗可证明对执行部分乳腺照射是有用的。与用x射线的三维适形放疗相比,固有较好的深度剂量特性(布拉格峰)使释放至周围正常组织(尤其是肺部、心脏、胸壁和治疗***)的累积剂量最小化。例如,质子束的物理特性允许精确的束以任何给定的深度和形状停止在组织内,这就可允许减少释放至正常组织的累积剂量。此外,其还允许以非常均匀的剂量分布释放高度适形的剂量,从而从治疗区域内消除“热点”。此外,质子疗法是无创的且不需要破坏***皮肤,这就可产生改善的美容效果。因此,本文描述的固定装置和方法可与质子疗法方案和释放结合使用,也可和其它类型的放射方案和释放装置结合使用。
如本领域技术人员将认识到的那样,患者(更具体地,患者的治疗区域)的固定级别至少部分地基于被照射的治疗区域的大小来确定。例如,如果将患者完全固定以使治疗区域不能移动,则可仅照射该治疗区域,而不包括治疗计划内任何周围的组织。因此,通过改善对***的固定,可减小部分乳腺治疗方案中的照射区域。
不同的患者在呼吸时***的移动也不相同。因此,即使治疗的***被固定,由于正常呼吸引起的患者肺部的移动,其***仍然会有一定量的移动。因此,如果***的移动可减小,***的治疗区域则可进一步减小。
根据本文描述的改进的***和方法,可将患者固定以使被治疗的***精确地回到对每个放疗已知的位置。此外,改进的***和方法减少了***的呼吸运动。因此,本文描述的固定装置和技术提供了精确的可再现的***定位,同时消除了呼吸运动。通过提供精确可再现的***定位并减少呼吸运动,本文描述的***和方法能够对患者***的减小的治疗区域进行治疗。
图2A是示例性的患者支撑结构200的等距图,图2B是支撑结构200中的***固定装置210的等距图,其中,***固定装置210被配置为固定放疗患者的左乳。
在图2A和2B的实施方式中,***固定装置210包括两部分的可膨胀泡沫,其绕俯卧(脸朝下)的患者的一部分已被硬化。例如,患者可位于支撑结构200中,其***与支撑结构200的底面205之间具有微小的间隙。然后,可将该两部分的泡沫倾倒或以其它方式放置在患者的***区域周围,并允许其在***周围硬化,从而***轮廓在硬化的泡沫中反映为负凸起。因此,例如与仅有支撑结构200相比,患者的***可由轮廓化后的***固定装置210更完整地支撑。此外,由于固定装置210与俯卧的患者相配,因此,与仰卧的患者经受的呼吸运动相比,治疗***的呼吸运动被最小化。这样,利用定制模制的固定装置210,***固定装置不仅允许患者可重复地位于支撑结构200内,俯卧的用户还能表现出其治疗***具有较少的呼吸运动。
在一个实施方式中,在形成***固定装置210之前,用垫座、豆袋、泡沫结构(例如泡沫珠真空垫)和/或其他支撑结构支撑患者的肩部、腹部和/或盆骨。在此实施方式中,当患者正确地位于泡沫珠真空垫上时,例如在***区域周围形成开口,该开口例如可用两部分的可膨胀泡沫,以形成***固定装置210。在一个实施方式中,可在将两部分的泡沫布置在***区域周围之前将空气从真空垫中去除,以对头部、肩部、腹部和/或盆骨区域提供基本刚性的固定,同时在***和支撑面200之间留有打开的空间。这样,在患者的胸部区域周围形成固定装置210之后,支撑装置200被填充有支撑患者腿部、头部和手臂的一个或多个垫座、豆袋或泡沫结构,同时患者的胸部区域由包括可膨胀泡沫或类似材料的***固定装置210支撑。在一个实施方式中,***固定装置210可由一个或多个泡沫珠真空垫或适当地符合患者***并提供刚性或半刚性支撑结构的其他材料形成。
图3A示出了示例性的支撑胸罩300,其包括用于支撑放疗患者的治疗***的罩杯310。在一个实施方式中,患者佩戴支撑胸罩300,以进一步固定治疗***和/或重复地将治疗***重新定位于基本类似的位置。在一个实施方式中,罩杯310用刚性或半刚性材料形成,例如,塑料。在某些实施方式中,可根据患者的***大小,将罩杯310替换为各种大小的其它罩杯。例如,可将一系列罩杯交替地附接于带330,以使对应于各种***大小的罩杯大小可用。在一个实施方式中,罩杯310被配置为将治疗***定位于可再现的形状。图3B是示例性的罩杯310的侧视图。
在图3A的实施方式中,支撑胸罩300还包括压缩材料320,其覆盖将不接受放疗的***(本文中称为“对侧***”)。放疗方案通常试图减少释放至放疗区域之外的区域(例如,不趋向于接受放疗的对侧***)的辐射。因此,压缩材料320有利地压缩对侧***,并将被压缩的***定位于远离释放至位于罩杯310内的治疗***的放射束的路径。在一个实施方式中,压缩材料320包括布,当支撑胸罩300绕患者勒紧时,该布足够强韧以将对侧***明显压平在压缩材料320下。在某些实施方式中,支撑胸罩300可包括两个支撑罩杯(例如罩杯310),以将患者的两个***都支撑在可再现的位置。在其它实施方式中,可将罩杯310从胸罩300上去除,例如如图3B所示,并将其连接于两部分的泡沫,从而仅当两部分的泡沫邻近患者时,患者的治疗***才与罩杯吻合。
再次参照图2B,示出的***固定装置210具有与罩杯310的形状相对应的***轮廓220。在此实施方式中,患者佩戴在左乳具有罩杯310的支撑胸罩,从而在***固定装置210形成时,罩杯310的形状反映在固定装置210中。如图2C所示,由于放置在患者右乳上的压缩材料320,因此在***固定装置210的位置230处仅具有非常浅的空腔。这样,在图2C的实施方式中,患者可以下文进一步介绍的方式被固定以进行对左乳的放疗。
图4是制造***固定装置并将患者固定用于部分乳腺放疗的方法的一个实施方式的流程图。图4的示例性方法有利地提供了精确的并可再现的***定位,同时减少了呼吸运动。图4的方法可与任何类型的放疗结合使用,或与对***的其它治疗结合使用,例如全乳照射或部分乳腺照射。根据各实施方式,图4的方法可包括更少的或额外的块,并且该方法可用不同的顺序执行。
从块410开始,制造具有为固定特定患者而定制的轮廓的支撑结构,例如根据图5的方法制造。例如固定装置210的***固定装置可安装在支撑患者其它区域的纵槽或其他支撑结构中。
继续至块420,制定用于向患者释放放疗的治疗方案。该放疗可为任何类型的可用治疗,例如x射线或质子治疗。制定的治疗方案可包括全乳治疗或部分乳腺治疗。在一个实施方式中,由于***固定装置210提供对患者***的可再现固定,因此可增加放疗的效率。因此,在治疗方案中使用***固定装置210可减少向***肿瘤切除术或其他治疗区域的实际放射释放所需的时间。此外,对患者***的改善的固定和(通过将患者置于俯卧姿态)对由呼吸产生的正常运动的减少使得该治疗方案能够减小***的目标区域,并能够减小接收放射的治疗区域周围的组织的量。
在某些实施方式中,使用三维多束质子治疗方案。在一个实施方式中,治疗方案需要三到四个分离的轴向治疗束,其可与各种束加权结合使用。例如,可用适当的开孔、补偿器和束调制,使用质子束进行治疗。在一个实施方式中,对束进行选择以完全不伤害下面的心脏和肺部组织,并避开不用于治疗的***。还可注意不对皮肤造成伤害。
移动至块430,患者例如根据图6的方法被固定用于放疗。在一个实施方式中,使用在块410制造的***固定装置(以及某些实施方式中的支撑结构)将治疗***可重复地定位在和制定治疗方案时基本相同的位置。因为***固定装置被固化并形成为与患者的***(或支撑胸罩的罩杯的外表面)的轮廓贴身吻合,因此,当患者位于支撑结构中时,治疗***被固定在与制造***固定装置时使用的位置基本相同的位置。在当形成***固定装置时患者佩戴支撑胸罩的实施方式中,当患者被固定用于治疗时也要佩戴该支撑胸罩。
接下来,在块440,向患者释放放疗,例如部分乳腺放疗。如上所述,还可向被固定装置固定的患者执行任何其他类型的放疗。
继续至块450,执行医师、放射科医师或其他人员确定是否将额外的剂量释放至患者。在一个实施方式中,该确定主要基于预定的治疗计划,并可在制造固定装置之前进行。例如,放射肿瘤学家可对预定时间周期开出特定的周期性的放射剂量,例如,2-6周内的每天、几个月内的每周一次。在某些实施方式中,对治疗效果进行监控,并可在某些放疗之后对治疗计划进行调整。如果要使用额外的剂量,该方法则返回块430,再次将患者固定,并对固定的患者进行照射(块440)。在一个实施方式中,患者佩戴支撑胸罩,通过利用施加的皮肤标记,支撑胸罩可重复地放置在胸部上。然后,可将患者俯卧在支撑结构上而将其定位于***固定装置中。在某些实施方式中,在每次治疗前执行正交的诊断质量x射线,并将其与数字重构的射线照片比较,以重现治疗计划CT扫描时的身体/***位置。在某些实施方式中,还可使用例如钛夹的夹子用于对准处理,夹子放置在活组织检查空腔或其他解剖学位置的周围。
有利地,连续放疗之间的时间周期以及患者的相关固定可明显变化,而不影响利用***固定装置(可选地,以及支撑胸罩)获得的固定的再生。例如,患者治疗计划可需要每天、每周或每月的治疗。在任何情况下,利用被形成轮廓以支撑俯卧的具体患者***的***固定装置,将患者可再现地固定。如上所述,由于患者处于俯卧姿态,因此,与处于仰卧姿态时的***移动量相比,由呼吸引起的***移动量也可减少。
当不再需要进一步的治疗时,该方法继续至块450,完成治疗。
图5是制造***固定装置(例如,***固定装置210)的示例性方法的流程图。根据各实施方式,图5的方法可包括更少或额外的块,并且这些块可以用与示出的顺序不同的顺序执行。
从块510开始,患者佩戴有支撑胸罩,例如图3A和3B所示的胸罩。在一个实施方式中,支撑胸罩包括与治疗***相吻合的刚性或半刚性罩杯。支撑胸罩被配置为使***可重复地在基本相同的位置重新定位于罩杯内。在某些实施方式中,在形成固定装置时不使用支撑胸罩。在这样的实施方式中,当两部分的泡沫被倾倒至***周围时可将罩杯放置在和/或保持在***上,并在完成两部分的泡沫的硬化之前将罩杯去除。在此实施方式中,罩杯可为固定结构的一部分。在其它实施方式中,当固定装置形成时,患者的皮肤可与两部分的泡沫直接接触。
移动至块520,患者被定位于支撑结构中,例如支撑结构200(图1),在***和纵槽200的底部205之间具有微小的间隙。然而,在其它实施方式中,***可最低程度地接触纵槽200。如果***被过度压缩,例如通过将患者重量的一部分由抵靠纵槽200的底部的***支撑,则***将更接近于患者的内脏,例如心脏和肺部。此外,当特定***区域的位置趋向于对于每次***压缩变化时,将患者精确地重新定位于***被压缩的位置会更加困难。因此,在有利的实施方式中,***被定位为与纵槽200具有微小间隙或与之最低程度地接触。
继续至块530,患者的肩部、腹部和/或盆骨由垫座、豆袋、泡沫结构(例如泡沫珠真空垫)和/或其它支撑结构支撑,同时将***周围的区域保持为暂时不被直接支撑。在此实施方式中,可在将两部分的泡沫布置在***区域周围(块540)之前,将空气从真空垫去除,以对头部、肩部、腹部和/或盆骨区域提供基本刚性的固定。因此,在某些实施方式中,纵槽200至少部分地填充有一个或多个垫座、豆袋、泡沫结构或类似材料。在某些实施方式中,块520和530同时执行,因为支撑结构绕患者的定位有助于将患者的治疗***相对于纵槽200适当定位。
继续至块540,将两部分的泡沫倾倒在患者的***区域周围,并允许其在***周围硬化,以使***的轮廓(或支撑胸罩的轮廓,如果使用的话)反映为硬化泡沫中的负凸出。更特别地,两部分的泡沫最初为具有延展性的,以使其可倾倒在患者胸部周围并基本填充***(或胸罩)周围的空气空间。在一个实施方式中,该两部分的泡沫经历使泡沫固化的化学变化。因此,由于两部分的泡沫在固化之前被布置在***周围,因此,当被固化以形成***固定装置时,泡沫将变成患者***的硬化的模型。该***固定装置允许***保持在悬挂位置,而不是抵靠纵槽200的底面压缩。在一个实施方式中,不使用两部分的泡沫,***固定装置可由一个或多个泡沫珠真空垫或适于符合患者***(和/或支撑胸罩)轮廓的其它材料形成,并提供刚性或半刚性的支撑结构。
图6是示出了固定用于放疗的***的示例性方法的流程图。如上所述,利用患者特定的***固定装置,可将患者精确地且可再现地定位,用于进行放疗,同时使患者处于俯卧姿态,以减小呼吸运动。根据各实施方式,图6的方法可包括更少或额外的块,并且这些块可用与示出的顺序不同的顺序执行。
从块610开始,将用于制造***固定装置的支撑胸罩重新定位在患者身上。在一个实施方式中,利用施加的皮肤标记将支撑胸罩可再现地放置在患者的胸部上。在其它的实施方式中,可使用其它标记(例如小的纹身)将支撑胸罩定位在患者身上的与制造***固定装置时基本相同的位置。
移动至块620,将俯卧的患者定位于包含***固定装置的纵槽内。在一个实施方式中,患者躺在包含***固定装置的纵槽上,以使治疗***放置在该固定装置的相应轮廓中。当患者位于该纵槽上时,可将该纵槽移动至放射释放区域,例如,用于放疗的托台内。
以上说明详细描述了本发明的某些实施方式。然而,显而易见的是,不论上述内容在文字上如何详细描述,本发明可由多种方式实践。仍然如上所述,应该注意到,在描述本发明某些特征和方面时特定术语的使用并不意味着,该术语在本文被重新定义以限制为包括与该术语相关的、本发明的特征或方面的任何具体特性。因此,本发明的范围应该根据权利要求及其等同解释。
