在先前照射的区域中管理孤立的复发性肺癌具有挑战性。在这里,我们描述了支气管内超声 (EBUS) 引导的顺铂注射液,用于治疗在先前放射区域内局部肺癌复发的患者。

该程序的总体目标是描述支气管内超声或 EBUS 引导的顺铂注射,用于治疗在先前放射区域内局部肺癌复发的患者。该方法可以帮助回答肺癌治疗领域的关键问题,即 EBUS 引导下经支气管瘤内注射顺铂对放射后野肺癌复发的安全性和有效性。该技术的主要优点是它为孤立性、肺门和纵隔肺癌复发患者提供了全身化疗的替代治疗选择。

为了实时可视化瘤内顺铂注射的肺门、纵隔和支气管周围结构,首先对已禁食和口服液体至少 6 小时的患者静脉注射地塞米松和昂丹司琼。接下来,通过静脉注射咪达唑仑和芬太尼治疗诱导清醒镇静,同时局部应用 5 毫升利多卡因。使用标准监测,包括用于心率监测的连续 3 导联心电图、连续脉搏血氧饱和度和呼吸频率测量。

现在,使用凸面探头 EBUS 定位目标病变,并在柔性支气管镜上配备内置超声探头,以将内窥镜推进到声带。当内窥镜到达气道时,打开 EBUS 处理器并使用 1 到 2 毫升生理盐水给内窥镜尖端的球囊充气。将内窥镜弯曲穿过气道壁以定位病变。

然后将 22 号 EBUS 针穿过内窥镜的工作通道并将针锁定到位。在实时超声引导下,穿刺气管支气管壁,将针头插入目标病灶。去除针头内的管心针,将 10 毫升顺铂注射到病灶中。

然后将针头缩回鞘中,将针头注射到病灶的单独区域,再注射 10 毫升顺铂。从内窥镜的工作通道中取出针头,并从远端气道中吸取任何其他药物。然后取下支气管镜。

在这项代表性研究中,治疗后 8 至 12 周,69% 的患者被归类为反应者,31% 被归类为无反应者,中位生存期为 8 个月,反应者为 10 个月,无反应者为 6 个月,在反应者组中观察到的无进展生存率显着更高。在尝试此程序时,选择合适的患者并以系统的方式执行方案中的所有步骤非常重要。开发后,这项技术为我们和肺癌领域的其他研究人员在动物模型和人类中探索瘤内化疗和其他免疫疗法铺平了道路。

看完这个视频,你应该对如何用 EBUS 引导的瘤内顺铂注射治疗肺纵隔和肺门复发有一个很好的了解。
