早期非小细胞肺癌立体定向消融放疗现状

早期非小细胞肺癌立体定向消融放疗现状

早期非小细胞肺癌立体定向消融放疗现状石安辉;朱广迎【摘要】目前比较立体定向消融放疗(stereotactic ablative radiotherapy, SABR)与手术治疗早期非小细胞肺癌(non-small cell lung cancer, NSCLC)的随机研究证据尚不多,高水平的循证医学证据更是缺乏。

尽管STARS和ROSEL 两项随机研究结果荟萃分析显示SABR较手术耐受性更好,生存不劣于手术,但是目前仍仅推荐拒绝手术或不可手术的早期NSCLC首选SABR,期待着正在进行的随机研究VALOR(Veterans Affairs Lung Cancer Surgery or Stereotactic Ra-diotherapy in the US)和SABRTooth(SABRTooth study in the United Kingdom)的结果。

许多回顾性的研究和病例对照研究显示了SABR治疗的安全性和有效性(局部控制率达90%以上,5年生存率达70%),但是由于肿瘤分期定义、如何决定可否手术及手术患者采用手术方式(开胸或胸腔镜辅助)等不同,很难比较SABR和手术的优劣,尽管大部分结论是两种方法疗效相似,但难以成为循证医学证据,因此争论热点是哪一种方法更安全、创伤更小。

本文将就以上争论热点进行述评。

%High level evidence from randomized studies comparing stereotactic ablative radiotherapy (SABR) to surgery is lacking. Although the results of pooled analysis of two randomized trials for STARS and ROSEL showed that SABR is better tolerated and might lead to better overall survival than surgery for operable clinical stage I non-small cell lung cancer (NSCLC), SABR, however, is only recommended as a preferred treatment option for early stage NSCLC patients who cannot or will not undergo surgery. We, therefore, are waiting for the results of the ongoing randomized studies [Veterans af-fairs lung cancer surgery or stereotacticradiotherapy in the US (VALOR) and the SABRTooth study in the United Kingdom (SABRTooths)]. Many retrospective and case control studies showed that SABR is safe and effective (local control rate higher than 90%, 5 years survival rate reached 70%), but there are considerable variations in the deifnitions and staging of lung cancer, operability determination, and surgical approaches to operable lung cancer (open vs video-assisted). hTerefore, it is diffcult to compare the superiority of radiotherapy and surgery in the treatment of early staged lung cancer. Most studies demonstrated that the effcacy of the two modalities for early staged lung cancer is equivalent;however, due to the limited data, the conclu-sions from those studies are diffcult to be evidence based. hTerefore, the controversies will be focusing on the safety and inva-siveness of the two treatment modalities. hTis article will review the ongoing debate in light of these goals.【期刊名称】《中国肺癌杂志》【年(卷),期】2016(019)006【总页数】5页(P389-393)【关键词】肺叶切除;胸腔镜手术;肺肿瘤【作者】石安辉;朱广迎【作者单位】100142北京,北京大学肿瘤医院暨北京市肿瘤防治研究所放射治疗科;100142北京,北京大学肿瘤医院暨北京市肿瘤防治研究所放射治疗科【正文语种】中文肺癌仍是全球癌症死亡的首要原因,每年超过180万人被诊断为肺癌[1]。

方法回顾性分析2011年7月—2016年7月间156例经手术病理证实为肺腺癌且存在pGGN的病人资料,其中男65例,女91例,年龄37~81岁(中位年龄56岁)。

经手术病理证实,非侵袭性腺癌60例(包括非典型腺瘤样增生28例,原位癌32例),侵袭性腺癌96例(包括微浸润腺癌53例,浸润性腺癌43例)。

应用图像分析软件ImageJ1.50b提取4大类共68个影像组学特征,采用线性回归对所有影像组学特征进行共线性诊断,将不存在共线性的影像组学特征(54个)作为独立参数来预测pGGN的病理侵袭性。

采用二元logistic回归分析建立影像组学特征与pGGN病理类型之间的预测模型,采用向后步进方法选取最佳定量特征,当定量特征P<0.05时纳入模型,当定量特征P>0.10时剔除模型。

采用受试者操作特征(ROC)曲线对模型进行分析,并评价影像组学特征预测pGGN病理侵袭性的效能。

结果二元logistic回归模型从54个影像组学特征中筛选出8个具有统计学意义的影像组学特征(P<0.05),其中描述肿瘤大小的特征2个(面积和周长),描述肿瘤形态的特征2个(椭圆长轴和椭圆短轴),描述肿瘤灰度直方图的特征3个(众数、最大灰度值和直方图峰度),描述肿瘤纹理的特征1个(灰度共生矩阵熵值)。

皮肤影像学检查在常见非黑素皮肤癌手术中的应用进展

皮肤影像学检查在常见非黑素皮肤癌手术中的应用进展

皮肤影像学检查在常见非黑素皮肤癌手术中的应用进展作者:战胜霞万学峰来源:《中国美容医学》2022年第08期[摘要]目前常见非黑素皮肤癌(Non-melanotic skin cancer,NMSC)的首选治疗是手术切除,精准确定肿瘤边界对于彻底切除肿瘤、最大限度保留皮肤功能及美容至关重要。

随着对NMSC术前边界无创检测方法研究的逐渐深入,皮肤高频超声(High frequency ultrasound,HFUS)、皮肤镜、皮肤CT和光学相干断层扫描成像技术(Optical coherence tomography,OCT)在一定程度上可以为术者评估手术切缘提供依据。

但上述无创检测方法各有其优缺点,临床上可通过联合应用实现手术精准治疗,取得更好的疗效。

本文就国内外皮肤影像学检查在确定肿瘤边界方面的研究进展综述如下。

中文题目为什麼低次放疗和放射外科能有效治疗良性和恶(精)

中文題目:為什麼低次放療和放射外科能有效治療良性和惡性疾病英文題目:Why Hypofractionated Radiotherapy and Radiosurgery Can Effectively Treat Benign and Malignant Diseases陳光耀Kuang Y. Chen, M.D., Ph.D.臺北榮民總醫院癌病中心For nearly one hundred years, 2 Gy per day is the norm of fractionation in radiotherapy for human epithelial cancers, the whole course of treatment generally last 6 to 8 weeks with 30-40 fractions. Because of normal tissue reactions, attempt to shorten the treatment course by increasing the daily dose or daily number of fraction is very difficult to achieve. On the other extreme, Lars Leksell, a neurosurgeon of Sweden, used one fraction of large dose of gamma rays to treat the intracranial lesion successfully in 1967 opened a new discipline of medicine called Gamma Knife radiosurgery. For the past forty years, hundred of Gamma Knives have been practicing in medical centers and hospitals where no less than 350,000 patients had been treated for their intracranial benign and malignant lesions. The radiosurgical equipment extends from Gamma Knife to X Knife to nowaday, CyberKnife. In the matter of fact, hypofractionated radiotherapy appears in brachytherapy, teleradiotherapy with oral, vaginal and rectal cones, intraoperative radiotherapy, proton and heavy ion treatment. Why conventional radiotherapy needs 35 fractions of 2 Gy and radiosurgery can deliver 25-60 Gy in one to five fractions to treat biologically similar epithelial tumors? For trigeminal neuralgia, radiosurgeons even give 70-80 Gy in one fraction and the treatment is still safe and effective. The answer of this mark difference in fraction size and number are targeting accuracy and diversification of incoming treatment beams. Any attempt to adopt the radiosurgical principles to treat extracranial lesions without adequate patient fixation, reliably tackle the target movement becomes an extremely risky practice.Take malignant tumor as an example, target movement can be day to day, hour to hour, minute to minute and second to second. Examples of day to day target movement are patient setup errors, urinary bladder and rectal filling and tumor pushing, tumor shrinkage, weight loss and skin motion etc. Hour to hour and minute to minute target movements are bladder and rectal filling and tumor pushing, positionchanges due to unnoticed muscle flexion and relaxation. Second to Second target movements are tumor moves along with respiration, heartbeat, peristalsis, cough and sudden pain etc. IGRT (image-guided radiotherapy) at its best is only partially responded to day to day target movement. There seems no radiotherapeutic system response to intrafractional target movement satisfactory except CyberKnife.With its submillimeter targeting accuracy for stationary tumor treatment and 1.5 mm accuracy of dynamic treatment for tumors move along with respiration under natural breathing, CyberKnife is able to treat lesions of different parts in the body by 1-5 fractions, on the average 2-3 fractions in many hospitals. This is a truly hypofractionated radiotherapy, even though many people call it radiosurgery. The CyberKnife technique to overcome the target movement is a pairs of ceiling mounted X-ray tubes which 45°diagonally expose the target for patient setup and intrafractional target movement detection, any 6D translational and rotational movement can be real-time automatically detected and corrected either by automatic readjustment of the 6D couch position or by automatically moving the 6 MV X-ray source to a new position and angulation as to compensate any deviation from digitally reconstructed radiograph derived from treatment planning CT images. Synchrony is the system that the CyberKnife uses to setup 4D irradiation for thoracic and abdominal tumors moving along with respiration. The principle of Synchrony is relatively simple. Under natural respiration, one set of three cameras receive the red-light moving signals which emitted from the chest wall as the external movement track, another set of multiple X-ray exposures at different time points of a respiratory cycle of the tumor or golden markers around the tumor construct the internal target movement, couple the external and internal movement information into a mathematical model, the robotic arm as well as the X-ray treatment beams can follow the respiratory rhythm to do the 4D dynamic irradiation.There are good reasons in physics and biology that hypofractionated radiotherapy can effectively treat variety of benign and malignant diseases, at least in the CyberKnife system, namely: diversification of treatment beams, accuracy of beam delivery and overcome target movement physically; newly concept of cell survival models, therapeutic ratio gain and other rationales of hypofractionation radiobiologically. Therefore philosophically, hypofractionation is a hundred years old technique in medical history of radiotherapy and radiosurgery, the safety and efficacy are ever better in the well-designed equipment such as CyberKnife, the indication oftreatment are becoming wider, the therapeutic course is much shorter and simpler,only waiting for clinicians to accept.In summary, using its 150 Kg linear accelerator and robotic arm, as well as in-room X-ray imaging equipment and Synchrony system to track the real-time position of the target and then to tackle the inter- and intrafractional target movement, CyberKnife is able to deliver variable diameter (5-60mm) 6 MV X-ray beams accurately from 1,500 solid angles toward the target, the dose distribution is highly conformal and homogenous, the rapid fall off of the marginal dose around the tumor render the surround normal tissue well protected. Only under these circumstances the CyberKnife is able to treat variety of benign and malignant lesions in the hypofractionated schemes as presented during the meeting and in the newly published monograph named ”CyberKnife Radiosurgery Treatment Guidelines” in Chinese by the same author of this paper. If more cases and longer follow-up repeatedly indicated that CyberKnife stereotactic radiosurgery is more effective and safer than conventional fractionated radiotherapy and radiosurgery, I assume that CyberKnife hypofractionation is the future of radiotherapy and radiosurgery, and may be the future of certain parts of surgical oncology!。

EDGE radiosurgery: non-invasive cancer treatment
EDGE Radiosurgery system developed by Varian company has received FDA 510(k) clearance on January 23rd, 2013. EDGE is the most effective and non-invasive approach to treat cancer. EDGE has an advanced real-time motion management system, including the Calypso® GPS for the Body® system (approved by FDA on July 21st, 2014) and an optical surface monitoring system for real-time tracking tumor motion during treatment every 10 milliseconds. In addition, EDGE has been equipped with the advanced Motion & Image-Guided Radiotherapy (IGRT) package, which encompasses two-, three-, and four dimensional imaging. Integrated these unparalleled techniques, EDGE has a high- intensity and high-definition 2.5mm multi-leaf collimator with fast dose delivery up to 2400 MU/min and provides a distinct cancer radiosurgery with sub-millimeter accuracy.
First installation of EDGE radiosurgery suite in the world was homed in Henry Ford Health System (HFHS) in September 2013, and officially run in March 2014. EDGE performs noninvasive cancer procedures anywhere in the body - especially in the brain, spine, head and neck, lung, live –with extreme precision. For patients in China to HFHS for EDGE treatment, Beijing Henry Ford Health Consulting Company (HFHC) was established a s a liaison and provides comprehensive arrangements.
Some features of the new system:
●The PerfectPitch™ couch:An integrated six degrees of freedom (6DoF) treatment couch
that provides the accuracy, precision, and flexibility needed to position patients optimally, adjust their position to correct for any misalignments, and support them comfortably during treatment. The PerfectPitch couch has been designed for the accuracy and functionality required to deliver radiosurgery treatments in the brain and in the rest of the body.
●The Advanced Motion & Image-Guided Radiotherapy (IGRT) package: An advanced
motion management package that offers clinicians many options for using real-time imaging during radiotherapy treatments. It also enables expanded use of fluoroscopy and 4-D cone-beam CT—imaging techniques that show motion over time—to better compensate for tumor motion during treatment.
●Intracranial radiosurgery package: An integrated set of technologies for planning and
delivering stereotactic radiosurgery treatments for tumors or functional abnormalities in the brain. The intracranial radiosurgery package supports the accurate delivery of radiation using multiple beam shaping options, including Varian’s high-definition multileaf collimator and radiosurgery conical collimators, and is compatible with both frame-based and frameless patient immobilization approaches.
●Calypso system: Several enhancements have been incorporated into the Calypso system for
real time tracking. The system utilizes transponders, or position signaling devices, that are implanted in or around a tumor, or placed on the surface of the body and monitored to track motion during treatment. New enhancements increase the rate of transponder signal processing in order to track faster types of motion, such as respiratory motion, in real time.
The system is also compatible with the couch rotations that are often used to optimize targeting during treatments in the lung. The new system also includes updated usability features designed to streamline treatments and enhance the user experience.。
