The last 30 years have shown the increasing role of Ablation in the treatment of malignant liver tumors. By the introduction of percutaneous ethanol injection (PEI) as first ablation tool for percutaneous treatment of hepatocellular carcinoma (HCC) in cirrhosis that firstly showed very high efficacy (1), several ablation techniques (mainly thermal) have been introduced in clinical practice aimed at destroying primary and secondary hepatic tumors as alternative or substitute tools to surgery. Radiofrequency ablation (RFA) was the first thermal technique that showed a good efficacy to ablate liver metastases (2). Among the secondary liver tumors, colorectal liver metastases (CRLM) represent the unique indication for ablation (2). Unlike HCC in cirrhosis where the role of RFA is well defined as first line therapy for HCC nodules < or equal to 2 cm or as alternative to surgery in 1-3 HCC nodules with the maximum diameter<3 cm (3), in the case of CRLM it is not possible to reproduce the same paradigm. Liver resection remains the standard of care for CRLM and the indications to ablation remain confined to nonresectable patients (4). The review article by Takahashi and Berber recently published in HBSN wells illustrates the current role of ablation in treatment of CRLM (5).

背景与目的通过意大利放射治疗和临床肿瘤学学会(Italian Association of Radiotherapy and Clinical Oncology, AIRO)的一项多中心回顾性研究,明确免疫疗法(immunotherapy, IT)和立体定向放疗(stereotactic radiotherapy,SRT)包括放射外科治疗(radiosurgery, RS)或大分割立体定向放疗(hypofractionated stereotactic radiotherapy, HFSRT)治疗非小细胞肺癌(non-small cell lung cancer, NSCLC)脑转移的疗效和毒性。方法对来自19个意大利中心接受SRT+IT的NSCLC伴脑转移患者进行分析,并与单独接受SRT的对照组患者进行比较。结果共纳入SRT+IT组100例和单独SRT组50例。接受SRT+IT的患者有更长的颅内局部无进展生存期(intracranial local progression-free survival, i LPFS)(经倾向性评分调整后,P=0.007)。在诊断为脑转移时接受IT合并有颅外进展的患者中(n=24),接受SRT后再进行IT与较好的总生存期(overall survival, OS)相关(P=0.037)。多因素分析显示组织学类型为非腺癌、卡氏体能状态(Karnofsky performance status,KPS)评分=70分以及接受HFSRT与显著减少的生存期相关(P值分别为0.019、0.017和0.007)。与SRT和IT治疗间隔>7天(n=10)相比,治疗间隔≤7天(n=90)与更长的OS相关(经倾向性评分调整后,P=0.008)。联合治疗耐受性良好。在放射性坏死方面,接受SRT+IT的患者与单独SRT的患者无显著差异。SRT和IT的治疗间隔对毒性发生率无影响。结论 SRT+IT是一种安全的联合治疗方法,与单独SRT相比,具有更长的i LPFS。

This paper presents the results of a first successful attempt to produce hollow micro- and nano-particles of a large variety of materials, dimensions, shapes and hollow attributes by using an environmentally friendly and cheap technology, common in polymer processing and known as gas foaming. The central role played by ad hoc polymeric hollow micro- and nano-particles in a variety of emerging applications such as drug delivery, medical imaging, advanced materials, as well as in fundamental studies in nanotechnology highlights the wide relevance of the proposed method. Our key contribution to overcome the physical lower bound in the micro- and nano-scale gas foaming was to embed, prior to foaming, bulk micro- and nano-particles in a removable and deformable barrier film, whose role is to prevent the loss of the blowing agent, which is otherwise too fast to allow bubble formation. Furthermore, the barrier film allows for non-isotropic deformation of the particle and/or of the hollow, affording non-spherical hollow particles. In comparison with available methods to produce hollow micro- and nano-particles, our method is versatile since it offers independent control over the dimensions, material and shape of the particles, and the number, shape and open/closed features of the hollows. We have gasfoamed polystyrene and poly-(lactic-co-glycolic) acid particles 200 μm to 200 nm in size, spherical, ellipsoidal and discoidal in shape, obtaining open or closed, single or multiple, variable in size hollows.
