Impact of pathological response after preoperative transcatheter arterial chemoembolization (TACE) on incidences of microvascular invasion and early tumor recurrence in hepatocellular carcinoma: a multicenter propensity score matching analysis

BackgroundTo study the influence of pathological responses (PR) after transcatheter arterial chemoembolization (TACE) on incidences of microvascular invasion (MVI) and early recurrence in hepatocellular carcinoma (HCC) patients.MethodsBetween 2013 to 2015, consecutive HCC patients who underwent liver resection with “curative” intent at three hospitals were enrolled in this study. Patients with different areas of PR after preoperative TACE were compared with those without preoperative TACE on the incidences of MVI, early recurrence rates and patterns of recurrence before and after propensity score matching (PSM).ResultsOf 1,970 patients, 737 patients who received preoperative TACE were divided into three groups according to the areas of PR: ≥90% (n=226), 60–90% (n=447), and <60% (n=64). PR ≥90% was an independent protective factor of incidences of MVI [odds ratio (OR), 0.144; 95% confidence interval (CI), 0.082–0.245, P<0.001) and early recurrence (HR, 0.742; 95% CI, 0.561–0.963, P=0.032); while PR<60% was an independent risk factor of incidences of MVI (OR, 6.076; 95% CI, 3.004–11.728, P<0.001) and early recurrence (HR, 1.428; 95% CI, 1.095–1.929; P=0.009). Furthermore, patients with PR <60% were significantly more likely to develop multiple intrahepatic recurrences involving multiple hepatic segments when compared with patients without preoperative TACE.ConclusionsThis study indicated the area of PR after TACE was closely associated with the incidences of MVI and early tumor recurrence. Patients with PR <60% were at significantly higher risks of having more MVI, early and multiple tumor recurrences     

Bone metastases in non-small cell lung cancer: a narrative review

Background and ObjectiveBone metastases are common in patients with non-small cell lung cancer (NSCLC) and remain a significant source of morbidity, mortality, and diminished quality of life, despite the considerable progress made in the overall management of patients with metastatic NSCLC over the last decade. Understanding the molecular pathogenesis of bone metastases is critical to improving survival, preserving function, and managing symptoms in this patient population. The objective of our review is to provide a comprehensive review of the pathophysiology, clinical presentation, management, and factors predicting the development and prognosis of patients with NSCLC with bone metastases.MethodsAn online electronic search was performed on PubMed and Google Scholar of all English-language literature using combinations of the following keywords: bone metastases, non-small cell lung cancer, pathophysiology, skeletal related events, response to therapy, predictive factors, and immunotherapy. Bibliographies of identified papers were reviewed for additional articles of interest. Observational cohort, retrospective studies, randomized controlled trials (RCTs), meta-analyses, and review articles were examined for this review.Key Content and FindingsBone metastases in lung cancer patients remain a common occurrence, impacting morbidity, mortality, and quality of life. Patients with skeletal related events (SREs) have worse prognosis. There is data supporting use of bisphosphonates and/or denosumab, and these should be considered in all patients with bone metastases. Novel studies comparing the genomic alterations of skeletal metastases and primary tumors are needed. As therapy for patients with advanced disease evolves, more studies are needed to evaluate the interplay between immunotherapy and bone metastases, and in determining the response to treatment in bone.ConclusionsPredicting development and progression of bone metastases could allow earlier and targeted therapy in patients with bone metastases. Predicting and evaluating response to conventional chemotherapy and immune checkpoint inhibitors in NSCLC patients with bone metastases remains an unmet need and merits further study.

急性受热及热适应对机体免疫系统的影响

雄性ＳＤ大鼠随机分为５组：２５℃对照组，３７℃每天２ｈ共７天热适应组，４２℃分别受热３０ｍｉｎ、６０ｍｉｎ，９０ｍｉｎ的３个热处理组。检测全血淋巴细胞转化率、α－醋酸萘酯酶活性、腹腔巨噬细胞活性和吞噬功能。结果显示：７天热适应组与受热３０ｍｉｎ组即明显降低，随受热时间延长（超过３０ｍｉｎ），巨噬细胞吞噬功能显著降低，不能形成吞噬峰。７天热适应组与受热３０ｍｉｎ组用ＰＨＡ刺激全血淋巴细胞转化的刺激指数比对照组稍高，但差异不明显（Ｐ＞０．０５），而６０ｍｉｎ和９０ｍｉｎ受热却使该指数显著下降（Ｐ分别为０．００３１和０．００６３）。α－醋酸萘酯酶除热适应组降低外，其余各组无明显变化。结果提示，急性受热时机体免疫系统功能有受抑制倾向。

目的研究多频听觉稳态反应(ASSR)和短纯音听觉脑干诱发电位反应阈(Tb-ABR)与纯音测听(PTA)阈值的差别和相关性。方法选择正常听力耳50例(正常听力组)和听力障碍耳36例(又分为轻、中、重度听力障碍组),分别进行ASSR、Tb-ABR和PTA测听检查,比较两组的ASSR、Tb-ABR反应阈及PTA阈值,同时就ASSR、Tb-ABR反应阈与PTA阈值进行相关性分析。结果ASSR和Tb-ABR反应阈与PTA阈值均有良好的相关性。在听力障碍组中,Tb-ABR的反应阈与PTA阈值接近,而ASSR反应阈与PTA阈值间差值较大。ASSR反应阈与PTA阈值间的相关性要普遍优于Tb-ABR反应阈与PTA阈值间的相关性。结论ASSR和Tb-ABR均为较好的评估行为听阈的客观测听方法。
