Outcomes after neoadjuvant or adjuvant chemotherapy for cT2-4N0-1 non–small cell lung cancer: A propensity-matched analysis

Objective

Comparative survival between neoadjuvant chemotherapy and adjuvant chemotherapy for patients with cT2-4N0-1M0 non–small cell lung cancer has not been extensively studied.

Pre- or postoperative radiotherapy for soft tissue sarcomas

Sarcomas are rare tumours arising from mesenchymal tissue. A multimodal management in an expert centre combining surgery and radiotherapy is the current standard of care for localized soft-tissue sarcomas of the extremities, to enable limb-sparing strategies. The delivery of pre- radiotherapy or postoperative radiotherapy offers similar local control and survival rates but the toxicity profile is quite different: preoperative radiotherapy increases the risk of wound complications and postoperative radiotherapy affects long-term functional outcomes. While postoperative radiotherapy has long been the rule, especially in Europe, technical improvements with image-guided- and intensity-modulated radiotherapy associated with a better management of postoperative wounds has tended to change practices with more frequent preoperative radiotherapy. More recently the possibilities of a hypofractionated regimen or potentiation by nanoparticles to increase the therapeutic index plead in favour of a preoperative delivery of radiotherapy. The aim of this paper is to report pros and cons of pre- and post-operative radiotherapy for soft-tissue sarcomas.     

Stereotactic body radiotherapy for Stage I lung cancer with chronic obstructive pulmonary disease: special reference to survival and radiation-induced pneumonitis

This retrospective study aimed to evaluate radiation-induced pneumonitis (RIP) and a related condition that we define in this report—prolonged minimal RIP (pmRIP)—after stereotactic body radiotherapy (SBRT) for Stage I primary lung cancer in patients with chronic obstructive pulmonary disease (COPD). We assessed 136 Stage I lung cancer patients with COPD who underwent SBRT. Airflow limitation on spirometry was classified into four Global Initiative for Chronic Obstructive Lung Disease (GOLD) grades, with minor modifications: GOLD 1 (mild), GOLD 2 (moderate), GOLD 3 (severe) and GOLD 4 (very severe). On this basis, we defined two subgroups: COPD-free (COPD −) and COPD-positive (COPD +). There was no significant difference in overall survival or cause-specific–survival between these groups. Of the 136 patients, 44 (32%) had pmRIP. Multivariate analysis showed that COPD and the Brinkman index were statistically significant risk factors for the development of pmRIP. COPD and the Brinkman index were predictive factors for pmRIP, although our findings also indicate that SBRT can be tolerated in early lung cancer patients with COPD.     

坐骨重叠征与发育性髋关节脱位手术后再脱位的相关性分析

目的提出坐骨重叠征(ischium overlap sign,IOS)的概念,并分析其与发育性髋关节脱位(developmental dysplasia of the hip,DDH)手术后再脱位的关系。方法回顾性分析2013年9月至2017年5月山东大学附属省立医院治疗的88例(105髋)DDH患儿病例资料,其中男童16例、女童72例;平均年龄12(5~24)个月,平均随访时间34(15~59)个月;双侧17例,左侧63髋,右侧42髋;1髋为髋臼发育不良,11髋半脱位,93髋全脱位。术中行髋关节造影检查,按照Bowen标准选择闭合或切开复位石膏固定术。IOS是指在人类位髋关节造影平片上股骨头软骨内缘与坐骨外缘的重叠关系,二者重叠为Ⅰ度,相接为Ⅱ度,分离为Ⅲ度。将93髋全脱位按照IOS分度进行分组,比较组间再脱位发生率。结果 1髋髋臼发育不良和11髋半脱位者IOS均为Ⅰ度。93髋全脱位中IOSⅠ度14髋,Ⅱ度39髋,此两组均行闭合复位石膏固定,无再脱位病例;Ⅲ度40髋中,闭合复位石膏固定17髋,6髋再脱位;切开复位石膏固定23髋,1髋再脱位。本研究发现Ⅲ度组的再脱位发生率(7/40,17.5%)高于其他两组(P=0.006)。IOS为Ⅲ度的40髋中,闭合复位的再脱位发生率(6/17,35.3%)高于切开复位(1/23,4.4%),差异有统计学意义(X^2=4.518,P=0.034)。结论 IOS与DDH术后再脱位有一定的关系,IOS为Ⅲ度的髋关节如行闭合复位,再脱位的风险较高。     

Chest wall pain following lung stereotactic body radiation therapy using 48 Gy in three fractions: A search for predictors

Purpose

Chest wall pain is an uncommon but bothersome late complication following lung stereotactic body radiation therapy. Despite numerous studies investigating predictors of chest wall pain, no clear consensus has been established for a chest wall constraint. The aim of our study was to investigate factors related to chest wall pain in a homogeneous group of patients treated at our institution.

护理干预对放疗科头颈部肿瘤放疗患者生活质量的影响

目的本文主要研究和探讨护理干预对放疗科头颈部肿瘤放疗患者生活质量的影响。方法将我院2017年2月份至2018年10月份收治的100例头颈部肿瘤放疗患者作为本次研究的对象,在随机原则的指导下把100例患者分为对照组和实验组,每组患者的数量为50例。对照组患者给予常规护理,实验组患者实施护理干预,对两组患者的生活质量、睡眠质量、护理满意度和护理依从性等进行对比分析。结果在生活质量、睡眠质量、护理满意度和护理依从性等方面,组间进行对比分析,实验组都明显优于对照组,P<0.05差异具有统计学意义。结论对头颈部肿瘤放疗患者实施护理干预可以让患者的生活质量、睡眠质量、护理依从性以及护理满意度等都得到显著的改善,从而让患者以一种积极、乐观的心态接受放疗,这对于放疗效果的提高具有重要的作用。总之,这一护理模式应该在临床中进行推广和使用。     

放疗在肝癌治疗中应用的研究进展

肝癌是临床上常见的恶性肿瘤，因早期症状不典型，至发现时往往已为中晚期，失去最佳手术治疗时机和机会。作为非手术治疗之一的放射治疗技术，其发展在近年来已有了较大的进步。放疗包括体外放疗和体内放疗，皆具有一定的治疗效果和相对可控的不良反应。本文就肝癌放射治疗的应用进展作一综述。     

Postoperative development of sarcopenia is a strong predictor of a poor prognosis in patients with adenocarcinoma of the esophagogastric junction and upper gastric cancer

Background

There were few studies assessed the postoperative sarcopenia in patients with cancers. The objective of present study was to assess whether postoperative development of sarcopenia could predict a poor prognosis in patients with adenocarcinoma of esophagogastric junction, (AEG) and upper gastric cancer (UGC).

Major hepatectomy for intrahepatic cholangiocarcinoma or colorectal liver metastases. Are we talking about the same story?

IntroductionMajor hepatectomy (MH) is often needed in the curative management of intrahepatic cholangiocarcinoma (IHCC) and colorectal liver metastases (CRLM). While similar outcomes could be expected after MH for IHCC and CRLM, outcomes seem worse after MH for IHCC. A better understanding of such differences might help improving perioperative outcomes but comprehensive analysis are lacking.MethodsAll patients undergoing curative intent MH for IHCC or CRLM from 2003 to 2009 were included from two dedicated multi-institutional datasets. Preoperative management and short-term outcomes after MH were first compared. Independent predictors of postoperative mortality and morbidity were identified.ResultsAmong 827 patients, 333 and 494 patients underwent MH for IHCC and CRLM, respectively. Preoperative portal vein embolization was more frequently performed in the CRLM group (p < 0.001). MH in the IHCC group required more extended resection (p < 0.001). Postoperative mortality and severe morbidity rates were significantly higher in the IHCC group (7.2% vs. 1.2% and 29.7% vs. 11.1%, p < 0.001, respectively). Main causes for mortality were postoperative liver failure and deep surgical site infection. MH for IHCC was an independent risk factor for mortality (p < 0.001) and severe morbidity (p < 0.001). After propensity score matching (212 patients in each group), the aforementioned differences regarding outcomes remained statistically significant.ConclusionThis study suggests that IHCC patients are inherently more at risk after MH as compared to CRLM patients. Considering that postoperative liver failure was the most frequent cause of death, preoperative planning might have been inadequate in the setting of IHCC while more complex/extended resections should be expected.
