Prognostic significance of number versus location of positive mesenteric nodes in stage iii colon cancer

IntroductionDebate persists on the ideal extent of lymphadenectomy for colon cancer (CC). Specifically, it is unknown whether the anatomical location of positive lymph nodes (LN) has any independent prognostic significance. We assessed the prognostic value of positive LN location in stage III CC patients who underwent extensive (D3) lymphadenectomy.MethodsPatients from Kanagawa Cancer Center, Japan, who underwent D3 dissection for CC from 2000 to 16 were analyzed. Mesenteric LN were classified according to location as paracolic (L1), intermediate (L2), or central (L3). Recurrence-free survival (RFS) and the corresponding hazard function were evaluated with their trends over the L groups. Multivariate Cox models were used to evaluate the association of LN location with RFS.ResultsFour hundred forty-six stage III patients were analyzed. The mean number of examined/positive nodes per patient was 42.5/2.6 in L1 (n = 310), 40.9/4.8 in L2 (n = 111), and 44.0/9.8 in L3 (n = 25). RFS was worse for L3 vs. L2 (HR: 2.00, 95%CI [1.05–3.75], p = 0.034) and for L3 vs. L1 (2.62 [1.45–4.71], p = 0.001), but not significantly different between L2 and L1 (1.32 [0.89–1.5], p = 0.17). In a multivariate model adjusting for age, tumor size, and number of lymph nodes harvested T-stage (p < 0.001), adjuvant therapy (p < 0.0038), lymphatic invasion (p = 0.023), and LNR (p = 0.038) were significantly associated with RFS, but not L level or tumor location.ConclusionThe anatomical location of invaded LN does not significantly correlate with RFS in CC, after adjusting for potential confounders. Central LN are infrequently invaded and confer a worse RFS.

目的 分析2014—2018年天津市肿瘤医院门诊麻醉性镇痛药的使用情况，为临床合理使用提供参考。方法 调取天津市肿瘤医院2014—2018年门诊麻醉性镇痛药的用药相关信息，对药物剂型、使用金额、用药频度（DDDs）、日均费用（DDC）及药品排序比（B/A）进行统计分析。结果 2014—2018年门诊麻醉性镇痛药中，口服剂型的使用金额和DDDs的构成比逐年上涨，透皮贴剂和注射剂使用金额和DDDs的构成比呈下降趋势。硫酸吗啡缓释片30 mg的DDDs排名一直居于首位，羟考酮缓释片10 mg在2016年后上升至第2位，羟考酮缓释片40 mg排名大幅上升，芬太尼透皮贴剂8.4 mg的DDDs排名出现明显下降。2016—2017年各麻醉性镇痛药的DDC开始略有下降。各药品的B/A略有变化，均接近1，表明使用金额与使用频度的同步性较好。结论 天津市肿瘤医院麻醉性镇痛药的使用合理，符合安全、有效、方便的原则。     

左奥硝唑治疗厌氧菌感染的系统评价

摘 要 目的：系统评价左奥硝唑治疗厌氧菌感染的临床疗效及安全性，为临床合理用药提供参考。方法：计算机检索PubMed、Medline（viaOvidSP）、Cochrane Library、CNKI、WanFang Data、VIP数据库，搜集有关左奥硝唑治疗厌氧菌感染的随机对照试验（RCTs），检索时限均为建库至2018年10月1日，由两名研究人员独立交叉筛选文献，并进行质量评估和数据提取，采用RevMan 5.3软件进行Meta分析。结果：纳入16个RCTs，共计1 557例研究对象，其中左奥硝唑治疗厌氧菌感染的试验组779例，奥硝唑治疗厌氧菌感染的对照组778例。Meta分析结果显示：试验组的临床治愈率明显优于对照组，差异有统计学意义[OR=2.28，95%CI（1.60，3.25），P<0.000 01]；但腹部感染两组临床治愈率差异无统计学意义[OR=1.73，95%CI（0.76，3.96），P<0.19]。两组在细菌清除上效果相当，差异无统计学意义（P＞0.05）。试验组在消化系统不良反应、过敏反应以及白细胞减少等方面的发生率略低于对照组，但差异均无统计学意义（P＞0.05）；但在神经系统不良反应方面，试验组与对照组相比发生率较低，差异有统计学意义（P＜0.05）。在假设其他治疗方案一致的情况下，试验组的成本及成本 效果比显著高于对照组，在一定程度上增加了患者的医疗负担。结论：基于目前的临床研究，左奥硝唑治疗厌氧菌感染可提高临床治愈率，减少神经系统不良反应的发生，但鉴于临床发生的药品不良反应均为轻中度，无需针对治疗处理，停药后即可缓解或消失，且奥硝唑的成本 效果比远低于左奥硝唑，因此，临床医生综合评估患者病情后仍可考虑选用奥硝唑治疗厌氧菌感染。而对于合并消化系统、神经系统、免疫系统、恶性肿瘤等基础疾病，以及药品不良反应不耐受的患者，则可优选左奥硝唑。     

Colitis following the use of immune checkpoint inhibitors: A real-world analysis of spontaneous reports submitted to the FDA adverse event reporting system

BackgroundAlthough colitis has been reported in patients treated with immune checkpoint inhibitors (ICIs), associations between colitis and ICIs had not been thoroughly assessed in real-world studies. Here, we identified and characterized significant colitis-associated with ICIs.MethodsBased on the Food and Drug Administration Adverse Event Reporting System (FAERS) from January 2004 to December 2019, the disproportionality analysis and Bayesian analysis, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN) and the multi-item gamma Poisson shrinker (MGPS) algorithms were adopted to data mining of the suspected adverse events of colitis after ICIs administrating. Clinical characteristics of patients with ICIs-associated colitis and the time to onset of colitis following different ICI regimens were collected.ResultsA total of 3786 reports of colitis adverse events were identified with ICIs. Seven ICI monotherapies were associated with the reporting of colitis. Statistically significant ROR, PRR, information component (IC), and empirical Bayesian geometric mean (EBGM) emerged for all ICI monotherapies and combination therapies. ICIs-associated colitis affected mostly male (53.51%), with a wide mean age range (60.65 to 72 years). Colitis adverse events were commonly reported in patients with melanoma and lung cancer. Adverse outcomes of colitis concerning ICI were mainly outcomes of hospitalization-initiated or prolonged and other serious. Among colitis cases, 17.43% cases of colitis concerning ICI lead to death. The adverse event of colitis occurred earliest in ipilimumab monotherapy with a median time to onset of 64.21 days (IQR: 27–69 days) among all monotherapies.ConclusionsICI may lead to severe and disabling ICIs-associated colitis during therapy. Analysis of FAERS data identified signals for adverse events of colitis with ICI regimens. Practitioners should consider the factors that may increase the likelihood of colitis. The findings support a continued surveillance and risk factor identification studies.     

Can the unnecessary operations for suspected thyroid nodules be avoided by the combined use of the strain ratio and elastography score?

IntroductionOnly 5%–15% of thyroid surgical specimens are reported as malignant. Most of the operations are performed due to suspicion of malignancy as a result of fine needle aspiration biopsy but invasiveness, non-diagnostic results and potential repeat biopsies are disadvantages of fine needle aspiration biopsy.ObjectiveThe aim of this study was to investigate the effectiveness of simultaneously using both the strain ratio and elasticity score in the differential diagnosis of thyroid nodules, as well as to assess the compatibility of these two methods.MethodsA total of 144 nodules were included in the study. The final histopathologic diagnosis was used as the reference standard. The area under the curve sensitivity, specificity, and cut-off values of the strain ratio and elasticity score were determined using receiver operating characteristic curve analysis. The compatibility and comparison of strain ratio and elasticity score were also performed.ResultsTwenty eight nodules (19.4%) were malignant. The strain ratio and elasticity score results were found to be significantly successful in predicting thyroid malignancy (p < 0.001 for both). Moreover, the area under the curve for the strain ratio and elasticity score were found to be 0.944 and 0.960, respectively. The diagnostic accuracy of the elasticity score was found to be superior to that of the strain ratio, but this difference was not statistically significant (p = 0.456). When the compatibility of the strain ratio and elasticity score was examined, the two evaluations were revealed to be statistically consistent with each other (Kappa = 0.767; p < 0.001). When the strain ratio and the elasticity score were used together, the specificity of capturing the correct diagnosis increased from 84.5% to 93.1%.ConclusionWhen the strain ratio an elasticity score were used together for the differential diagnosis of thyroid nodules, more accurate results were obtained. Thus, combining both methods may be a promising alternative to fine needle aspiration biopsy in order to prevent unnecessary surgical interventions for suspected thyroid nodules.
