1Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
2Update on surgical treatment of pancreatic neuroendocrine neoplasms显示文摘Pancreatic neuroendocrine neoplasms(PNENs) are rare and account for only 2%-4% of all pancreatic neoplasms. All PNENs are potential(neurendocrine tumors PNETs) or overt(neuroendocrine carcinomas PNECs) malignant,but a subset of PNETs is low-risk. Even in case of low-risk PNETs surgical resection is frequently required to treat hormone-related symptoms and to obtain an appropriate pathological diagnosis. Low-risk PNETs in the body and the tail are ideal for minimallyinvasive approaches which should be tailored to the individual patient. Generally,surgeons must aim for parenchyma sparing in these cases. In high-risk and malignant PNENs,indications for tumor resection are much wider than for pancreatic adenocarcinoma,in many cases due to the relatively benign tumor biology. Thus,patients with locally advanced and metastatic PNETs may benefit from extensive resection. In experienced hands,even multi-organ resections are accomplished with acceptable perioperative morbidity and mortality rates and are associated with excellent long term survival. However,poorly differentiated neoplasms with high proliferation rates are associated with a dismal prognosis and may frequently only be treated with chemotherapy. The evidence on surgical treatment of PNENs stems from reviews of mostly singlecenter series and some analyses of nation-wide tumor registries. No randomized trial has been performed to compare surgical and non-surgical therapies in potentially resectable PNEN. Though such a trial would principally be desirable,ethical considerations and the heterogeneity of PNENs preclude realization of such a study. In the current review,we summarize recent advances in the surgical treatment of PNENs.Jan G D’Haese Chiara Tosolini Güralp O Ceyhan Bo Kong Irene Esposito Christoph W Michalski J?rg Kleeff 2014World Journal of Gastroenterology2014,20,38:4
3一种房颤风险评分系统的建立(Framingham心脏研究):基于社区的队列研究显示文摘背景房颤导致了发病率和病死率的显著上升。本研究旨在建立一种预测个体罹患房颤绝对风险的风险评分系统,并提供研究人员评价新危险因素的流程。方法作者评估了Framingham心脏研究中于1968年6月至1987年9月间进行了8044次检测的4764例参与者(55%为女性,年龄45~95岁)。此后,参与者被随访至房颤首发,随访期最长达10年。多变量Coxi回归确认出1(1年内罹患房颤的临床危险因素。次级分析纳入了常规超声心动图检测指标(5152例4参与者,7156次检测)对房颤风险进行再分层评估,并评价超声检测指标能否提高风险预测能力。结果4764例参与者中的457例4(10%)罹患房颤。年龄、性别、体重指数、收缩压、降压治疗、PR间期、有临床意义的心脏杂音及心力衰竭与房颤相关,并被纳入了风险评分模型(除体重指数P=0.08外,其余均为P〈0.05),模型的C统计量为0.78(95%CI0.76~0.80)。10年房颤风险随年龄变化:年龄〈65岁的人群中53例(1%)风险高于15%,而〉65岁的人群中为783例(27%)。为提高预测能力而纳入超声检测指标仅使模型C统计量略微增高,由0.78(95%C10.75~0.80)增至0.79(95%CI0.77~0.82:P=0.005)。超声心动图检测指标并不能改善风险再分层评估(P=0.18)。结论基于社区医疗中易得的临床因素建立的风险评分系统,有助于确认社区个体罹患房颤的风险,评估技术或标志物能否改善风险预测,以及针对高危个体采取预防措施。Renate B Schnabel Lisa M Sullivan Daniel Levy Michael J Pencina Joseph M Massaro Ralph B D'Agostino Sr Christopher Newton-Cheh Jennifer F Yamamoto Jared W Magnani Thomas M Tadros William B Kannel Thomas J Wang Patrick T Ellinor Philip A Wolf Ramachanclran S Vasan Emelia J Benjamin 黄刚(译) 2009世界临床医学2009,,9:2

16Renal impairment and heart failure with preserved ejection fraction early post-myocardial infarction显示文摘AIM:To study if impaired renal function is associated with increased risk of peri-infarct heart failure (HF) in patients with preserved ejection fraction (EF).METHODS:Patients with occluded infarct-related arteries (IRAs) between 1 to 28 d after myocardial infarction (MI) were grouped into chronic kidney disease (CKD) stages based on estimated glomerular filtration rate (eGFR).Rates of early post-MI HF were compared among eGFR groups.Logistic regression was used to explore independent predictors of HF.RESULTS:Reduced eGFR was present in 71.1% of 2160 patients,with significant renal impairment (eGFR < 60 mL/min every 1.73 m2) in 14.8%.The prevalence of HF was higher with worsening renal function:15.5%,17.8% and 29.4% in patients with CKD stages 1,2 and 3 or 4,respectively (P < 0.0001),despite a small absolute difference in mean EF across eGFR groups:48.2 ± 10.0,47.9 ± 11.3 and 46.2 ± 12.1,respectively (P=0.02).The prevalence of HF was again higher with worsening renal function among patients with preserved EF:10.1%,13.6% and 23.6% (P < 0.0001),but this relationship was not significant among patients with depressed EF:27.1%,26.2% and 37.9% (P= 0.071).Moreover,eGFR was an independent correlate of HF in patients with preserved EF (P=0.003) but not in patients with depressed EF (P=0.181).CONCLUSION:A significant proportion of post-MI patients with occluded IRAs have impaired renal function.Impaired renal function was associated with an increased rate of early post-MI HF,the association being strongest in patients with preserved EF.These findings have implications for management of peri-infarct HF.Vinod Jorapur Gervasio A Lamas Zygmunt P Sadowski Harmony R Reynolds Antonio C Carvalho Christopher E Buller James M Rankin Jean Renkin Philippe Gabriel Steg Harvey D White Carlos Vozzi Eduardo Balcells Michael Ragosta C Edwin Martin Vankeepuram S Srinivas William W Wharton III Staci Abramsky Ana C Mon Shari S Kronsberg Judith S Hochman 2010World Journal of Cardiology2010,2,1:1
