姑息性胃切除联合术后化疗评分在腹膜转移的胃癌患者预后评估中的临床意义

目的:探讨姑息性胃切除联合术后化疗评分在腹膜转移的胃癌患者预后评估中的临床意义。方法:回顾性分析2010年1月至2016年12月7年间收治的287例发生腹膜转移的胃癌患者的临床病理资料。通过χ2检验分析评分与患者临床病理因素间的关系。通过Kaplan-Meier法绘制生存曲线，Log-rank检验比较患者生存率的差异；采用Cox比例风险回归模型对患者进行预后分析。结果:与评分中得分为2分和1分的患者相比，得分为0分的患者肿瘤侵润至T4b 期的患者较少［31%(18/58)比50.8%(63/124)、56.2%(59/105)，P=0.039］。全组患者的中位生存时间仅为8.7月。对患者进行单因素预后分析结果显示，血清白蛋白浓度（≤40 g/L），腹水，腹膜转移范围较大，肿瘤T分期较晚，评分得分较高的患者预后较差（均P＜0.05）。将上述因素纳入Cox多因素分析结果显示:评分［HR（95%CI）:1.384（1.165~1.644），P=0.000］，血清白蛋白浓度［HR（95%CI）:0.759（0.593~0.971），P=0.028］，肿瘤T分期［HR（95%CI）:1.493（1.216~1.832），P=0.000］是患者预后的独立危险因素。结论:评分对于胃癌伴腹膜转移患者的预后生存评估具有重要的临床意义。     

Recommendations for prevention and management of COVID-19 in peritoneal dialysis patients

The World Health Organization characterized coronavirus disease (COVID-19) as a pandemic on March 11, 2020. Peritoneal dialysis patients have a weakened immune system that is associated with a high morbidity of infection. Thus, COVID-19 prevention measures and management for patients on peritoneal dialysis are urgent and critical. Based on published research on COVID-19 and previous clinical practices for similar coronavirus outbreaks, we aimed to make recommendations to manage patients undergoing peritoneal dialysis.     

胃癌患者根治术后腹腔灌洗液中CEA mRNA表达的临床意义

目的：探讨胃癌患者根治术后腹腔冲洗液中CEA mRNA表达情况及其临床意义。方法: 回顾性分析了2013 年1 月至2017 年12 月在南京大学医学院附属鼓楼医院接受胃癌根治切除术后进行腹腔灌洗液CEA mRNA检测的139 名患者的病历资料，并进行术后常规随访。用RT-PCR检测139 胃癌患者根治术后腹腔灌洗液中CEA mRNA表达情况。卡方检验分析腹腔灌洗液中CEA mRNA表达与临床基本特征、组织病理学资料、血液学指标及复发方式之间的关系。采用Logistic 单因素及多因素回归分析筛查影响CEA mRNA表达水平的因素。结果：139 名患者中44 名（31.7%）患者腹腔灌洗液CEA mRNA阳性。分析显示，胃癌患者腹腔灌洗液CEA mRNA阳性表达与性别、年龄、病理分级、Lauren 分型和HER2、EGFR、VEGFR等标记物间均没有明显的关联（均P>0.05），与病理类型、脉管是否侵犯、局部浸润深度、淋巴结转移程度和临床AJCC 分期有明显的关联（均P<0.05）。CEA mRNA阳性患者腹膜复发率明显高于阴性患者（P=0.012）。Logistic 单因素回归分析显示，印戒细胞癌（P=0.04，HR=2.810，95% CI: 1.050~7.520）、T 分期（P=0.016，HR=6.329，95% CI: 1.417~28.264）、N 分期（P=0.022，HR=3.068，95% CI: 1.172~8.027）、AJCC分期（P=0.016 ，HR=3.971 ，95% CI: 1.295~12.173 ）、神经侵犯（P=0.002 ，HR=6.738，95% CI: 1.995~22.757）、脉管侵犯（P<0.001，HR=16.36，95% CI: 3.85~69.512）为胃癌患者腹腔灌洗液CEA mRNA阳性表达的危险因素。Logistic 多因素回归分析显示，经过对其他因素的校正，脉管侵犯（P<0.001，HR=21.314，95% CI: 4.21~107.907）为胃癌患者腹腔灌洗液CEA mRNA阳性表达的独立危险因素。结论：胃癌腹腔灌洗CEA mRNA阳性的患者腹膜复发转移风险高且预后不良，应考虑包括腹腔局部治疗在内的更加积极的抗肿瘤治疗。     

Analysis of early mortality and related risk factors in maintenance hemodialysis patients

Objective To analyze the early mortality and related risk factors of new hemodialysis patients in Zhejiang province, and provide basis for reducing the death risk of hemodialysis patients. Methods The early mortality and related factors of new hemodialysis patients from January 1, 2010 to June 30, 2018 were retrospectively analyzed using the database of Zhejiang province hemodialysis registration. The early mortality was defined as death within 90 days of dialysis. Cox regression model was used to analyze the related risk factors of the early mortality in hemodialysis patients. Results The mortality was the highest in the first month after dialysis (46.40/100 person year), and gradually stabilized after three months. The early mortality was 25.33/100 person year. The mortality within 120 days and 360 days were 21.40/100 person year and 11.37/100 person year, respectively. The elderly (≥65 years old, HR=1.981, 95%CI 1.319-2.977, P＜0.001), primary tumor (HR=3.308, 95%CI 1.137-5.624, P=0.028), combined with tumors (not including the primary tumor, HR=2.327, 95%CI 1.200-4.513, P=0.012), temporary catheter (the initial dialysis pathway, HR=3.632, 95%CI 1.806-7.307, P＜0.001), lower albumin (＜30 g/L, HR=2.181, 95%CI 1.459-3.260, P＜0.001), lower hemoglobin (every 0.01 g/L increase, HR=0.861, 95%CI 0.793-0.935, P=0.001), lower high density lipoprotein (＜0.7 mmol/L, HR=1.796, 95%CI 1.068-3.019, P=0.027) and higher C reactive protein (≥40 mg/L, HR=1.889, 95%CI 1.185-3.012, P=0.008) were the risk factors of early death for hemodialysis patients. Conclusions The early mortality of hemodialysis patients is high after dialysis, and gradually stable after 3 months. The elderly, primary tumor, combined with tumors, the initial dialysis pathway, lower albumin, lower hemoglobin, lower high density lipoprotein and higher C reactive protein are the risk factors of early death for hemodialysis patients.

Peroperative scoring systems for predicting the outcome of cytoreductive surgery in advanced-stage ovarian cancer – A systematic review

The extent of peritoneal metastases (PM) largely determines the possibility of complete or optimal cytoreductive surgery in advanced ovarian cancer. An objective scoring system to quantify the extent of PM can help clinicians to decide whether or not to embark on CRS. Therefore several scoring systems have been developed by different research teams and this review summarizes their performance in predicting a complete or optimal cytoreduction in patients with advanced ovarian cancer. A systematic search in the MEDLINE database revealed 19 articles that described a total of five main scoring systems to predict the completeness of CRS in patients with FIGO stage III-IV ovarian cancer based on the surgical exploration of the abdominal cavity; PCI, PIV, Eisenkop, Espada, and Kasper. The Peritoneal Cancer Index (PCI) and the Predictive Index Value (PIV) were mentioned most frequently and showed AUCs of 0.69–0.92 and 0.66–0.98, respectively. Due to the use of different cut-offs sensitivities and specificities greatly varied. Therefore with the current data, no scoring system could be identified as best. An objective measure of the extent of disease can be of great clinical use for identifying ovarian cancer patients for which a complete (or optimal) CRS is achievable, however due to local differences in treatment strategies and surgical policy a widely adopted objective scoring system with a standard cut-off value is not feasible. Nevertheless, objective scoring systems can play an important role to guide treatment decisions.
