Gastric cancer prognosis remains problematic because of still high recurrence of peritoneal metastasis. Therefore, the detection of tumour cells in the abdominal cavity is of great prognostic value. The study aims to compare groups of patients with positive and negative cytological washings from the peritoneum in the 10-year term. We used data from patients with morphologically verified gastric cancer, who received radical surgical treatment in the abdominal oncology department of the Sverdlovsk Regional Oncologi Dispensary, in the period from 2008 to 2011. The sample included 142 cases. The patients were divided into 2 groups according to the presence of a positive (Cyt +) or negative (Cyt-) washout from the peritoneum, 58 and 84 cases accordingly. Intra-abdominal hyper thermo chemo perfusion (HIPEC) was performed in 20 patients from the (Cyt +) group, and 38 patients received adequate surgical treatment. Long-term 10-year results were analysed in 119 patients. We assessed the 10-year survival rate depending on the depth of invasion (≥T3), patients (Cyt +) and HIPEC was 8%. However, the 10-year survival rate without the use of HIPEC was not achieved. In our study, the presence of (Cyt +), determines the decrease in survival rate in the 10-year period, regardless of (≥T3); (G1-G2) and (G3-G4).The use of the HIPEC technique in patients (Cyt +) determines an increase in survival from 0% to 8% and a follow-up period from 50 months to 120 months.
胃癌的预后仍有问题,因为腹膜转移的复发率仍然很高。因此,腹腔肿瘤细胞的检测具有重要的预后价值。该研究旨在比较10年内腹膜细胞学冲洗阳性和阴性的患者组。我们使用的数据来自2008年至2011年期间在斯维尔德洛夫斯克地区肿瘤药房腹部肿瘤科接受根治性手术治疗的经形态学证实的胃癌患者。样本包括142例。根据腹膜淋巴细胞阳性(Cyt +)和阴性(Cyt-)冲洗情况分为两组,分别为58例和84例。(Cyt +)组20例患者行腹腔超热化疗灌注(HIPEC), 38例患者接受了充分的手术治疗。对119例患者的10年长期结果进行了分析。我们根据浸润深度(≥T3)、患者(Cyt +)和HIPEC评估10年生存率为8%。然而,未使用HIPEC的10年生存率未达到。在我们的研究中,(Cyt +)的存在决定了10年期间生存率的下降,无论(≥T3);(G1-G2)和(G3-G4)。在患者(Cyt +)中使用HIPEC技术决定了生存率从0%增加到8%,随访时间从50个月到120个月。

namely, mass open online courses in student communities. This approach allows you to carry out educational activities regardless of the student's location, his initial level of subject training. It makes it possible to increase motivation for the learning process, eliminate subjective factors in the assessment system, and build an individual educational route. The article discusses the educational opportunities of distance learning technologies for organizing online classes' work as a mass open online course in students' network community. The network community allows for interactive online interaction of its members through computer technologies, messengers, and social networks. The course «Preparing students for the Unified State Exam in Mathematics (profile level)» was implemented on the Miroznai platform of the Volgograd State Socio-Pedagogical University. Variants of interaction in online communities of teachers and students are considered; examples of introducing the content of training sessions and monitoring the learning level are given. The effectiveness of studying the course in both disciplinary and metadisciplinary training of students is shown. Thus, in the control group, the percentage of task completion was lower than in the experimental group; we note that the control group consisted of students studying in isolation, outside the network community. The result of students' metadisciplinary training was the ability to: interact productively in a network community; use computer technology tools to organize independent work on the search, analysis, and presentation of the received information.
即在学生群体中大规模开放网络课程。这种方法允许您开展教育活动,而不管学生的位置,他的初始学科培训水平。它可以增加学习过程的动机,消除评估系统中的主观因素,建立个性化的教育路线。本文探讨了远程学习技术在学生网络社区组织网络课堂工作的教育机会。网络社区允许其成员通过计算机技术、信使和社交网络进行在线互动。课程“为学生准备国家统一数学考试(简介级)”在伏尔加格勒国立社会教育大学的Miroznai平台上实施。考虑了教师和学生在线社区互动的变体;给出了介绍培训课程内容和监控学习水平的例子。本课程的学习对学生的学科训练和跨学科训练都有一定的效果。因此,在对照组中,任务完成率低于实验组;我们注意到,控制组由在网络社区之外孤立学习的学生组成。学生的元学科训练的结果是:在网络社区中进行有效互动的能力;使用计算机技术工具组织对所接收信息的搜索、分析和呈现的独立工作。
