Study on road network model based on virtual node joint

Zhu Zhuangsheng,Wang Qing,Wan Dejun

Strategic Study of CAE 2009, Volume 11, Issue 8, Pages 83-87

Abstract: text-align: justify;">The road network in the real world has been showed by the road network model based on nodeIt is the first time that a novel road network model,that is,the road network model based on virtualnode joint,was presented in the paper to eliminate the limitations.The novel model adops virtual node to show multi-road converging area,and the virtual node is an areaThe novel model has better of image the traffic flow on the road network than the old model based on node

Clinical significance of para-aortic lymph node dissection and prognosis in ovarian cancer

Xianxian Li, Hui Xing, Lin Li, Yanli Huang, Min Zhou, Qiong Liu, Xiaomin Qin, Min He

Frontiers of Medicine 2014, Volume 8, Issue 1, Pages 96-100 doi: 10.1007/s11684-014-0316-4

Abstract:

Lymph node metastasis has an important effect on prognosis of patients with ovarian cancer.Moreover, the impact of para-aortic lymph node (PAN) removal on patient prognosis is still unclear.Group A consisted of 30 patients who underwent PAN+ pelvic lymph node (PLN) dissection, whereas groupIn group B, 13 cases were positive for lymph node metastasis.Our study suggested that the metastatic rate of lymph node is 40.0%.

Prognostic value of the 21-gene recurrence score in ER-positive, HER2-negative, node-positive breastcancer was similar in node-negative diseases: a single-center study of 800 patients

Jiayi Wu, Weiqi Gao, Xiaosong Chen, Chunxiao Fei, Lin Lin, Weiguo Chen, Ou Huang, Siji Zhu, Jianrong He, Yafen Li, Li Zhu, Kunwei Shen

Frontiers of Medicine 2021, Volume 15, Issue 4, Pages 621-628 doi: 10.1007/s11684-020-0738-0

Abstract: Multi-gene assays have emerged as crucial tools for risk stratification in early-stage breast cancer. This study aimed to evaluate the prognostic significance of the 21-gene recurrence score (RS) in Chinese patients with pN0-1, estrogen receptor-positive (ER ), human epidermal growth factor receptor 2-negative (HER2 ) breast cancer. Among 800 patients recruited between 2009 and 2016, the median RS was 24 (0–69), with 27.4%, 46.8%, and 25.9% patients classified into low-, intermediate-, and high-risk groups. Cox regression analysis demonstrated that the high-risk category was associated with significantly higher odds of invasive disease-free survival (IDFS) and distant disease-free survival (DDFS) events compared with the low-risk category (IDFS: HR= 2.450, 95% CI 1.017–5.902, = 0.046; DDFS: HR= 2.829, 95% CI 1.013–7.901, = 0.047). No significant association between RS category and overall survival (OS) was found (intermediate vs. low: HR= 1.244, 95% CI 0.292–5.297, = 0.768; high vs. low: HR= 2.933, 95% CI 0.759–11.327, = 0.119). RS, as a continuous variable, was a highly significant predictor for IDFS (HR= 1.028, 95% CI 1.010–1.047, = 0.002), DDFS (HR= 1.030, 95% CI 1.010–1.051, = 0.003), and OS (HR= 1.034, 95% CI 1.007–1.063, = 0.014). Our findings suggested that RS may predict IDFS in Chinese patients with ER /HER2 breast cancer with N0 or N1 disease.

Application progress of lymphography in oncology

Yang YU, Jibin LIU, Lixue YIN

Frontiers of Medicine 2009, Volume 3, Issue 1, Pages 13-19 doi: 10.1007/s11684-009-0016-7

Abstract: Lymphography is often used for the diagnosis of lymphatic metastasis in oncology. Determination of lymphatic metastasis is extremely important for accurate cancer staging, which may directly guide the clinical therapeutic scheme. In recent years, the technology of lymphography has developed rapidly on the basis of traditional lymphography, with the appearance of computed tomography (CT) lymphography, nuclear magnetic resonance (MR) lymphography, contrast-enhanced lymphosonography, and so on; the diagnostic accuracy has also been improved. The imaging principles and methods of these various technologies of lymphography are reviewed in this paper, and their applications and significance in oncology are also discussed in detail.
