The aim of this study was to explore the independent prognostic factors related to postoperative recurrence‐free survival (RFS) in patients with breast phyllodes tumors (PTBs). A retrospective analysis was conducted in Fudan University Shanghai Cancer Center. According to histological type, patients with benign PTBs were classified as a low‐risk group, while borderline and malignant PTBs were classified as a high‐risk group. The Cox regression model was adopted to identify factors affecting postoperative RFS in the two groups, and a nomogram was generated to predict recurrence‐free survival at 1, 3, and 5 years. Among the 404 patients, 168 (41.6%) patients had benign PTB, 184 (45.5%) had borderline PTB, and 52 (12.9%) had malignant PTB. Fifty‐five patients experienced postoperative local recurrence, including six benign cases, 26 borderline cases, and 22 malignant cases; the three histological types of PTB had local recurrence rates of 3.6%, 14.1%, and 42.3%, respectively. Stromal cell atypia was an independent prognostic factor for RFS in the low‐risk group, while the surgical approach and tumor border were independent prognostic factors for RFS in the high‐risk group, and patients receiving simple excision with an infiltrative tumor border had a higher recurrence rate. A nomogram developed based on clinicopathologic features and surgical approaches could predict recurrence‐free survival at 1, 3, and 5 years. For high‐risk patients, this predictive nomogram based on tumor border, tumor residue, mitotic activity, degree of stromal cell hyperplasia, and atypia can be applied for patient counseling and clinical management. The efficacy of adjuvant radiotherapy remains uncertain.
It used GIS approach to manage the distribution network, and it has a comprehensive analysis in the distribution network management system. It provide the distribution of professional management decision analysis that can greatly facilitate the management of the distribution network of various types of data, while the planning and management process more direct and interactive. This paper describes the application of GIS in Distribution Network.
This paper describes a wind power monitoring software design ideas, and its design focus is the client software monitoring platform for wind farm monitoring. In this paper, for the characteristics and requirements of the wind turbine monitoring system, it involved the design of the wind farm monitoring software design architecture, the design of the monitoring system to achieve real-time display of wind turbine production data, alarms, historical data storage and query, report generation and other operations, achieve the production site for real-time monitoring of wind turbines.
469 Background: Patients with gastroenterpancreatic neuroendocrine carcinomas (NECs) have a very poor prognosis. And the role of the second-line therapy remains unknown. Methods: We retrospectively analyzed 11 patients with gastroenteropancreatic NEC after failure of first-line chemotherapy in the last two years in our cancer center. Data examined included clinical and pathological characteristics at the time of diagnosis, efficacy and safety. Results: Median age was 51 (17-64) years old. Most were male (81.8%). Tumor origin included pancreas (6pts, 54.5%), colon-rectum (3pts, 27.3%), one stomach and one liver. Metastatic disease was evident at diagnosis in all patients (liver metastases: 100%, celiac lymph nodes: 72.7%, bone: 18.2%, pleural effusion and peritoneal metastasis: 18.2%). Median Ki-67 index was 80%. Etoposide-cisplatin combinations as first line chemotherapy were administered in 8 (72.7%) patients and 2 (18.2%) capecitabine based regimen and 1(9.1%) gemcitabine with nab-paclitaxel. All patients received the FOLFIRI regimen with a median number of 8 (3-36) courses. Three patients (27.3%) had partial response, 4 (36.4%) stable disease, and 4 (36.4 %%) tumor progression. But in 6 patients received the FOLFIRI plus bevacizumab, disease control rate was 66.7%, 3 (50.0%) partial response, 1(16.7%) stable disease. The median PFS in all 11 pts was 3.77 (1.77-24.07) months, in 6pts with bevacizumab was 4.77(1.83-24.07) months. The most severe toxicities was grade 3 neutropenia (27.2%), the other adverse effects were mild to moderate, including mild anemia, transient transferase elevation and proteinuria. Conclusions: FOLFIRI regimen is a potentially effective and safe chemotherapy given as second-line in patients with NEC. Additional anti-VEGF therapy with bevacizumab may improve the disease control and PFS time.
This paper finds that the elevated building normally located in Chongqings mountainous areas can be optimized in both integral structure and individual elements. Through the calculation of typical structure, the weaknesses of elevated building are the unevenness of the internal force caused by external loads and the over-length of supporting bars. Meanwhile, through the way of numerical modeling which uses the features of two-dimensional member bar system, specific solutions are pointed out. The conclusion can be drawn through the analysis of results and data that the more direct the method of transferring force is, the more stable the structure is. In addition, within the experience of practical engineering programs, strengths and weaknesses are also put forward through comparing measures within themselves, which can enhance the ability to resist the impulsive or extreme external force.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
