In situ breast cancer incidence patterns in Iceland and differences in ductal carcinoma in situ treatment compared to Sweden

The purpose was to review the incidence of in situ carcinoma in Iceland after initiating population-based mammography screening in 1987 and to compare management of ductal carcinoma in situ (DCIS) between Iceland and the Uppsala–Örebro region (UÖR) in Central Sweden. The Icelandic Cancer Registry provided data on in situ breast carcinomas for women between 1957 and 2017. Clinical data for women with DCIS between 2008 and 2014 was extracted from hospital records and compared to women diagnosed in UÖR. In Iceland, in situ carcinoma incidence increased from 7 to 30 per 100 000 women per year, following the introduction of organised mammography screening. The proportion of in situ carcinoma of all breast carcinomas increased from 4 to 12%. More than one third (35%) of women diagnosed with DCIS in Iceland were older than 70 years versus 18% in UÖR. In Iceland, 49% of all DCIS women underwent mastectomy compared to 40% in UÖR. The incidence of in situ carcinoma in Iceland increased four-fold after the uptake of population-based mammography screening causing considerable risk of overtreatment. Differences in treatment of DCIS were seen between Iceland and UÖR, revealing the importance of quality registration for monitoring patterns of management.

Commissioning experience of the X-ray volume imaging system of an image-guided radiotherapy capable linear accelerator

Aim: An image-guided radiotherapy capable linear accelerator was installed at our hospital which is equipped with an X-ray volumetric imaging (XVI) system. The aim of this study was to describe the results of acceptance tests which were carried out on the XVI facility to verify the manufacturer’s specification. Materials and methods: The commissioning test had six elements: system safety, geometric accuracy, image quality, registration and correction accuracy, X-ray tube and generator performance, and quality assurance (QA) procedures. Results: We had satisfactory results for all the tests. The system passed the safety testes, and the agreement of isocentres was found to be within the tolerance limit. Imaging quality was acceptable. Registration and correction accuracy was tasted with indigenously developed phantom and positioned accurately at isocentre. X-ray tube and generator test results showed that the tube was performing properly. Findings: The described tests represent that the performance of the system is maintained at acceptable levels.

THE ORGANIZATION OF WORK OF THE PRINTING INDUSTRY IN AGAIN FORMED SUBJECT – KRASNODAR TERRITORY

PERFORMANCE ANALYSIS OF SERVICE STATION

In activity the analysis of the existing researches devoted to a question of raise of overall performanceof technical stations which extra execute functions of the boundary transmitting is carried out. International shipping terms by rail significantly differ from condition of carriages of freights in regional traffic.The main problems which exist now in activity of such stations, are linked to delays of the coaches following in the interstate message. It is analyzed parametres of activity of technical station which is disposed on a joint of a track of 1520 mms and 1435 mms.The analysis showed availability of significant figure of delays of coaches because of poor-quality registration of carriage documents, imperfections of interaction of points of transfers export-import to a traffic volume. This absence of the customs declaration, absence of the permission of veterinary service, commercial marriage, absence of a calendar stamp and others. It demands the further enhancement of an informational inter-system of functioning of technicalstations and adjacent state organisations.
