Since February 2nd, 2018, the journal "Medical Radiology and Radiation Safety" has been indexed in the SCOPUS abstract and citation database.
Brief electronic versions of the Journal have been publicly available since 2005 on the website of the Medical Radiology and Radiation Safety Journal: http://www.medradiol.ru. Since 2011, all issues of the journal as a whole are publicly available, and since 2016 - full-text versions of scientific articles. Since 2005, subscribers can purchase full versions of other articles of any issue only through the National Electronic Library. The editor of the Medical Radiology and Radiation Safety Journal in accordance with the National Electronic Library agreement has been providing the Library with all its production since 2005 until now.
The main working language of the journal is Russian, an additional language is English, which is used to write titles of articles, information about authors, annotations, key words, a list of literature.
Since 2017 the journal Medical Radiology and Radiation Safety has switched to digital identification of publications, assigning to each article the identifier of the digital object (DOI), which greatly accelerated the search for the location of the article on the Internet. In future it is planned to publish the English-language version of the journal Medical Radiology and Radiation Safety for its development. In order to obtain information about the publication activity of the journal in March 2015, a counter of readers' references to the materials posted on the site from 2005 to the present which is placed on the journal's website. During 2015 - 2016 years on average there were no more than 100-170 handlings per day. Publication of a number of articles, as well as electronic versions of profile monographs and collections in the public domain, dramatically increased the number of handlings to the journal's website to 500 - 800 per day, and the total number of visits to the site at the end of 2017 was more than 230.000.
The two-year impact factor of RISC, according to data for 2017, was 0.439, taking into account citation from all sources - 0.570, and the five-year impact factor of RISC - 0.352.

Abstract
Purpose: Comparative analysis of the overall survival (OS) in different subgroups of the patients with non-small cell lung cancer (NSCLC) with affected mediastinal lymph nodes (pN2) after surgical and combined treatment using postoperative radiotherapy (PORT).
Material and methods: A comparative assessment of the overall survival of 243 patients with NSCLC stages IIIA, IIIB (рT1–4N2M0) was carried out: the I group – 79 patients after radical (R0) surgical treatment (lobe/bilobectomy, pulmonectomy with ipsilateral mediastinal lymph node dissection) and the second group – 164 patients after the combined modality therapy with the same volume of surgery and postoperative radiotherapy in the mode of hypofractionation (daily dose 3 Gy, 5 times a week, TD = 36–39 Gy (EQD2 = 43.2–46.8 Gy, α/β = 3) or classical fractionation (2 Gy, 5 times a week, TD = 44 Gy). We analyzed subgroups of men and women, patients younger than 60 years and older, with central and peripheral cancer, squamous cell carcinoma and adenocarcinoma, with different gradation of tumors according to the criterion T (pT1–4).
Results: In the compared groups, 2-year and 5-year OS was significantly higher in the PORT group (62.4 and 31.6 vs 44.8 % and 12.3 %, p = 0.0028), at the expense of male patients (62.4 and 31.6 % vs 44.8 and 12.3 %, p = 0.0028), patients with central cancer (59.2 and 43.7 % vs 36.3 % and n/a, p = 0.0023), patients with squamous cell carcinoma (64.0 % and 43.1 % vs 42.3 % and 6.7 %, p = 0.0006), patients older than 60 years (74.8 and 46.2 % vs 45.1 % and n/a, p = 0.007). A more detailed analysis revealed that PORT significantly increased 2- and 5-year OS in the central squamous cell carcinoma of the lung (67.3 and 53.0 % vs. 33.3 and 0 %, respectively, p = 0.0013), and in pT3–4 tumors (2-year OS 57.1 vs. 36.4 %, respectively, p = 0.0102). There was only a tendency of increasing OS after the PORT in T2 tumors (5-year OS 31.1 vs 15.4 %, respectively, p = 0.1319). In T1 tumors, no differences in OS were found, possibly due to the small number of cases (27). In peripheral squamous cell carcinoma there was a statistically insignificant increasing of 5-year OS – 7 %. There was no significant differences in OS survival were obtained in central and peripheral lung adenocarcinoma between the I and II groups.
Conclusion: In the patients with non-small cell lung cancer pN2, radically operated (R0) in the volume of lobe/bilobectomy, pulmonectomy with ipsilateral mediastinal lymph node dissection, PORT can be recommended for central squamous cell carcinoma pT1–4. In the patients with peripheral squamous cell carcinoma, PORT can be discussed for the patients with individually assessed high risk of the locoregional relapse. PORT, within the scope of irradiation and total doses used in this study, has no age restrictions. The feasibility of PORT for radically operated patients with pN2 lung adenocarcinoma requires further study.
