The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

RESUMO

Radiotherapy and chemotherapy cause genotoxic side effects that are highly variable among patients. In this study, we evaluated DNA integrity using the comet assay in peripheral blood lymphocytes from breast cancer patients before ("pre-treatment patients"; n = 47) and after ("post-treatment patients"; n = 24) radiotherapy and/or chemotherapy treatment and from healthy donors (n = 15). Comet evaluation was made by visual (types 0−4) and digital (percentage of DNA remaining in the comet head = % head DNA) analysis. The association between the level of DNA damage and cancer prognostic factors was assessed. The treatments caused a significant increase in DNA damage registered by both visual (p < 0.001) and digital (p < 0.001) analyses. No significant associations between the level of DNA damage in pre-treatment patients and cancer prognostic factors were found. A significant correlation between the comet results from each patient before and after treatment (r = 0.64, p = 0.001) was observed. The % head DNA in post-treatment samples from patients with a high level of DNA damage before treatment (30.3 ± 3.1%, p < 0.01) was lower than in post-treatment samples from patients with a low-to-medium level of DNA damage before therapy (49.2 ± 4.4%). These results support the usefulness of the comet assay as a sensitive technique to evaluate basal DNA status and DNA damage caused by cancer treatments. The comet assay could contribute to treatment decisions, especially by taking into account the patient's basal DNA damage before therapy.
