Oncologists rely on specific patient and tumour characteristics to recommend modern-day treatments. However, some of this information may not have been available during prior periods in which the evidence was generated. For example, the comprehensive Early Breast Cancer Trialists\u2019 Collaborative Group (EBCTCG) meta-analyses published in the 2000s typically included older trials accruing patients between the 1960s and 1980s. This raises some uncertainty about whether conclusions from studies conducted in prior eras are as relevant or applicable to modern-day patients and treatments. Reviewing the chronological order and details of the evidence can be beneficial to understanding these nuances. This review discusses the evolution of locoregional management through some key clinical trials. We aim to highlight the time period in which the evidence was generated and emphasize the 10-year outcomes for the comparability of results. Evidence supporting surgical management of the breast and axilla, as well as details of radiotherapy are discussed briefly for all stages of breast cancer.<\/jats:p>","DOI":"10.3390\/curroncol29070369","type":"journal-article","created":{"date-parts":[[2022,7,2]],"date-time":"2022-07-02T11:12:35Z","timestamp":1656760355000},"page":"4647-4664","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Locoregional Management of Breast Cancer: A Chronological Review"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4231-2945","authenticated-orcid":false,"given":"Abdulla","family":"Al-Rashdan","sequence":"first","affiliation":[{"name":"Dalhousie University School of Medicine, Dalhousie University, Halifax, NS B3H 1V7, Canada"},{"name":"Cumming School of Medicine, University of Calgary, Calgary, AB T2N 1N4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melina","family":"Deban","sequence":"additional","affiliation":[{"name":"Cumming School of Medicine, University of Calgary, Calgary, AB T2N 1N4, Canada"},{"name":"Division of Radiation Oncology, Tom Baker Cancer Centre, 1331 29 St. NW, Calgary, AB T2N 4N2, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"May Lynn","family":"Quan","sequence":"additional","affiliation":[{"name":"Cumming School of Medicine, University of Calgary, Calgary, AB T2N 1N4, Canada"},{"name":"Division of Radiation Oncology, Tom Baker Cancer Centre, 1331 29 St. NW, Calgary, AB T2N 4N2, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey Q.","family":"Cao","sequence":"additional","affiliation":[{"name":"Cumming School of Medicine, University of Calgary, Calgary, AB T2N 1N4, Canada"},{"name":"Division of Radiation Oncology, Tom Baker Cancer Centre, 1331 29 St. NW, Calgary, AB T2N 4N2, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"VII","DOI":"10.1590\/0100-3984.2014.47.4e2","article-title":"Mammography: A history of success and scientific enthusiasm","volume":"47","author":"Kalaf","year":"2014","journal-title":"Radiol.
