We examined patterns of follow-up care and identified characteristics associated with the frequency of radiation oncology (RO) visits during survivorship. We conducted a population-based cohort study of men diagnosed with prostate cancer between April 2010 and March 2019 in Ontario, Canada, who underwent first-line radiotherapy. Survivorship began three years following radiation. Using a recurrent event framework, we identified demographic and clinical characteristics associated with the rate of RO follow-up. Survivors seeking RO follow-up declined by 46.2% over five years of survivorship. Higher-risk characteristics, such as higher ISUP grade, higher stage, detectable prostate-specific antigen (PSA) score, and receipt of brachytherapy and\/or hormones, were associated with more frequent RO visits. For instance, relative to International Society of Urological Pathology (ISUP) Grade 1, those with Grades 3 through 5 experienced follow-up rates that were 20%, 25%, and 34% higher, respectively. Despite concordance between patient risk and rate of RO follow-up, 23.6% of survivors continued to visit their RO providers into their fifth year of survivorship, more than half of whom were ISUP grades 1\u20132. Primary care follow-up remained stable. While frequency of RO follow-up appropriately reflected patient risk profile, many low-risk survivors still sought long-term RO-led care. This suggests an opportunity to encourage lower-risk prostate cancer survivors to seek follow-up care with their general practitioner.<\/jats:p>","DOI":"10.3390\/curroncol33010049","type":"journal-article","created":{"date-parts":[[2026,1,15]],"date-time":"2026-01-15T11:13:21Z","timestamp":1768475601000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Radiation Oncology Follow-Up of Prostate Cancer Survivors Following Completion of Radiotherapy: A Population-Based Study"],"prefix":"10.3390","volume":"33","author":[{"given":"Joshua O.","family":"Cerasuolo","sequence":"first","affiliation":[{"name":"Department of Health Research Methods, Evidence, and Impact, Faculty of Health Sciences, McMaster University, Hamilton, ON L8N 3Z5, Canada"},{"name":"ICES McMaster, Faculty of Health Sciences, McMaster University, Hamilton, ON L8S 4L8, Canada"},{"name":"ICES North, Health Sciences North Research Institute, Sudbury, ON P3E 2H2, Canada"},{"name":"Medical Sciences Division, NOSM University, Sudbury, ON P3E 2C6, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7702-8816","authenticated-orcid":false,"given":"Jonathan","family":"Sussman","sequence":"additional","affiliation":[{"name":"Department of Oncology, Faculty of Health Sciences, McMaster University, Hamilton, ON L8V 5C2, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian S.","family":"Dayes","sequence":"additional","affiliation":[{"name":"Department of Oncology, Faculty of Health Sciences, McMaster University, Hamilton, ON L8V 5C2, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rinku","family":"Sutradhar","sequence":"additional","affiliation":[{"name":"ICES, Toronto, ON M4N 3M5, Canada"},{"name":"Dalla Lana School of Public Health, University of Toronto, Toronto, ON M5T 3M7, Canada"},{"name":"Institute of Health Policy, Management, and Evaluation, University of Toronto, Toronto, ON M5T 3M6, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5052-4828","authenticated-orcid":false,"given":"Manaf","family":"Zargoush","sequence":"additional","affiliation":[{"name":"Health Policy and Management Area, DeGroote School of Business, McMaster University, Hamilton, ON L8S 4M4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6701-1714","authenticated-orcid":false,"given":"Hsien","family":"Seow","sequence":"additional","affiliation":[{"name":"Department of Health Research Methods, Evidence, and Impact, Faculty of Health Sciences, McMaster University, Hamilton, ON L8N 3Z5, Canada"},{"name":"ICES McMaster, Faculty of Health Sciences, McMaster University, Hamilton, ON L8S 4L8, Canada"},{"name":"Department of Oncology, Faculty of Health Sciences, McMaster University, Hamilton, ON L8V 5C2, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,15]]},"reference":[{"key":"ref_1","unstructured":"Canadian Cancer Statistics Advisory Committee in collaboration with the Canadian Cancer Society, and Statistics Canada and the Public Health Agency of Canada (2023, June 05).
