This study explored key research topics and emerging trends in studies related to PA and HRQoL among breast cancer survivors. Methods: Titles and abstracts of 3847 English-language research articles (2000\u20132024) were retrieved from PubMed, EMBASE, Web of Science, and Scopus using keywords related to \u2018breast cancer\u2019, \u2018PA\/exercise\u2019, and \u2018HRQoL\u2019. A text-mining algorithm based on the Dirichlet-multinomial regression approach in Python was applied to identify the top 10 research topics and their trends over time. Results: In total, 10 key topics emerged: (1) Quality of Life and Well-being, (2) Cancer Treatment and Health-Related Fitness, (3) Supportive Care and Psychosocial Factors, (4) Survivorship, Palliative Care, and Integrative Medicine, (5) Physical Activity and Sedentary Behaviors, (6) Upper Limb-Related Side Effects, (7) Cancer-Related Fatigue and Symptoms, (8) Epidemiological and Clinical Factors, (9) Side Effects of Cancer Treatment, and (10) Weight Management. Among these, Topics 1, 2, 3, 8, and 9 followed upward trajectories, while others showed relatively stable trends. Conclusions: Findings highlight that PA research on breast cancer survivors\u2019 HRQoL spans all stages of survivorship and considers both clinical outcomes and psychosocial and emotional well-being. Understanding how PA and HRQoL have been represented in research helps clarify which survivor needs have received attention and which remain underexplored. These thematic patterns underscore growing acknowledgement of survivors\u2019 lived experiences and offer a roadmap for addressing future research and care gaps.<\/jats:p>","DOI":"10.3390\/jcm14165615","type":"journal-article","created":{"date-parts":[[2025,8,8]],"date-time":"2025-08-08T11:41:53Z","timestamp":1754653313000},"page":"5615","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Landscape of Physical Activity and Quality of Life Research in Breast Cancer Survivors: Topic Modeling Analysis"],"prefix":"10.3390","volume":"14","author":[{"given":"Suryeon","family":"Ryu","sequence":"first","affiliation":[{"name":"Center for Children\u2019s Healthy Lifestyles & Nutrition, Children\u2019s Mercy Hospital, Kansas City, MO 64108, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ki-Yong","family":"An","sequence":"additional","affiliation":[{"name":"Faculty of Kinesiology, Sport, and Recreation, University of Alberta, Edmonton, AB T6G 2H9, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Library and Information Science, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul 03722, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6037-0439","authenticated-orcid":false,"given":"Zan","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, Recreation, and Sport Studies, The University of Tennessee, Knoxville, TN 37996, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,8]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2025, May 12).
