Understanding weight trajectories will help inform breast cancer survivors at greater risk of weight gain, and those who would benefit from earlier anti-obesity interventions. We performed a retrospective chart review of women from the Breast Cancer Program Longitudinal Repository (BCPLR) at Johns Hopkins diagnosed with hormone receptor-positive Stage I-III breast cancer from 2010 to 2020. We investigated obesity (measured by body mass index [BMI]) over time, patient and tumor characteristics, as well as treatment and recurrence. We observed a significant \u22655% increase in BMI from diagnosis to most recent follow-up (p = 0.009), particularly among those who were overweight at diagnosis (p = 0.003). Additionally, among those up to 5 years since diagnosis, there was a significant association between experiencing a \u22650.1 kg\/m2 increase per year since diagnosis and baseline BMI status (p = 0.009). A \u22650.6 kg\/m2 decrease in BMI was observed for participants with obesity at diagnosis (p = 0.006). Our study highlights (i) the significant burden of obesity in women with a history of breast cancer and (ii) higher risks for increases in BMI and shifts in class of obesity among women who are overweight at diagnosis.<\/jats:p>","DOI":"10.3390\/curroncol29060326","type":"journal-article","created":{"date-parts":[[2022,6,6]],"date-time":"2022-06-06T10:08:24Z","timestamp":1654510104000},"page":"4090-4103","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Weight Gain after Hormone Receptor-Positive Breast Cancer"],"prefix":"10.3390","volume":"29","author":[{"given":"Archita","family":"Goyal","sequence":"first","affiliation":[{"name":"Department of Pathology, Johns Hopkins University, Baltimore, MD 21218, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabrielle E.","family":"Milner","sequence":"additional","affiliation":[{"name":"Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashley","family":"Cimino-Mathews","sequence":"additional","affiliation":[{"name":"Department of Pathology, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kala","family":"Visvanathan","sequence":"additional","affiliation":[{"name":"Department of Oncology, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio C.","family":"Wolff","sequence":"additional","affiliation":[{"name":"Department of Oncology, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dipali","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Oncology, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4513-4235","authenticated-orcid":false,"given":"Jennifer Y.","family":"Sheng","sequence":"additional","affiliation":[{"name":"Department of Oncology, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"394","DOI":"10.3322\/caac.21492","article-title":"Global cancer statistics 2018: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"68","author":"Bray","year":"2018","journal-title":"CA Cancer J.
