Yet, reduced dose intensity is a common method of mitigating the chemotherapy-induced side effects. Exercise has been shown to attenuate chemotherapy-related symptoms that frequently cluster together. Understanding this, we conducted a retrospective analysis in patients with advanced disease treated with adjuvant or neoadjuvant chemotherapy regimens and who completed exercise training during treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Data were collected retrospectively in a chart review of 184 patients, aged 18\u2009years or older and treated for Stage IIIA-IV cancer. Data collection included baseline patient demographics and clinical characteristics, including age at diagnosis, cancer stage at initial diagnosis, chemotherapy regimen, and planned dose and schedule. Cancer types included brain (6.5%), breast (35.9%), colorectal (8.7%), non-Hodgkin\u2019s lymphoma (7.6%), Hodgkin\u2019s lymphoma (11.4%), non-small cell lung (16.8%), ovarian (10.9%), and pancreatic (2.2%). All patients completed at least 12\u2009weeks of prescribed, individualized exercise. Each program included cardiovascular, resistance training, and flexibility components, under the supervision of a certified exercise oncology trainer once a week.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>RDI was measured for each myelosuppressive agent in a regimen over the entire chemotherapy course and then averaged across the myelosuppressive agents in a regimen. An RDI of less than 85% was designated as the clinically meaningful threshold for reduction in RDI based on previously published studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>A considerable proportion of patients across regimens had dose delays (18.3%-74.3%) and dose reductions (18.1%-84.6%). Between 12% and 83.9% of patients missed at least 1 dose of a myelosuppressive agent that was part of their standard regimen. Overall, 50.8% of patients received less than 85% of the RDI. In short, patients with advanced cancer and an exercise adherence above 84.3% saw fewer chemotherapy dose delays and dose reductions. These delays and reductions occurred significantly less frequently compared to the published norms in the sedentary population ( P\u2009&lt;\u2009.05).<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15347354231168368","type":"journal-article","created":{"date-parts":[[2023,4,20]],"date-time":"2023-04-20T02:44:50Z","timestamp":1681958690000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":29,"title":["Dose Delays, Dose Reductions, and Relative Total Dose Intensity in Patients With Advanced Cancer Who Exercised During Neoadjuvant Chemotherapy Treatment"],"prefix":"10.1177","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3233-4091","authenticated-orcid":false,"given":"Karen Y.","family":"Wonders","sequence":"first","affiliation":[{"name":"Wright State University, Dayton, OH, USA"},{"name":"Maple Tree Cancer Alliance, Dayton, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathryn","family":"Schmitz","sequence":"additional","affiliation":[{"name":"University of Pittsburgh Medical Center, Pittsburgh PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jay","family":"Harness","sequence":"additional","affiliation":[{"name":"Maple Tree Cancer Alliance, Dayton, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,4,19]]},"reference":[{"key":"bibr1-15347354231168368","doi-asserted-by":"publisher","DOI":"10.6004\/jnccn.2003.0038"},{"key":"bibr2-15347354231168368","doi-asserted-by":"publisher","DOI":"10.6004\/jnccn.2009.0009"},{"key":"bibr3-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1111\/appy.12055"},{"key":"bibr4-15347354231168368","volume":"371","author":"Hanna TP","year":"2020","journal-title":"BMJ"},{"key":"bibr5-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2019.03.244"},{"key":"bibr6-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0199532"},{"key":"bibr7-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1002\/cam4.2830"},{"key":"bibr8-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1002\/hed.24608"},{"key":"bibr9-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/j.critrevonc.2014.10.006"},{"key":"bibr10-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1002\/onco.13822"},{"key":"bibr11-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2003.05.002"},{"key":"bibr12-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2004.03.213"},{"key":"bibr13-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199504063321401"},{"key":"bibr14-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9343(80)90472-6"},{"key":"bibr15-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1186\/s12885-015-1104-5"},{"key":"bibr16-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/j.clbc.2018.02.003"},{"key":"bibr17-15347354231168368","first-page":"29","volume":"14","author":"Coldman AJ","year":"1987","journal-title":"Semin Oncol"},{"key":"bibr18-15347354231168368","volume":"24","author":"Norton L.","year":"1997","journal-title":"Semin Oncol"},{"key":"bibr19-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1177\/1534735419839466"},{"key":"bibr20-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/j.breast.2017.04.003"},{"key":"bibr21-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1111\/sms.12581"},{"key":"bibr22-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmrj.2017.07.074"},{"key":"bibr23-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbi.2019.08.187"},{"key":"bibr24-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/j.critrevonc.2017.11.002"},{"key":"bibr25-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1007\/s00520-017-4013-0"},{"key":"bibr26-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1007\/s00520-019-04680-w"},{"key":"bibr27-15347354231168368","doi-asserted-by":"publisher","DOI":"10.2147\/NSS.S18895"},{"key":"bibr28-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2011.07.028"},{"key":"bibr29-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.29383"},{"issue":"1","key":"bibr30-15347354231168368","first-page":"1","volume":"3","author":"Wonders KYK","year":"2018","journal-title":"J Adenocarcinoma Osteosarcoma"},{"key":"bibr31-15347354231168368","doi-asserted-by":"publisher","DOI":"10.1111\/bph.15141"},{"key":"bibr32-15347354231168368","unstructured":"Ettinger DS, Wood DE, Akerley W, et al.
