Prompt identification of UWL can lead to earlier diagnoses and interventions for cancer. This study investigates the frequency and timing of UWL documentation and diagnoses in a cohort of cancer patients with measured UWL and sought to understand how recognition of UWL is related to stage of disease at cancer diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective cohort of adult gastrointestinal and non\u2010small cell lung cancer patients with measured UWL was evaluated. Body weight histories were manually reviewed for UWL. Patients with intentional weight loss, weight loss related to fluid status or weight loss with unclear intention were excluded. Records were assessed for the use of UWL\u2010related International Classification of Diseases codes and documentation of UWL. ULW was considered missed if it was not documented or diagnosed by a healthcare provider. Associations between weight loss over time, documentation and\/or diagnosis of UWL and stage of disease at cancer diagnosis were investigated through repeated measures mixed models and univariate and multivariate tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In total, 374 patients (24%) met the definition of UWL with an average weight loss of 8.6%\u2009\u00b1\u20090.3%. UWL was missed in 161 (43%) patients with cancer cachexia. The odds of undetected UWL were greater in patients &lt;\u200965\u2009years old, with NSCLC, with obesity and who were White. In the 213 patients with recognized UWL, the documentation of UWL occurred approximately\u20097\u2009months after their initial weight loss. The magnitude of weight loss was associated with cancer stage at cancer diagnosis (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.0001). Patients who experienced \u2265\u20097.5% UWL pre\u2010cancer diagnosis had a median cancer stage of 3 whereas patients who experienced &lt;\u20097.5% UWL had a median cancer stage of 2 at cancer diagnosis (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.0001).
