Self-reported pain using the numeric rating scale (0\u201310), documented within 30\u00a0days of chemotherapy initiation, was categorized as none (0), mild (1\u20134), moderate (5\u20137), or severe (8\u201310). Baseline demographics, opioid use, and frailty (measured using a deficit accumulation approach) were collected. Kaplan\u2013Meier was used to compare OS between groups. Cox proportional hazards models evaluated the association between pain levels and OS, adjusting for demographics, cancer stage and type, opioid use, and frailty.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 509 patients (median age 72.2\u00a0years; 55% female; 83.5% white; 13.4% Black), pain was highly prevalent: 16.5% reported mild, 19.6% moderate, and 17.3% severe pain. Median OS was significantly lower for patients with severe pain (9.1\u00a0months, 95% CI 6.5\u201312.7) compared to those with no pain (29.1\u00a0months, p\u2009&lt;\u20090.0001). Severe pain (HR 1.60, 95% CI 1.14\u20132.24) and moderate pain (HR 1.52, 95% CI 1.10\u20132.10) were independently associated with higher mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Self-reported pain was significantly associated with reduced OS in older adults with cancer.
