Kaplan‐Meier estimates of overall survival by timing of radiation. The cohort was divided into patients who did not receive RT (median overall survival [OS], 4.0 months; 95% confidence interval [CI], 1.5–16.3), those who received RT within 2 months prior to starting ImTx (median OS, 13.2 months; 95% CI, 10.8–21.2), and all others (median OS, 16.5 months; 95% CI, 10.2–29.4). Although radiation was associated with an increase in overall survival, this was not dependent upon the timing of radiation and ImTx (overall p = .009; for the two RT groups, p = .76).
