Figure 1 Disease classification and organ donation status of patients who agreed to discontinue life-sustaining treatment (LST). Regarding the decision to discontinue LST, 175 (39.6%) and 267 (60.4%) were suitable and unsuitable for organ donation, respectively. Eighty-six of 175 patients were diagnosed with CNS disease, and only 17 (19.8%) agreed to donate after brain death (DBD), whereas 69 (80.2%) were eligible for DBD, but did not agree to donate. In contrast, although 2 patients with no recurrence or metastasis for >5 years and 87 patients with non-malignancy or non-CNS disease were eligible for organ donation, organ donation was not discussed with them because it is illegal under the current law in South Korea.
