High prevalence of symptoms was found in all subgroups, with higher intensity in subgroups closer to death, indicating a need for prophylactic and proactive symptom management. Less concordance was found among symptom prevalence, intensity, and association with distress in subgroups further from death. Future studies should investigate longitudinal associations between symptoms with low intensity and high distress, and examine their clinical implications.
