Objective: Association between physical symptoms and psychosocial difficulties of cancer patients has been reported widely. Nevertheless, the effects of pain and other symptom control on anxiety in such patients have not been investigated well. We investigated the association of improvement of pain and other symptoms with patient anxiety, and assessed factors associated with improvement of such symptoms. Methods: Data of patients with advanced cancer admitted to a palliative care unit during August 2018 - June 2022 were analyzed retrospectively. Severity of pain, other symptoms, and anxiety was assessed by the Support Team Assessment Schedule Japanese version (STAS-J) administered at admission and after 2 weeks. Patients' physical data, their Palliative Prognostic Index (PPI) at admission, and their overall survival were collected and recorded. Results: Data of 701 patients were analyzed. Improvement of pain or other symptoms after 2 weeks was not associated with the PPI total score or actual survival (P = .105 and .999). Patients with higher anxiety on admission experienced improvement of pain or other symptoms more frequently (P = .005). Worsening of anxiety was observed less in patients who experienced improvement in pain or other symptoms after 2 weeks (P = .027). Conclusion: Pain or other symptoms of patients with advanced cancer was improved irrespective of the general condition indicated with actual survival and prognosis-predictive factors. These findings suggest the importance of pain and other symptoms' improvement and its important roles in the management of patient psychosocial problems such as anxiety.
