1. Abstract
1.1. Purpose: To explore the clinical outcomes of psychological intervention in the treatment of cancer pain caused by metastatic bone tumors.
1.2. Method: 60 patients with cancer pain caused by bone metastases in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, Chongming Branch, from January 2014 to December 2018 were enrolled in this study. All the patients were randomly divided into a control group and a test (PI) group (n = 30 in each group). In addition to the routine supportive treatment based on the patient's condition, stage, and clinical symptoms, the PI group was treated with psychological intervention measures
compared with the control group.
1.3. Results: The effective days of pain control of the patients in the PI group were more than those in the control group (63.4±14.99 days & 46.8±15.1 days, t=4.27, P <0.0001). In thefirst three months of treatment, the anxiety scores of PI group were significantly lower than the control group (P < 0.0001). The life quality scores for the PI were higher than that in the control groups (P <0.0001). 4) During the 90-day follow-up period, the survival days of the PI group were remarkably higher than that of control group (P<0.05).
