Abstract: Objective To investigate the compliance of cancer pain treatment in tumor patients and its influencing factors. Methods Patients who received cancer pain treatment in a Hospital of Chengdu from January to October 2019 were selected to investigate their compliance status, and the influencing factors were analyzed by univariate and multivariate analysis methods. Results Among the 195 patients, there were 122 males and 73 females, with an average age of （63.10±11.72） years. The score of compliance of cancer pain treatment was （0.91±1.40）, and there were 120 patients with good compliance （61.5%）. The results of binary logistic regression analysis showed that the settlement method at one's own expense （OR=0.486）, the longer the course of the tumor （OR=0.561）, and no complications （OR=2.395） were the influencing factors for the compliance of tumor patients with cancer pain treatment. Conclusion The compliance of cancer pain treatment in tumor patients needs to be improved. Medical staff should pay more attention to the influencing factors of compliance and take targeted measures to improve the compliance of patients.
