Factors influencing the treatment effect of cancer pain in patients with moderate and severe chronic pain / 中国肿瘤临床

ABSTRACT

Objective:This study aimed to analyze the factors affecting the outcome of cancer pain in patients with moderate and severe chronic cancer pain for clinical decision making. Methods: Data were collected from 426 cancer patients with moderate and severe chronic cancer pain, and the factors affecting pain treatment were analyzed. Results:A total of 85.6%of patients had good pain control in 3 days (NRS≤3). Multivariate logistic regression models showed that the pain of patients with bone metastases (P=0.026), breakthrough pain after stable pain control (P0.05). Opioid combination with NSAIDs contributed to easier pain control (P=0.024). Digestive system tumors, pain intensity, limb pain, neuropathic pain, use of transdermal fentanyl matrix patch, multiple metastases in stage-IV patients were suggested to be risk factors of pain control in univariate logistic regression models (P<0.05). Conclusion: Bone metastases, breakthrough pain after pain relief, and high dose of MEDD were independent risk factors. Opioid combination with NSAIDs was a protective factor of pain control.
