Clinical Trial Summary

Pre-existing pain and severe postoperative pain are predictors of persistent pain after surgery, but a complete understanding on the development of persistent pain is still lacking. The study aims to identify clinically relevant and genetic risk factors for persistent postsurgical pain that can be reliably distinguished statistically.


Clinical Trial Description

The study will focus on: (i) risk factors representing biopsychosocial processes that influence chronic pain, such as pain and psychological vulnerability; (ii) genetic factors relating to mechanistic pathways to persistent pain generation. Patients will be recruited from those undergoing breast cancer surgery at the mentioned site. Pain and anxiety assessment will be conducted via visual analogue scoring, mechanical temporal summation assessment and a series of questionnaires. After the surgery, all patients will be given appropriate analgesia, and the pain score and analgesia usage will be recorded. Phone survey will be conducted 4 and 6 months, respectively, after surgery to determine the outcomes. ;
