Acute Pain Trajectories and Persistent Pain After Breast Cancer Surgery

Persistent pain after breast cancer surgery (PPBCS) is a significant clinical problem, affecting between 25 and 50% of patients. Several factors are associated with the development of PPBCS, including acute postoperative pain. The analysis of pain trajectories through mixed model modeling is an alternative to static pain measures, improving precision and providing information on the time course of pain resolution. Our aim was to investigate if the characteristics of pain trajectories during the first postoperative week are correlated with the persistence of pain 3 months after breast cancer surgery.

Treatment and study plan

Primary outcomes

  1. Presence of pain 3 months after surgery, assessed with the Brief Pain Inventory questionnaire. Yes/No

    Time frame: 3 months

Secondary outcomes

  1. Acute pain trajectories (7 days) after surgery

    Time frame: One postoperative week

    The pain trajectory is the vector of 7 verbal numerical pain scores (from 0 to 10) recorded in a pain diary over the first 7 postoperative days
