Summary
Brief summary (as posted)
Breast cancer is the most common malignancy in women worldwide according to International Agency for Research on Cancer. Unfortunately, cancer survivors often face long-term symptoms that occur or persist after completion of treatment. In addition to fatigue, pain is the most common persistent symptom after cancer and cancer treatment. The diagnosis and treatment of pain in cancer survivors is not clear for many physicians. A mechanism-based classification of pain in cancer survivors might be a critical step for clinical reasoning, especially for discrimination of different pain types. The primary aim of this study is to determine the prevalence of the predominant type of pain in Turkish breast cancer survivors using a recent published clinical algorithm.

[]Primary outcomes (4)
- measure
- Numeric Pain Rating Scale
- timeFrame
- 1 minute
- description
- The NPRS was used to assess the participants' pain levels. In the NPRS, patients are asked to verbally rate the severity of their pain on a scale. The scale is composed of 0 (no pain at all) to 10 (worst imaginable pain).
- measure
- Margolis Pain Diagram
- timeFrame
- 5 minute
- description
- The Margolis Pain Diagram, consists of a dorsal and a ventral drawing body, is used to assess the location and distribution of the pain. Participants will ask to point out the place where they experience pain during the preceding 4 weeks for at least 24 hours
- measure
- Central Sensitization Inventory
- timeFrame
- 10 minute
- description
- The Central Sensitization Inventory (CSI) aims to evaluate symptoms thought to be associated with nociplastic pain. The CSI consists 25 items exploring emotional and somatic disorders associated with CS. Each response is scored from 0 to 4, yielding a total score of 0 to 100. A score of 40 or higher on the CSI means the presence of nociplastic pain.
