Post-Mastectomy Pain Syndrome Clinical Evidence from a Cancer Pain Clinic, 2022-2025

120 women with refractory post-mastectomy pain syndrome (PMPS) were analyzed in a retrospective study from a tertiary cancer pain clinic. The data, authored by Morsi Khashan and updated in April 2026, includes patient-reported measures like the Brief Pain Inventory and Pain Catastrophizing Scale. Pain phenotypes were classified as nociceptive (40.8%), neuropathic (25.0%), or mixed (34.2%), with factors like multiple pain sources and radiotherapy-attributed pain associated with mixed pain.

Use Cases

• Training classification models to identify mixed pain phenotypes based on clinical assessment criteria.
• Analyzing associations between pain sources (like radiotherapy) and pain phenotypes using logistic regression.
• Studying the relationship between patient-reported outcomes (BPI, PCS scores) and pain classifications.

Strengths

• Includes data from 120 patients with detailed clinical assessments.
• Patient-reported outcomes (BPI, PCS) provide standardized measures of pain and catastrophizing.
• Analysis covers a specific time range from January 2022 to September 2025.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The observational design and model limitations are noted by the authors.
