Chronic pain in breast cancer patients post mastectomy with alloplastic reconstruction: A scoping review
Bibliographic record
Abstract
INTRODUCTION: Women diagnosed with breast cancer are receiving mastectomy with implant-based reconstruction at an increasing rate. Chronic post-surgical pain can be a major concern for these patients. This review sought to address the knowledge gap on the prevalence, severity and characteristics of chronic pain in this population. METHODS: A scoping review was conducted using the Arksey and O'Malley framework. Five databases were searched using keywords. Two independent reviewers performed selection and data extraction of studies that met inclusion criteria. RESULTS: Seventeen studies were included in this review. Ten studies reported prevalence of chronic pain which ranged from 7.3%-90.9% with pooled prevalence of 26.3%. Nine studies reported severity of chronic pain using various scales and methodology; most patients' pain was not severe. Risk factors for chronic pain included axillary dissection, lack of perioperative local anaesthetic, younger age and use of a tissue expander. No studies reported on possible correlation between ethnicity and pain. Eleven different assessment tools were used to measure pain. CONCLUSION: Chronic pain following post-mastectomy implant-based breast reconstruction is prevalent, associated with specific risk factors and poorly characterised. There is a need to investigate and evaluate chronic pain in this population using validated breast cancer specific pain assessment tools.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
