Effect of exercise based prehabilitation on postoperative pain in breast cancer patients: a systematic review with meta-analysis.
Synthesis in Breast cancer (Tokyo, Japan), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPostoperative pain is a common complication following breast cancer surgery, adversely influencing recovery and quality of life. Exercise-based prehabilitation, initiated before surgery to enhance physical readiness, has shown benefits in other surgical settings. However, its specific impact on postoperative pain in breast cancer patients remains unclear.
methodsThis systematic review and meta-analysis evaluated the effectiveness of exercise-based prehabilitation in reducing postoperative pain in women undergoing breast cancer surgery. Following PRISMA guidelines, a comprehensive search was conducted in PubMed, Scopus, and Web of Science up to June 2025 (search conducted prior to submission). Eligible studies were randomized controlled trials (RCTs) comparing exercise-based prehabilitation with usual care or educational interventions. The primary outcome was pain at one month post-surgery. Risk of bias was assessed using the Cochrane RoB 2 tool, and methodological quality via the TESTEX scale.
resultsSix RCTs (n = 519) were included in the qualitative synthesis, and three (n = 157) in the meta-analysis. Interventions varied in duration (1-9 weeks), modality (aerobic, resistance, mobility, stretching), and supervision. Pain was measured using tools such as VAS, NPRS, EORTC QLQ-C30 and SPADI. Meta-analysis showed a small, non-significant effect (SMD = -0.24; 95% CI: -0.55 to 0.08; p = 0.14). Heterogeneity was statistically low (I² = 0%; 95% CI: 0% to 79%), although this estimate was based on only three studies and should not be interpreted as evidence of true consistency across trials.
conclusionsExercise-based prehabilitation was reported as safe and feasible in the included studies, with a possible but non-significant benefit in reducing postoperative pain. Given the low certainty of evidence, further high-quality RCTs are needed to clarify its role in breast cancer surgical care.
