Chemotherapy-Related Toxicity and Preoperative Physiologic Reserve as Risk Markers for Complications After Immediate Breast Reconstruction.
Article in Journal of breast cancer, 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
purposeDespite advances in neoadjuvant chemotherapy (NACT) for breast cancer, surgical outcomes following immediate breast reconstruction (IBR) remain inconsistent, and institutional protocols vary widely. Although patients exhibit heterogeneous physiological responses to chemotherapy, few studies have evaluated treatment-related toxicity as an objective risk marker of postoperative complications. The aim of this study was to assess whether patient-specific responses to NACT can serve as clinically relevant markers of complication risk and guide individualized surgical planning.
methodsA retrospective analysis was conducted of 299 patients who underwent IBR, including 47 who underwent NACT. Chemotherapy-related toxicities and preoperative laboratory values were reviewed to determine the physiological burden. Postoperative complications and delays in the initiation of adjuvant therapy were assessed, and multivariate logistic regression was performed to identify independent factors associated with surgical morbidity.
resultsNACT and smoking were significantly associated with an increased risk of complications. NACT was also strongly associated with major wound complications. Patients with hematologic toxicity during NACT or preoperative hypoalbuminemia had substantially higher odds of developing major wound complications. In addition, NACT and diabetes were associated with delayed initiation of adjuvant therapy. NACT was not associated with minor wound complications, such as hematoma or seroma formation.
conclusionThis study suggests that treatment-related toxicity and preoperative physiological reserve may serve as clinically relevant, response-based markers for risk stratification after NACT. This approach provides a conceptual framework for future studies with larger sample sizes and well-controlled designs.
