Efficacy of Aminocaproic Acid in Preventing Postoperative Hematoma in Breast Cancer Surgery: A Prospective Study.
Trial report in Journal of surgical oncology, 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
BACKGROUND AND
objectivesHemorrhage after oncologic breast surgery occurs in up to 11% of cases, remaining the leading cause of reoperation. Although antifibrinolytics are widely used in other surgical settings, their role in oncologic breast surgery is not well established. This study evaluated the efficacy and safety of aminocaproic acid (ACAc) in reducing postoperative hematoma following oncological mastectomies.
methodsA prospective randomized study was conducted between July 2020 and May 2022, including women ≥ 18 years old undergoing mastectomy. Patients were randomized into three groups: (A) topical application of 5 g of ACAc; (B) intravenous 2.5 g administered 30 min before incision; and (C) no treatment (control). Statistical tests included ANOVA, Chi-square, and multivariable regression.
resultsA total of 166 patients were enrolled. Postoperative hematoma occurred in 3.6% of patients in group A, 1.8% patients in group B, and 12.7% in the control. Multivariable logistic regression demonstrated a protective effect of intravenous ACAc compared with control (p = 0.021). No differences in reoperation rates were observed. No thromboembolic events nor hepatic or renal toxicity occurred. Hypertension was identified as an independent risk factor for postoperative hematoma.
conclusionsIntravenous ACAc reduces postoperative hematoma in oncologic mastectomy and may represent a low-cost, effective adjunct to bleeding prevention in this setting.
