Adenomyosis as a prognostic factor in ovarian cancer: a retrospective study.
Article in Archives of gynecology and obstetrics, 2025. 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
backgroundAdenomyosis is a gynecological condition that frequently coexists with gynecological malignancies and has been shown to influence disease outcomes. However, its impact on ovarian cancer prognosis remains unclear. This study aimed to investigate the relationship between adenomyosis and clinicopathological and prognostic features in ovarian cancer patients.
methodsWe retrospectively analyzed 226 patients with ovarian cancer who underwent surgery between 2020 and 2023. The patients were divided into two groups based on the presence (n = 114) or absence (n = 112) of adenomyosis, confirmed by histopathological examination. Clinicopathological characteristics, including histological subtypes, disease-free survival (DFS), and overall survival (OS) were compared between the groups with a median follow-up of 36 months.
resultsPatients with adenomyosis demonstrated more favorable characteristics, including early stage disease (54.3% vs 39.2%, p = 0.048), lower-grade tumors (55.2% vs 31.2%, p = 0.049), and smaller tumor sizes (39.4% vs 26.7%, p = 0.043). Adenomyosis was significantly associated with endometrioid subtype (OR = 2.89, p = 0.043) and negatively associated with serous carcinoma (OR = 0.39, p = 0.034). Three-year DFS was significantly better in the adenomyosis group (79.2% vs 73.9%, p = 0.01), particularly in high-grade tumors (80% vs 58%, p < 0.05). No significant difference was observed in overall OS (73.3% vs 73.1%, p = 0.14), although high-grade tumors with adenomyosis showed improved OS (71% vs 57%, p < 0.05).
conclusionThe presence of adenomyosis in patients with ovarian cancer was associated with favorable clinicopathological features, particularly endometrioid histology and low-grade tumors, and improved survival in high-grade tumors. These findings suggest a potential biological interaction between adenomyosis and ovarian cancer that warrants further investigation for personalized treatment approaches.
