Prognostic influence of small leucine-rich proteoglycans on serous ovarian cancer.
Article in Journal of cancer research and clinical 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
purposeOvarian cancer is one of the most lethal cancers in women worldwide. To be able to offer successful treatment and improve the prognosis, knowledge of factors influencing the tumor microenvironment is indispensable. In this context, the influence of the extracellular matrix on tumor progression is increasingly recognized. Of note, preclinical data in cell line and animal models have suggested that several members of the small leucine-rich proteoglycan (SLRP) family are mechanistically involved in the regulation of tumor progression. We hypothesized that dysregulation of SLRP expression may have a prognostic value in ovarian cancer.
methodsTo distinguish whether this expression is altered in the cells themselves or in the extracellular matrix, quantitative Real-Time PCR was performed on ovarian cancer cell lines and complemented by analysis of CCLE datasets. We used Kaplan-Meier survival curves to investigate whether a high or low mRNA expression influences the survival of ovarian cancer patients. Finally, the interactions of the SLRPs were investigated using a STRING analysis.
resultsWe demonstrated the potential beneficial effect of a low mRNA expression of most SLRPs on the prognosis of serous ovarian cancer. STRING analysis revealed interactions with other proteins already known to influence tumor behavior and metastasis of various carcinomas.
conclusionThese findings suggest that SLRPs may be involved in ovarian cancer biology and could represent candidates for further mechanistic investigation. However, their potential relevance for therapeutic strategies, including treatment response, requires additional functional validation.
