Heparanase (HPSE) genetic variants as prognostic indicators in ovarian cancer: evidence from discovery and validation cohorts.
Article in Molecular biology reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
backgroundHeparanase uniquely cleaves heparan sulfate, the main component of the outer layer of endothelial cell plasma membranes, promoting tumour invasion and dissemination. However, it can also enhance tumour immune surveillance and clearance. heparanase's versatility extends to pro-thrombotic properties, such as the promotion of tissue factor release. Interestingly, elevated heparanase levels have been found in ovarian cancer (OC), which has a notably high incidence of venous thrombosis. Previously, single-nucleotide polymorphisms (SNPs) of HPSE were shown to modulate mRNA and protein levels, possibly predicting disease outcomes. METHODS AND
resultsGiven the potential role of heparanase in OC, the implications of three SNPs - rs11099592, rs4364254 and rs4693608 - were investigated in OC patients. In the discovery cohort, rs11099592 TT genotype and rs4364254 C allele carriers showed lower survival time than their counterparts (log-rank test, p = 0.025 and p = 0.001, respectively). Validation cohort analysis confirmed the worse prognosis associated with the rs11099592 T allele and the rs4364254 C allele in non-serous (log-rank test, p = 0.016) and platinum-resistant (log-rank test, p = 0.044) OC patients, respectively. The rs4364254 C allele was associated with reduced HPSE expression in peripheral blood components (χ
conclusionsHPSE rs11099592 and rs4364254 showed prognostic value, with T and C allele carriers, respectively, displaying worse clinical outcomes. These results indicate that heparanase could enable a tumour microenvironment shift towards a less aggressive cancer behaviour, facilitating leukocyte migration and anti-tumour responses. Further research should explore the dual mechanisms of this protein to improve OC management.
