Prognostic factors and overall survival among patients with ovarian cancer in the pre-PARP inhibitor era: the OCRWE-Finland study.
Observational study in Acta oncologica (Stockholm, Sweden), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDespite recent treatment advances in ovarian cancer (OC), more real-world evidence studies investigating patient outcomes are needed. OCRWE-Finland was an observational cohort study investigating OC outcomes in Finland during the pre-PARP inhibitor era. PATIENTS: Patients were diagnosed with OC between 2014 and 2019 in Finland. This analysis reports baseline characteristics of all patients, patients with high-grade serous OC (HGSOC), and overall survival (OS) for patients with HGSOC.
resultsAmong 1,711 patients diagnosed with OC, 867 (51%) had HGSOC. The absence versus presence of visible residual disease post-debulking surgery was associated with improved OS for patients at stage III (n = 303; median: NR vs. 43 months; p = 0.005), but not stage IV (n = 118; median: 37 months vs. 40 months; p = 0.96). Bevacizumab treatment at any line at stages III/IV improved OS in the short-term only. Receiving versus not receiving bevacizumab at first-line for patients with visible residual disease post-debulking surgery was associated with improved OS at stage III (median: 48 months vs. 36 months; p = 0.003), but not stage IV (median: 42 months vs. 37 months; p = 0.26). Multivariate Cox regression analyses showed that stage IV at initial diagnosis and the presence of R2 classification post-debulking surgery resulted in poorer OS.
interpretationIn the pre-PARP inhibitor era, the absence versus presence of visible residual disease post-debulking surgery was associated with improved OS in stage III, but not stage IV HGSOC. First-line bevacizumab seemed to be beneficial in patients with stage III HGSOC and visible residual disease.
