The impact of cytoreductive surgery on outcomes in high tumor burden ovarian cancer after induction of PARP inhibitors.

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
objectiveIn advanced ovarian cancer, achieving R0 resection is a critical strategy for improving prognosis. However, even with R0 resection, the prognosis of patients with a high tumor burden remains poor. This study aimed to assess whether the introduction of poly(ADP-ribose) polymerase inhibitors (PARPi) has enhanced outcomes in such cases.
methodsWe retrospectively analyzed patients with International Federation of Gynecology and Obstetrics (FIGO) stage III-IV ovarian cancer treated between January 2015 and December 2021. Patients were classified into Group A (pre-PARPi introduction) and Group B (post-PARPi introduction). Complete macroscopic resection was defined as R0. Progression-free survival (PFS), stratified by the Aletti Surgical Complexity Score (Aletti_SCS), was the primary endpoint and was evaluated using Cox regression models.
resultsA total of 434 patients were included. In Group A, among those who achieved R0, the median PFS was 23.5 months for patients with high Aletti_SCS (95% confidence interval [CI]=14-30) and not reached for those with low Aletti_SCS (95% CI=30-not reached; adjusted hazard ratio [HR]=0.36, 95% CI=0.20-0.62). In Group B, the median PFS was not reached in both patients with high Aletti_SCS (95% CI=not reached-not reached) and low Aletti_SCS (95% CI=22-not reached; adjusted HR=4.98, 95% CI=1.14-21.78).
conclusionFollowing the introduction of PARPi, there was a trend toward improved PFS in patients with a higher Aletti_SCS who underwent R0 resection. These findings suggest that R0 resection may improve prognosis even in cases with a high tumor burden in the PARPi era.
