Efficacy and toxicity of PARP inhibitor in elderly patients with homologous recombination-deficient newly diagnosed advanced ovarian cancer: the role of dose modification.

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
objectiveTo investigate the impact of age on the progression-free survival (PFS) and dose modification, discontinuation and adverse events of poly (adenosine diphosphate-ribose) polymerase inhibitor (PARPi) maintenance therapy in homologous recombination-deficient (HRD) ovarian cancer patients.
methodsWe analyzed 324 patients with advanced stage III-IV epithelial ovarian cancer who had either BRCA mutation or HRD between July 2019 and November 2022. The primary objective was to evaluate the efficacy of PARPis by comparing PFS between patients who received PARPis and those who did not, specifically within 2 age groups: patients aged <60 years and those aged ≥60 years. The secondary objective included evaluating the rates of dose modification, discontinuation, and occurrence of treatment-emergent adverse events in patients who used PARPis.
resultsOf the 324 patients, 139 patients (42.9%) were diagnosed at ≥60 years. The use of PARPis resulted in a significant improvement in PFS in both age groups (hazard ratio [HR]=0.37; p<0.01) for patients aged <60 years (HR=0.41; p<0.01) for those aged ≥60 years. The multivariable Cox proportional hazards analysis revealed no significant difference in the PFS benefit between the 2 age groups (HR=0.95; 95% confidence interval [CI]=0.65-1.37; p=0.76). Dose modifications were more frequent in the elderly cohort (63.9% vs. 46.5%; p=0.04).
conclusionPARPis significantly improved PFS in elderly ovarian cancer patients with BRCA mutations and HRD, with a toxicity profile similar to that of younger patients. Elderly patients benefited from frequent dose modifications without any negative impact on PFS outcomes.
