Olaparib monotherapy or combination therapy in lung cancer: an updated systematic review and meta- analysis.
Synthesis in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Background and aims: Impaired double strand DNA repair by homologous repair deficiency (HRD) leads to sensitivity to poly ADP ribose polymerase (PARP) inhibition. A subset of non-small cell lung cancers (NSCLCs) harbour impaired DNA double strand break repair. This study aims to investigate meta-analysis on the olaparib monotherapy or combination therapy in lung cancer. Methods: A comprehensive search was conducted in Pubmed, Scopus and Google Scholar data bases up to August 13, 2023 related articles were extracted title, abstract and full text of articles were screened. The quality included articles were assessing the data was extracted and hence analysis. Results: After screening 5208 articles, 9 were selected for final review based on relevance to the topic. Olaparib monotherapy increased progression free survival (PFS) level [ES= 7.76; 95% CI= 0.16 to 1.36; P=0.208]. Olaparib maintenance therapy increased PFS compared to placebo in platinum-sensitive NSCLC patients [ES= 0.9; 95% CI= 0.9 to 0.9]. Combination therapy with durvalumab and olaparib decreased PFS level compared to the olaparib group [ES=6.07; 95% confidence interval (95% CI) = 0.67 to 11.46; P=0.000]. Adding gefitinib to olaparib decreased PFS compared to olaparib only group, significantly (ES=3.39; 95% CI=-0.78 to 7.56; P=0.609). Conclusions: Our study demonstrated olaparib as monotherapy can increase the PFS of patients with lung cancer, but the combination of olaparib and gefitinib or the combination of olaparib plus durvalumab couldn't have a significant effect. According to the high heterogeneous rate of studies further large-scale randomized control trials are still required to progress association.
