Genetic Characterization of Ovarian Tumor Tissues from Patients with Epithelial Ovarian Cancer in a Philippine Tertiary Hospital: A Descriptive Study.
Article in Asian Pacific journal of cancer prevention : APJCP, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
objectiveThis study identified genetic variations in ovarian tumor specimens from Filipino epithelial ovarian cancer (EOC) patients using next-generation sequencing.
methodsGenomic DNA was isolated from formalin-fixed paraffin-embedded ovarian specimens from 8 chemosensitive and 8 chemoresistant EOC patients. Targeted next-generation sequencing was done to identify mutations in hotspot regions of common oncogenes and tumor-suppressor genes. The mutations were cross-referenced with dbSNP and ClinVar databases to identify previously reported alterations, and potentially damaging variants were predicted using PolyPhen-2.
resultsOur study has identified 85 unique variants, 35 in chemosensitive EOC, 22 in chemoresistant EOC, and 28 in both. Chemosensitive EOC specimens had more exonic single nucleotide variants than chemoresistant EOC specimens. Of the 50 oncogenes and tumor suppressor genes, KDR gene had the most frequent variations in EOC patients. Two of the unique KDR variants identified were novel mutations. Thirty-nine unique protein-modifying genetic variants were identified in all specimens, the majority of which have been previously reported in dbSNP and ClinVar.
conclusionThis study was the first non-BRCA genetic analysis done on ovarian cancer in Filipino patients. Next-generation sequencing was able to identify previously reported alterations with known therapeutic implications which may benefit from targeted therapy instead of standard chemotherapy regimen.
