TP53 gene and pathway alterations in gastric-type adenocarcinoma of the cervix.
Article in JNCI cancer spectrum, 2025. 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
backgroundHuman papillomavirus infection contributes to the development of almost all cervical malignancies, aside from gastric-type adenocarcinoma of the cervix, a rare aggressive subtype without human papillomavirus infection.
methodsTo address the carcinogenic mechanism of this disease, we performed a comparative multi-omics analysis of gastric-type adenocarcinoma of the cervix and usual-type endocervical adenocarcinoma in 3 independent cohorts of patients with gastric-type adenocarcinoma of the cervix and usual-type endocervical adenocarcinoma. The first cohort comprised 8 gastric-type adenocarcinoma of the cervix and 22 patients with usual-type endocervical adenocarcinoma treated at the National Cancer Center Hospital between 2002 and 2020, who were examined by targeted and whole transcriptome sequencing. The other 2 cohorts comprised 52 patients with gastric-type adenocarcinoma of the cervix and 109 patients with usual-type endocervical adenocarcinoma and 39 patients with gastric-type adenocarcinoma of the cervix and 232 patients with usual-type endocervical adenocarcinoma, whose mutational data were obtained from the Center for Cancer Genomics and Advanced Therapeutics (Japanese patients) and Genomics Evidence Neoplasia Information Exchange (US patients) public databases, respectively. Metabolomic analysis was performed in 8 patients, including 5 with gastric-type adenocarcinoma of the cervix.
resultsTP53 mutations were more prevalent in gastric-type adenocarcinoma of the cervix than in usual-type endocervical adenocarcinoma in all 3 cohorts. Transcriptome analysis consistently revealed frequent suppression of TP53-related pathways in gastric-type adenocarcinoma of the cervix. Metabolites preferentially detected in gastric-type adenocarcinoma of the cervix tissues suggest TP53 alterations are implicated in intratumoral metabolic properties.
conclusionThe development of gastric-type adenocarcinoma of the cervix is likely driven by TP53 mutations, which play a large role in shaping intracellular signaling and metabolic profiles within tumor cells.
