Gene expression of Nectin-4 and its clinical significance in dogs with primary lung adenocarcinoma.

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
backgroundCanine primary lung adenocarcinoma (CPLA) is suspected by radiography or computed tomography; however, since there are no tumour markers, early diagnosis is difficult, and the prognosis is poor due to increased tumour volume. Nectin-4 has been reported to be expressed in human lung, ovarian, and pancreatic cancers and promotes tumour growth. It has been reported to be a tumour marker and prognostic factor, and oncolytic virotherapy is being investigated using nectin-4 as a therapeutic target.
objectivesThe purpose of this study was to investigate the expression of Nectin-4 in CPLA and its clinical significance in dogs with pulmonary adenocarcinomas.
methodsThe relationships between Nectin-4 expression and signalling, tumour volume, tumour weight, and prognosis were analyzed in 34 CPLA patients.
resultsThe expression of canine Nectin-4 (high Nectin-4) was found in 25 of 34 cases (73%), and Nectin-4 expression levels did not show any significant associations with gender, body weight, and tumour stage. However, there was a significant positive correlation between Nectin-4 expression and tumour volume (r = 0.623, p < 0.05) and tumour weight (r = 0.735, p < 0.05). Regarding prognosis, the median survival time was 427 days in high Nectin-4 cases and 420 days in cases with no Nectin-4 expression.
conclusionOur study demonstrated that Nectin-4 is highly expressed in CPLA. In addition, nectin-4 might be a tumour growth factor in CPLA and thus is a promising biomarker for CPLA. Further investigations on nectin-4 in CPLA are warranted for its diagnosis and novel targets for oncolytic virotherapy.
