Cholecystokinin type 2 receptor in colorectal cancer: diagnostic and therapeutic target.
Article in Journal of cancer research and clinical oncology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introductionCholecystokinin type 2 receptor (CCK2R), which mediates the action of gastrin and cholecystokinin (CCK), has been demonstrated to promote the proliferation of colorectal cancer (CRC). A number of studies showed that CCK2R overexpressed in gastric cancer and pancreatic cancer but few in CRC. The correlation between CCK2R expression and clinicopathological characteristics is also not clear.
methodsThis study investigated CCK2R expression in a wide range of cell lines and clinical CRC samples, and explored expression pattern and prognostic value of CCK2R in relation to clinicopathological parameters. The location and expression levels of CCK2R were measured by immunocytochemical (ICC), qRT-PCR and Western blot. The druggability and antineoplastic effects of CCK2R as a therapeutic target were investigated using an anti-CCK2R targeting recombinant toxin named rCCK8PE38 by CCK-8 assay.
resultsCompared with paracarcinoma tissues, tumor samples showed overexpression of CCK2R (p = 0.028) including both CRC tissue and plasma samples, with plasma detection showing a significant indication for CCK2R evaluation. Aberrant expression correlated significantly with histological type (p = 0.032) and p53 status (p < 0.01), and patients with CCK2R overexpression had significantly lower disease-free survival. Application of rCCK8PE38 demonstrated the specificity and druggability of CCK2R as a therapeutic target, providing a strategy for clinical case screening of drugs targeting CCK2R.
conclusionThis study highlighted the aberrant expression and clinical correlation of CCK2R and reveals its diagnostic, prognostic and treatment value in CRC. We hypothesize that CCK2R serve as a target for the diagnosis and treatment of this cancer.
