Enumeration, classification and clinical application of circulating tumor cells in advanced gallbladder adenocarcinoma.
Article in BMC cancer, 2025. 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
backgroundThe relationship between circulating tumor cells (CTCs) and patients with advanced gallbladder adenocarcinoma (aGA) has been rarely studied. This article was to demonstrate the enumeration, classification, and clinical application of CTCs in patients with aGA. MATERIALS AND
methodsPeripheral blood samples were collected and CTCs were detected using the CanPatrol
resultsCTCs were detected at pre-treatment in 75.00% (27/36) of the patients. Both CTCs positive rate and CTCs enumeration at pre-treatment were significantly associated with clinicopathological parameters including Ca199 level (P = 0.014, P < 0.001 respectively), tumor differentiation (P = 0.007, P = 0.002 respectively), lymph infiltration (P = 0.010, P = 0.025 respectively), vascular infiltration (P = 0.007, P < 0.001 respectively), and distant metastasis (P = 0.015, P = 0.002 respectively). CTCs-positive patients had a significantly shorter OS (HR 0.335, 95% CI 0.165-0.678, P = 0.0023) and PFS (HR 0.364, 95% CI 0.179-0.739, P = 0.0024) than CTCs-negative patients. Mesenchymal CTCs enumeration was closely related to the chemotherapy response, and CTCs programmed cell death ligand-1 (PD-L1) was highly correlated with the immunotherapy response. Positive CTCs at pre-treatment was closely related to the poor OS (HR 0.089, 95% CI 0.020-0.399, P = 0.002) as well as distant metastasis (HR 0.159, 95% CI 0.041-0.610, P = 0.007), untreated with chemotherapy (HR 4.510, 95% CI 1.403-14.499, P = 0.011) and untreated with immunotherapy (HR 6.845, 95% CI 1.894-24.738, P = 0.003).
conclusionPretreatment-positive CTCs was closely related to the poor prognosis in patients with aGA. Monitoring the subtype and phenotype of CTCs may be one of the means to assess tumor treatment response.
