1 · What the graph read from it

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.

2 · The registry

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

Metastasis remains the primary cause of mortality in pancreatic ductal adenocarcinoma (PDAC). Circulating tumor cells (CTCs) are key players in metastasis, yet the mechanisms governing CTCs formation and survival are incompletely understood. Here, we identify ITGA3 as a key driver of CTCs generation and metastatic progression in PDAC. Integrated proteomic and transcriptomic analyses, coupled with clinical specimen validation, revealed that ITGA3 expression positively correlates with CTCs abundance and poor prognosis. Mechanistically, ITGA3 promotes epithelial-mesenchymal transition (EMT), enhances matrix metalloproteinase expression, and facilitates tumor cell detachment, thereby initiating CTCs formation. Importantly, cancer-associated fibroblasts (CAFs) secrete laminin-332 (LAM332), which engages ITGA3 on PDAC cells to promote proliferation and invasion, drive homotypic CTC clustering, and suppress apoptosis, collectively sustaining CTCs' survival. Neutralization of CAFs-derived LAM332 impaired tumor cell proliferation and invasion, disrupted CTC cluster formation, increased apoptosis, reduced hepatic and pulmonary metastasis, and prolonged survival in mouse models. These findings uncover a CAFs-LAM332-ITGA3 axis that orchestrates CTCs formation and survival, and highlight this stromal-tumor interaction as a promising therapeutic target to mitigate metastatic progression in PDAC.
