Efficacy of transcatheter arterial chemoembolization combined with sorafenib in inhibiting tumor angiogenesis in a rabbit VX2 liver cancer model.

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 aim of this study was to investigate the effects of transcatheter arterial chemoembolization (TACE) combined with sorafenib on tumor angiogenesis. MATERIALS AND
methodsThirty New Zealand rabbit VX2 liver cancer model animals were divided into five groups, which received either normal saline (A), TACE (B), sorafenib (C), sorafenib followed by TACE (D), or TACE followed by sorafenib (E). Serum vascular endothelial growth factor (VEGF) levels were measured before and after TACE via ELISA. Immunohistochemistry for CD34 was performed to evaluate microvessel density (MVD), and ultrasonography was used to access tumor volume.
resultsVEGF levels declined in group C but increased significantly on the 3rd post-operative day in groups B, D, and E. Levels decreased after the 7th post-operative day. Peak levels were significantly lower in group D than in groups B and E. On the 14th post-operative day, VEGF levels were the lowest in group C, followed by those in groups D and B. MVD was the lowest in group C followed by that in group D and E, and was the highest in group B. Group D had the smallest tumor volume. HE staining of tumor tissues from group C showed apoptosis in a scattered patchy pattern, whereas in groups B, D, and E, large areas of tumor cell necrosis were visible.
conclusionTACE can up-regulate serum VEGF levels, which in turn accelerates the formation of new blood vessels. Thus, TACE combined with sorafenib inhibits VEGF and angiogenesis, and pre-operative administration of sorafenib has a more superior anti-angiogenic effect than post-operative administration.
