Ang-2 modulates VEGFR3-induced lymphangiogenesis in peritumoral adipose tissue of metastatic head and neck cancer.

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
Experimental studies have highlighted the connection between tumor-associated lymphatic vessel formation and adipose tissue. However, peritumoral lymphangiogenesis in metastatic head and neck cancer (HNC) remains insufficiently explored. This study contrasts lymphangiogenesis and regulatory factor expression in peritumoral adipose tissue (PTAT) surrounding metastatic head and neck tumors versus primary tumors. Histological, histochemical, and real-time PCR analyses were conducted on perioperatively collected adipose tissue samples from primary and metastatic tumors. Lymphatic Vessel Endothelial Hyaluronan Receptor-1 (LYVE-1) positive lymphatic vessel density significantly increased in peritumoral adipose tissue around metastatic tumors (M-PTAT). In M-PTAT, lymphatic vessels expressing LYVE-1 or VEGFD significantly increased, correlating with inflammatory cell count, elevated angiopoietin-2 (Ang-2) expression, and fibrosis factors. Expression levels of VEGF-D, VEGF receptor-3, and other lymphangiogenesis regulators in M-PTAT significantly surpassed those in peritumoral adipose tissue around primary tumors (P-PTAT). Notably, Ang-2 expression, confirmed histologically and at the mRNA level, was higher in M-PTAT than in P-PTAT. Ang-2 and VEGF-D stimulation promoted sprout formation in human lymphatic endothelial cells. This study underscores that M-PTAT, compared to primary tumors, exhibits more extensive lymphangiogenesis, inflammation, and fibrosis due to overexpression of Ang-2, LYVE-1, and VEGF-D.
