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

Lymph node colonization by tumor cells is one of the key determinants of melanoma staging and prognosis, and tumor-associated macrophages (TAMs) are the predominant type of inflammatory cell in the tumor environment which secretes vascular endothelial growth factor (VEGF)-C, the most potent lymphangiogenic growth factor. In the present study, to elucidate the mechanism involved in VEGF-C expression in TAMs, murine peritoneal macrophages were co-cultivated with syngeneic B16 melanoma cells to mimic the reciprocal interactions between tumor cells and macrophages found in spontaneous tumors. In the present study, upon contact with tumor cells, macrophages were found to express a higher level of VEGF-C which was associated with an increase in the expression of IL-1β and TNF-α and their receptors. Antibodies against the IL-1β and TNF-α receptors were added to media that had been conditioned by the macrophage-tumor cell co-cultures and inhibition of VEGF-C was observed in macrophages co-cultivated with the tumor cells. Furthermore, when IL-1β and TNF-α were used at a non-toxic level, they enhanced peritoneal lymph node colonization by melanoma cells. Thus, in the present study, macrophagic IL-1β and TNF-α were observed to promote VEGF-C expression in TAMs, as well as melanoma lymph node metastasis, suggesting that inhibiting the signaling between tumor cells and TAMs may be required to inhibit lymphangiogenesis and lymph node metastasis.
