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

Overall survival rates for pediatric high-grade sarcoma have improved greatly in the past few decades, but prevention and treatment of distant metastasis remain the most compelling problems facing these patients. Traditional preclinical mouse models have not proven adequate to study the biology and treatment of spontaneous distant sarcoma metastasis. To address this deficit, we developed an orthotopic implantation/amputation model in which patient-derived sarcoma xenografts are surgically implanted into mouse hindlimbs, allowed to grow, then subsequently amputated and the animals observed for development of metastases. NOD/SCID/IL-2Rγ-null mice were implanted with either histologically intact high grade sarcoma patient-derived xenografts or cell lines in the pretibial space and affected limbs were amputated after tumor growth. In contrast to subcutaneous flank tumors, we were able to consistently detect spontaneous distant spread of the tumors using our model. Metastases were seen in 27-90 % of animals, depending on the xenograft, and were repeatable and predictable. We also demonstrate the utility of this model for studying the biology of metastasis and present preliminary new insights suggesting the role of arginine metabolism and macrophage phenotype polarization in creating a tumor microenvironment that facilitates metastasis. Subcutaneous tumors express more arginase than inducible nitric oxide synthase and demonstrate significant macrophage infiltration, whereas orthotopic tumors express similar amounts of inducible nitric oxide synthase and arginase and have only a scant macrophage infiltrate. Thus, we present a model of spontaneous distant sarcoma metastasis that mimics the clinical situation and is amenable to studying the biology of the entire metastatic cascade.
