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

Small-cell lung cancer (SCLC) is an aggressive cancer with high metastatic ability and novel strategies against the metastasis are urgently needed to improve SCLC treatment. However, the mechanism of metastasis of SCLC remains largely to be elucidated. For further studies of SCLC metastasis, we developed a new orthotopic transplantation model in mice. We established a GFP-labeled subline from the human SCLC cell line DMS273 and transplanted them orthotopically into the lung of nude mice with Matrigel. The GFP-labeled cells showed significant metastatic activity and formed metastatic foci in distant tissues such as bone, kidney, and brain, as observed in SCLC patients. From a bone metastasis focus of the mouse, we isolated another subline, termed G3H, with enhanced metastatic potential and higher hepatocyte growth factor (HGF) expression than the parental line. Further studies indicated that the HGF/MET signaling pathway was involved in in vitro motility and invasion activities of the G3H cells and treatments with MET inhibitors decreased formation of distant metastases in our orthotopic model using G3H cells. These data indicated that our model mimics the clinical aspect of SCLC such as metastatic tropism and autocrine of HGF/MET signaling. Compared with other orthotopic SCLC models, our model has a superior ability to form distant metastases. Therefore, our model will provide a valuable tool for the study of SCLC metastasis.
