The Cellular Basis of Site-Specific Tumor Metastasis

Flier, Jeffrey S., Underhill, Lisa H., Zetter, Bruce R.·1990·New England Journal of Medicine

Abstract

THE year 1989 marked the 100th anniversary of the publication of a seminal paper in the study of the biology of human tumors. Stephen Paget, having collected the autopsy records of 735 patients who died of breast cancer, noted that the majority of the metastatic lesions were found in the liver and brain, whereas other organs, such as the kidney and spleen, were much less frequently involved. Paget inferred from this observation that certain tumors were predisposed to spread to particular tissues, on the basis of the tissue's ability to support the growth of these tumors.1 He likened this process . . .

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
