Abstract

The clinical significance of B7‐H3 expression in gastric cancer remains unclear, although the B7 ligand family plays a critical role in the T cell‐mediated immune response. We therefore investigated B7‐H3 expression as a blood marker of circulating tumor cells and determined correlations with tumor progression in patients with gastric cancer. B7‐H3 expression in gastric cell lines was initially evaluated by immunocytochemistry. Furthermore, we used quantitative RT‐PCR to assess B7‐H3 mRNA expression in four cell lines and in 95 blood specimens from patients with gastric cancer, as well as in 21 samples of peripheral blood lymphocytes from healthy volunteers. B7‐H3 expression in cell lines was identified by immunocytochemistry and quantitative RT‐PCR. Blood specimens from patients with gastric cancer contained significantly more copies of B7‐H3 mRNA than those from healthy volunteers without cancer (P < 0.0001). Levels of B7‐H3 expression significantly correlated with overall stage (P = 0.013). The 5‐year survival rate was significantly lower in patients with high B7‐H3 expression than with low expression (P = 0.02). Multivariate analysis demonstrated that B7‐H3 expression was an independent prognostic factor (P = 0.046). Our results indicate that B7‐H3 appears to be a useful blood marker for predicting tumor progression in gastric cancer. (Cancer Sci 2011; 102: 1019–1024)

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.
