Abstract

The impact of interstitial inflammatory cells, such as mast cells, and angiogenesis on the prognosis of cancer patients has been reported in many solid tumors, although there is disagreement about their role. We undertook a retrospective study with tissue samples from 65 patients with stage I and II non-small cell lung cancer to assess the clinical pathologic role and prognostic significance of mast cells. Mast cell phenotypes were identified by immunohistochemistry for tryptase and chymase. In addition, we identified microvessels using the endothelial marker CD34. Mast cell and microvessel density was quantified by assessing immunopositive cells in the intratumoral and peritumoral zones of tumor specimens. Both mast cell and microvessel density was higher in the peritumoral zone than the intratumoral zone (P <or= .05). A positive correlation between mast cell (tryptase-chymase phenotype) and microvessel densities was observed in the intratumoral zone (P <or= .05), supporting the involvement of mast cells in the angiogenic process. Regarding survival, a subset of stage I patients had a worse prognosis at five years when low mast cell (tryptase-chymase phenotype) density was found in the peritumoral zone (median survival in months [range]: 27 [1-60] versus 46 [1-60]). Multivariate Cox analysis indicated that this parameter may be an independent prognostic factor (P <or= .05) useful for selecting candidates for earlier treatment.

  • Inflammatory mast cells up-regulate angiogenesis during squamous epithelial carcinogenesis

    “For example, when inducing squamous epithelial carcinogenesis in these mice, neoplastic growth was attenuated in comparison to MCproficient littermates, mostly by a lower activation of the angiogenic vasculature and a failure of keratinocytes to reach hyperproliferative growth characteristics [32].”

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.
