Abstract

Purpose The aim of this study was to evaluate the significance of RACK1 in predicting outcome for patients with oral squamous cell carcinoma (OSCC) compared with Ki67.Methods The expression of both RACK1 and Ki67 in 130 patients with OSCC was illustrated by using immunohistochemistry assay. Multiple logistic regression and Pearson's correlation coefficient were used. Recurrence versus non-recurrence of the malignant lesions was considered as the surrogate for clinical outcome of patients.Results Multivariable logistic regression showed that the elevated RACK1 immunostaining was a factor having great influence on OSCC prognosis. RACK1 staining was strongly related to that of Ki67. The area under the receiver operating characteristic curve for both biomarkers in predicting recurrence was 0.72 and 0.70 respectively, indicating an excellent discrimination for RACK1 as well as for Ki67.Conclusions These data indicate that increased RACK1 expression is an important outcome predictor for OSCC compared with Ki67.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The in-house oral tissues were diagnosed as hyperkeratosis without dysplasia and their genetic profiles are closer to normal tissue than malignant tissue.

    “The four were taken from three patients with an average age of 50, which were all diagnosed as hyperkeratosis without dysplasia by pathologists, just showing an increase in cell number in the spinous layer and/or in the basal/parabasal cell layers without cellular atypia, and its genetic profiles would be much more closed to normal tissue than malignant tissue22–24.”
  • The in-house tissues came from a previous project that found no significant expression difference among common epithelial markers in past and other studies.

    “which from our previous project found no significant expression difference among the common epithelial markers in our past study and other previous study22–24.”

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.
