For all patients, tumor grade affected overall survival (P =.006).
However, its ability to accurately identify tumor grade is limited.
No correlation between PIK3CA mutations was observed with tumor grade, histology or overall survival.
The factors of residual tumor grade and histologic regression grade also had good correlations with the prognosis (residual tumor grade, P =.0324; histologic regression grade, P <.0001).
Patient specific information pertaining to race, tumor grade, and outcome were not explicitly recorded for this study.
Pleural invasion and tumor grade were not significant in this multivariate model, after controlling for other variables.
and the expression of HIF-1α negatively correlates to ERα status and positively correlates to tumor grade.
This high Cox-2 pattern was retained in 44% of cancers, irrespective of tumor grade and stage.
The SI score outperformed tumor grade and pleural invasion in univariate (Table 2) and/or multivariate survival models (Table 3).
By contrast, epithelial tumor grade (which includes the assessment of keratinization) was not significantly associated with survival (Table 2).
HSCORE correlated with tumor grade for breast and endometrial carcinoma.
