Outcome Measures
Primary Outcomes (1)
Prevalence of high TF expression
Estimated in the analytic population as the number of samples in the population in which such expression is noted divided by 33. An assessment of the precision of such estimates will be provided by an exact binomial confidence interval. Comparison of normalized TF expression in non-metastatic versus metastatic patients will be done using the two-sample t-test.
1 month
Study Arms (1)
Observational
Tissue samples are analyzed for tumor factor expression levels by immunohistochemistry.
Interventions
