Measure Description  Prediction efficacy is estimated using a hazard ratio (HR) and Cstatistic (Cstat). Progression free survival is defined as the span of time from day 1 of therapy to date of disease recurrence (measured in months). Results are pooled with subjects from a pilot RDRC study for a total of 27 subjects analyzed. FLT uptake in the tumor is a dynamic process that involves facilitated diffusion in and out of the cell and molecular changes in FLT. The rate, measured in mL/g/min, is a composite of the rate of transport of FLT from blood into the tissue and the transfer from tissue back into the blood, as well as the rate of molecular change of FLT.

The rate, measured in mL/g/min, is a composite of the rate of transport of FLT from blood into the tissue and the transfer from tissue back into the blood, as well as the rate of molecular change of FLT.

28. Primary:  Efficacy of Percent Change in Mean FLT Uptake (SUVmean) in Predicting Overall Survival (OS) [ Time Frame: 36 months ] 
Measure Type  Primary 

Measure Title  Efficacy of Percent Change in Mean FLT Uptake (SUVmean) in Predicting Overall Survival (OS) 
Measure Description  Prediction efficacy is estimated using a hazard ratio (HR) and Cstatistic (Cstat). Overall survival is defined as the span of time from day 1 of therapy to date of death from any cause (measured in months). Results are pooled with subjects from a pilot RDRC study for a total of 25 subjects analyzed. 
Time Frame  36 months 
Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
