Comparison (Differences of Least Square Means) of study group from Column I to study group in Column II on a select day of the study. Comparison of study groups evaluates for statistically significant difference in total tumor volumes (p-value < 0.05, two tailed).

*

Groups as follows: A = Control; B = Docetaxel + Estramustine; C = Docetaxel; D = Targeted-Radiotherapy (TRT); E = TRT+ Docetaxel; F = TRT + Docetaxel + Estramustine.

**

Day refers to number of days post dose initiation (day 0).

***

Mean estimate ± SD (total tumor volume in cm3 per mouse). Standard error of statistical comparison of Column I and II is 0.020.
