PRIMARY outcome

Timeframe: Baseline and after surgery (seven to 28 days after baseline)

Population: Sixteen subjects received ATB, however, one subject had only one dose and was removed for analysis. The control group consisted of seven subjects who received placebos and seven matched controls.

This measure is the immunohistochemical evaluation using the antihuman Ki-67 monoclonal antibody MIB-1 and reporting the percentage of positively stained malignant cells.
