<p>Overall survival, measured from the date of randomization for surgery.<br /><br>Overall and progression free survival, measured from the start of Imatinib<br /><br>therapy, will also be reported for the two therapeutics arms; however, this<br /><br>analysis will be descriptive only.<br /><br>In the surgery arm, pathological response to Imatinib will be assessed; the<br /><br>rate of complete resection and the surgical morbididy will also be reported.<br /><br>Quality of life.</p><br>
