Mitotic activity tends to be the most predictive piece of information and indications here are of intermediate to low grade multifocal disease. <br />There is a choice to monitor and remove masses as needed but if there is concern about a too conservative approach, the use of long-term chlorambucil at 4mg/m&sup2; every other day may help to control the disease. Regular monitoring of bloodwork is recommended.</p><div style="clear:both;"></div>
