Yes - you can access the LabelStatisticsLogic and you can calculate these values. (Note that in newer Slicer we suggest using Segment Statistics, which is similar).
class LabelStatisticsLogic(ScriptedLoadableModuleLogic):
"""Implement the logic to calculate label statistics.
Nodes are passed in as arguments.
Results are stored as 'statistics' instance variable.
Uses ScriptedLoadableModuleLogic base class, available at:
