Office Interop: Cancellation

Let's say I want to convert a PowerPoint file to a PDF file using Office Interop:

using Microsoft.Office.Core;
using Microsoft.Office.Interop.PowerPoint;

Application app = null;
try
{
    app = new Application();

    Presentation doc = app.Presentations.Open("Document.pptx", MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
    doc.SaveAs("Document.pdf", PpSaveAsFileType.ppSaveAsPDF, MsoTriState.msoFalse);
    doc.Close();
}
finally
{
    if (app != null)
        app.Quit();
    app = null;
}

How can I cancel that?

SaveAs may require an unreasonable amount of time to finish in case the document is sufficiently complex. So, the user may want to cancel.
