Try this:

        _Application app = new Application();
        try
        {
            _Document doc = app.Documents.Open("c:\\xxxx\\doc.doc");
            try
            {
                Range delRange = doc.Range();
                delRange.Start = doc.Bookmarks.get_Item("HTML_SECTION_START").Range.End;
                delRange.End = delRange.Bookmarks.get_Item("HTML_SECTION_END").Range.Start;
                delRange.Delete();
                doc.Save();
            }
            finally
            {
                doc.Close();
            }
        }
        finally
        {
            app.Quit();
        }

You can protect the Bookmark get_Item with Bookmark.Exists

Edit: You should save and close the document and the application
