In Reply: Although Drs Schwarz and
Ellenhorn report excellent results from the City of Hope, they may have
misunderstood our definition of volume, which represents the total
number of procedures with the designated International
Classification of Diseases, Ninth Revision codes in the 10-year
period of the study that were performed in elderly patients. If the
relative frequencies of the types of procedure and age groupings in
their census of 50 cancer pancreatectomies are similar to what we
observed in the SEER-Medicare database, then City of Hope would be
classified as a high-volume center.
