To the Editor: The May 2007 issue of Journal of Oncology Practice (JOP) contains two brief references to the use of nonphysician providers in oncology. Both deserve additional comment. Dr James Cohen, in his Letter to the Editor regarding the findings of the workforce study published in JOP in March, writes that the use of physician-extenders will be detrimental to the role of the physician-patient relationship.1 The growing body of data regarding the use of physician-extenders in the workforce suggests, in fact, that physician-extenders improve patient satisfaction, and professional satisfaction without adversely impacting the professional relationship between the patient and the physician.2 Dr Peter Paul Yu, writing for the ASCO Clinical Practice Committee discusses the potential role the nurse practitioner (NP) may play in the oncology workforce by examining what is currently understood about the background and training of the NP in oncology.3 Absent from the discussion is a similar consideration of requirements for physician assistant (PA) education. PA education is structured in the medical model. There are more than 130 accredited PA training programs. PAs must pass a national certifying examination in order to use the title Physician Assistant-Certified. Certified PAs must take a recertification examination every 6 years, in addition to earning 100 hours of continuing medical education credits every 2 years. Specialty certification is not required of PAs wishing to practice in subspecialties. There is currently one postgraduate residency program for PAs interested in additional oncology training. PAs work in the complete spectrum of oncology care, including medical oncology, surgical oncology, and radiation oncology, in the treatment of both pediatric and adult patients. To represent completely the spectrum of nonphysician providers in oncology care, PAs should be included in the ASCO Clinical Practice Committee discussion regarding nonphysician provider education and training.
