As radiology increases its ability to detect disease at an earlier, more treatable stage, so grows the opportunity to partner in the outcomes analyses that have so far eluded the specialty.
As physicians and patients join in the metaphoric burning of
managed care in effigy, the obvious question persists: who's
minding the store?
The question occurred one Sunday evening in May during a report
on 60 Minutes in which two prostate cancer patients and a urologist
discussed the disease, the treatment alternatives, the
consequences, and the suggestion that the best treatment could be
no treatment at all. A companion report did the same for ductile
carcinoma in situ (DCIS) patients and its treatment alternatives.
The segment raised the possibility that we may be overtreating some
cancers, which echoes what I have been hearing for some time in the
grumblings of mammographers on the overtreatment both locally and
systemically of DCIS.
In "The Flip Side of Malpractice" (page 34), associate editor
Chris Wolski quotes Leonard Berlin, MD, on the subject: "The
trouble with ductile carcinoma in situ is that most never develop
into invasive cancer (nobody knows the exact figures), most will
never grow, most will never injure or kill a woman. Some do, but
it's probably no greater than 25%." The placement of this story
within a broader story on malpractice and mammography raises an
irony that will not be lost on radiologists: they are not sued for
finding cancers, however threatening or not. They are sued for not
finding them. Yet the overtreatment of nonthreatening cancers
represents a squandering of resources that will become even more
precious as the proverbial monkey in the python-otherwise known as
the Baby Boom generation-works its way through its years of
greatest consumption of health care services.
As key players in disease triage, radiologists are intimately
connected with this issue of overtreatment, particularly as the
technological tools they wield become increasingly refined, at both
the anatomical and the molecular levels. This point was underscored
during a recent public forum in Cleveland on whole-body scanning,
jointly sponsored by the Cleveland Clinic and the Society for
Computer Applications in Radiology. Abdominal imager Brian Herts,
MD, regaled the audience with comparison 3-D reconstructions of a
coffee pot that had been imaged by 4-slice and 16-slice
multidetector CTs, not to mention a series of remarkable 3-D images
of the vessels of the heart. In presenting both the pros and cons
of the highly charged whole-body scanning debate, Michael Modic,
MD, chairman of radiology at the Cleveland Clinic, suggested that a
key driver for the practice is the enhanced ability to find
diseases during their detectable preclinical phase, providing
researchers with the requisite information to develop what he
called the "natural history of a disease." This brings us full
circle to the original question: what is to be done with the
disease after it is found?
There is, it seems, an opportunity for radiologists to
collaborate with their brethren in oncology as well as other
specialties, to develop the clinical research, particularly in the
realm of cancer, that would finally produce the outcomes that have
long eluded radiology's attempts to gather them. Evidence-based
medicine is a viable, even necessary, alternative to managed
care.
