Going the Distance
Cancer patients who travel more than 15 miles
for treatment have one-third the risk of dying than patients who
reside closer to their treatment centers. For every 10 miles a patient
travels, death risk decreases by 3.2 percent. That’s according
to a study led by Everett Vokes, chief of hematology and oncology
at the University of Chicago Hospitals.
Reported in the September 17 Journal
of the National Cancer Institute, the study controlled for
variables such as patients’ disease stage and economic status,
leaving distance as the only measured factor correlating with mortality
rates. Although the researchers found the result perplexing, Vokes
speculates that distance from the treatment center may be a useful
marker for some resources that cannot be assessed statistically,
including awareness of alternative health-care options, personality
traits such as compliance or motivation, or a supportive social
network. The results confirm a notion that oncologists “have
long appreciated,” Vokes says. Patients who explore therapeutic
options tend to “fare better than those who end up at the
closest place.”—J.N.L.
