High cost of cancer care in the U.S. doesn't reduce mortality rates

While the U.S.
spends twice as much on cancer care as the average high-income country, its
cancer mortality rates are only slightly better than average, according to a
new analysis by researchers at Yale University and Vassar College.(Illustration by Michael S. Helfenbein)
The results
were published May 27 in JAMA Health Forum.
"There is
a common perception that the U.S. offers the most advanced cancer care in the
world," said lead author Ryan Chow, an M.D./Ph.D. student at Yale.
"Our system is touted for developing new treatments and getting them to
patients more quickly than other countries. We were curious whether the
substantial U.S. investment on cancer care is indeed associated with better
cancer outcomes."
Out of the 22
high-income countries included in the study, the United States had the highest
spending rate.
"The U.S. is spending over $200 billion per year on cancer care -- roughly $600 per person, in comparison to the average of $300 per person across other high-income countries," said senior author Cary Gross, professor of medicine and director of the National Clinician Scholars Program at Yale. "This raises the key question: Are we getting our money's worth?"
The researchers
found that national cancer care spending showed no relationship to
population-level cancer mortality rates. "In other words, countries that
spend more on cancer care do not necessarily have better cancer outcomes,"
said Chow.
In fact, six
countries -- Australia, Finland, Iceland, Japan, Korea, and Switzerland -- had
both lower cancer mortality and lower spending than the United States.
Smoking is the
strongest risk factor for cancer mortality, and smoking rates have historically
been lower in the United States, compared to other countries. When the
researchers controlled for international variations in smoking rates, U.S.
cancer mortality rates became no different than the average high-income
country, with nine countries -- Australia, Finland, Iceland, Japan, Korea,
Luxembourg, Norway, Spain, and Switzerland -- having lower smoking-adjusted
cancer mortality than the United States.
"Adjusting
for smoking shows the United States in an even less favorable light, because
the low smoking rates in the U.S. had been protective against cancer
mortality," said Chow.
More research
is needed to identify specific policy interventions that could meaningfully
reform the United States cancer care system, the authors say. However, they
point to lax regulation of cancer drug approvals and drug pricing as two key
factors contributing to the high cost of U.S. cancer care.
"The pattern of spending more and getting less is well-documented in the U.S. healthcare system; now we see it in cancer care, too," said co-author Elizabeth Bradley, president of Vassar College and professor of science, technology, and society. "Other countries and systems have much to teach the U.S. if we could be open to change."
