State Health Registry releases Cancer in Iowa: 2001
IOWA CITY, Iowa -- An estimated 6,200 Iowans will
die from cancer this year and nearly 14,300 additional people in the state
will be diagnosed with the disease, according to "Cancer in Iowa: 2001," the
annual report issued by the State Health Registry of Iowa, based at the University
of Iowa College of Public Health. These projections are similar to those made
in prior years.
The report found that the top three cancer sites for
male and female adult cancers remain unchanged, said Charles F. Lynch, M.D.,
Ph.D., UI professor of epidemiology and medical director of the Iowa Cancer
For adult women, breast cancer remains the most common
cancer, followed by cancer of the colon and rectum, and lung cancer. Collectively,
the three cancers will account for more than half of all new cancers diagnosed
in Iowa women this year.
Prostate, lung, and colon and rectum cancers will
account for 60 percent of cancers found in men. Prostate cancer will continue
to be the leading type of new cancer in men, with 1,900 new cases expected
to be diagnosed among Iowa men in 2001.
Lung cancer will again cause the most deaths in both
men and women with cancer. Nearly 1,670 Iowans will die of lung cancer this
The report also includes a special section on childhood
cancers, finding dramatic increases since 1975 in survival rates for certain
cancers affecting those less than 20 years old.
"Over the past 26 years cancer incidence has increased
in adults but they have slightly better survival rates," Lynch said. "Over
the same period, while newly diagnosed childhood cancers have also increased,
mortality from them has appreciably declined."
From 1973-75, compared to 1996-98, cancer incidence
for males age 19 or younger increased from 14.1 per 100,000 population to
17.8 per 100,000 population, an increase of 26 percent. Incidence rates for
female children over the two same periods were slightly less, 11.9 per 100,000
population (1973-75) and 16.3 per 100,000 population (1996-98), but represented
an increase of 37 percent. Over the same periods, childhood cancer deaths
declined by nearly half -- about 56 percent for males and 48 percent for females.
Childhood cancers account for about one in every 100
cancers in Iowa. From 1973 through 1998, malignant cancers were newly diagnosed
in 3,551 Iowans under the age of 20. During the same period, a total of 330,274
Iowans were diagnosed with cancer.
Lynch noted that while childhood cancers rightly are
the cause of great concern, people often think childhood cancer is more common
than it really is.
Several different types of cancer comprise pediatric
tumors and their frequencies vary with age. The single most common type in
both male and female children is acute lymphocytic leukemia and is most often
seen in children ages 2 to 5.
"We don't know a lot about the risk factors for acute
lymphocytic leukemia, but we know that radiation exposure is a risk," Lynch
said. He added that rates of acute lymphocytic leukemia are higher in males
than in females and occur at about twice the rate in whites compared with
Astrocytoma, a type of brain cancer, is the second
most common type of malignant cancer in Iowa children, based on the 26-year
Hodgkin's disease, generally seen in children between
ages 15 and 19, is the third leading type of childhood cancers. This disease
arises in lymph nodes.

The State Health Registry has been gathering cancer
incidence and follow-up data for the state since 1973 and includes projected
numbers of new cancer diagnoses and cancer deaths for each county. The registry
is one of 10 registries nationwide that provide data to the National Cancer
