State Health Registry of Iowa releases its 1998 cancer report
IOWA CITY, Iowa -- Cancer is second only to heart disease as a leading
cause of death in Iowa and will claim the lives of an estimated 6,350 Iowans
in 1998. This information is provided in an annual report issued by the
State Health Registry of Iowa, based at the University of Iowa College
Cancer in Iowa: 1998 is the Registry's latest report on new cancer cases
and cancer deaths in Iowa. The report notes that an estimated 14,000 new
cancer cases will be diagnosed in the state this year. More than 80 percent
of these new cancers will occur in people age 55 and older.
"Applying Iowa's 1995 census population of 2.84 million people
means that about five of every 1,000 Iowans will be newly diagnosed with
some type of cancer this year," says
Dr. Charles Lynch, UI associate professor of preventive medicine and
environmental health and medical director of the Iowa Cancer Registry.
Breast cancer, followed by cancers of the colon and rectum, lung, and
uterus will be the most common new cancer cases diagnosed in women this
year. For men, prostate cancer will be most commonly identified in 1998,
followed by lung cancer, colorectal cancer and non-Hodgkin's lymphoma.
Lung cancer will remain the leading cause of cancer death for men and
women in Iowa in 1998, the report states. The second leading cause of cancer
death for women will be breast cancer, and for men will be prostate cancer.
Colorectal cancer will be the third leading cause of cancer death for both
men and women. "Prostate, lung, colon and rectum, and female breast
cancers will account for more than half of all new cancers and cancer deaths
identified this year," Lynch says.
This year's report includes annual incidence and mortality rates for
breast, lung and prostate cancers among Iowa men and women from 1973-1995.
Rates for newly diagnosed breast cancers peaked in 1988, and the rates
for new prostate cancers peaked in 1992. These trends were due partly to
increased use of mammography and prostate-specific antigen testing, respectively,
which have led to increased detection of these cancers. Cancer death rates
from 1973-1995 for breast cancer and prostate cancer have remained fairly
steady, while female lung cancer mortality rates have been increasing since
1973. Male lung cancer mortality rates peaked in 1988 and have declined
erratically since then.
The report also features a section comparing the percent change in
rates from 1973-75 and 1993-1995 for new cancer cases and cancer deaths
by sex and type of cancer. Both sexes experienced decreases in incidence
and mortality for pancreatic and stomach cancers. Bladder cancer, and childhood
cancers as a group, had increases in incidence, but decreases in mortality.
Acute lymphocytic leukemia, the most common type of childhood cancer, also
showed an increase in incidence and a decrease in mortality. Increases
in both incidence and mortality were seen for cancers of the brain, esophagus,
kidney and renal pelvis, lung and bronchus, and non-Hodgkin's lymphoma.
Lynch notes that most of the incidence and mortality changes cited in this
section of the report are very similar to those reported for the entire
U.S. population by the National Cancer Institute (NCI).
"For cancer prevention and control efforts to be truly successful,
we would like to see decreasing rates for both incidence and mortality,"
Lynch says. "These data demonstrate that we are achieving this for
some cancer types, but not for others. Thus, there remains considerable
room for improvement."
The State Health Registry of Iowa has been recording the occurrence
of cancer in Iowa since 1973. It is one of 10 registries nationwide providing
data to the NCI. The Iowa data represents rural and midwestern populations
and provides information included in many NCI reports and publications.
