Insights
Cancer rates in U.S. infants increased between 1979-1991, particularly for males. Further research into genetic and environmental factors is needed to understand these trends in infant cancer.
Area of Science:
- Pediatric Oncology
- Epidemiology
- Public Health
Background:
- Childhood cancer incidence in the U.S. rose during the 1980s.
- The trend of infant cancer, distinct from older children, remained unclear.
Purpose of the Study:
- To assess changes in cancer incidence among U.S. infants (age < 1 year) from 1979 to 1991.
- To identify specific cancer types and demographic differences in infant cancer rates.
Main Methods:
- Utilized data from the Surveillance, Epidemiology, and End Results (SEER) program.
- Employed U.S. Bureau of the Census data to calculate population-based cancer incidence rates.
- Analyzed age-specific incidence rates for infants under one year of age.
Main Results:
- Overall infant cancer rates increased from 189 to 220 cases per million between 1979-1981 and 1989-1991.
- Male infants showed a significant increase in rates for central nervous system (CNS) tumors, neuroblastoma, and retinoblastoma.
- Female infants experienced increased rates of teratomas and hepatoblastomas; both sexes had higher rates than previously observed.
Conclusions:
- The incidence of certain cancers in U.S. infants has demonstrably increased.
- Investigating genetic and environmental factors is crucial to elucidate the rising rates and shifting patterns of infant cancers.
- Understanding these trends is vital for developing targeted prevention and treatment strategies.
Background:
During the decade between 1980-1990, the rate of cancer in children in the U.S. increased. It is unknown whether cancer in infancy, which is biologically and clinically different from cancer in older children, also increased.
Methods:
To evaluate changes in cancer incidence in infants in the U.S. age < 1 year, data from the Surveillance, Epidemiology, and End Results (SEER) program and the U.S. Bureau of the Census were used to construct age specific, population-based cancer incidence rates.
Results:
Overall, the annual cancer rate in infants increased from 189 cases per million infants between 1979-1981 to 220 between 1989-1991. At both timepoints, female infants had higher cancer rates than male infants. Although the rates for female infants remained stable at 223 between 1979-1981 versus 236 between 1989-1991, rates for male infants increased from 158 to 205 during the same timepoints. Male infants had increased rates of central nervous system (CNS) tumors (P < 0.05), neuroblastoma, and retinoblastoma; female infants had increased rates of teratomas (P < 0.01) and hepatoblastomas. Between 1979-1981, the three most common types of cancer in infants were neuroblastoma, leukemia, and renal tumors (27%, 15%, and 14%, respectively), and were neuroblastoma, CNS tumors, and leukemia between 1989-1991 (27%, 15%, and 13%, respectively).
Conclusions:
This study shows that the rate of certain types of cancer in infants in the U.S. is increasing. Studies of both genetic and environmental factors are needed to explain these increased rates and the changing distribution of cancer in the first year of life.
