概要
OBJECTIVE
To explore the risk factors for hepatoblastoma.
METHODS
A case-cohort study using Logistic regression multiple variables analysis of medical record data sets was conducted to examine infant and perinatal risk factors for hepatoblastoma.
RESULTS
Birth weight less than 1,000 g was associated with a strongly increased risk of hepatoblastoma (odds risk, OR = 26.0, 95% confidence interval, CI: 14.0 to 65.7). After adjustment of birth weight, a moderately increased risk of hepatoblastoma was found for older maternal age ( > 35 years vs. 20 to 34 years: OR = 2.6, 95% CI: 0.9 to 5.9), maternal smoking (OR = 2.9, 95% CI: 1.1 to 4.2) and higher maternal pregnancy body mass index (OR = 3.2, 95% CI: 1.0 to 6.7).
CONCLUSIONS
Very low birth weight and maternal characteristics including overweight, smoking are associated with hepatoblastoma risk.
