In bid to make child cancer treatments safer, scientists find possible warning signs of severe reaction

Researchers have found a possible early warning indicator for adverse reactions to childhood cancer treatments. Low levels of vitamin A in the liver and blood may signal an increased risk of pancreatitis, a potentially life-threatening complication of asparaginase treatment. Increasing dietary vitamin A levels may help reduce this risk.
