A new study suggests that while screening the survivors of childhood cancer for early signs of impending congestive heart failure can lead to improved health outcomes.

"It is important to monitor survivors so we can reduce the late effects of treatment whenever possible, but we may be asking them to be tested too often, which burdens both individuals and the health care system," says senior author Lisa Diller, MD, chief medical officer of Dana-Farber/Boston Children's Cancer and Blood Disorders Center. "We think it is worthwhile to review the current CHF screening guidelines."
"Our findings suggest that there is a long-term benefit in screening survivors at elevated risk for CHF," says lead author Jennifer Yeh, PhD, of the Center for Health Decision Science at Harvard School of Public Health. "Yet less frequent screening than currently recommended may be reasonable when other factors are considered. We hope these results can help inform the ongoing discussion about screening childhood cancer survivors."
As cure rates of pediatric cancers have risen, increasing numbers of survivors are at a substantially higher risk of heart disease, including congestive heart failure, compared to the general population. The increase in risk varies depending on several factors, including whether a patient was treated with anthracyclines, a class of drugs known to cause heart disease, and/or radiation to the heart. For instance, those who received no or low (<250 mg/m2) cumulative doses of anthracyclines have a relatively low lifetime risk of developing CHF, while those who received large (≥250 mg/m2) cumulative doses are at higher risk.
