Although new treatments have improved the survival chances of patients with Hodgkin lymphoma (HL), these therapies can also increase the risk of cardiovascular disease (CVD). A recent study published in CANCER reveals that people with early-stage HL, which affects the lymphatic system, are now at higher risk of dying from CVD than from cancer.
The multicentre study included 15 889 children and adults in the United States who were diagnosed with HL between 1983 and 2015. “We conducted this study because cardiovascular disease may be the most common non-malignant long-term complication and a prevalent cause for non-malignant death following treatment in HL survivors,” said senior author Caiwen Ou, MD, PhD, of Southern Medical University in China.
Prof Ou and colleagues found that among patients with stage I and stage II classic HL, the proportion of CVD mortality exceeded the proportion of classic HL mortality after about 60 and 120 months of follow-up, respectively. The cumulative incidence of CVD mortality also exceeded that of HL and other cancers over time. In recent decades, the mortality risk from classic HL dropped sharply, but CVD mortality risk among patients with classic HL fell slowly or even remained unchanged among some groups.
The analysis also revealed that patients with stage I or stage II classic HL experienced a higher risk of CVD mortality than the general population at almost all follow-up intervals.
“Our results indicate that more effective measures are needed to reduce the risk of cardiovascular disease-related deaths in classic HL survivors,” said co-author Weijing Feng, MD, PhD.
