Cardiovascular Disease Risks In Younger And Older B-Cell Non-Hodgkin'S Lymphoma Survivors

Introduction. Non-Hodgkin9s lymphoma (NHL) is the fifth most common cancer in the United States. B-cell lymphoma accounts for 80-90% of NHL cases. Younger age at cancer diagnosis is associated with higher survival rates. However, younger cancer survivors may experience accelerated aging due to the cancer treatment that they undergo. The aim of this population-based study is to estimate long-term cardiovascular risk among younger and older adult NHL survivors compared to their respective general population cohorts. Methods. B-cell non-Hodgkin9s lymphoma (B-NHL) survivors diagnosed from 1997 to 2015 in the Utah Cancer Registry were matched with up to five cancer-free individuals on birth year, sex, birth state, using the statewide Utah Population Database. Electronic medical records and statewide healthcare facility data were used to identify disease outcomes 5 years or more after cancer diagnosis. Cox Proportional Hazards models were used to estimate hazard ratios (HR). Test for heterogeneity was used to compare the HR for the older and younger cohorts. Results. There were 2,146 B-NHL survivors (1,284 diagnosed Conclusion. Elevated long-term risk for congestive heart failure was observed in B-NHL survivors compared to the general population. Younger B-NHL survivors had higher relative risks than older B-NHL survivors for chronic rheumatic heart disease, peri-; endo-; and myocarditis, and cardiomyopathy compared to their respective general population cohort groups. Although these increased disease risks suggest some early aging for young B-NHL survivors, most cardiovascular disease risks were not different between the two age groups.
