Abstract

Abstract : Long-term survivors of childhood cancers are at increased risk for hospitalization. To test the hypothesis that many treatment-related morbidities are identifiable in the early posttherapy period, we determined the rates and causes for hospitalization among survivors of leukemia and lymphoma during the first 3 years posttherapy. Using a health plan claims database, we identified patients aged 0 to 21 years old treated for leukemia or lymphoma from 2000 to 2010. Survivors were matched 10:1 with similar children without a history of cancer. Hospitalization rates over 3 years were compared using Cox proportional hazards regression and risks of cause-specific hospitalization were compared using log-binomial models. Nineteen percent of childhood leukemia and lymphoma survivors were hospitalized in the first 3 years off therapy. Leukemia survivors (N=529) experienced over 6 times (hazard ratio=6.3; 95% confidence interval [CI], 4.9-8.0) and lymphoma survivors (N=454) over 3 times the hospitalization rate of controls (hazard ratio=3.2; 95% CI, 2.5-4.2). Compared with children without a cancer history, survivors were at increased risk for hospitalization due to infectious causes (leukemia: relative risk [RR], 60.0; 95% CI, 23.4-154.0; lymphoma: RR, 10.0; 95% CI, 4.4-22.9). In addition, lymphoma survivors were at increased risk for cardiovascular-related (RR, 15.0; 95% CI, 5.4-42.0) and pulmonary-related (RR, 8.1; 95% CI, 3.9-16.8) hospitalizations. These findings highlight the morbidity experienced by survivors and suggest that treatment-associated complications may be emerging soon after therapy completion.
