Abstract
Modern cancer therapy has led to a growing number of pediatric and young adult cancer survivors, who are prone to increased morbidities caused by the late effects of therapy. The aim of our study was to investigate pediatric and young adult cancer survivors' morbidity due to renal and bone metabolism diseases and especially to study bone metabolism in cancer survivors with renal disease. Patients were identified from the Finnish Cancer Registry, and the cohort consisted of 13,860, 5-year survivors of cancer diagnosed below the age of 35years. Healthy siblings were used as the comparison cohort. Information on the main outcomes was linked from the national Care Register for Health Care. Hazard ratios (HRs) comparing cancer survivors to siblings were calculated for various outcomes. The patient cohort was separated into two age groups, pediatric (0-19years) and young adults (20-34years). Significantly elevated HRs (p<0.0001) in survivors were observed in both age groups for scoliosis (HR 1.6, 95% confidence interval [CI] 1.3-2.0), osteoporosis (HR 5.2, 95% CI 2.4-11.4), osteonecrosis (HR 12.7, 95% CI 5.4-29.7), nephritis (HR 1.9, 95% CI 1.5-2.2) and kidney failure (HR 3.6, 95% CI 2.4-5.3) for all. For cancer survivors with a renal outcome, the risk for developing any outcome of bone metabolism was increased (HR 2.3, 95% CI 1.4-3.6). These results show that pediatric and young adult cancer survivors have an elevated risk for long-term, adverse outcomes related to renal function and bone metabolism. These results suggest follow-up care for young cancer patients.What's new? Increased survival following childhood and young-adult cancers has led to a growing number of people with long-term, late effects caused by early treatment. In this study, the authors found that underlying renal dysfunction predisposes pediatric and young adult cancer survivors to renal complications later in life. Renal disease also increased the risk for impaired bone metabolism, which further heightens the risk of fractures. As the risk for later health problems related to bone metabolism is already increased after cancer treatment, these results suggest special follow-up care is needed for young cancer patients.
