Soft-tissue sarcoma risk in childhood cancer survivors

AbstractObjectivesAnthracycline cardiotoxicity is an important side-effect in long-term childhood cancer survivors. We evaluated the incidence of and factors associated with anthracycline cardiotoxicity in a population of patients diagnosed with bone or soft tissue sarcoma.Materials and methodsWe retrospectively enrolled patients diagnosed with bone or soft tissue sarcoma, from 1995 to 2011, treated with anthracycline chemotherapy at our Centre and with a follow-up echocardiography carried out ⩾3 years from cardiotoxic therapy completion. Cardiac toxicity was graded using Common Terminology Criteria for Adverse Events version 4.0.ResultsA total of 82 patients were eligible. The median age at treatment was 11.9 years (1.44–18). We evaluated the median cumulative anthracycline dose, age at treatment, sex, thoracic radiotherapy, hematopoietic stem cell transplantation, and high-dose cyclophosphamide treatment as possible risk factors for cardiotoxicity. The median cumulative anthracycline dose was 390.75 mg/m2(80–580). Of the 82 patients, 12 (14.6%) developed cardiotoxicity with grade ⩾2 ejection fraction decline: four patients were asymptomatic and did not receive any treatment; six patients were treated with pharmacological heart failure therapy; one patient with severe cardiomyopathy underwent heart transplantation and did not need any further treatment; and one patient died while waiting for heart transplantation. The median time at cardiac toxicity, from the end of anthracycline frontline chemotherapy, was 4.2 years (0.05–9.6). Cumulative anthracycline dose ⩾300 mg/m2(p 0.04) was the only risk factor for cardiotoxicity on statistical analyses.ConclusionsIn our population, the cumulative incidence of cardiotoxicity is comparable to rates in the literature. This underlines the need for primary prevention and lifelong cardiac toxicity surveillance programmes in long-term childhood cancer survivors.

Neuromuscular Dysfunction

10546 Background: Childhood cancer survivors are at risk for neuromuscular dysfunction. We estimated the prevalence and cumulative incidence of neuromuscular dysfunction in a cohort of childhood cancer survivors and examined associations with treatment exposures and health/socioeconomic outcomes. Methods: CCSS participants ≥5 years from cancer diagnosed between 1970-1999 (n = 25,583, 46.5% female, median [range] age 54.4 [15.1-57.6] years) and siblings (n = 5,044, 52.3% female, median [range] age 54.1 [32.5-57.0] years) were included. Neuromuscular dysfunction was identified by self-report of 1) motor dysfunction: impaired balance, tremor, or extremity weakness; 2) sensory dysfunction: impaired touch sensation. Multivariable analyses examined predictors of dysfunction by diagnosis. Results: Cumulative incidence of neuromuscular dysfunction was elevated at 20 years from diagnosis in survivors (24.3%, 95% CI 23.8-24.8; motor 18.2%, sensory 13.5%) versus siblings (8.9%, 95% CI 8.1-9.7). In survivors five years from diagnosis, motor dysfunction was associated with exposure to cytarabine (OR = 1.39, 95% CI 1.10-1.77) and spinal radiation (OR = 2.11, 95% CI 1.31-3.41) in acute lymphoblastic leukemia/non-hodgkin lymphoma (ALL/NHL), vinca alkaloids (OR 1.29, 95% CI 1.03-1.60) and brain radiation (OR = 1.58, 95% CI 1.35-1.85) in central nervous system tumors, and cytarabine (OR = 3.73, 95% CI 1.62-8.57) and non-brain/spine radiation (OR = 1.84, 95% CI 1.42-2.40) in bone/soft tissue tumors. Sensory dysfunction was associated with exposure to vinca alkaloids (OR = 3.45, 95% CI 1.06-11.22) in ALL/NHL, and platinum agents (OR = 1.31, 95% CI 1.03-1.67) and spinal radiation (OR = 3.71, 95% CI 1.24-11.11) in bone/soft tissue tumors. Survivors with neuromuscular dysfunction were at increased risk for adverse health/socioeconomic outcomes (Table). Conclusions: Neuromuscular dysfunction is a prevalent morbidity in childhood cancer survivors, associated with specific therapies within a particular diagnosis. Interventions are needed to identify and improve neuromuscular dysfunction given its association with adverse health/socioeconomic outcomes. [Table: see text]
