ABSTRACT
PURPOSE: Neuroblastoma (NB) is the most common extracranial solid malignancy during childhood. Despite a multimodal treatment approach, the prognosis of patients with metastatic NB is not satisfactory. Although radiotherapy (RT) has become an integral part of treatment of the primary tumor, the role of RT in osteomedullary lesions is not well defined. A retrospective analysis was conducted to evaluate the impact of RT for metastatic sites in children with high-risk NB. METHODS: All patients with stage 4 NB from the prospective, multicenter NB trials NB97 and NB2004 who received RT to metastatic sites during frontline treatment were included in this retrospective analysis. RESULTS: A total of 18 children were irradiated with a median dose of 36 Gray (Gy; range 20-45â¯Gy) to one or more (range 1-3) osteomedullary metastases with or without concomitant RT to the primary tumor site. The median follow-up time was 149 months (range 55-220) in survivors. At 5 years, local relapse-free survival (LRFS) at irradiated metastatic sites and metastases-free survival (MFS) at distant, non-irradiated site rates were 51.4 and 39.9%, respectively. The estimated overall survival (OS) rate at 5 years was 49.4%. No high-grade acute or late toxicity and no secondary malignancy was reported. CONCLUSION: RT to metastases is feasible for patients with stage 4 NB. However, an impact of RT to residual metastatic sites on outcome was not found. Studies with larger cohorts or prospective trials would be desirable in order to elucidate the role of RT for metastases.

BACKGROUND: Empirical evidence supporting the benefits of dietary recommendations for patients with advanced heart failure is scarce. We prospectively evaluated the relation of dietary habits to pre-transplant clinical outcomes in the multisite observational Waiting for a New Heart Study. METHODS AND RESULTS: A total of 318 heart transplant candidates (82% male, age 53 ± 11 years) completed a Food Frequency Questionnaire (foods high in salt, saturated fats, poly-/monounsaturated fats [PUFA+MUFA], fruit/vegetables/legumes, and fluid intake) at time of waitlisting. Cox proportional hazard models controlling for heart failure severity (eg, Heart Failure Survival Score, creatinine) estimated cause-specific hazard ratios (HRs) associated with each dietary habit individually, and with all dietary habits entered simultaneously. During follow-up (median 338 days, range 13-1,394), 54 patients died, 151 received transplants (110 in high-urgency status, 41 electively), and 45 became delisted (15 deteriorated, 30 improved). Two robust findings emerged: Frequent intake of salty foods, which correlated positively with saturated fat and fluid intake, was associated with transplantation in high-urgency status (HR 2.90, 95% confidence interval [CI] 1.55-5.42); and frequent intake of foods rich in PUFA+MUFA reduced the risk for death/deterioration (HR 0.49, 95% CI 0.26-0.92). CONCLUSIONS: These results support the importance of dietary habits for the prognosis of patients listed for heart transplantation, independently from heart failure severity.

It is unclear to what extent patients awaiting heart transplantation (HTx) engage in physical activities. We examined the everyday physical activity and its associations with depressive symptoms and disease severity in 318 patients newly registered for HTx in the multi-site study 'Waiting for a New Heart' (aged 53.5 +/- 11.4 years, 18% female patients). Participants completed questionnaires assessing depressive symptomatology and physical activity (number of physical activities, caloric expenditure associated with each activity), and estimated the distance they were able to walk without a break. Medical parameters at the time of listing [e.g. peak oxygen consumption (peakVO(2)); the German Transplant Society Score (GTSS)] were provided by Eurotransplant. Almost 50% of patients engaged in activities of daily living (housework, walking), but <10% engaged in regular exercise. All physical activity measures correlated significantly with peakVO(2) (Ps < 0.01). Elevated depression scores were present in 39% of patients. Controlling for confounding variables (e.g. peakVO(2), diastolic blood pressure, GTSS, age), depressive symptomatology accounted for additional variance in all physical activity measures (Ps < 0.05). The association of depressive symptoms with reduced physical activity suggests two important perspectives: attempts to increase physical activity (especially in the area of daily living) might benefit from targeting depression, and increased physical activity might also help to reduce depressive symptoms.
