Ovarian Toxicity in Pediatric Cancer Survivors after Abdominopelvic Radiation Therapy: A Report From the PENTEC (Pediatric Normal Tissue Effects in the Clinic) Initiative

Abstract Background Young cancer survivors are at increased risk of impaired cardiopulmonary fitness (VO2peak) and heart failure. Assessment of exercise cardiac reserve may reveal sub-clinical abnormalities that better explain impairments in fitness and long term heart failure risk. Purpose To investigate the presence of impaired VO2peak in pediatric cancer survivors with increased risk of heart failure, and to assess its relationship with resting cardiac function and cardiac reserve Methods Twenty pediatric cancer survivors (aged 8–24 years) treated with anthracycline chemotherapy underwent cardiopulmonary exercise testing to quantify VO2peak, with a value <85% of predicted defined as impaired VO2peak. Resting cardiac function was assessed using 3-dimensional echocardiography, with cardiac reserve quantified from resting and peak exercise heart rate (HR), stroke volume index (SVi) and cardiac index (CI) using exercise cardiac magnetic resonance imaging. Results 12 of 20 survivors (60%) had impaired VO2peak (97±14% vs. 70±16% of age and gender predicted). There were no differences in echocardiographic or CMR measurements of resting cardiac function between survivors with normal or impaired VO2peak. However, those with reduced VO2peak had diminished cardiac reserve, with a lesser increase in CI (Fig. 1A) and SVi (Fig. 1B) during exercise (Interaction P=0.001 for both), whilst the HR response was similar (Fig. 1C; P=0.71). Conclusions Resting measures of cardiac function are insensitive to significant cardiac dysfunction amongst pediatric cancer survivors with reduced VO2peak. Measures of cardiopulmonary fitness and cardiac reserve may aid in early identification of survivors with heightened risk of long-term heart failure.

Pediatric Cancer Survivors

Abstract Purpose Recent research demonstrated that fear of progression (FoP) is a major burden for adult cancer survivors. However, knowledge on FoP in parents of childhood cancer survivors is scarce. This study aimed to determine the proportion of parents who show dysfunctional levels of FoP, to investigate gender differences, and to examine factors associated with FoP in mothers and fathers. Methods Five hundred sixteen parents of pediatric cancer survivors (aged 0–17 years at diagnosis of leukemia or central nervous system (CNS) tumor) were consecutively recruited after the end of intensive cancer treatment. We conducted hierarchical multiple regression analyses for mothers and fathers and integrated parent-, patient-, and family-related factors in the models. Results Significantly more mothers (54%) than fathers (41%) suffered from dysfunctional levels of FoP. Maternal FoP was significantly associated with depression, a medical coping style, a child diagnosed with a CNS tumor in comparison to leukemia, and lower family functioning (adjusted R2 = .30, p < .001). Paternal FoP was significantly associated with a lower level of education, depression, a family coping style, a child diagnosed with a CNS tumor in comparison to leukemia, and fewer siblings (adjusted R2 = .48, p < .001). Conclusions FoP represents a great burden for parents of pediatric cancer survivors. We identified associated factors of parental FoP. Some of these factors can be targeted by health care professionals within psychosocial interventions and others can provide an indication for an increased risk for higher levels of FoP. Implications for Cancer Survivors Psychosocial support targeting FoP in parents of childhood cancer survivors is highly indicated.
