Background: In adults, there is a link between socioeconomic status (SES) and cancer prognosis, notably due to increased time to diagnosis (TTD) in deprived population leading to the spread of the disease. In children, such an association has not been clearly reported. The objective of our study was to assess the impact of SES on TTD of childhood cancer and its potential consequences on cancer prognosis. Methods: We carried out a multicenter retrospective study based on the LOGAFTER multicentric database. We studied the SES at the individual and ecological levels. Results: Overall, 854 children were included. The median time to diagnosis was 28 days [12;64]. A usual care pathway did not seem to impact TTD, but the use of alternative medicine and an initial management by professionals not usually involved in the specific childhood cancer context increased TTD. None of the SES ecological variables were strictly associated with a significant impact on TTD. However, we noted strong trends for single-parent families and children whose fathers had died who presented with an increased TTD. Conclusions: In the current study, the impact of SES on TTD in children on both the individual and ecological levels was not clear. However, we noted some keys at the individual scale that require further investigation to explain a potential association between deprivation and TTD.

Background The posttreatment period is a key part of the management of pediatric cancer care. At this period, psychosocial effects (scholarly and psychological difficulties) have been described in pediatric cancer patients and can be prognostic for the success of social reintegration. Psychosocial effects and their impact may be related to the household’s socioeconomic background. The aim of this study was to estimate psychosocial difficulties during the posttreatment period based on a social deprivation score. Design This study is based on a prospective multicentric study database, and focused on the children who had received psychosocial evaluation during their follow-up after cancer treatment since 01/01/2013. We retrieved data on their learning and psychological difficulties. Socioeconomic status of the household was estimated by a social deprivation score. Results 1003 patients were analyzed. Learning difficulties at school were noted in 22% of patients. A greater social deprivation was significantly associated with learning difficulty (OR=1.09 per unit of the deprivation score). Tumor relapse, treatment with hematopoietic stem cell transplantation, and diagnosis of a CNS tumor remained significant risk factors. In the subgroup analysis of children with CNS tumors, learning difficulties were increased and associated with greater social deprivation. By contrast, psychological difficulties were not associated with the deprivation score. Conclusion There is a link between SE status and learning difficulties in survivors of childhood cancer. Further investigations should be carried out to confirm these results for children with CNS tumors, which is the population of the greatest concern.

Objective Ovarian mature teratoma (OMT) is a common ovarian tumor found in the pediatric population. In 10% to 20% of cases, OMT occurs as multiple synchronous or metachronous lesions on ipsi- or contralateral ovaries. Ovarian sparing surgery (OSS) is recommended to preserve fertility, but total oophorectomy (TO) is still performed. This study reviews the clinical data of patients with OMT, and analyzes risk factors for second events. Design A retrospective review of all girls under 18 years of age with OMTs was performed. Data on clinical features, imaging, laboratory studies, surgical reports, follow-up second events and their management were retrieved. Results Overall, 350 children were identified. Eighteen patients (5%) presented with a synchronous bilateral form at diagnosis. Surgery was performed by laparotomy (85%) and laparoscopy (15%). OSS and TO were performed in 59% and 41% of cases respectively. Perioperative tumor rupture occurred in 23 cases, independently of the surgical approach. Twenty-nine second events occurred (8.3%) in a median time of 30.5 months from diagnosis (ipsilateral: 8 cases including one malignant tumor, contralateral: 18 cases, both ovaries: 3 cases). A large palpable mass, bilateral forms at diagnosis and perioperative rupture had a statistical impact on the risk of second event, whereas type of surgery or approach did not. Conclusion This study is a plea in favor of OSS as the first choice of treatment of OMT when possible. Close follow-up during the first five years is mandatory considering the risk of 8.3% of second events especially in cases with risk factors.
