Abstract

The outcomes of adolescents/young adults with osteosarcoma have not improved in decades. The chaotic karyotype of this rare tumor has precluded the identification of prognostic biomarkers and patient stratification. We reasoned that transcriptomic studies should overcome this genetic complexity. RNA sequencing (RNA-seq) of 79 osteosarcoma diagnostic biopsies identified stable independent components that recapitulate the tumor and microenvironment cell composition. Unsupervised classification of the independent components stratified this cohort into favorable (G1) and unfavorable (G2) prognostic tumors in terms of overall survival. Multivariate survival analysis ranked this stratification as the most influential variable. Functional characterization associated G1 tumors with innate immunity and G2 tumors with angiogenic, osteoclastic, and adipogenic activities as well as PPARγ pathway upregulation. A focused gene signature that predicted G1/G2 tumors from RNA-seq data was developed and validated within an independent cohort of 82 osteosarcomas. This signature was further validated with a custom NanoString panel in 96 additional osteosarcomas. This study thus proposes new biomarkers to detect high-risk patients and new therapeutic options for osteosarcoma.Significance:These findings indicate that the osteosarcoma microenvironment composition is a major feature to identify hard-to-treat patient tumors at diagnosis and define the biological pathways and potential actionable targets associated with these tumors.

Abstract

BACKGROUND: HIT-SKK protocol is used for the treatment of low risk medulloblastomas in young children with the aim of eliminating cranial irradiation and its long-term side effects, in particular neuropsychological (NP) sequelae. This therapy includes IV and intraventricular (ITV) methotrexate (MTX) potentially responsible for leukoencephalopathy (LE) and neurocognitive disorders.The objectives are to describe the risk factors and the course of LE, and to investigate its impact on long-term neurocognitive and behavioural outcome. METHODS: A French retrospective, multicenter study including 35 children under 5 years of age, treated between 2009 and 2017, with a median follow up of 72 months. All follow-up MRIs including assessment of the severity of the LE (Fazekas and CTCAE grading) and all NP evaluations were centrally rewieved. RESULTS: 25/34 evaluable patients presented a LE during follow up, in a median delay of 2 months (1 - 17 months) after the start of chemotherapy. Grade 2 and 3 abnormalities were correlated with higher cumulative dose of ITV -MTX (p=0,01). Full Scale IQ (FSIQ) and Wechsler indexes were in the average or low average of the reference population. FSIQ was deficient in 7/20 evaluable patients. Processing speed (PSI) was the most frequently impaired neurocognitive domain: 9/20 patients with borderline or very low score, all having received a significantly higher cumulative dose of ITV-MTX (p=0,04). A decrease in overall NP scores was observed in patients for whom grade 2 or 3 LE persisted at the end of follow-up with an average FSIQ estimated at 82.1 (SD 16.9) versus 94.2 (SD 20.6). This decrease was significant for PSI (p=0,049). LE and neurocognitive impairments were not correlated with a younger age at diagnosis. CONCLUSION: This study confirmed the responsibility of MTX, and in particular ITV-MTX therapy in the onset and, most often, persistence of LE and its association with neurocognitive disorders.

Abstract

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.

Abstract

Noninfectious manifestations-allergy, autoimmunity/inflammation, lymphoproliferation, and malignancies-are known to exist in many primary immunodeficiency diseases (PID) and to participate in prognosis.To obtain a global view on their occurrence, we retrieved data from a retrospective cohort of 1375 patients included in the French National Reference Center for Primary Immune Deficiencies (CEREDIH) for whom we had a 10-year follow-up since inclusion in the registry.These patients were followed for 10 years (2009-2018) by specialized centers in university hospitals. This study showed that 20.1% of patients without prior curative therapy (n = 1163) developed at least 1 manifestation (event) encompassing 277 events.Autoimmune/inflammatory events (n = 138) and malignancies (n = 85) affected all age classes and virtually all PID diagnostic groups. They were associated with a risk of death that occurred in 195 patients (14.2%) and were found to be causal in 43% of cases. Malignancies (odds ratio, 5.62; 95% confidence interval, 3.66-8.62) and autoimmunity (odds ratio, 1.9; 95% confidence interval, 1.27-2.84) were clearly identified as risk factors for lethality. Patients who underwent curative therapy (mostly allogeneic hematopoietic stem cell transplantation, with a few cases of gene therapy or thymus transplantation) before the 10-year study period (n = 212) had comparatively reduced but still detectable clinical manifestations (n = 16) leading to death in 9.4% of them.This study points to the frequency and severity of noninfectious manifestations in various PID groups across all age groups. These results warrant further prospective analysis to better assess their consequences and to adapt therapy, notably indication of curative therapy.

Abstract

Purpose The purpose of this work is to assess the clinical outcome of pediatric patients diagnosed with pheochromocytoma and paraganglioma (PPGL) detected in France since 2000. Methods A retrospective multicenter study was conducted that included all patients younger than 18 years with PPGL diagnosed in France between 2000 and 2016. Patients were identified from 4 different sources: the National Registry of Childhood Solid Tumors, the French Pediatric Rare Tumors Database, the French registry of succinate dehydrogenase (SDH)-related hereditary paraganglioma, and the nationwide TenGen network. Results Among 113 eligible patients, 81 children with available data were enrolled (41 with adrenal and 40 with extra-adrenal PPGL). At diagnosis, 11 had synchronous metastases. After a median follow-up of 53 months, 27 patients experienced a new event (n = 7 second PPGL, n = 1 second paraganglioma [PGL], n = 8 local recurrences, n = 10 metastatic relapses, n = 1 new tumor) and 2 patients died of their disease. The 3- and 10-year event-free survival rates were 80% (71%-90%) and 39% (20%-57%),respectively, whereas the overall survival rate was 97% (93%-100%)at 3 and 10 years. A germline mutation in one PPGL-susceptibility gene was identified in 53 of the 68 (77%) patients who underwent genetic testing (SDHB [n = 25], VHL [n = 21], RET [n = 2], HIF2A [n = 2], SDHC [n = 1], SDHD [n = 1], NF1 [n = 1]). Incomplete resection and synchronous metastases were associated with higher risk of events (P = .011, P = .004), but presence of a germline mutation was not (P = .11). Conclusions Most pediatric PPGLs are associated with germline mutations and require specific follow-up because of the high risk of tumor recurrence.

Abstract

International audience; The nucleoside analogue, 2-chlorodeoxyadenosine (2CDA), was reported to be an active treatment for childhood Langerhans cell histiocytosis (LCH) without risk organ (RO−) involvement. However, we lack data on long-term effects of 2CDA treatment, including the disease reactivation rate, permanent sequelae and long-term tolerance. This study included 44 children from the French LCH registry, treated for a RO− LCH with 2CDA monotherapy (median number of six courses). The median age at the beginning of 2CDA was 3·6 years (range, 0·3–19·7 years) and the median follow-up after was 5·4 years (range, 0·6–15·1 years). Objective response to 2CDA was observed in 25 patients (56·8%), while six patients (13·6%) had stable disease and 13 patients (29·5%) exhibited progressive disease. Among patients without progression, only two experienced disease reactivation after 2CDA discontinuation. The five-year cumulative incidence of disease progression or reactivation after 2CDA therapy initiation was 34·3%. The lymphopenia reported in all cases [72% below absolute lymphocyte count (ALC) of 0·5 G/l], was addressed with appropriate prophylactic measures. Other toxicities above grade 2 were uncommon, and no second malignant neoplasm or neuropathy was reported. The five-year overall survival was 97·7%. In conclusion, we could confirm that 2CDA monotherapy was a beneficial long-term therapy for treating patients with RO− LCH. Appropriate management of induced immune deficiency is mandatory.

Abstract

International audience; To the Editor:Since the mid-1980s, continuous progress in genetics and genomics has accelerated the rapid identification of causative genetic variants leading to primary immunodeficiencies (PIDs; >300 genes),1 with the noticeable exception of B-cell disorders, such as common variable immunodeficiency (CVID). The identification of these mutations not only validates a clinical diagnosis but also is useful in several other respects (more accurate prognosis on phenotype/genotype correlation, targeted therapy, and genetic counseling).

Abstract

Background Germline non-polyalanine repeat expansion mutations in PHOX2B (PHOX2B NPARM) predispose to peripheral neuroblastic tumors (PNT), frequently in association with other neurocristopathies: Hirschsprung disease (HSCR) or congenital central hypoventilation syndrome (CCHS). Although PHOX2B polyalanine repeat expansions predispose to a low incidence of benign PNTs, the oncologic phenotype associated with PHOX2B NPARM is still not known in detail. Methods We analyzed prognostic factors, treatment toxicity, and outcome of patients with PNT and PHOX2B NPARM. Results Thirteen patients were identified, six of whom also had CCHS and/or HSCR, one also had late-onset hypoventilation with hypothalamic dysfunction (LO-CHS/HD), and six had no other neurocristopathy. Four tumours were “poorly differentiated,” and nine were differentiated, including five ganglioneuromas, three ganglioneuroblastomas, and one differentiating neuroblastoma, hence illustrating that PHOX2B NPARM are predominantly associated with differentiating tumors. Nevertheless, three patients had stage 4 and one patient had stage 3 disease. Segmental chromosomal alterations, correlating with poor prognosis, were found in all the six tumors analyzed by array-comparative genomic hybridization. One patient died of tumor progression, one is on palliative care, one died of hypoventilation, and 10 patients are still alive, with median follow-up of 5 years. Conclusions Based on histological phenotype, our series suggests that heterozygous PHOX2B NPARM do not fully preclude ganglion cell differentiation in tumors. However, this tumor predisposition syndrome may also be associated with poorly differentiated tumors with unfavorable genomic profiles and clinically aggressive behaviors. The intrafamilial variability and the unpredictable tumor prognosis should be considered in genetic counseling. Pediatr Blood Cancer 2015; 9999:XX–XX © 2015 Wiley Periodicals, Inc.

Abstract

About one third of patients with rhabdoid tumors (RT) harbor a heterozygous germline variant in SMARCB1. Molecular diagnosis therefore keeps a crucial place in the diagnosis of RT, and genetic counseling should be systematically recommended. However, immunohistochemistry has progressively replaced molecular tools to assess the status of SMARCB1 in tumors; the necessity of analyzing SMARCB1 status in the tumor may thus be less considered by neuropathologists and pediatric neuro-oncologists. In the present manuscript as aforementioned, we report on two patients with bifocal RT in the first month of life and in whom no germline variant was initially found in the SMARCB1 coding sequence. Careful analysis of SMARCB1 status in the tumors revealed that only one of the two inactivating hits was found in the coding sequence. By sequencing the tumor cells RNA, we were able to detect an insertion with an abnormal sequence, due to the same intronic variant of SMARCB1, which led to the exonisation of the first intron. This cryptic variant was absent in the germline DNA of both patients. Of note, we previously reported one patient with the same deep intronic variant in the germline in a soft tissue RT. To our mind, this additional report on two patients clearly demonstrates that this intronic variant is a new hotspot that should now be systematically added to the germline screening of SMARCB1. We therefore recommend searching for and cautiously interpreting germline analysis if SMARCB1 has not been extensively studied in the tumor.

Abstract

Germline non-polyalanine repeat expansion mutations in PHOX2B (PHOX2B NPARM) predispose to peripheral neuroblastic tumors (PNT), frequently in association with other neurocristopathies: Hirschsprung disease (HSCR) or congenital central hypoventilation syndrome (CCHS). Although PHOX2B polyalanine repeat expansions predispose to a low incidence of benign PNTs, the oncologic phenotype associated with PHOX2B NPARM is still not known in detail.We analyzed prognostic factors, treatment toxicity, and outcome of patients with PNT and PHOX2B NPARM.Thirteen patients were identified, six of whom also had CCHS and/or HSCR, one also had late-onset hypoventilation with hypothalamic dysfunction (LO-CHS/HD), and six had no other neurocristopathy. Four tumours were "poorly differentiated," and nine were differentiated, including five ganglioneuromas, three ganglioneuroblastomas, and one differentiating neuroblastoma, hence illustrating that PHOX2B NPARM are predominantly associated with differentiating tumors. Nevertheless, three patients had stage 4 and one patient had stage 3 disease. Segmental chromosomal alterations, correlating with poor prognosis, were found in all the six tumors analyzed by array-comparative genomic hybridization. One patient died of tumor progression, one is on palliative care, one died of hypoventilation, and 10 patients are still alive, with median follow-up of 5 years.Based on histological phenotype, our series suggests that heterozygous PHOX2B NPARM do not fully preclude ganglion cell differentiation in tumors. However, this tumor predisposition syndrome may also be associated with poorly differentiated tumors with unfavorable genomic profiles and clinically aggressive behaviors. The intrafamilial variability and the unpredictable tumor prognosis should be considered in genetic counseling.

Abstract

International audience; BACKGROUND:Primary immunodeficiencies (PIDs) are inherited diseases associated with a considerable increase in susceptibility to infections. It is known that PIDs can also predispose to cancer and immune diseases, including allergy, autoimmunity, and inflammation.OBJECTIVE:We aimed at determining the incidence of autoimmunity and inflammation in patients with PIDs.METHODS:We have retrospectively screened 2183 consecutive cases of PID in the Centre de Référence Déficits Immunitaires Héréditaires registry (CEREDIH; the French national PID registry) for the occurrence of autoimmunity and inflammation.RESULTS:One or more autoimmune and inflammatory complications were noted in 26.2% of patients, with a risk of onset throughout the patient's lifetime. The risk of autoimmune cytopenia was at least 120 times higher than in the general population, the risk of inflammatory bowel disease in children was 80 times higher, and the risk of other autoimmune manifestations was approximately 10 times higher. Remarkably, all types of PIDs were associated with a risk of autoimmune and inflammatory complications, although the greatest risk was associated with T-cell PIDs and common variable immunodeficiency. The occurrence of autoimmune disease is a negative prognostic factor for survival.CONCLUSIONS:Our results provide the basis for a detailed prospective evaluation of autoimmunity and inflammation in the context of PIDs, with a view to accurately assessing these risks and describing the possible effect of medical intervention.
