Chemo-immunotherapy with dinutuximab beta in patients with relapsed/progressive high-risk neuroblastoma: does chemotherapy backbone matter? Eur J Cancer 2024; 202:114001. [PMID: 38489858 DOI: 10.1016/j.ejca.2024.114001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/27/2024] [Accepted: 02/28/2024] [Indexed: 03/17/2024]
Abstract
BACKGROUND Addition of anti-GD2 antibodies to temozolomide-based chemotherapy has demonstrated increased antitumor activity and progression-free survival in patients with relapsed/progressive high-risk neuroblastoma. However, chemo-immunotherapy is not yet approved for this indication. This study presents the chemo-immunotherapy experience in patients with relapsed/progressive high-risk neuroblastoma treated within the off-label use program of the Neuroblastoma Committee of the French Society of Pediatric Oncology (SFCE). METHODS Dinutuximab beta (dB) was administered alongside temozolomide-topotecan (TOTEM) or temozolomide-irinotecan (TEMIRI) at first disease relapse/progression or topotecan-cyclophosphamide (TopoCyclo) at further relapse/progression. Real-world data on demographics, treatment, antitumor activity and safety was collected from all patients after inclusion in SACHA-France (NCT04477681), a prospective national registry, which documents safety and efficacy data on innovative anticancer therapies prescribed to patients ≤ 25 years old as compassionate or off-label use. RESULTS Between February 2021 and July 2023, 39 patients with confirmed relapsed/progressive high-risk neuroblastoma (median age 6 years, range 1-24) were treated with dB+TopoCyclo (n = 24) or dB+TOTEM/TEMIRI (n = 15) across 17 centers. In total, 163 chemo-immunotherapy cycles were administered, main toxicities were mild or moderate, with higher incidence of hematological adverse drug reactions with dB+TopoCyclo than dB+TOTEM/TEMIRI. Objective response rate was 42% for dB+TopoCyclo (CI95% 22-63%) and 40% for dB+TOTEM/TEMIRI (CI95% 16-68%). CONCLUSION Similar objective response rates for dB+TopoCyclo and dB+TOTEM/TEMIRI in patients with relapsed/progressive high-risk neuroblastoma emphasize the importance of chemo-immunotherapy, irrespective of the chemotherapy backbone.

The French FRACTURE database: A way to improve knowledge on management of children with very rare tumors. Pediatr Blood Cancer 2022; 69:e30003. [PMID: 36156381 DOI: 10.1002/pbc.30003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 07/28/2022] [Accepted: 08/29/2022] [Indexed: 11/11/2022]
Abstract
INTRODUCTION Very rare pediatric tumors (VRTs), defined by an annual incidence ≤2 per million inhabitants, represent a heterogeneous group of cancers. Due to their extremely low incidence, knowledge on these tumors is scant. Since 2012, the French Very Rare Tumors Committee (FRACTURE) database has recorded clinical data about VRTs in France. This study aims: (a) to describe the tumors registered in the FRACTURE database; and (b) to compare these data with those registered in the French National Registry of Childhood Cancer (RNCE). METHODS Data recorded in the FRACTURE database between January 1, 2012 and December 31, 2018 were analyzed. In addition, these data were compared with those of the RNCE database between 2012 and 2015 to evaluate the completeness of the documentation and understand any discrepancies. RESULTS A total of 477 patients with VRTs were registered in the FRACTURE database, representing 97 histological types. Of the 14 most common tumors registered in the RNCE (772 patients), only 19% were also registered in the FRACTURE database. Total 39% of children and adolescent VRTs registered in the RNCE and/or FRACTURE database (323 of a total of 828 patients) were not treated in or linked to a specialized pediatric oncology unit. CONCLUSION VRTs represent many different heterogenous entities, which nevertheless account for 10% of all pediatric cancers diagnosed each year. Sustainability in the collection of these rare tumor cases is therefore important, and a regular systematic collaboration between the FRACTURE database and the RNCE register helps to provide a more exhaustive picture of these VRTs and allow research completeness for some peculiar groups of patients.

Abstract
In recent decades, follow-up of cancer survivors has taken on its full meaning with the gradual improvement in the survival of children and adolescents with cancer. This follow-up is associated specially for adolescents with a multitude of transitions: the transition from therapeutic management to the monitoring for possible relapse, the transition into long-term follow-up after childhood cancer, the transition from a pediatric system to an adult care system. If this transition can be perceived as difficult by patients, it gives young people the opportunity to access more autonomous follow-up and support in becoming an adult. Supporting the transition should make caregivers attentive to this time of consolidation of adolescence, favorable to the emergence of a sense of stable, mature identity that guarantees a certain autonomy. This is a key to a successful transition limiting breakdown of care and promoting "the work of the disease". The double contribution of adult and pediatric oncology provides support tailored to these psychic and societal issues. AYA teams can actively participate in this process by facilitating the acculturation of pediatric and adult care teams to the specificity of this group, thus allowing a continuum of care.

Abstract
L’Appreciative Inquiry, fondée sur ce qui fonctionne bien, sur les forces du sujet, du groupe ou du système, suscite par une méthode précise et rigoureuse une dynamique créatrice de sens. En facilitant un abord optimal de l’autre, elle permet de nourrir ces atouts et ces besoins essentiels aux soignants que sont l’empathie, la coopération et le partage, etc. Alors que les hôpitaux sont sous pression, et le soin sous tension, l’Appreciative Inquiry représente une démarche innovante de questionnement appréciatif pour faire émerger les facteurs de réussite, les ingrédients du succès, trop souvent abandonnés, et surtout le meilleur des soignants et des patients. Elle permet de (re)mettre le sens en action en facilitant l’attention sur ce qui fait vie et satisfaction pour les soignants, le sentiment de « bien soigner » notamment, précieux pas uniquement dans sa valeur esthétique ou éthique mais en tant que stimulant, protecteur de la santé au travail et d’une haute qualité des soins.

Comparison of the Abbott Alinity m and m2000 assays for the quantification of HIV-1, HCV and HBV in clinical samples. J Clin Virol 2020; 126:104331.

Abstract
BACKGROUND Viral load (VL) determination is an essential parameter of the management of patients infected with HIV, HBV or HCV. Many available molecular systems run on a "batch" mode while "random access" systems provide more flexibility. OBJECTIVES We compared the performance of HIV-1, HCV and HBV quantification assays on the recently developed Abbott Alinity m system to the m2000 RealTime assays. STUDY DESIGN Plasma specimens sent for viral load determination were prospectively tested on m2000 and Alinity m systems, according to manufacturers' instructions. Additional low and high tittered samples were used to assess reproducibility. RESULTS Assays concordance was evaluated from 180 samples for HIV-1, 122 for HBV, and 92 for HCV. A good correlation and a linear relation over the quantification range was observed for the three markers (r > 0.974). The Alinity m assays yielded higher results with a mean quantification bias of 0.22 log cp/ml for 75 HIV-1, 0.3 log IU/ml for 79 HBV, and 0.2 log for 35 HCV samples, though results were equivalent within an allowable difference of 0.3-0.4 log. Qualitative discordance was observed for 43/180 HIV results, 10/122 HBV and 7/92 HCV and involved undetectable or low-level VL. CONCLUSION The Alinity m assays have performance equivalent to m2000. Upon implementation, physicians should be aware of the relative overquantification compared to previous Abbott assays, particularly around clinical decision thresholds. With reduced turnarounds and hands-on times compared to the m2000 system, the Alinity m platform may improve significantly the laboratory workflow efficiency for the benefit of physicians and patients.

Abstract
BACKGROUND Rhabdomyosarcoma (RMS) in infants is a particular entity with various clinical presentations and outcomes. To better understand the clinical heterogeneity of RMS in infants, an integrative clinical, histological, and molecular analysis was performed. METHODS From 1989 to 2015, 37 infants aged less than 6 months with a diagnosis of RMS and archival tumor materials were identified in France. Clinical data, central pathologic review, and molecular profile including RNA sequencing were analyzed. RESULTS Nineteen patients (51%) had embryonal RMS (ERMS) (including three highly differentiated ERMS with PTCH deletion), eight (22%) had spindle cell RMS (SRMS) (three VGLL2-, one NTRK-, and two (B)RAF-fusions), six (16%) had alveolar RMS (ARMS) (all FOXO1- or PAX3-fusion), two had unclassified RMS, and two poorly differentiated RMS were retrospectively diagnosed as rhabdoid tumors (RT) with loss of INI1 expression. The two RT patients died of rapid disease progression. Five-year event-free (EFS) and overall survival (OS) for RMS were 62% (95%CI, 47-82) and 52% (95%CI, 37-72). Eleven patients (31%) relapsed and four (11%) had primary refractory disease (all ERMS). In univariate analysis, EFS and OS were only associated with histology subtype, with 100% survival of known fusion-positive SRMS. RNA cluster expression showed three main clusters: ARMS, ERMS, and "VGLL2-fusion" cluster, consisting of SRMS and ERMS. CONCLUSIONS Biopathology findings from this study support the different prognosis of infantile RMS. New fusion-positive SRMS has a very good outcome which may allow more conservative treatment in the future.

Abstract
La particularité de ces maladies sans limites est que le sujet se retrouve, de manière chronique, entre la certitude de la maladie et une immense incertitude concernant l’avenir. Si ces perspectives angoissantes ne peuvent être mises en sens afin d’envisager une vie possible autour de la maladie, le sujet peut se sentir enfermé dans une impasse existentielle face à laquelle seul le fantasme de la guérison — pourtant inaccessible la plupart du temps — apparaît comme une solution. En appelant une réponse singulière, le travail de psychothérapie favorise les possibilités de changement afin de définir son propre mode d’existence avec cette maladie.

A French national breast and thyroid cancer screening programme for survivors of childhood, adolescent and young adult (CAYA) cancers - DeNaCaPST programme. BMC Cancer 2017; 17:326.

Abstract
Background Survival of childhood, adolescent and young adult (CAYA) cancers has increased with progress in the management of the treatments and has reached more than 80% at 5 years. Nevertheless, these survivors are at great risk of second cancers and non-malignant co-morbidities in later life. DeNaCaPST is a non-interventional study whose aim is to organize a national screening for thyroid cancer and breast cancer in survivors of CAYA cancers. It will study the compliance with international recommendations, with the aim, regarding a breast screening programme, of offering for every woman living in France, at equal risk, an equal screening. Method DeNaCaPST trial is coordinated by the INSERM 1018 unit in cooperation with the LEA (French Childhood Cancer Survivor Study for Leukaemia) study’s coordinators, the long term follow up committee and the paediatric radiation committee of the SFCE (French Society of Childhood Cancers). A total of 35 centres spread across metropolitan France and la Reunion will participate. FCCSS (French Childhood Cancer Survivor Study), LEA and central registry will be interrogated to identify eligible patients. To participate, centers agreed to perform a complete “long-term follow-up consultations” according to good clinical practice and the guidelines of the SFCE (French Society of Children Cancers). Discussion As survival has greatly improved in childhood cancers, detection of therapy-related malignancies has become a priority even if new radiation techniques will lead to better protection for organs at risk. International guidelines have been put in place because of the evidence for increased lifetime risk of breast and thyroid cancer. DeNaCaPST is based on these international recommendations but it is important to recognize that they are based on expert consensus opinion and are supported by neither nonrandomized observational studies nor prospective randomized trials in this specific population. Over-diagnosis is a phenomenon inherent in any screening program and therefore such programs must be evaluated.

Abstract
The fine analysis of cell components during the generation of pluripotent cells and their comparison to bone fide human embryonic stem cells (hESCs) are valuable tools to understand their biological behavior. In this report, human mesenchymal cells (hMSCs) generated from the human ES cell line H9, were reprogrammed back to induced pluripotent state using Oct-4, Sox2, Nanog, and Lin28 transgenes. Human induced pluripotent stem cells (hIPSCs) were analyzed using electron microscopy and compared with regard to the original hESCs and the hMSCs from which they were derived. This analysis shows that hIPSCs and the original hESCs are morphologically undistinguishable but differ from the hMSCs with respect to the presence of several morphological features of undifferentiated cells at both the cytoplasmic (ribosomes, lipid droplets, glycogen, scarce reticulum) and nuclear levels (features of nuclear plasticity, presence of euchromatin, reticulated nucleoli). We show that hIPSC colonies generated this way presented epithelial aspects with specialized junctions highlighting morphological criteria of the mesenchymal–epithelial transition in cells engaged in a successful reprogramming process. Electron microscopic analysis revealed also specific morphological aspects of partially reprogrammed cells. These results highlight the valuable use of electron microscopy for a better knowledge of the morphological aspects of IPSC and cellular reprogramming.

Abstract
We report two cases of Ballantyne's syndrome which was first described in association with foeto-placental hydrops caused by rhesus isoimmunization. Our two cases occurred in association with materno-fetal parvovirus infection. Although the pathogenic mechanism remains to be fully elucidated, fluid retention and hyperplacentation are the main features. Together with these two case reports, a literature review confirmed the diverse nonimmunological etiologies associated with Ballantyne's syndrome. Clinicians should be aware of this particular presentation of hydrops fetalis resulting from a mechanism different from hypotrophic placentation because specific etiological treatment can avoid unnecessary pregnancy termination. Pre-conception counselling is also different.
