Combined therapy in children and adolescents with classical Hodgkin's lymphoma: A report from the SFCE on MDH-03 national guidelines.

Hodgkin's lymphoma (HL) in children and adolescents is highly curable, but children are at risk of long-term toxicity. The MDH-03 guidelines were established in order to decrease the burden of treatment in good-responder patients, and this report should be considered a step toward further optimization of treatment within large collaborative trials. We report the therapy and long-term outcomes of 417 children and adolescents treated according to the national guidelines, which were applied between 2003 and 2007 in France. The patients were stratified into three groups according to disease extension. Chemotherapy consisted of four cycles of VBVP (vinblastine, bleomycin, VP16, prednisone) in localized stages (G1/95 pts/23%), four cycles of COPP/ABV (cyclophosphamide, vincristine, procarbazine, prednisone, adriamycin, bleomycin, vinblastine) cycles in intermediate stages (G2/184 pts/44%) and three cycles of OPPA (vincristine, procarbazine, prednisone, adriamycin) plus three cycles of COPP in advanced stages (G3/138 pts/33%). Radiation therapy of the involved field was given to 97% of the patients, with the dose limited to 20 Gy in good responders (88%). With a median follow-up of 6.6 years, the 5-year event-free survival (EFS) and overall survival (OS) were 86.7% (83.1-89.7%) and 97% (94.5-98.1%), respectively. EFS and OS for G1, G2, and G3 were 98% and 100%, 81% and 97%, and 87% and 95%, respectively. Low-risk patients treated without alkylating agents and anthracycline had excellent outcomes and a low expected incidence of late effects. Intensification with a third OPPA cycle in high-risk group patients, including stage IV patients, allowed for very good outcomes, without increased toxicity.

Mutations in NALP12 cause hereditary periodic fever syndromes.

NALP proteins, also known as NLRPs, belong to the CATERPILLER protein family involved, like Toll-like receptors, in the recognition of microbial molecules and the subsequent activation of inflammatory and immune responses. Current advances in the function of NALPs support the recently proposed model of a disease continuum bridging autoimmune and autoinflammatory disorders. Among these diseases, hereditary periodic fevers (HPFs) are Mendelian disorders associated with sequence variations in very few genes; these variations are mostly missense mutations whose deleterious effect, which is particularly difficult to assess, is often questionable. The growing number of identified sporadic cases of periodic fever syndrome, together with the lack of discriminatory clinical criteria, has greatly hampered the identification of new disease-causing genes, a step that is, however, essential for appropriate management of these disorders. Using a candidate gene approach, we identified nonambiguous mutations in NALP12 (i.e., nonsense and splice site) in two families with periodic fever syndromes. As shown by means of functional studies, these two NALP12 mutations have a deleterious effect on NF-kappaB signaling. Overall, these data identify a group of HPFs defined by molecular defects in NALP12, opening up new ways to manage these disorders. The identification of these first NALP12 mutations in patients with autoinflammatory disorder also clearly demonstrates the crucial role of NALP12 in inflammatory signaling pathways, thereby assigning a precise function to this particular member of an emerging family of proteins whose putative biological properties are currently inferred essentially through in vitro means.

SPRED1 germline mutations caused a neurofibromatosis type 1 overlapping phenotype.

OBJECTIVE: Germline loss-of-function mutations in the SPRED1 gene have recently been identified in patients fulfilling the National Institutes of Health (NIH) diagnostic criteria for neurofibromatosis type 1 (NF1) but with no NF1 (neurofibromin 1) mutation found, suggesting a neurofibromatosis type 1-like syndrome. METHODS: 61 index cases with NF1 clinical diagnosis but no identifiable NF1 mutation were screened for SPRED1 mutation. RESULTS: We describe one known SPRED1 mutation (c.190C>T leading to p.Arg64Stop) and four novel mutations (c.637C>T leading to p.Gln213Stop, c.2T>C leading to p.Met1Thr, c.46C>T leading to p.Arg16Stop, and c.1048_1060del leading to p.Gly350fs) in five French families. Their NF1-like phenotype was characterised by a high prevalence of café-au-lait spots, freckling, learning disability, and an absence of neurofibromas and Lisch nodules in agreement with the original description. However, we did not observe Noonan-like dysmorphy. It is noteworthy that one patient with the p.Arg16Stop mutation developed a monoblastic acute leukaemia. CONCLUSIONS: In our series, SPRED1 mutations occurred with a prevalence of 0.5% in NF1 patients and in 5% of NF1 patients displaying an NF1-like phenotype. SPRED1 mutated patients did not display any specific dermatologic features that were not present in NF1 patients, except for the absence of neurofibromas that seem to be a specific clinical feature of NF1. The exact phenotypic spectrum and the putative complications of this NF1 overlapping syndrome, in particular haematological malignancies, remain to be further characterised. NIH diagnostic criteria for NF1 must be revised in view of this newly characterised Legius syndrome in order to establish a specific genetic counselling.

Age and high-dose methotrexate are associated to clinical acute encephalopathy in FRALLE 93 trial for acute lymphoblastic leukemia in children.

The objective of the study was to assess acute neurotoxicity associated with triple intrathecal therapy (TIT)+/-high-dose methotrexate (HD MTX) in children with acute lymphoblastic leukemia (ALL). 1395 children were enrolled on FRALLE 93 protocol from 1993 to 1999. Lower-risk group (LR, n=182) were randomized to weekly low-dose MTX at 25 mg/m(2)/week (LD MTX, n=81) or HD MTX at 1.5 g/m(2)/2 weeks x 6 (n=77). Intermediate-risk group (IR, n=672) were randomized to LD MTX (n=290) or HD MTX at 8 g/m(2)/2 weeks x 4 (n=316). Higher-risk group (HR, n=541) prednisone-responder patients received LD MTX and cranial radiotherapy. HR group steroid resistant cases were grafted (autologous or allogenic). TIT (MTX, cytarabine and methylprednisolone) was given every 2 weeks during 16-18 weeks and every 3 months during maintenance therapy in LR and IR patients. 52 patients (3.7%) developed neurotoxicity. Isolated seizures: n=15 (1.1%), peripheral and spinal neuropathy: n=17 (1.2%) and encephalopathy: n=20 (1.4%). Age >10 years was significantly associated with neurotoxicity (P=0.01) and use of HD MTX is associated with encephalopathy (P=0.03). Sequels are reported respectively in 60 and 33% of spinal neuropathy and encephalopathy cases. Current strategies tailoring risk of neurological sequels has to be defined.

Immune checkpoint inhibitors in MITF family translocation renal cell carcinomas and genetic correlates of exceptional responders.

BACKGROUND: Microphthalmia Transcription Factor (MITF)family translocation renal cell carcinoma (tRCC) is a rare RCC subtype harboring TFE3/TFEB translocations. The prognosis in the metastatic (m) setting is poor. Programmed death ligand-1 expression was reported in 90% of cases, prompting us to analyze the benefit of immune checkpoint inhibitors (ICI) in this population. PATIENTS AND METHODS: This multicenter retrospective study identified patients with MITF family mtRCC who had received an ICI in any of 12 referral centers in France or the USA. Response rate according to RECIST criteria, progression-free survival (PFS), and overall survival (OS) were analyzed. Genomic alterations associated with response were determined for 8 patients. RESULTS: Overall, 24 patients with metastatic disease who received an ICI as second or later line of treatment were identified. Nineteen (82.6%) of these patients had received a VEGFR inhibitor as first-line treatment, with a median PFS of 3 months (range, 1-22 months). The median PFS for patients during first ICI treatment was 2.5 months (range, 1-40 months); 4 patients experienced partial response (16,7%) and 3 (12,5%) had stable disease. Of the patients whose genomic alterations were analyzed, two patients with mutations in bromodomain-containing genes (PBRM1 and BRD8) had a clinical benefit. Resistant clones in a patient with exceptional response to ipilimumab showed loss of BRD8 mutations and increased mutational load driven by parallel evolution affecting 17 genes (median mutations per gene, 3), which were enriched mainly for O-glycan processing (29.4%, FDR = 9.7 × 10- 6). CONCLUSIONS: MITF family tRCC is an aggressive disease with similar responses to ICIs as clear-cell RCC. Mutations in bromodomain-containing genes might be associated with clinical benefit. The unexpected observation about parallel evolution of genes involved in O-glycosylation as a mechanism of resistance to ICI warrants exploration.

In a novel form of IFN-gamma receptor 1 deficiency, cell surface receptors fail to bind IFN-gamma.

Complete IFN-gamma receptor ligand-binding chain (IFNgammaR1) deficiency is a life-threatening autosomal recessive immune disorder. Affected children invariably die of mycobacterial infection, unless bone marrow transplantation is undertaken. Pathogenic IFNGR1 mutations identified to date include nonsense and splice mutations and frameshift deletions and insertions. All result in a premature stop codon upstream from the segment encoding the transmembrane domain, precluding cell surface expression of the receptors. We report herein two sporadic and two familial cases of a novel form of complete IFNgammaR1 deficiency in which normal numbers of receptors are detected at the cell surface. Two in-frame deletions and two missense IFNGR1 mutations were identified in the segment encoding the extracellular ligand-binding domain of the receptor. Eight independent IFNgammaR1-specific mAb's, including seven blocking antibodies, gave recognition patterns that differed between patients, suggesting that different epitopes were altered by the mutations. No specific binding of (125)I-IFN-gamma to cells was observed in any patient, however, and the cells failed to respond to IFN-gamma. The mutations therefore cause complete IFNgammaR1 deficiency by disrupting the IFN-gamma-binding site without affecting surface expression. The detection of surface IFNgammaR1 molecules by specific antibodies, including blocking antibodies, does not exclude a diagnosis of complete IFNgammaR1 deficiency.

Treatment of childhood acute myeloblastic leukemia: dose intensification improves outcome and maintenance therapy is of no benefit--multicenter studies of the French LAME (Leucémie Aiguë Myéloblastique Enfant) Cooperative Group.

From 1989 to 1998, 341 children were included in the French multicentric LAME (Leucémie Aiguë Myéloblastique Enfant) trials. A total of 309 children were registered in the LAME 89/91 protocol. This intensive regimen included an induction phase (mitoxantrone plus cytarabine), two consolidation courses, one containing timed-sequential high-dose cytarabine, asparaginase and amsacrine; 276 (90%) achieved a CR. The 5-year overall survival (OS) and event-free survival (EFS) were 60+/-4 and 48+/-4%, respectively. From 1997, timed-sequencing of the LAME SP induction chemotherapy led to an unacceptable frequency of consolidation delay; future improvements are unlikely to come from further increases in intensity. The role of allogenic bone-marrow transplantation from an HLA-identical sibling in CR1 was examined. The disease-free survival (DFS) was 52+/-4% for non-allografted patients and 57+/-7% for allografted patients (P=NS); a better OS for allografted patients was shown and could be related either to allo-BMT early in CR1 or to a second allo-BMT in CR2. For the complete responders after consolidation therapy, the 5-year OS was significantly better in patients randomized for no maintenance therapy (MT-) than in patients randomized for MT (77.6+/-8 vs 59+/-8%; P=0.05), while the 5-year DFS was not significantly different. Exposure to low-dose MT might contribute to clinical drug resistance and treatment failure in relapsing patients.

[How to discuss death with a dying child: a story can help?]. / Comment parler de la mort à un enfant en fin de vie: un conte peut-il être une aide?

Is it necessary - and possible - to discuss death with a child in palliative phase? How should one approach the subject? A recent Swedish study demonstrated the benefits for parents who discussed with their child his or her imminent death, and raised the question of the role nursing can play to help parents. The mother of one child treated in our unit recently wrote a story 48 hours before the child's death. The story served to broach a number of recurrent questions often raised by dying children and their families: fear of the unknown, of being replaced, the inevitability of death, grief, and fear of being forgotten... The story was given to 13 families with dying children. In order to evaluate the story's impact on families and to determine whether a document which stimulates dialogue should continue to be given to parents, we asked that they fill out a questionnaire. Fifty-five percent of parents answered, and confirmed that the story was experienced as a positive thing and helped parents to talk with their children. This study raises many questions and should be part of a global accompaniment strategy. A review of medical, general and children's literature, as well the results of our study, lead us to conclude that the medical body should lend its full support to families who wish to engage in this dialogue with their children.

Localized childhood Hodgkin's disease: response-adapted chemotherapy with etoposide, bleomycin, vinblastine, and prednisone before low-dose radiation therapy-results of the French Society of Pediatric Oncology Study MDH90.

PURPOSE: The French Society of Pediatric Oncology MDH82 study demonstrated the effectiveness of 20 Gy irradiation of involved fields after doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or mechlorethamine, vincristine, procarbazine, and prednisone/ABVD chemotherapy in children with localized Hodgkin's disease (HD). The response to primary chemotherapy was the only predictor of survival. To reduce long-term treatment complications without compromising efficacy, the MDH90 study was based on a new chemotherapy regimen devoid of both alkylating agents and anthracycline, followed by 20 Gy of radiotherapy (RT) for good responders. PATIENTS AND METHODS: From January 1990 to July 1996, 202 children were enrolled from 30 institutions. Good responders to four cycles of vinblastine, bleomycin, etoposide (VP16), and prednisone (VBVP) were given 20 Gy of RT and no further therapy. Poor responders were given vincristine, procarbazine, prednisone, and doxorubicin. After a second evaluation, good responders were given 20 Gy of RT, and poor responders were given 40 Gy of RT. RESULTS: One hundred seventy-one patients (85%) were good responders to VBVP, 27 (15%) were poor responders, and four did not respond. With a median follow-up of 74 months (range, 25 to 117 months), the 5-year overall survival rate (mean +/- SD) is 97.5% +/- 2.1%, and the event-free survival rate (mean +/- SD) is 91.1% +/- 1.8%. Significant predictors of worse event-free survival in multivariate analysis were hemoglobin < 10.5 g/L, "b" biologic class, and nodular sclerosis. CONCLUSION: These results suggest that most children with clinical stage I and II HD can be treated with chemotherapy devoid of alkylating agents and anthracycline, followed by low-dose RT.

Lymphocyte-predominant Hodgkin's lymphoma in children: therapeutic abstention after initial lymph node resection--a Study of the French Society of Pediatric Oncology.

PURPOSE: To clarify treatment strategy for lymphocyte-predominant Hodgkin's lymphoma (LPHL), the French Society of Pediatric Oncology initiated a prospective, nonrandomized study in 1988. Patients received either standard treatment for Hodgkin's lymphoma or were not treated beyond initial adenectomy. PATIENTS AND METHODS: From 1988 to 1998, 27 patients were available for study. Twenty-four patients were male, and median age was 10 years (range, 4 to 16 years). Twenty-two, two, and three patients had stage I, II, and III disease, respectively. Thirteen patients (stage I, n = 11; stage III, n = 2) received no further treatment after initial surgical adenectomy (SA). Fourteen patients received combined treatment (CT; n = 10), involved-field radiotherapy alone (n = 1), or chemotherapy alone (n = 3). The two groups were comparable for clinical status, treatment, and follow-up. RESULTS: Twenty-three of 27 patients achieved complete remission (CR). With a median follow-up time of 70 months (range, 32 to 214 months), overall survival to date is 100%, and overall event-free survival (EFS) is 69% +/- 10% (SA, 42% +/- 16%; CT, 90% +/- 8.6%; P <.04). If we considered only the patients in CR after initial surgery (n = 12), EFS was no longer significantly different between the two groups. Patients with residual mass after initial surgery (n = 15) had worse EFS if they did not receive complementary treatment (P <.05). CONCLUSION: Although based on a small number of patients, our study showed that (1). no further therapy is a valid therapeutic approach in LPHL patient in CR after initial lymph node resection, and (2). complementary treatment diminishes relapse frequency but has no impact on survival.

Use of recombinant human granulocyte colony-stimulating factor to increase chemotherapy dose-intensity: a randomized trial in very high-risk childhood acute lymphoblastic leukemia.

PURPOSE: To determine whether the use of a recombinant human granulocyte colony-stimulating factor ([G-CSF] lenogastrim) can increase the chemotherapy dose-intensity (CDI) delivered during consolidation chemotherapy of childhood acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS: Sixty-seven children with very high-risk ALL were randomized (slow early response to therapy, 55 patients; translocation t(9;22) or t(4;11), 12 patients). Consolidation consisted of six courses of chemotherapy; the first, third, and fifth courses were a combination of high-dose cytarabine, etoposide, and dexamethasone (R3), whereas the second, fourth, and sixth courses included vincristine, prednisone, cyclophosphamide, doxorubicin, and methotrexate (COPADM). G-CSF was given after each course, and the next scheduled course was started as soon as neutrophil count was > 1 x 10(9)/L and platelet count was > 100 x 10(9)/L. CDI was calculated using the interval from day 1 of the first course to hematologic recovery after the fifth course (100% CDI = 105-day interval). RESULTS: CDI was significantly increased in the G-CSF group compared with the non-G-CSF group (mean +/- 95% confidence interval, 105 +/- 5% v 91 +/- 4%; P <.001). This higher intensity was a result of shorter post-R3 intervals in the G-CSF group, whereas the post-COPADM intervals were not statistically reduced. After the R3 courses, the number of days with fever and intravenous antibiotics and duration of hospitalization were significantly decreased by G-CSF, whereas reductions observed after COPADM were not statistically significant. Duration of granulocytopenia was reduced in the G-CSF group, but thrombocytopenia was prolonged, and the number of platelet transfusions was increased. Finally, the 3-year probability of event-free survival was not different between the two groups. CONCLUSION: G-CSF can increase CDI in high-risk childhood ALL. Its effects depend on the chemotherapy regimen given before G-CSF administration. In our study, a higher CDI did not improve disease control.

Multi-centre pilot study of 2-chlorodeoxyadenosine and cytosine arabinoside combined chemotherapy in refractory Langerhans cell histiocytosis with haematological dysfunction.

The aim of this study was to assess the efficacy and adverse effects of 2-chlorodeoxyadenosine (2-CdA) and cytosine arabinoside (Ara-C) in children with refractory Langerhans cell histiocytosis (LCH) and haematopoietic dysfunction. Ten patients, with a median age at diagnosis of 0.5 years, were enrolled in this study. Treatment comprised at least two courses of Ara-C (1000 mg/m(2)/d) and 2-CdA (9 mg/m(2)/d) administered for 5d every 4 weeks; subsequent median follow-up was 2.8 years (range 0.03-6.4 years). Among the 7 patients who received at least two courses of therapy, disease activity decreased in 6 patients, and control of disease was achieved in all patients after a median delay of 5.5 months. All patients suffered World Health Organisation (WHO) grade 4 haematological toxicity. Two septic deaths occurred shortly after administration of the first course of 2-CdA/Ara-C; a third patient was withdrawn from the trial after the first course and subsequently died following haematopoietic stem cell transplantation. This series is small, but we conclude that 2-CdA and Ara-C combined chemotherapy probably has major activity in childhood refractory Langerhans cell histiocytosis.

Detection of recipient cells after non T-cell depleted bone marrow transplantation for leukemia by PCR amplification of minisatellites or of a Y chromosome marker has a different prognostic value.

We used polymerase chain reaction amplification of minisatellite sequences (33.6.3, MS51, YNZ22) and of a Y chromosome-specific sequence (DYZ1) to document prospectively chimerism in 23 leukemia patients grafted with non T-cell depleted marrows from HLA-identical sibling donors. Twenty-two patients had a complete hematopoietic chimerism (within the sensitivity limit of the method used: 1%) early (about 1 month) after transplantation and one had detectable residual host cells (partial chimerism). These cells were still present after 8 months, and this patient relapsed 16 months after transplantation. Two patients with early complete chimerism relapsed 16 and 17 months after transplantation. Seven patients died from toxicity or infections and 13 are in clinical remission with a follow-up of 16 to 48 months. Nine male patients grafted with the marrow from a female donor were also studied by amplification of the DYZ1 marker (0.01% sensitivity). In all nine cases, residual male nucleated cells were detected early and up to 1 year after transplantation. These results suggest that the detection of persistent residual recipient cells above a 1% level might be predictive of relapse but that the detection of such cells in a 0.01-1% range is probably unrelated to relapse and does not seem to influence the outcome of the transplantation procedure.

Are basic fibroblast growth factor and vascular endothelial growth factor prognostic indicators in pediatric patients with malignant solid tumors?

Angiogenesis plays an important role in the growth, progression, and metastasis of solid tumors. Among angiogenic factors, basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) appear to be useful markers in adults with cancer. The aim of this pilot study was to determine the levels of VEGF in serum and bFGF in serum and urine of children with solid tumor at diagnosis (as measured by ELISA), and to investigate whether these parameters provide prognostic information. Forty consecutive patients with different types of cancer were prospectively included in this study. Median values of all studied angiogenic factors were higher in patients than in controls (n = 40), and the differences were statistically significant for bFGF in serum and urine: 10 versus 3 pg/ml (P = 0.0004) and 6406 versus 0 pg/g of creatinine (P < 0.0001), respectively. Among patients, median serum values of bFGF and VEGF were higher in children with metastatic disease (n = 14) than in those with localized disease (n = 26). The difference was statistically significant for serum bFGF: 17.5 versus 6 pg/ml (P = 0.02). Serum angiogenic factor levels correlated with outcome. The estimated event-free survival at 3 years was 79% for patients with normal bFGF values (n = 13) versus 42% (n = 26; P = 0.02) for those with high levels, and 71% in case of normal VEGF values (n = 20) versus 38% (n = 19; P = 0.04) for those with high levels. No benefit of normal urinary bFGF values was observed. Our results provide a rationale for exploring the clinical interest of bFGF and VEGF measurements in body fluids of a larger group of children with cancer.

[Prenatal ultrasound diagnosis of neuroblastoma]. / Neuroblastomes de diagnostic échographique anténatal.

With the progress of foetal ultrasonography, diagnosis of foetal tumors can be made before birth. We report five cases of prenatally detected neuroblastoma of the adrenal glands. Diagnosis was made during the third trimester in all cases. At birth no clinical sign related to the tumor was present, and urinary catecholamines were within normal ranges. On ultrasound scans the tumor was cystic in 1 case, solid in 2 cases and of mixed echogenicity in 2 cases. All children were operated on without pre or postoperative chemotherapy. In each setting the tumor was a stage I neuroblastoma according to the Evans classification. All children are alive and disease-free with a follow-up of 32 months at 14 years.

[Disseminated fusarium infection in two neutropenic children]. / Fusariose disséminée chez deux enfants neutropéniques.

UNLABELLED: Disseminated fusariosis in children is a rare and serious fungal infection, that occurs especially in neutropenic immunosuppressed patients, treated for malignant hemopathy, or bone marrow transplant recipient. Treatment is difficult and mortality is estimated between 50 and 70% in adult patients. CASE REPORT 1: A ten-year-old boy, treated for an acute lymphoblastic leukemia in second relapse, presented a disseminated fusarium spp infection, that occurred during neutropenia. He died due to fusariosis infection in spite of amphotericin B treatment. CASE REPORT 2: A ten-year-old neutropenic girl, treated for an acute myeloïd leukemia, presented disseminated fusariosis, uncontrolled by amphotericin B. Recovery was observed after voriconazole introduction and resolution of neutropenia. Ten months later, she presented a leukemia's relapse, treated by new intensive chemotherapy with secondary prophylaxis by voriconazole, without fusariosis's recurrence. CONCLUSION: Voriconazole, a new triazole agent, seems to be an alternative antifungal agent to amphotericin B for disseminated fusarium infection, either at the acute phase or for secondary prophylaxis.

[Quality of life of adolescents surviving childhood acute lymphoblastic leukemia]. / Vécu des adolescents guéris d'une leucémie aiguë lymphoblastique.

PURPOSE: To evaluate how adolescents and young adults cured of acute lymphoblastic leukemia (ALL) treated during childhood have integrated the disease, and possible death related to cancer. Particularly, we have focused on experiences related to diagnosis announcement, hospitalisation and treatments and consequences on their social, psychological and somatic behaviour. PATIENTS: Forty-one patients cured of ALL have been enrolled in the study and answered one interview with clinical psychologist or research nurse. RESULTS: Although 60% of the patients argued that they think rarely of their disease, 10% thought about it every day. Traumatic evidence was detectable in most of them. Physical pain was the most reported stress, mainly during hospitalisation (93%), as well as psychological suffering (83%). Afterwards, the mostly often-reported stress was psychological pain (61%). Sixty-six percent declared that they still experience psychological and health consequences at the time of the interview, in some cases reported as a handicap in their life. In 83% of the cases they considered themselves as cured, nevertheless fear of relapse persisted in 1/3. Ninety percent said they have a pleasant life, 56% did not like to talk about leukaemia and 70% thought they could have died. For 85%, disease has been the most important event of their life and 75% testify to repercussions of the disease on their family (family relationship changes, overprotection, siblings difficulties). CONCLUSION: Most of these patients declared to be 'as the others' and developed life projects, but overcoming the pain experience of the disease remained difficult. This study emphasized the need for long-term continuous information and reinforces the importance of addressing treatment psychological and physical pain mainly after the initial hospitalisation period.

[Multidisciplinarity, education, and training in pediatric oncology-hematology]. / Multidisciplinarité et formation des spécialistes à l'oncologie et à l'hématologie maligne pédiatrique.

INTRODUCTION: According to the European Society of Pediatric Oncology (SIOPE) standard of care guidelines, high-quality care of children and adolescents with cancer needs to be delivered by well-trained multidisciplinary teams in specialist centers working with designated shared-care local centers in a so-called hub-and-spoke model. The Diplôme Inter-Universitaire d'Oncologie Pédiatrique (DIUOP) is the only European training program in pediatric oncology in French for all physicians involved in care of patients with pediatric malignancies. In agreement with the SIOPE syllabus, the DIUOP is composed of training courses (120h), on-site practical training in a specialist center, and a research project to be defended before an examining board. METHOD: All graduates received a questionnaire to describe their current professional position. A comprehensive PubMed analysis retrieved all papers published form DIUOP research projects. RESULTS: From 2000 to 2011, 290 physicians were trained: 242 pediatricians, 21 surgeons, and 19 radiation therapists. Eight had another specialty including imaging, hematology, and pathology. Ninety-two were initially trained outside of France: 50% in Europe (mainly in Italy, Belgium, and Switzerland), 42% in Africa and the Middle East, and 8% in South America. Of the 266 graduates, 74% answered the questionnaire, and 90% of them take care of children and adolescents with cancer. Sixty-nine articles, i.e., one out of four research projects, were published in 34 journals with a median impact factor of 3.5 (0-22.6), 85% in English. CONCLUSION: DIUOP is the only French-speaking European education program providing a high-quality, professionalizing, and comprehensive multidisciplinary training program for French and international specialists taking care of children and adolescents with cancer.
