Non-Hodgkin lymphoma (NHL) is rarely observed during infancy and data on its incidence, characteristics and outcome are scarce. The present study aimed to assess the prevalence, clinical presentation and treatment results of all infants who were diagnosed with NHL between October 1986 and December 2002 among 2084 patients treated according to the NHL-BFM (Berlin-Frankfurt-Münster) multicentre trials 86, 90 and 95. We identified 20 (1%) infants with NHL including five with T-cell lymphoblastic lymphoma (T-cell LBL), seven with precursor B-cell LBL (pB-cell LBL), two with a mature Burkitt neoplasm, five with anaplastic large cell lymphoma (ALCL) and one with peripheral T-cell lymphoma (PTCL). The PTCL patient, 3/7 pB-cell LBL and 1/5 ALCL patients relapsed. One patient each from the T-cell LBL and Burkitt lymphoma groups suffered from a second malignancy and one patient each with ALCL and Burkitt leukaemia died from treatment-related toxicity. The 5-year event-free survival rate was 53 +/- 12% for the 20 cases. This study has provided preliminary evidence that infants with NHL have a dismal prognosis and showed that infant NHL differed to lymphomas in older patients with respect to the distribution of gender, histopathologic subtypes as well as the ratio of T- to pB-cell LBL and the frequency of relapses of pB-cell LBL. 相似文献

Background
In the ALL-BFM 95 trial for treatment of acute lymphoblastic leukemia, response to a prednisone pre-phase (prednisone response) was used for risk stratification in combination with age and white blood cell count at diagnosis, response to induction therapy and specific genetic high-risk features.Design and Methods
Cytomorphological marrow response was prospectively assessed on Day 15 during induction, and its prognostic value was analyzed in 1,431 patients treated on ALL-BFM 95.Results
The 8-year probabilities of event-free survival were 86.1%, 74.5%, and 46.4% for patients with M1, M2, and M3 Day 15 marrows, respectively. Compared to prednisone response, Day 15 marrow response was superior in outcome prediction in precursor B-cell and T-cell leukemia with, however, a differential effect depending on blast lineage. Outcome was poor in T-cell leukemia patients with prednisone poor-response independent of Day 15 marrow response, whereas among patients with prednisone good-response different risk groups could be identified by Day 15 marrow response. In contrast, prednisone response lost prognostic significance in precursor B-cell leukemia when stratified by Day 15 marrow response. Age and white blood cell count retained their independent prognostic effect.Conclusions
Selective addition of Day 15 marrow response to conventional stratification criteria applied on ALL-BFM 95 (currently in use in several countries as regular chemotherapy protocol for childhood acute lymphoblastic leukemia) may significantly improve risk-adapted treatment delivery. Even though cutting-edge trial risk stratification is meanwhile dominated by minimal residual disease evaluation, an improved conventional risk assessment, as presented here, could be of great importance to countries that lack the technical and/or financial resources associated with the application of minimal residual disease analysis. 相似文献45.

Background
Since the early 1990s, three consecutive pediatric acute myeloid leukemia (AML) trials have been performed in Austria (AML-Berlin-Frankfurt-Münster (BFM) 93, AML-BFM 98, and AML-BFM 2004) in close cooperation with the international BFM study center. Herein, we review the pertinent patient characteristics, therapy, and outcome data.Patients and methods
From January 1993 to April 2013, 249 children and adolescents (193 protocol patients) diagnosed with AML were enrolled in the three BFM studies. Patients were mainly treated in one of five pediatric hematology/oncology centers distributed over Austria.Results
Many characteristics and outcome parameters were not statistically different between the three trials. Almost similar proportions of patients were stratified into two risk groups: standard risk (SR) (approximately 37?% overall) and high-risk (HR) (61?%). MLL rearrangements were found in 23?% of patients overall as the most frequent genetic aberration subtype. Complete remission (CR) was achieved by 84–95?% of patients. The most important type of event was leukemic relapse (5-year cumulative incidence 40?±?8?%, 21?±?5?%, and 39?±?6?%; p?=?0.058), with a trend to a higher rate specifically in SR patients of study AML-BFM 2004 compared with AML-BFM 98. Importantly, the frequency of death from causes other than relapse sequelae declined over the years (AML-BFM 93: 5/42 12?%, AML-BFM 98: 5/57 9?%, and AML-BFM 2004: 5/94 5?%). Altogether, event-free survival at 5 years varied insignificantly (48?±?8?%, 61?±?7?%, and 50?±?6?%; p?=?0.406). Nevertheless, survival (pSU) apparently improved from BFM 93 to subsequent studies, both overall (57?±?8?%, 75?±?6?%, and 62?±?6?%; p?=?0.046) and regarding the HR group (5-year-probability of survival (pSU) 40?±?10?%, 66?±?8?%, and 52?±?8?%; p?=?0.039).Conclusion
Treatment of pediatric AML in Austria renders survival rates in the range of international best practice. However, unambiguous statistical comparison of treatment periods is eventually hampered by small numbers and inequalities of recruitment. Hence, only internationally collaborative trials will allow developing treatment further to achieve higher cure rates with fewer events. 相似文献46.

In childhood cancer, the frequency of cancer-associated germline variants and their inheritance patterns are not thoroughly investigated. Moreover, the identification of children carrying a genetic predisposition by clinical means remains challenging. In this single-center study, we performed trio whole-exome sequencing and comprehensive clinical evaluation of a prospectively enrolled cohort of 160 children with cancer and their parents. We identified in 11/160 patients a pathogenic germline variant predisposing to cancer and a further eleven patients carried a prioritized VUS with a strong association to the cancerogenesis of the patient. Through clinical screening, 51 patients (31.3%) were identified as suspicious for an underlying cancer predisposition syndrome (CPS), but only in ten of those patients a pathogenic variant could be identified. In contrast, one patient with a classical CPS and ten patients with prioritized VUS were classified as unremarkable in the clinical work-up. Taken together, a monogenetic causative variant was detected in 13.8% of our patients using WES. Nevertheless, the still unclarified clinical suspicious cases emphasize the need to consider other genetic mechanisms including new target genes, structural variants, or polygenic interactions not previously associated with cancer predisposition.Subject terms: Oncogenesis, Paediatric cancer, Cancer genetics 相似文献

Mucormycosis in paediatric patients: demographics, risk factors and outcome of 12 contemporary cases
Däbritz J Attarbaschi A Tintelnot K Kollmar N Kremens B von Loewenich FD Schrod L Schuster F Wintergerst U Weig M Lehrnbecher T Groll AH 《Mycoses》2011,54(6):e785-e788
Mucormycosis is associated with high morbidity and mortality and is perceived as an emerging fungal infection. However, contemporary paediatric data are limited. We present a series of paediatric cases of mucormycosis reported from Germany and Austria collected within a voluntary epidemiological survey through standardised, anonymized case report forms. Twelve cases were reported between January 2004 and December 2008 (six men; mean age: 12.6 years, range: 0.1-17 years). Mucormycosis was proven in nine, and probable in three cases. Isolates included Lichtheimia (syn. Absidia pro parte, Mycocladus) (five), Rhizopus (three) and Mucor (one) species. Infection was limited to soft tissue in three cases, the lung in two cases, and an infected thrombus in one case; rhinocerebral disease was found in three cases, and pulmonary-mediastinal, pulmonary-cerebral and soft tissue-cerebral involvement in one case each. All three patients with isolated soft tissue infection were cured, whereas seven of the remaining patients died (one patient without follow-up). The overall mortality rate was 67%. While these data cannot provide conclusive data on incidence and disease burden of mucormycosis in paediatric patients, they reflect the continuing threat of these infections to immunocompromised patients and the need for improved diagnosis and management. 相似文献
