In contrast, little is known about the prognostic relevance of normal blood counts in this setting. J Clin Oncol , Procedures are seen as the main causes of pain. When larger and smaller departments are compared, in former ones the significantly preferred routes for opioid administration are i. Springer Medizin Verlag Heidelberg 3. A structured pain history and the regular scoring of pain intensity using age-adapted measuring tools are hallmarks of optimal pain control. Psychological measures are as important as drug therapy in the prophylaxis or control of pain, especially when performing invasive procedures.
Pain control is oriented toward the WHO multistep therapeutic schedule. Eight German tertiary care paediatric oncology centres prospectively documented all their in-patient pain treatment courses from June to December Pain was scored using a faces scale. A nation-wide quality improvement programme in paediatric oncology pain control.

Cancer Causes Control , 9: Knowledge of such mutations may improve the understanding of tumorigenesis, direct patient care, and enable genetic counseling of patients and families. We were unable to find reports of children or adolescents affected by an ESOS of the breast. Here, we present the case of a high-grade osteosarcoma arising in the breast of a year-old girl. The tumor was treated with breast-conserving resections and adjuvant multiagent chemotherapy, based on a regimen of doxorubicin, high-dose methotrexate, cisplatin, and ifosfamide.
At last follow-up, the patient was in first complete remission, 29 months after initial diagnosis. The aims of this analysis were to investigate features and outcome of high-grade osteosarcomas of the mobile spine. Since , 20 Cooperative Osteosarcoma Study Group patients had a diagnosis of high-grade osteosarcomas of the mobile spine and were included in this retrospective analysis of patient-, tumor- and treatment-related variables and outcome.
The median age was 29 years range Most frequent tumor sites were thoracic and lumbar spine. All but three patients had nonmetastatic disease at diagnosis. Treatment included surgery and chemotherapy for all patients, 13 were also irradiated. Eight patients failed to achieve a macroscopically complete surgical remission five local, one primary metastases, two both , six died, two are alive, both with radiotherapy.
Of 12 patients with complete remission at all sites, three had a recurrence two local, one metastases and died. The median follow-up of the 11 survivors was 8. Furthermore, nuclear immunoreactivity for beta-catenin has been described even in the absence of detectable beta-catenin mutations. This suggests that other components of the Wnt pathway may be involved in the pathogenesis of a subgroup of Wilms tumors.
Chibby C22ORF2 is a recently identified antagonistic component of the Wnt pathway that inhibits the transcriptional activity of beta-catenin. Our study addresses the question whether mutation or down-regulation of Chibby is involved in Wilms tumorigenesis.
We analysed the expression of Chibby by real time RT-PCR in Wilms tumors, but there was no significant expression difference in any group of tumors stratified according to clinical, histological and mutational criteria. Mutation analysis of a smaller cohort did not reveal any mutations of the coding sequence.
We only detected a constitutive splice variant leading to the absence of exon 4 in all Wilms tumors as well as in normal tissues. These data strongly suggest that despite its attractive function as a modulator of beta-catenin activity, Chibby is not involved in Wilms tumorigenesis. Our previous microarray screening in a large series of Wilms tumors revealed several candidate genes that are deregulated in advanced tumors and are part of the retinoic acid signaling pathway.
To investigate whether retinoic acid could be employed as a novel therapeutic agent in these tumors, we treated cultured Wilms tumor cells with different concentrations of all-trans retinoic acid ATRA and assessed gene expression changes by real-time RT-PCR as well as microarray analysis. In addition to enhanced retinoid signaling, the transforming growth factor-beta TGFbeta pathway was strongly activated by ATRA treatment of Wilms tumor cells.
Both the retinoic acid and the TGFbeta pathway mediate inhibition of cell growth. These findings represent the first molecular evidence of a potential benefit from ATRA treatment in Wilms tumors. This overexpression may be a negative feedback mechanism in tumors with uncontrolled WNT signaling. In addition, the strong representation of muscle-related genes in the expression profile of CTNNB1-mutated Wilms tumors corresponded to histologically detectable areas of myomatous cells in these tumors that displayed intense and preferential nuclear beta-catenin antibody staining.
This article contains Supplementary Material available at http: We performed cDNA microarray experiments using 63 primary Wilms tumors with the aim of detecting new candidate genes associated with malignancy grade and tumor progression. All tumors had received preoperative chemotherapy as mandated by the SIOP protocol, which sets this study apart from related approaches in the Unites States that are based on untreated samples.
The stratification of expression data according to clinical criteria allowed a rather clear distinction between different subsets of Wilms tumors. Clear-cut differences in expression patterns were discovered between relapse-free as opposed to relapsed tumors and tumors with intermediate risk as opposed to high risk histology.
Several differentially expressed genes, e. For a subset of differentially expressed genes, microarray data were confirmed by real-time RT-PCR on the original set of tumors. Interestingly, we found the retinoic acid pathway to be deregulated at different levels in advanced tumors suggesting that treatment of these tumors with retinoic acid may represent a promising novel therapeutic approach.go here

The primary objective was to determine the efficacy of a newly designed preoperative chemotherapy regimen in an attempt to improve the cure rate of children with high-risk hepatoblastoma. High risk was defined as follows: Of the patients evaluable for response Complete resection of the liver tumor could be achieved in patients In children Among the patients with initial lung metastases, Make use of the international trade fair network for your success.
