Experiences of parents with caring for their child after a cancer diagnosis.

Children and adolescents with cancer are increasingly treated and cared for at home; hospital stays are reduced to a minimum. Taking care of a sick child at home has an impact on the entire family: the sick child, the siblings, and the parents. This qualitative study examines the experiences of parents taking their child home for the first time after the diagnosis. Parents of 10 children newly diagnosed with cancer were interviewed twice around the time of the first discharge; data were analyzed using content analysis methodology. Findings illustrated parents' preparation of and experiences around their child's first discharge, the huge amount of new and changed tasks parents have to fulfill at home when caring for their child with cancer, and consequences for the parents. By providing individualized information and instruction, by having parents anticipate potential problems and solutions, and by describing available community support and integrating district nurses as well as other parents with the same experiences more frequently, health care professionals in the hospital can optimize discharge planning for these parents.

The prognostic significance of cytogenetic aberrations in childhood acute myeloid leukaemia. A study of the Swiss Paediatric Oncology Group (SPOG).

In childhood-onset acute myeloid leukaemia (AML) the clinical value of karyotypic aberrations is now acknowledged, although there is still debate concerning the prognostic significance of some events. To add to this knowledge, cytogenetic analysis was performed on a consecutive series of 84 childhood AML patients diagnosed in Switzerland. A result was obtained for all patients, with 69 (82%) showing a clonal karyotypic aberration. In the remaining 15 (18%), no karyotypic aberration was seen by either conventional or fluorescence in situ hybridisation analyses. The most frequent aberrations observed were t(11q23) (19% of all patients), t(8;21) (12%) and +8 (11%). Except for cytogenetics, no clinical parameter was shown to be significantly associated with outcome. The analysis of individual cytogenetic subgroups demonstrated that aberrations involving chromosome 16q were the strongest predictor of a good prognosis, while +8 and complex karyotypes represented the strongest predictors of a poor prognosis. It was also noteworthy that patients with the rare aberrations of del(11q) (n = 4) and t(16;21)(p11;q22) (n = 3) had a poor outcome. The results support the importance of cytogenetic analysis in childhood AML, but show that further work is required in the classification of the poor prognosis aberrations.

Characterization of karyotypic events and evolution in neuroblastoma.

BACKGROUND: Neuroblastoma (NB) is cytogenetically characterized by a number of non-random events. However, knowledge is limited concerning the timing of occurrence and inter-action of many of these events. METHODS: Karyotypic patterns were obtained from a study group of 49 NB tumors that had been analyzed by conventional cytogenetics combined with FISH and in some instances SKY. RESULTS: All chromosomes were involved in a numerical and structural aberration in at least one tumor. There was a positive correlation between the occurrence of MYCN and del(1p) and between del(1p) and 17q. Aberrations involving chromosomes X, 3, 19, and del(1p) could be considered early events, whereas those involving chromosomes 9, 13, 15, 18, 20, and 21 were often late events. CONCLUSIONS: This study suggests that the karyotypic patterns characterizing NB are complex. There are aberrations that can be grouped into early or late karyotypic events, but others, such as gain of 17q, are variable.
