The article is being published in the respected scientific journal, Proceedings of the National Academy of Sciences (PNAS). The study includes 165 children with neuroblastoma, most of whom developed the disease before the age of five. These children have been monitored for over 20 years by two research teams led by professors Tommy Martinsson, of the Sahlgrenska Academy, and Per Kogner of Karolinska Institutet.
Neuroblastoma is a nerve cell cancer that has defects in certain chromosomes. If the tumour has a characteristic defect on chromosome 11, it is very aggressive and difficult to cure.
"We found that the children who develop this type of neuroblastoma are twice as old at the onset of the disease as children who develop other types of neuroblastoma. This type progresses more slowly and is more difficult to treat," says Helena Carén, a researcher at the Department of Clinical Genetics at the Sahlgrenska Academy.
By using the latest genetic techniques, the researchers have succeeded in analysing the DNA of tumour cells and identifying chromosomal defects, enabling the identification of sub-groups of the most aggressive neuroblastomas. The next step is to identify their weak points genetically in order to develop better treatment.
"We call this personalized medicine, because the treatment is based on the genetic profile of the patient, or in this case, of the tumour cells," says Tommy Martinsson, professor of genetics at the Department of Clinical Genetics at the Sahlgrenska Academy.
Per Kogner, professor of paediatric oncology at Karolinska Institutet, reiterates that their discovery will now allow a variety of tailor-made treatments to be developed, saving the lives of more children.
The study was carried out with the support of the Swedish Childhood Cancer Foundation and the Swedish Cancer Society.ABOUT NEUROBLASTOMA

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
