Individualized medication with separately customized treatments is ending up being increasingly more a truth in cancer. This needs an exact check out the hereditary product of growths, a molecular diagnostic growth profile. A research study group from the German Network for Personalized Medicine (DNPM) has actually taped the quality requirements according to which genome analyses are performed in Germany.
Their research study is released in the European Journal of CancerThe information is a requirement for incorporating gene sequencing into regular care. The working group led by Professor Albrecht Stenzinger from the Medical Faculty of Heidelberg University supervised of the job.
Barely any other medical field is altering as quickly as cancer medication. This uses to understanding about growth illness along with the advancement of brand-new treatments. In current years, research study has actually moved a growing number of to the molecular biological level.
Progressively, the hereditary qualities of growths are being analyzed, a few of which appropriate targets for targeted treatments. The vision for the future is to produce a molecular biological profile for each private growth, which can be utilized as a basis for the treatment idea.
It is now possible to “read out” specific genes, a choice of genes and even the whole hereditary product of an individual. Gene sequencing, panel sequencing, exome and genome sequencing are the technical terms. The hereditary product– DNA (deoxyribonucleic acid)– is encrypted details that utilizes just a couple of letters.
Molecular pathologists such as Prof. Stenzinger, head of the research study and head of the Molecular Pathology Center at the Pathology Institute of the UKHD, have the ability to check out and comprehend this code much better and much better. To do this, the growth sample is very first processed, broken down into its foundation together with its hereditary info and after that examined.
The resulting “letter salad” is then arranged and structured by bioinformaticians with the aid of high-performance computer systems. The outcome is a legible book including the hereditary info of the particular client, or more specifically, their growth.
A quality-assured treatment is important here. This is the only method to ensure that the sequencing of one and the exact same sample in 2 various institutes results in a similar outcome and for that reason likewise to the suitable treatment. Which technique is utilized to series the hereditary product and how excellent the outcome of the analysis is has actually not yet been methodically taped in Germany.
A minimum of not as far as the sequencing of an especially pertinent part of the genome, the so-called exon, is worried. Exons are all areas of hereditary details which contain plans (codes) for proteins. The whole genome is far more substantial.
