SUMMARY

Targeted next generation sequencing is a complex procedure including the ‘wet bench’ and ‘dry bench’ parts. Both parts are composed of many steps for which optimal assay conditions and settings must be determined.

The aim of these guidelines is to provide generic, platform independent, recommendations for targeted next generation sequencing tests to detect acquired somatic mutations in DNA, in (haemato)-oncology that are complementary to the ISO 15189 norm (medical laboratories) in order to:

  1. facilitate the implementation of the required quality metrics for the detection of somatic variants by next generation sequencing in oncology and haemato-oncology in the Belgian laboratories,
  2. harmonise test validation and verification,
  3. harmonise clinical interpretation and reporting of variants and,
  4. assure and maintain optimal test performance by establishing procedures and modalities for internal quality control and external quality assessments.

Transforming growth factor β: friend or foe in disguise?

BJMO - volume 6, issue 6, december 2012

TGF-β is a major regulator and driver of many biological processes, but its main function is inhibition of cell cycle progression and apoptosis, thus establishing a tumour-protective effect in early stages of malignant transformation. However, mutational alterations can occur at different levels of the TGF-β signaling cascade. These mutations, combined with the significant influence of the tumour microenvironment on this cascade, can cause a functional shift of TGF-β from being a tumour suppressor to becoming a tumour promoter in more advanced cancers. In most tumours this will ultimately contribute to the formation of metastatic laesions. In the clinical setting of breast cancer, TGF-β plays a significant role in the acquisition of endocrine resistance. Thus, therapeutic intervention of TGF-β signaling might deliver significant benefits in the treatment of cancer. (BELG J MED ONCOL 2012;6:188–193)
