    • Dihydropyrimidine dehydrogenase (DPD) is the initial enzyme acting in the catabolism of the widely used antineoplastic agent 5-fluorouracil (5FU). DPD deficiency is known to cause a potentially lethal toxicity following administration of 5FU. Here, we report novel genetic mechanisms underlying DPD deficiency in patients presenting with grade III/IV 5FU-associated toxicity. In one patient a genomic DPYD deletion of exons 21-23 was observed. In five patients a deep intronic mutation c.1129-5923C>G was identified creating a cryptic splice donor site. As a consequence, a 44 bp fragment corresponding to nucleotides c.1129-5967 to c.1129-5924 of intron 10 was inserted in the mature DPD mRNA. The deleterious c.1129-5923C>G mutation proved to be in cis with three intronic polymorphisms (c.483 + 18G>A, c.959-51T>G, c.680 + 139G>A) and the synonymous mutation c.1236G>A of a previously identified haplotype. Retrospective analysis of 203 cancer patients showed that the c.1129-5923C>G mutation was significantly enriched in patients with severe 5FU-associated toxicity (9.1%) compared to patients without toxicity (2.2%). In addition, a high prevalence was observed for the c.1129-5923C>G mutation in the normal Dutch (2.6%) and German (3.3%) population. Our study demonstrates that a genomic deletion affecting DPYD and a deep intronic mutation affecting pre-mRNA splicing can cause severe 5FU-associated toxicity. We conclude that screening for DPD deficiency should include a search for genomic rearrangements and aberrant splicing.

  • Molecularly targeted therapies for colorectal cancer: Strategies for implementing translational research in clinical trials
  • 2010
  • In: CURRENT OPINION IN MOLECULAR THERAPEUTICS. - : Thomson Scientific. - 1464-8431. ; 12:6, s. 703-711
  • Research review (peer-reviewed)abstract
    • Few breakthroughs in preclinical research have translated into meaningful benefits, either in clinical terms or quality of life, for patients with advanced colorectal cancer, despite important preclinical discoveries regarding aberrant biological pathways associated with disease development and progression. The many reasons for the slow progress are diverse, ranging from the failure to codevelop biomarkers and targeted therapies, the regulatory burdens imposed on academic investigators, and the failure to collect serial tumor biopsies during clinical trials. This review discusses promising translational research that could help reduce the disparity between preclinical discovery and patient benefit, and advocate the concentration of efforts and resources on the most promising therapeutic targets in colorectal cancer, such as EGFR, VEGF and Fc gamma receptor.
