Dihydropyrimidine dehydrogenase (DPD) plays a pivotal role in the metabolism of 5FU. The prognostic significance of DPD activity in peripheral blood mononuclear (PBM) cells and buccal mucosa cells with respect to toxicity was investigated in 44 patients treated with 5FU-leucovorin. Grade III/IV haematological and grade III/IV gastrointestinal toxicity were(More)
BACKGROUND Anticancer drugs are characterized by a narrow therapeutic window and significant inter-patient variability in therapeutic and toxic effects. Current body surface area (BSA)-based dosing fails to standardize systemic anticancer drug exposure and other alternative dosing strategies also have their limitations. Just as important as the initial dose(More)
UNLABELLED Hepatocellular carcinoma (HCC) is rare in the Netherlands, even though the incidence has increased quite sharply in recent years. Standard treatment options consist of surgery, orthotopic liver transplantation, radiofrequency ablation, transarterial chemoembolisation (TACE) and systemic therapy with sorafenib. The consensus-based Dutch HCC(More)
4074 Background: The PI3K/Akt/mTOR pathway, a key regulator of cellular proliferation and angiogenesis, has emerged as a contributor to hepatocarcinogenesis. Everolimus, an mTOR inhibitor, exhibits antineoplastic activity in preclinical and experimental models of HCC. Sorafenib, a multi-tyrosine kinase (including Raf) inhibitor, is the only targeted therapy(More)
Dihydropyrimidine dehydrogenase (DPD) plays a pivotal role in the metabolism of 5-fluorouracil (5FU). In patients treated with capecitabine or 5FU combined with other chemotherapeutic drugs, DPD activity in peripheral blood mononuclear cells was increased in patients experiencing grade I/II neutropenia. In contrast, decreased DPD activity proved to be(More)
e14666 Background: Despite significant changes during the last decade in our molecular knowledge on pancreatic cancer, the prognosis and management of this disease has remained unchanged. Several phase III studies have demonstrated that TKI (erlotinib) and MoAb (cetuximab) mediated inhibition of EGFR in combination with chemotherapy have limited or no(More)
