The phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin-pathway (PI3K/AKT/mTOR-pathway) plays a role in the regulation of cell proliferation, cell survival, angiogenesis and resistance to anti-tumor treatments. In many tumor types the PI3K/AKT/mTOR-pathway is found activated through several different underlying mechanisms. Since(More)
PURPOSE The somatostatin analogue [DOTA0, Tyr3]octreotide (DOTATOC) has previously been labeled with low linear energy transfer (LET) beta-emitters, such as 177Lu or 90Y, for tumor therapy. In this study, DOTATOC labeled with the high-LET alpha-emitter, 213Bi, was evaluated. EXPERIMENTAL DESIGN The radiolabeling, stability, biodistribution, toxicity,(More)
Delayed chemotherapy-induced nausea and vomiting (CINV) remains an important adverse effect of moderately emetogenic chemotherapy not containing anthracyclines and cyclophosphamide (non-AC MEC). In this review, we summarize current literature to update recommendations for delayed CINV prophylaxis after non-AC MEC. We conducted a systematic search in PubMed(More)
To better understand the mechanisms underlying (in)sensitivity of tumors to anticancer drugs, assessing intra-tumor drug pharmacokinetics (PKs) could be important. We explored the feasibility of microdialysis in tumor tissue for multiple days in a clinical setting, using carboplatin as model drug. Plasma and microdialysate samples from tumor and adipose(More)
BACKGROUND Omeprazole is one of the most prescribed medications worldwide and within the class of proton pump inhibitors, it is most frequently associated with drug interactions. In vitro studies have shown that omeprazole can alter the function of metabolic enzymes and transporters that are involved in the metabolism of irinotecan, such as uridine(More)
PURPOSE Statins have for long been considered to play a potential role in anticancer treatment based upon their ability to inhibit the mevalonate synthesis pathway. This randomised phase II trial compared the efficacy and safety of pravastatin added to epirubicin, cisplatin and capecitabine (ECC versus ECC+P) in patients with advanced gastric carcinoma. (More)
INTRODUCTION The number of older patients with cancer is increasing. Standard clinical evaluation of these patients may not be sufficient to determine individual treatment strategies and therefore Geriatric Assessment (GA) may be of clinical value. In this review, we summarize current literature that is available on GA in elderly patients with solid(More)
Cross-sex hormone treatment of transsexual people may be associated with the induction and growth stimulation of hormone-related malignancies. We report here five cases of breast cancer, three in female-to-male (FtoM) transsexual subjects and two in male-to-female (MtoF) transsexual subjects. In the general population the incidence of breast cancer(More)
Response to anticancer therapy is believed to be directly related to the concentration of the anticancer drug in the tumor itself. Assessment of intra-tumor drug pharmacokinetics can be helpful to gain more insight into mechanisms involved in the (in)sensitivity of tumors to anticancer therapy. We explored the pharmacokinetics of 5-fluorouracil in both(More)
BACKGROUND JNJ-26483327 is an oral, potent, multi-targeted tyrosine kinase inhibitor, inhibiting kinases of epidermal growth factor receptor (EGFR)-1, -2 and -4, rearranged during transfection (RET) receptor, vascular endothelial growth factor receptor (VEGFR)-3 and Src family (Lyn, Fyn, Yes) at low nanomolar concentrations. This phase I, accelerated(More)
