The insulin-like growth factor type 1 receptor (IGF1R) is involved in progression of breast cancer and resistance to systemic treatment. Targeting IGF1R signaling may, therefore, be beneficial in systemic treatment. We report the effect of IGF1R expression on prognosis in invasive ductal breast carcinoma (IDC), the most common type of breast cancer.(More)
AIM Insulin-like growth factor-1 receptor (IGF1R) is a tyrosine kinase receptor mediating cell growth and survival of cancer cells. We studied responses to IGF1R tyrosine kinase inhibitor NVP-AEW541 combined with conventional systemic drugs in breast cancer cell lines of different clinical subtype. MATERIALS AND METHODS Sensitivity to NVP-AEW541, single(More)
The importance of insulin-like growth factor 1 receptor (IGF-1R) signalling in malignant behaviour of tumour cells is well established. Currently, development of drugs targeting the IGF-1R as anticancer treatment is emerging. Several IGF-1R targeting strategies are being investigated in phases I and II clinical trials. Interactions of IGF-1R with insulin(More)
High circulating insulin-like growth factor 1 (IGF-1) levels are firmly established as a risk factor for developing breast cancer, especially estrogen positive tumors. The effect of circulating IGF-1 on prognosis once a tumor is established is unknown. The authors explored the effect of IGF-1 blood levels and of it's main binding protein, IGFBP-3, on(More)
Perihilar cholangiocarcinoma presents at the biliary and vascular junction of the hepatic hilum with a tendency to extend longitudinally into segmental bile ducts. Most patients show metastatic or unresectable disease at time of presentation or surgical exploration. In patients eligible for surgical resection, challenges are to achieve negative bile duct(More)
