PURPOSE To determine the expression of the chemokine receptors CXCR4 and CCR7 on human uveal melanoma cells and their metastases and the effect of liver-borne factors on the chemotactic responses of uveal melanoma cells. METHODS Four human uveal melanoma cell lines and three cell lines of uveal melanoma metastases were examined by RT-PCR and flow cytometry for their constitutive expression of...
BACKGROUND Hepatic metastases of neuroendocrine tumors (NETs) are considered a major prognostic factor associated with significantly reduced survival compared to patients without liver metastases. Several surgical and nonsurgical strategies are present to treat resectable and nonresectable liver metastases, some of which have the potential to cure liver mestatases. OBJECTIVE The aims of the f...
A 39 years old male patient with a history of an unresectable thymoma and synchronous liver metastases was referred tor our position. The patient had been originally treated with systemic chemotherapy followed by imatinib (Glivec) and sunitinib (Sutent). Since the therapeutic response was unsatisfactory, a gallium-68 ((68)Ga)-Dotatoc-positron emission tomography (PET) was performed and demonstr...
BACKGROUND The significance of hepatic resection for liver metastasis after gastric cancer is not well established. This study aimed to evaluate the effect of hepatic resection in such patients. PATIENTS AND METHODS A retrospective analysis was performed on the outcome of 63 patients with liver metastases without other non-curative factors of gastric cancer who underwent gastrectomy with or w...
Synchronous or metachronous liver metastases occur in up to one-third of patients with colorectal cancer and are associated with a poor prognosis. Many evidences have shown that surgical resection can be curative, with 5-year survival rates ranging from 37% to 50%, but many patients are ineligible for surgery because of multiple liver lesions, bilobar distribution of liver metastases, or the pr...
Introduction: Liver metastases of neuroendocrine tumors (NET) show MRI-characteristics, which differ from most other liver metastases; i.e. they are hypervascular in the hepatic arterial dominant phase (1;2). The response of the metastases to treatment is not sufficiently reflected by the RECIST criteria. However, metastases of NET rather show characteristic changes to treatment, like central n...
It has been reported that suppression of protein kinase N3 (PKN3) expression in vascular and lymphatic endothelial cells results in the inhibition of tumor progression and lymph node metastasis formation. The present study investigated whether combination therapy of small interfering RNA (siRNA) against PKN3 and doxorubicin (DXR) could increase therapeutic efficacy against liver and lung metast...
Metachronous CRCLM should be evaluated by multidisciplinary oncologic consilium. Diagnostic evaluation must be completed by dinamic CT or MR of the liver. In the case of a small number of metastases, operation could be performed immediately. In such cases, neoadjuvant therapy could be recomended because of decreasing recurrence rates, slight increase of the overall survival rate and to evaluate...
INTRODUCTION Due to advanced chemotherapy regimens, patients presenting with residual liver metastases of colorectal cancer (CRC) has increased. Surgery of residual metastases enhances overall survival, but surgical resection is often limited. Less invasive techniques have been invented to enhance local disease control. We investigated in a selected patient cohort local control of liver metasta...
