BACKGROUND Patients with well-differentiated thyroid cancer (WDTC) regularly have an excellent prognosis. However, tumor recurrence either involving the thyroid bed or the regional lymph nodes, or both, can be associated with significant morbidity and even mortality. The aim of the follow-up after primary surgery is to detect recurrent disease at its(More)
Tumour cell adhesion within the microvasculature of host organs, its stabilisation and cell invasion into the host organs, appear to be important steps in the formation of distant metastases. Intravital fluorescence-video microscopy was used to investigate the early steps in metastasis formation of colon carcinoma cells within the liver, which is the main(More)
Recent studies have demonstrated that the chemokine receptor CXCR4 plays a crucial role in organ-specific metastasis formation. Although a variety of studies showed the expression of chemokine receptors, in particular, CXCR4, by gastrointestinal tumors, the precise mechanisms of chemokine receptor-mediated homing of cancer cells to specific sites of(More)
Tumor cells can show different malignant properties regarding their ability for organ-specific metastasis formation. Their adhesive and invasive characteristics mediated by various cell adhesion molecules appear to be crucial for this process. Using intravital fluorescence microscopy, we analyzed the adhesive and invasive interactions of circulating human(More)
To form clinically evident metastases--the main cause of death in cancer patients--, tumor cells (TC) must complete a highly complex series of steps called the metastatic cascade, including local invasiveness, intravasation, circulation, adhesion and extravasation, survival, proliferation and angiogenesis. Since failure of any one of these steps results in(More)
Adhesive and invasive characteristics appear to be crucial for organ-specific metastasis formation. Using intravital microscopy we investigated the relation between the metastatic potential of colon carcinoma cells and their adhesive and invasive behavior during early steps of metastasis within microvasculatures of rat liver, lung, intestine, skin, muscle,(More)
Metastatic lesions are the leading cause of death among cancer patients. These lesions usually originate from clonal proliferation of single tumor cells dispersed from the primary tumor into the circulation which finally arrest in the capillary bed of distant organs. The microenvironment within the circulation of potential metastatic target organs provides(More)
A safety margin of ≥10 mm is generally accepted in surgery for colorectal metastases. It is reasonable that modern methods of liver parenchyma dissection may allow for a reduction in this distance. A total of 333 patients were included in a multicenter trial after resection of colorectal liver metastases. Dissection of the liver had been performed with a(More)
OBJECTIVE Detection of abdominal injury is a very important component in trauma management, so a precise assessment of liver and spleen injuries including their severity degree is necessary. There is a good case to believe that in emergency situations the radiologists' performance may profit from a systematic approach using established scoring systems.(More)
In the case of hepatocellular carcinoma (HCC), underlying liver pathology may not only determine the feasibility of surgery but may also affect the postsurgical outcome. We report our experience after curative liver resection for HCC in patients with normal liver, liver fibrosis, and liver cirrhosis. A total of 72 patients after liver resection with(More)
