neuroendocrine cells are of the peptide and amine secreting cells and because of endodermal origin, exist in respiratory and gastrointestinal system. the report confirms the presence of a tumor using immunohistochemical methods. a hepatic mass was detected in a 10-year-old male mixed–breed dog which was referred with clinical history of frequent vomiting, anorexia, lethargy and syncope. biochem...
The prediction of peritoneal recurrence in gastric cancer patients is extremely important in preventing an unfavorable prognosis. In this prospective study, we examined the usefulness of the carcinoembryonic antigen (CEA) and cytokeratin 20 (CK20) mRNA detection in peritoneal washes as a prophylactic tool for peritoneal recurrence. Peritoneal washes were obtained from 164 patients with gastric ...
BACKGROUND Carcinoembryonic antigen (CEA) and cytokeratin 20 (CK20) are established tumour markers and the CEA pre-operative levels in serum have prognostic value. The aim of this study was to verify the usefulness of the estimation of CEA and CK20 gene expressions in tissues of colorectal cancers and their liver metastases. PATIENTS AND METHODS Two hundred and twenty-two specimens of colorec...
OBJECTIVE To establish a sensitive method for the early detection of circulating tumor cells (CTCs) in peripheral blood (PB) of colorectal cancer (CRC) patients. METHODS PB samples were collected from 156 CRC patients, 40 benign colorectal disease patients, 40 healthy individuals and 45 patients with other solid tumors. The combination of negative and positive immunomagnetic bead method was u...
The clinical significance of isolated tumor cells (ITC) circulating in the blood of patients with colorectal cancer is unclear. In this study, we investigated the relationship between the presence of ITC that express carcinoembryonic antigen (CEA) and/or cytokeratin 20 (CK20) transcripts in the blood and the clinicopathological findings and prognosis using the quantitative real-time reverse tra...
An immunohistochemical study was performed with the use of Dako’s EnVision method, as previously described [6, 7]. The results are shown in Table 1. The morules were positive for pancytokeratins (AE1/3 and CAM5.2), cytokeratin (CK) 34BE12, CK5/6, CK8, CK19, Ki-67 (labeling=1%) and p63, but were negative for CK7, CK14, CK20, p53, vimentin, CA125, S100 protein, desmin, CEA, α-smooth muscle antige...
The diagnosis of Krukenberg tumors, as in other types of metastatic tumors of unknown primary origin, can often be a challenge for clinicians. In many cases, traditional diagnostic methods are insufficient, requiring immunohistochemistry analysis for identifying the origin of metastatic tumors. In our study, we examined a total of 34 female patients with Krukenberg tumors with different sites o...
CONTEXT Although identification of the primary tumor in patients with metastatic adenocarcinoma has a profound clinical impact, diagnosing the organ of origin is frequently difficult. Because none of the individual immunohistochemical markers used for tissue identification are both site specific and site sensitive, multiple markers are needed to improve the prediction of primary sites. OBJECT...
OBJECTIVE To assess the effect of hyperthermic intraperitoneal chemotherapy (HIPEC) to eradicate intraperitoneal free cancer cells and to explore the feasibility of cytological cure for peritoneal carcinomatosis (PC). METHODS The peritoneal lavage fluid (or ascites) from 50 PC patients was collected before and after intraoperative HIPEC, respectively, for conventional cytology test, and conve...
The objectives of this study were to assess whether the use of two reverse transcription-PCR (RT-PCR) cDNA assays and multiple blood sampling increased circulating tumor cell detection in colorectal cancer patients. Systemic blood was sampled three times at 1-min intervals in 100 colorectal cancer patients (50 primary tumors only and 50 liver metastases), and in 70 control patients without know...
