Although several cases of signet-ring cell carcinoma (SRCC) in the colorectum have been reported [1,2], there have been no reports of SRCC in the anus. The case presented here is the first reported case of primary pure SRCC of the anus. A 49-year-old man presented with anal bleeding. Colon endoscopy revealed a polyp in the anus, and polypectomy was performed The polypectomy specimen showed pure...
understanding the mechanism of tumor resistance is critical for cancer therapy. in this study, we investigated the effect of carcinoembryonic antigen (cea) overexpression on uv-and 5-fluorouracil (5-fu)-induced apoptosis and autophagy in colorectal cancer cells. we used histone deacetylase (hdac) inhibitor, nab and dna demethylating agent, 5- azacytidine (5-aza) to induce cea expression in ht29...
We investigated the diagnostic value of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) for restaging of treated uterine cervix squamous cell cancer with tumor maker elevation that was not explained by other conventional evaluation. We enrolled 32 cases who underwent PET/CT for the restaging of treated cervical cancer with tumor marker elevation that was not e...

Murine monoclonal antibodies against carcinoembryonic antigen (CEA) derived from a colonic tumor were analyzed by radioimmunoassay for reactivity with CEA and the CEA-related antigens, meconium antigen (MA) and nonspecific cross-reacting antigen. Antibody-antigen binding profiles revealed three classes of hybridomas. The Class I antibody, NP-1, recognized an epitope shared among all three antig...
The aim of the present retrospective study was to evaluate the sensitivity and specificity of fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in assessing the recurrence of colorectal cancer (CRC) with regard to carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9). 18F-FDG PET/CT was performed in 100 patients for the re-staging of CRC. Th...
BACKGROUND & AIMS The utility of measuring carcinoembryonic antigen(CEA) and cancer antigen 15-3 (CA15-3) levels in patients with breast cancer remains controversial. The present study aims to investigate the prognostic value of preoperative serum CEA and CA15-3 levels in breast cancer patients. METHODS Serum preoperative CEA and CA 15-3 concentration levels were measured in a total of 432 br...
PURPOSE The clinical significance of preoperative serum levels of carcinoembryonic antigen (CEA) and cancer antigen 15-3 (CA15-3) in breast cancer is controversial. The purpose of this study was to assess the clinical value of preoperative serum levels of CEA and CA 15-3 on the risk of axillary lymph node metastasis (ALNM) in patients with breast cancer. METHODS This retrospective study analy...
BACKGROUND Carcinoembryonic antigen (CEA) is a glycoprotein, which is present in the foetal colon, some benign conditions and different malignancies, particularly in colon adenocarcinoma. We focused this study on non-melanoma skin cancer (NMSC). NMSC is a common malignancy and it is an important source of morbidity and death in the world. In this study we evaluated whether CEA level increases i...
The diagnostic value of staining cells from serous effusion and peritoneal washing specimens with a panel of four lectins was investigated and the results compared with those achieved with polyclonal anti-carcinoembryonic antigen (anti-CEA) sera. Cell blocks from 42 pleural effusions, 25 peritoneal effusions, and 14 peritoneal washing specimens were stained with Con A (D-mannosyl, D-glucosyl), ...
