background and aims: immunohistochemical tests are one of the most important tests, which are under study to determine the prognosis of the cancers such as transitional cell carcinoma. by the time, flexible cystoscopy and urine cytology are the routine tests for following up the patients with transitional cell carcinoma, which are both operator dependent. on the other hand, cystoscopy is an inv...
Carcinoembryonic antigen (CEA) is a tumor-associated antigen targeted for the development of colorectal tumor vaccines. In this study, we developed papillomavirus pseudoviruses encoding the truncated CEA without NH2-terminal signal peptide (PV-CEA) as an oral vaccine to induce CEA-specific CTL responses. In CEA transgenic (CEA-Tg) mice orally immunized with PV-CEA, the immunologic tolerance to ...
OBJECTIVE To evaluate the diagnostic value of combination detection of serum cancer antigen 125 (CA125), carbohydrate antigen 19-9 (CA199) and carci noembryonic antigen(CEA) in patients with epithelial ovarian cancer by pooling the open published studies according to meta-analysis method. METHODS Diagnostic studies related to combination detection of serum CA125, CA199 and CEA in patients wit...
OBJECTIVES Carcinoembryonic antigen (CEA) is widely used for postoperative surveillance of colon cancer. Even if serum CEA is negative at initial surgery, it may turn positive at recurrence. We investigated the relation between serum CEA levels and the immunohistochemical staining status of CEA in the primary and resected metastatic tissues. METHODS Out of 224 patients with recurrent colon ca...
Background & Objective: One of the most prevalent types of cancer among women is breast cancer. The objective of this study is to compare the serum level of tumor marker of Carcinoembryonic Antigen (CEA), Prolactin, and oxidative marker Malondialdehyde (MDA) in patients with breast cancer and in control groups. Materials & Methods: This case control study was carried out on the people wh...
Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) are rare biliary duct neoplasms. This study investigated reasonable management strategies of cystic neoplasms in the liver. Charts of 39 BCA/BCAC patients (9 males, 30 female; median age 53.74 ± 14.50 years) who underwent surgery from January 1999 to December 2009 were reviewed retrospectively. Cyst fluid samples of 32 BCA/BCAC pat...
PURPOSE In esophageal cancer, lymph node metastases are the strongest predictor of recurrence and poor outcome. However, many node-negative patients still recur despite a potentially curative resection. This is probably the result of microscopically occult metastases missed by histological examination. In this study, we used both standard, gel-based reverse transcription-PCR (RT-PCR) and Taqman...
Antigens in human adult feces related to carcinoembryonic antigen (CEA) were analyzed with respect to their molecular masses, CEA domain compositions, and N-terminal amino acid sequences. By avoiding perchloric acid treatment, new fecal antigens related to CEA were identified. The fecal antigens revealed by Western blot were M(r) 78,000, 70,000, 60,000, 50,000, 44,000, 36,000, 33,000, and 25,00...
Diagnostic utility of E-cadherin (E-CD) and cytokeratin (CK) subtype profiling in effusion cytology was investigated, employing immunocytochemistry on cellblock sections available from 211 metastatic carcinomas (MC), 6 mesotheliomas and 73 reactive mesothelial hyperplasias (MH). E-CD and monoclonal carcinoembryonic antigen (mCEA) stained 85% (120/141) and 65% (138/211) of MC, respectively. E-CD...
Previous studies have indicated that carcinoembryonic antigen (CEA) and cancer antigen 15-3 (CA15-3) levels are both independent prognostic factors in breast cancer. However, the utility of CEA and CA15-3 levels as conventional cancer biomarkers in patients with triple-negative breast cancer (TNBC) remains controversial. The current study was performed to explore the predictive value of pre-the...
