now an acknowledged member of immunoglobulin superfamily [2], with a role as an …

Colorectal cancer (CRC) is the third most common cancer worldwide. A diagnosis at early
stages with enhanced screening methods is vital as metastases and recurrences increase …

We assessed the prognostic significance of preoperative serum carcinoembryonic antigen
(CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 242 (CA242) levels in …

Results The Dukes' stages (log-rank chi-square= 231.9; P< 0.0001) represent the best
prognostic factor besides the preoperative values of CA 19-9 (log-rank chi-square= 162.5) …

Background: The purpose of this study was to evaluate the significance of the combination of
the carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels as a …

Results In univariate analysis, differentiation (P< 0.001), depth of invasion (P< 0.001),
number of lymph node metastases (P< 0.001), and elevated levels of CEA (P< 0.001) and …

Results The Dukes' stages (log-rank chi-square= 231.9; p< 0.0001) represent the best

BACKGROUND: Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9)
are the most common tumor markers for colorectal cancer. The aim of this study was to …

Aims: This study evaluated the prognostic value of the preoperative CEA and CA 19-9 levels
on the survival time and TNM staging in patients with colorectal cancer. Methodology: We …
