Colorectal carcinoma liver metastases: clinical significance of preoperative measurement of serum carcinoembryonic antigen and carbohydrate antigen 19-9 levels

The clinical significance of preoperative levels of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) was evaluated in patients with colorectal carcinoma liver metastases. Preoperative serum CEA and CA 19-9 levels, the number and size of liver metastases, and survival data were analyzed retrospectively in 73 patients. Using the cutoff level of 5 ng/ml for CEA and 37 U/ml for CA 19-9, the positivity of these for detecting metastatic deposits were 81% and 56%, respectively. CEA level was correlated with the number (P = 0.0081) and size (P = 0.013) of liver metastases among patients with positive CEA level, while CA 19-9 level was correlated only with the number of liver metastases (P = 0.0072) among those with positive CA 19-9 level. In the overall series, preoperative CEA and CA 19-9 levels were correlated significantly with survival only at higher cutoff levels. In 46 patients undergoing curative hepatectomy, however, these levels were not correlated with survival, even at higher cutoff levels. In conclusion, the CEA level is closely associated with the extent of liver metastases, while the CA 19-9 level may reflect multiplicity of hepatic deposits. Preoperative measurement of serum CEA and CA 19-9 levels appears to be of some prognostic value.     

Tumour markers CA 19-9 and CA 50 in digestive tract malignancies.

CA 19-9 and CA 50 are tumour marker tests measuring the same carbohydrate structure, sialosyl-fucosyl-lactotetraose--that is, the sialylated Lewis blood group antigen. In addition, the C50 antibody reacts with sialosyl-lactotetraose, which may be expressed in small amounts in some carcinomas. In this study we compared these tests in sera from patients with benign and malignant digestive tract diseases. The sensitivity of the markers for different cancers was also compared at several specificity levels with patients with benign diseases as reference groups. Both markers showed a high sensitivity for pancreatic cancer (77% for CA 19-9; 69% for CA 50) and biliary cancer (88%). The figures in colorectal cancer were almost as high as those reported for CEA; 16-21% elevated values in Dukes A and B tumours and 44-47% in Dukes C and D tumours. The sensitivity for gastric cancer was 48% for both markers. CA 50 had a higher sensitivity for liver cancer (55%) than CA 19-9 (9%), but the proportion of elevated values in benign liver diseases was also higher (33% versus 15%, respectively). Overall, there was good correlation between the CA 19-9 and CA 50 levels, and the difference in sensitivity and specificity was marginal. In clinical practice the greatest value of CA 19-9 and CA 50 is in the diagnosis of pancreatic cancer.     

The Prognostic Value of Preoperative Serum Levels of CEA and CA19–9 in Patients with Gastric Cancer

Objectives : The clinical significance of preoperative serum levels of tumor markers CKA and CA19-9 was evaluated in gastric cancer patients. Methods: Serum levels of CEA and CA19-9 were measured in 663 patients with gastric cancer who underwent laparotomies over a recent 4-yr period (1990-1993). The correlations between the serum levels of tumor markers and several clinic opathological factors were evaluated by univariate analysis. The significance of the tumor markers as prognostic factors was assessed by multivariate analysis. Results : The positivity rates of CEA and CA19-9 were 16.6% and 16.0%, respectively. The positivity of CEA correlated well with the sex of the patients, hepatic, peritoneal, and nodal metastases and the depths of tumors, hut it correlated weakly with a tumor's histological type. The positivity of CA19-9 correlated well with various forms of metastases, depths, and tumor size. A significant difference in prognosis was observed between patients positive and negative for CA19-9 among those undergoing R0 resection. Multivariate analysis also revealed that serum CA19-9 level was better than CEA as a prognostic factor. Conclusions: CA19-9 in the preoperative sera is a good prognostic factor in gastric cancer patients, although tumor markers continue to have only limited diagnostic usefulness.     

Comparison of CA 72-4 with CA 19-9 and carcinoembryonic antigen in the serodiagnostics of gastrointestinal malignancies

Serum levels of the new tumor-associated marker CA 72-4 were measured in healthy controls (n = 64) and patients with benign (n = 410) or malignant (n = 199) gastrointestinal diseases. A cut-off limit of 4 U/ml was established. Tumor-indicating sensitivity was compared with that of the conventional markers carcinoembryonic antigen (CEA) and CA 19-9. In serodiagnostic evaluations CA 72-4 was clearly inferior to CA 19-9 in pancreatic carcinomas (22% versus 82%; all stages) and to CEA in colorectal cancer (32% versus 58%; all stages), with no appreciable diagnostic gain from combined determination. However, in gastric carcinoma CA 72-4 identified 59% of all patients (CA 19-9, 52%; CEA, 25%), and a combination of CA 72-4 and CA 19-9 detected as many as 70%. Positive results correlated roughly with tumor size. Compared with the other two tumor markers, CA 72-4 had a very high specificity (98%) in benign diseases of the gastrointestinal tract, including inflammatory processes, so that elevated serum levels of CA 72-4 should always be taken seriously.     

Prospective evaluation of the diagnostic efficacy of CA 19-9 assay as a marker for gastrointestinal cancers

Levels of a new carbohydrate antigen, CA 19-9, which is a monosialoganglioside identified by a monoclonal antibody raised against colorectal carcinoma cells, were compared to conventional CEA assays in 615 sera from healthy controls, patients with benign gastrointestinal disorders, and patients with cancers of gastrointestinal or extragastrointestinal origin. Whereas CEA levels were higher in smokers, CA 19-9 values were independent of the smoking history. CA 19-9 was undetectable in lymphoma and myeloma patients, but some patients with extraintestinal epithelial cancers expressed this antigen in serum. For benign and malignant gastrointestinal diseases, CA 19-9 displayed higher sensitivity, specificity, and predictive values than CEA. CA 19-9 was elevated as frequently as CEA in patients with metastatic pancreatic cancer, but in patients with localized disease, CA 19-9 was elevated more often than was CEA. In colorectal cancer, patients with and without metastases were detected at similar rates by both assays. It is concluded that CA 19-9 is a marker of epithelial cancers, does not vary with the smoking status, and is superior to CEA in detecting gastrointestinal malignancies, especially those arising from the pancreatic gland.     

CA19-9 as the most significant prognostic indicator of metastatic colorectal cancer

BACKGROUND/AIMS: Colorectal cancer is the third leading cause of cancer-related mortality in Taiwan. We became interested in searching for the factors predictive of survival. Serum CA19-9 (carbohydrate antigen 19-9) level has been reported as a factor predictive of survival in patients with colorectal cancer. A few articles have reported that patients with metastatic colorectal cancer who have normal (< or = 37 U/mL) serum CA19-9 levels survived significantly longer than those with higher serum CA19-9 levels. However, these reports are contradictory and lack definite conclusions. This study was carried out in an effort to evaluate the prognostic significance of serum CA19-9 levels in patients with metastatic colorectal cancer in Taiwan. METHODOLOGY: Between 1991 and 1994, a total of 128 patients with histologically confirmed metastatic colorectal cancers were evaluated retrospectively at Veterans General Hospital-Taipei. All patients had measurable metastatic lesions and life expectancies of more than 3 months. 5-Fluorouracil-based chemotherapy, either in a weekly bolus regimen or a monthly 5-day bolus schedule, were administered to all of them. Data on age, sex, performance status, location of primary tumor, extent of metastases, site of metastases, histological differentiation, serum CEA (carcinoembryonic antigen) and CA19-9 levels were analyzed before chemotherapy to determine their association with survival. Blood samples for CEA and CA19-9 measurement were analyzed using the radioimmunoassay method. Multivariate analysis by the Cox's proportional hazards regression model was performed to determine independent prognostic factors among all of the possible variables. RESULTS: By univariate analysis, serum CA19-9 levels (P < 0.001) and performance status of the patients (P = 0.022) were identified as prognostic factors, while age, sex, location of primary tumor, site of metastasis, histological differentiation, and pre-treatment serum CEA levels were not considered significant. By multivariate analysis, serum CA19-9 levels (P < 0.001) and performance status of the patients (P = 0.014) were still found as independent prognostic factors of these patients. CONCLUSIONS: The data from our study indicate that serum CA19-9 level is the most significant prognostic indicator of patients with metastatic colorectal cancer. It is recommended that stratification for further clinical trials for patients with metastatic colorectal cancer should be carried out according to serum CA19-9 levels.
