Abstract

Aim—To determine whether assays of carcinoembryonic antigen (CEA) and cholesterol in ascites add diagnostic value to cytology.

Methods—The additional diagnostic efficacy of the biochemical assays was studied in the ascitic fluid from 130 patients, of whom 57 had peritoneal carcinomatosis. All diagnoses were verified by subsequent necropsy and/or histology.

Results—CEA concentrations over 5 ng/ml indicated carcinomas, occasionally without peritoneal involvement of the tumour. However, increased values were significantly more common in cancer with peritoneal involvement (p < 0.01), giving a sensitivity of 51% and specificity of 97% for carcinomatosis. A cholesterol value exceeding 1.21 mmol/litre was found in 93% of cancers with peritoneal involvement, but it was not entirely specific (96%) for carcinomatosis. Simultaneous increases in CEA and cholesterol concentrations were specific for carcinomatosis and this combination increased the sensitivity for diagnosing carcinomatosis from 77% with cytology alone to 88%. The correct diagnosis could thus be made in five of 12 cases with inconclusive cytology.

Conclusions—The measurements of both CEA and cholesterol concentrations in ascites give additional specific information about peritoneal carcinomatosis and can therefore be a useful adjunct to cytology—in particular, in inconclusive cases.

Figure 1 Concentrations of carcinoembryonic antigen (CEA) and cholesterol in ascitic fluid. (A) All 130 cases and (B) 35 cases with inconclusive cytology. Benign effusion, open circles; carcinoma without peritoneal involvement, open triangles; peritoneal carcinomatosis, closed triangles. The cut off values for the two analyses are shown as broken lines.

Figure 2 Performance of the carcinoembryonic antigen (CEA) analysis as a measure to detect peritoneal carcinomatosis: (A) receiver operating characteristic plot and (B) diagnostic efficacy as a function of cut off values for the total material and (C) for cases with inconclusive cytology. The last two curves are similar in shape, suggesting an optimal cut off of 5 ng/ml.

Figure 3 Performance of the cholesterol analysis in detection of carcinomatosis: (A) receiver operating characteristic plot and (B) diagnostic efficacy as a function of cut off values for the total material and (C) for cases with inconclusive cytology. The optimal cut off value of 1.21 mmol/litre is the same for the two groups.
