title: [Evaluation of CEA, SLX and CA125 in active pulmonary tuberculosis].
abstract: Serum tumor markers (CEA, SLX, CA125) were evaluated in 123 patients with active pulmonary tuberculosis. The results were as follows: Elevated serum CEA, SLX and CA125 levels were found in 16.9%, 39.5% and 44.4%, respectively, of patients with active pulmonary tuberculosis. Markedly elevated serum CA125 levels were found in some cases. On chest X-ray films, the factors associated with elevation of serum tumor marker levels were examined. Serum CEA and SLX levels were correlated with the extent of disease. Pleural effusion had no influence on serum tumor marker levels. Serum SLX levels were higher in patients without a tuberculous cavity than in those with a tuberculous cavity. After therapy with antituberculous drugs, the mean values of serum SLX and CA125 levels significantly decreased. The decrease in mean value of serum CEA levels was not significant, but in 4 of 8 cases, elevated serum CEA levels were normalized after therapy. On the other hand, two cases with increased serum CEA or SLX level died of respiratory failure. These results suggest that to follow up patients with elevated serum tumor markers is useful for the evaluation of disease activity of pulmonary tuberculosis. Further elevation of serum tumor marker levels after antituberculous therapy may indicate the presence of cancer or deterioration of the disease.
