Abstract
Previous studies have related opium and its pyrolysates to the risk of developing certain cancers. The aim of this work was to evaluate the clinical usefulness of determining carcinoembryonic antigen (CEA) and tissue polypeptide antigen (TPA) levels in habitual opium smokers. Serum CEA concentrations were measured in 128 opium smokers and in 44 controls of cigarette only smokers and 47 normal non-smokers by an EIA-based assay. TPA levels were also determined in serum and urine of a subgroup in the study population. The results indicated that serum CEA concentrations are higher in opium smokers than in healthy tobacco smokers (p = 0.004) and non-smokers (p = 0.001). The amount of opium used correlated with the serum CEA level (r = 0.276, p < 0.0001). The mean urine and serum TPA levels of the opium-addicted population were also higher than that of the non-smoking control group, but the differences were not statistically significant. We conclude that opium smoking is associated with elevated serum CEA levels. Therefore, for management of opium users with neoplastic diseases, increased levels of serum CEA should be viewed with caution to avoid misdiagnosis.
