Polyamine levels in gynecologic malignancies

Polyamines are closely related to many aspects of cell growth. Since increased amounts of polyamines in the urine of human cancer patients were reported in 1971, polyamines have been studied from the standpoint of tumor markers. In this study, polyamines in erythrocytes, plasma and urine were determined in 42 controls and 105 patients with gynecologic malignant tumors. The changes in polyamine levels were investigated before and after treatment. With advances in the stage of uterine cervical cancer, the frequency of abnormal levels of polyamines (concentrations greater than two standard deviations above the mean control level) became greater, and reached nearly 80% in recurrent and ovarian cancer. In the early stage of cancer, the diagnostic value was low. Comparison with carcinoembryonic antigen (CEA) was also performed. The polyamines lack specificity for malignant diseases, but they can be used to some extent as a tumor marker in the gynecologic field.
