Immunological studies of patients with asbestosis. I. Studies of cell-mediated immunity.

A variety of cancers have been documented in patients exposed to asbestos dust. Since a deranged immune system may play a rôle in cancer development, the general level of immunocompetence was studied in a group of twenty-six patients with radiographically defined asbestosis, who might be at risk of developing asbestos-related neoplasms. Statistical comparisons were made with a comparable control group. A disproportionate number of the patients displayed cutaneous energy to certain recall antigens and to 2,4-dinitrochlorobenzene. In vitro studies of cellular immunity, as evaluated by phytohaemagglutinin-induced proliferative and cytotoxicity assays, showed significantly lower values amongst the patient group. Serum inhibitors of mitogen-induced lymphocyte transformation were also detected in several of the patients. The possible significance of these findings is discussed.

[The statistics on malignant neoplasms of the urinary and male genital organs in 1987 in the USSR].

The USSR statistics on malignant neoplastic diseases of the urinary system and male sexual organs which comprised 5.7 per cent in the total mortality was presented for the first time. More than a 50 per cent increment in the death rate from these tumors was documented between 1975 and 1987. Annually, prostatic carcinoma is diagnosed in almost 10 thousand patients and cancer of the urinary bladder in 15 thousand patients. Maximal prevalence of the disease has been recorded in the Baltic republics, the Ukraine and Byelorussia. The detection rate of the aforementioned diseases, Stages I-II, is about 40 per cent. The estimate revealed that the total number of the registered oncological patients was 100 thousand persons. The problems in organization of the oncological care system, material and technical supplies and professional training should be considered.
