[Immunologic reactions in cervical cancer]

Under study were immunological indices--the reaction of microprecipitation (tumor and embryonal antigens) and HRDT (tumor and tuberculine antigens) in 305 patients with cancer of the uterine cervix. It was found that most patients showed impaired immune responses: an increased number of persons with specific antibodies circulating in blood serum and increased hypersensitivity of of delayed type. The percentage of positive reactions of microprecipitation and HRDT increases as the tumor spreads. The methods of combined therapy generally improve immunological indices, however, the process starts 1-3 years following the treatment.
