The paper discusses results of treatment of advanced (over 100 cm in size) cervical carcinoma. Fifty-eight females of the control group received complex split-course radiotherapy whereas in 38 patients of the study group radiation was supplemented with thymalin immunotherapy at the first and second stages. The results showed the latter therapeutic modality to offer clear advantage over radiotherapy alone, viz. it allowed wider application of radical surgery and assured better results of treatment of patients previously considered incurable.
