Carcinogenesis Associated with Human Papillomavirus Infection. Mechanisms and Potential for Immunotherapy.

Human papillomavirus (HPV) infection is responsible for approximately 5% of all cancers and is associated with 30% of all pathogen-related cancers. Cervical cancer is the third most common cancer in women worldwide; about 70% of cervical cancer cases are caused by the high-risk HPVs (HR HPVs) of genotypes 16 and 18. HPV infection occurs mainly through sexual contact; however, viral transmission via horizontal and vertical pathways is also possible.

[The effect of natural immunomodulators on the lymphocytic natural killer activity in patients with malignant lymphoproliferative diseases].

The conducted investigations showed an apparent immunomodulating action of the studied natural preparations on natural resistance of patients with malignant lymphomas. The modulation effect was the greatest in patients taking esberitox during remission and while receiving radiotherapy. Administration of Ney Tumorin to patients with lymphogranulomatosis during remission appeared to be associated with substantial increase in the content of large granular lymphocytes and level of natural killer activity (almost two--fold) immediately after the end of the treatment and this tendency was to be still seen one--two months later.
