Prospects of using Antagonist Histamine H2-Receptor (Cimetidinum) as   Adjuvant for Melanoma Biotherapy Treatment
  Improvement of anti-tumor biotherapy effectiveness by modification of immune response with histamine H2 receptor Cimetidinum (CM) was studied using the experimental murine model of B16 F10 melanoma in vivo. It is shown that skin melanoma biotherapy by antitumor whole-cell GM-CSF-producing vaccine with the addition of CM (in dose of 25 mg/kg, daily for 5 days) increases preventive effects of vaccination. 33 % of mice did not have tumor growth within 60 days of observation. Average life span of animals exceeded those of the control group up to 68 %. Using CM-combined bio-chemotherapy doesn't improve therapeutic effect, however in the case of a monotherapeutic approach tendency for increased average life-time and decreased metastatic processes in mice with the developed tumors was noticed. Aquired data provides expediency to study the further application of CM as adjuvant for skin melanoma vaccinotherapy, and also the necessity to verify the immune status of an organism against the complex bio-chemotherapy.
