The method is innovative and high-tech. In this regard, sufficient experience in its application has been accumulated only in a small number of foreign centers.  These are the IOZK Immuno-Oncological Center (Cologne, Germany), the Children’s Hospital of San Joan de Deu (Barcelona, Spain), the University Hospital (Cologne, Germany).
In most developed countries, cancer immunotherapy is used:
Germany,
Israel
Japan,
USA,
Turkey,
South Korea and so on.
In Ukraine and Russia in recent years, this method of cancer therapy has begun to develop, there are difficulties with drugs. So, for example, only 12 immunotherapy preparations are registered in Ukraine (more than 70 are already used in world practice). In addition, in European clinics, doctors have much more experience in applying this technique.
