The plans of introduction of cryosurgery in the east

Vira FAZLEYEVA

During the last week, Vietnamese specialists in military medicine and technology were acquainted with the clinical aspects of cryosurgery in the leading Kyiv Institutes and Hospitals. Their visit to the capital was continuation of the fruitful cooperation initiated by representatives of both parties at the end of the last year. Then the Ukrainian producers of cryosurgical equipment of “Pulse” SPC visited Vietnam on an intergovernmental delegation on the Days of Ukrainian Science and Technology in Vietnam, where the achievements of the Ukrainian science and advanced technologies were displayed.

Then the Managing Director of the Advanced Technologies Center of the Vietnamese Academy of Sciences, Doctor Le Hu Ziyen and Head of General Surgery Department of Central Military Hospital in Hanoi, Colonel of medical service Chieu Cheu Ziong expressed their wish to be acquainted with the clinical aspects of cryosurgery in various spheres of surgery in the country-producer of “Cryo-Pulse” cryosurgical plant.

The Vietnamese guests “made” their Kyiv colleagues answer their numerous questions, display the advantages of the modern method, and explain in detail, an in general, pass certification of “maturity” of the local technology.

The program of visit of the Vietnamese colleagues was heavy and diversified. The foreign specialists visited the Central Military Clinical Hospital of the Ministry of Defence of Ukraine, Hospital of the Internal Ministry of Ukraine, the Kyiv Regional Clinical Hospital, the Kyiv City Oncological Hospital, Institute of Oncology of AMS of Ukraine, Medical Institute of Ukrainian Association of Folk Medicine, as well as several basic Chairs of O.O. Bogomolets National Medical University and of P.L. Shupik National Medical Academy of Postgraduate Education.

The Vietnamese specialist took a keen interest in clinical application of cryosurgery and cryotherapy in the cases of oncological diseases of hepatopancreatobiliar zone, in urology, obstetrics and gynecology, malignant tumors of head and neck, proctology, dermatology, and in case of mammary gland cancer. The radical and palliative methods of intervention, applied at present in cryosurgery, differ in operation technique. The following techniques may be applied: cryoablation (complete radical cryodestruction of a tumor or organ), cryoresection (cryodestruction with further resection of the frozen part of organ), cryoextirpation (fixation of the pathological area to cryoapplicator by way of freezing), and adjuvant cryodestruction (as an additional method after the basic stage of operation with the use of the traditional method). The foreigners highly appreciated the advantages of the cryosurgical method over a traditional operation, as in case of a cryosurgical operation, alongside with usual radical cryosurgical destruction; the inoperable tumors are subject to destruction as well. The Vietnamese specialists visited twice the operation room of the Head of General Surgery Chair No. 1 of O.O. Bogomolets NMU, Research Supervisor of the Kyiv Center for Surgery of Liver, Biliary Ducts, and Pancreas, Doctor of Medicine Oleksiy Dronov, where they witnessed resection of a thirty-kilogram tumor from abdomen. To save life of the patient became possible greatly owing to excision of a malignant tumor with further application of cryotechnology.

The foreigners made sure of great prospects of cryotechnology after their meeting with the oncology surgeon of the Oncology Chair of P.L. Shupik National Medical Academy of Postgraduate Education (NMAPE), Doctor of Medicine professor Rakhman Taschiyev who operates malignant tumors of abdominal zone and mammary gland cancer that is widely spread now, with the application of cryodestruction method. He thoroughly studies the processes occurring in the pathological organ and of a patient following cryosurgical intervention and records them, as the new method consists of two stages — freezing and natural thawing of tissue without heating, and understanding the capabilities of such processes may influence the final results of cryosurgical interventions. In particular, the professor noticed that at the stage of thawing, antitumor antigens are formed in the pathological organ and with blood circulation are spread over the whole body. Thus, owing to cryo-influence, a body is able to elaborate its own vaccine against malignant neoplasms that prolongs the life of certain patients with oncopathology of hepatopancreatobiliar zone for 10-12 years. In availability of multiple metastatic affection, when cryoapplicator renders harmless the largest tumor of the pathological nidus with diameter of up to 3 mm, all small oncological tumors would resolve owing to cryodestruction, which has a strong immunogenic influence. Taking account of the fact that a steady growth of the incidence rate of mammary gland tumor (MGT) is observed during the last years, holding the first place among oncological diseases and the third place as to mortality rate, the application of cryosurgical methods of treatment in combination with complex MGT treatment (radical mastectomy, radiotherapy, chemotherapy, and hormonotherapy) gives positive results. The last two years’ observation of patients that were subject to cryosurgical treatment with self-vaccination, evidences the absence of recrudescences and metastases, prolongation of life of the women and improvement of its quality, whereas the application of the traditional methods alone for MGC treatment proves occurrence of cancer recrudescence in 15-20% of the operated women. Therefore, owing to cryosurgery, the operative interventions became organ-sparing, practically bloodless, have promising late results and are low-traumatic.

Not without reason they say that it is better to see once than to hear several times. The Vietnamese specialists were fully satisfied with everything seen and heard by them. It is not only impression that they will bring to their country, but also a contract for purchase of the modern cryogenic equipment for the medical establishments of Vietnam, the experience of application of cryosurgical methods of treatment in various spheres of medicine, which at present are illimitable.
