Modern Cryosurgery against Cancer in the 21st Century

Looking at the development of the disease statistics of the past decades the enhancing rate of cancer disease and cancer deaths attracts attention, despite the exorbitantly increased financial expenditure for diagnosis and therapy (Big appliances, intensive medicine, etc.). In the last years no significant improvements could be achieved in this area, whereby the applied therapeutical methods are of limited efficiency. Among the other cancer kinds particularly breast cancer is advancing. Secondary manifestations like metastases and local recurrences due to protracting cancer cells as a result of diagnostic interventions mean a death sentence for patients with mamma carcinoma.

A new way of thinking must, thus, prevail in the future of cancer research and treatment. New disguise and treatment methods should enhance the healing rate of the cancer disease. Modern cryosurgery - a particularly gentle operation technique - experiences nowadays an international attention and dissemination. Good results can be proven through long-standing practical experience and numerous international publications. Thereby it has been shown that a successful employment of this method can only be reached through the development of effective medical-technical appliances. The existing new concept of a multimodal oncology demonstrates how modern, cryosurgical technology for diagnosis, prevention and treatment of cancer could be developed and produced. What is Cryosurgery?

Cryo-, freeze- or cold-surgery is the operative cutting of tissue or the targeted

Destruction of pathological tissue by induced cold necroses at temperatures down to -196C. Tumors are usually not excised but shock-frozen. In these cases vacuum-isolated cryoinstruments (cryoprobes, cryoscalpels, cryoclamps, cryoneedles) are used. These instruments are cooled to -170C to -190C by the evaporation of liquid nitrogen.

The prerequisites for the art of cryosurgery include not only long experience in the use of the instruments but also experimental and clinical knowledge. In the last 22 years, Professor Dr. Nikolai N. Korpan and his colleages together in co-operation with other international scientific institutios have developed and refined new cryosurgical techniques for operative procedures in patients with liver and pacreas tumors, breast cancer, lymph node metastases, and recurrent skin cancer.

Cryosurgery is established in medical practice both as a single technique as well as supplementary to other oncological treatments. The development of the cryocautery (on the Cooper principle), which makes the destruction of large areas of tissue by extreme hypothermia possible, was the technical prerequisite for a cryosurgical method applicable in general surgery. However, the reliable destruction of tumors requires the use of high-performance devices.
