[Whole-body artificial controlled hyperthermia and hyperglycemia in the combined treatment of metastatic kidney cancer].

The attempt of treatment for metastatic renal cancer has not been a success as all the methods known failed to produce any significant effect on the development of metastases. So the search for the means which could potentiate the antitumor activity of the drugs or radiation therapy is still a problem. Various physicochemical methods, including hyperthermia and hyperglycemia, have been used as modifiers of tumor cell responses. When properly employed, hyperthermia and hyperglycemia can produce an antitumor effect. However, their ability to selectively potentiate radiation or chemotherapy is more valuable. A total of 25 patients with renal cell carcinoma and multiple metastases have undergone a comprehensive treatment: radiation therapy for metastases at the total dosage of 60 Gr after removal of the primary tumor. The session of hyperthermia and hyperglycemia was performed in the course of the radiation therapy. During the session chemotherapeutic agents were administered in a half-course dosage. The second part of the radiation therapy was continued after the session. The treatment course included 5 sessions and lasted 12 months. An immediate stabilization of the health status was recorded in all the patients. Some of them had the total or partial regression of metastases. Yet since the follow-up time was not long the authors could make no conclusions.
