[Nonspecific resistance during preoperative chemoradiation treatment and UHF hyperthermia of osteogenic sarcoma]. / Nespestsificheskaia rezistentnost' pri predoperatsionnom khimioluchevom lechenii i UVCh-gipertermii osteogennoi sarkomy.

The extent of metastatic spread and the life span depend on the level of nonspecific resistance of the body of patients with osteogenic sarcoma. Chemoradiation therapy reduces antitumoral resistance of patients, and the use of local UHF hyperthermia prevents this negative effect of complex treatment.

[Metastasis of Lewis carcinoma during local UHF hyperthermia]. / Metastazirovanie kartsinomy L'ius pri lokal'noi UVCh-gipertermii.

The paper is concerned with the results of a study of the relation of a metastatic spreading of mouse Lewis carcinoma to temperature distribution in the area of a tumor and healthy tissue damage. It was shown that a significant metastatic spreading inhibition was observed in selective MWF-hyperthermia (43-46 degrees C, 30 min). In the absence of a selective hyperthermal exposure when both tumors and healthy tissues were damaged (at the same thermal dose), there was a tendency to metastatic spreading enhancement. A considerable metastatic growth was noted after tumor-affected limb amputation without hyperthermal exposure.
