title: [Antitumor effects of electrothermal and electrochemical therapy on mice with sarcoma180].
abstract: OBJECTIVE
  To explore the anti-tumor effects and the mechanism of a new treatment for Sarcoma180 in mice using both hyperthermia (H) and electrochemical therapy (ECT).
  
  
  METHODS
  A group of mice with Sarcoma180 (1 cm in diameter) were divided randomly into four groups and given different treatments: Control, ECT alone, H alone and electrothermal & electrochemical therapy (ETECT). The volumes of the tumors were calculated everyday after treatment. The tumor tissues were examined morphologically at 0, 6, 24 and 72 hours after treatment.
  
  
  RESULTS
  The tumors treated with ETECT were completely destroyed, and did not recur within a period of ten days by pathological examination. Results of this group were significantly different with the other groups (P<0.01). However, recurred tumors were found in 6 mice of H group and 5 mice of ECT group, respectively.
  
  
  CONCLUSIONS
  Based on the results obtained, ETECT induced by ETECD (D-device) is an effective way to eliminate cancer. It is capable of completely destroying cancer cells in a short time. The rate of Sarcoma180 inhibition is 100%, and malignant cells can't recur. The research provided theoretical and experimental bases for the treatment of oral cancer by a new approach to treat oral cancer.
