Aim: To estimate the impact of C60 fullerene aqueous solution (C60FAS) on the rate of transplanted malignant tumor growth and metastasis. Methods: Lewis lung carcinoma was transplanted into С57Bl/6J male mice. Conventional methods for the evaluation of antitumor and antimetastatic effects have been used. Results: The C60FAS at low single therapeutic dose of 5 mg/kg inhibited the growth of transplanted malignant tumor (antitumor effect) and metastasis (antimetastatic effect): the maximum therapeutic effect was found to be of 76.5% for the tumor growth inhibition; the increase of animal life span by 22% was found; the metastasis inhibition index was estimated as 48%. Conclusion: It was found that water-soluble pristine С60 fullerenes efficiently inhibit the transplanted malignant tumor growth and metastasis.
