[The effect of a Rhodiola rosea extract on the incidence of recurrences of a superficial bladder cancer (experimental clinical research)].

Oral administration of Rhodiola rosea extract to a small group of patents (n = 12) with superficial bladder carcinoma (T1G1-2) improved the characteristics of the urothelial tissue integration, parameters of leukocyte integrins and T-cell immunity. The average frequency of relapses for these patients has been found to fall twice, though statistical differences were not significant.
