Intravesical PstS1 treatment after sensitization with PBS, PLG-particles or PLG-particles/BSA. Ten days before inoculation of MB-49 tumor cells mice were s.c. sensitized by injection of PBS (A), L-particles (B) or L-particles loaded with BSA (C). On days 1, 8, 15 and 22 after tumor challenge, mice were treated by intravesical instillation of PstS1 (A/B/C). Mice which received s.c. PBS and intravesical PBS served as control. Survival of mice was analyzed by Kaplan-Meier curve and log rank test.
