TY - JOUR TI - Optimal therapy policy for cancer growth with stochastic perturbation AU - Wang Yujin AU - Du Yongqiang AU - Zhang Guang AU - Wang Yan AU - Zhang Min JN - Thermal Science PY - 2022 VL - 26 IS - 3 SP - 2743 EP - 2753 PT - Article AB - A stochastic Gompertz model is proposed to study cancer growth with therapy. The model reveals that the therapy and environmental fluctuation can control the tumor size, but its extinction is impossible. Optimal therapy treatment is suggested, and its probability density function is elucidated clearly by the Fokker-Planck equation.
