A nonlinear model predictive control (NMPC) algorithm was developed to dose the chemotherapeutic agent tamoxifen based on a novel saturating-rate, cell-cycle model (SCM). Using daily tumor measurements, the algorithm decreased tumor volume along a specified reference trajectory in simulated animals over 4 months. In mismatch case studies, controllers based on the Gompertz model (GM) yielded equivalent total drug delivered and elapsed time to t(99%) reference step convergence to those obtained using the SCM, though this performance was dependent on the cell-cycle phase of drug effect. Overall, the NMPC algorithm is suitable for dosing chemotherapeutics with regular administration schedules and may be adapted for regularly administered chemotherapeutics other than tamoxifen.
开发了一种非线性模型预测控制(NMPC)算法,用于基于一种新型的饱和速率细胞周期模型(SCM)对化疗药物他莫昔芬进行给药。利用每日肿瘤测量数据,该算法在4个月的模拟动物实验中,使肿瘤体积沿着指定的参考轨迹减小。在失配案例研究中,基于Gompertz模型(GM)的控制器在达到t(99%)参考步收敛时,所输送的总药物量和经过时间与使用SCM时相当,不过这种性能取决于药物作用的细胞周期阶段。总体而言,NMPC算法适用于按常规给药方案进行化疗药物给药,并且可能适用于除他莫昔芬之外的其他常规给药的化疗药物。
