Mathematical model of cancer growth controled by metronomic chemotherapies

چکیده
We propose in this article to compare the efficiency of two chemotherapeutic schedules: the traditional and the metronomic. For this, we develop a new mathematical model describing the growth dynamics of tumor and endothelial cells as well as the impact of molecules as oxygen or vascular endothelial growth factor on this dynamics. The model construction: biological assumptions, description of the equations and their discretization, constitutes the core of the article. Numerical experiments illustrate the expected behavior of the disease under the two chemotherapeutic schedules. Résumé. Nous proposons dans cet article de comparer l’action de deux protocoles d’administration de chimiothérapie. Pour cela, nous développons un nouveau modèle mathématique décrivant la dynamique de croissance de diverses cellules tumorales et endothéliales et l’impact sur cette dynamique de molécules comme l’oxygène et de facteurs de croissances endothéliales. La construction du modèle, à savoir les hypothèses biologiques sous-jacentes, la description des équations et leur discrétisation constitue le coeur de cet article. Nous donnons quelques illustrations numériques de l’évolution de la maladie sous l’action des deux protocoles thérapeutiques et retrouvons les résultats attendus par les oncologues.

متن کاملMetronomic chemotherapy enhances the efficacy of antivascular therapy in ovarian cancer.
Metronomic chemotherapy is the frequent administration of low doses of chemotherapeutic agents targeting tumor-associated endothelial cells. We examined the efficacy of metronomic taxanes alone and in combination with AEE788-a dual epidermal growth factor receptor (EGFR) and vascular endothelial growth factor receptor (VEGFR) inhibitor-in an orthotopic mouse model of ovarian cancer. Growth-modu...
متن کاملBridging the gap between cytotoxic and biologic therapy with metronomic topotecan and pazopanib in ovarian cancer.
This study aimed to investigate the antitumor and antiangiogenic effects utilizing a novel therapy regimen of metronomic topotecan and pazopanib, a multireceptor tyrosine kinase inhibitor. In vitro (Western blot) and in vivo dose-finding experiments were done following pazopanib therapy in ovarian cancer models. Pazopanib and metronomic (daily) oral topotecan therapy was examined in an orthotop...

PURPOSE The development of effective therapeutic approaches for treatment of metastatic melanoma remains an immense challenge. Present therapies offer minimal benefit. Although dacarbazine chemotherapy remains the standard therapy, it mediates only low response rates, usually of short duration, even when combined with other chemotherapeutic agents. Thus, new therapeutic strategies are urgently ...
متن کاملPotent preclinical impact of metronomic low-dose oral topotecan combined with the antiangiogenic drug pazopanib for the treatment of ovarian cancer.
Low-dose metronomic chemotherapy has shown promising activity in many preclinical and some phase II clinical studies involving various tumor types. To evaluate further the potential therapeutic impact of metronomic chemotherapy for ovarian cancer, we developed a preclinical model of advanced human ovarian cancer and tested various low-dose metronomic chemotherapy regimens alone or in concurrent...
