Mode Of Transport

We present a mathematical model for the concentrations of proangiogenic and antiangiogenic growth factors, and their resulting balance/imbalance, in host and tumor tissue. In addition to production, diffusion, and degradation of these angiogenic growth factors (AGFs), we include interstitial convection to study the locally destabilizing effects of interstitial fluid pressure (IFP) on the activity of these factors. The molecular sizes of representative AGFs and the outward flow of interstitial fluid in tumors suggest that convection is a significant mode of transport for these molecules. The results of our modeling approach suggest that changes in the physiological parameters that determine interstitial fluid pressure have as profound an impact on tumor angiogenesis as those parameters controlling production, diffusion, and degradation of AGFs. This model has predictive potential for determining the angiogenic behavior of solid tumors and the effects of cytotoxic and antiangiogenic therapies on tumor angiogenesis.

Zusammenfassung. Das Prostatakarzinom zeigt eine hohe Prävalenz und ist daher für die behandelnden Ärzte medizinisch, aber auch gesundheitspolitisch relevant. PSA-Screening senkt die karzinomspezifische Mortalität, ist jedoch aufgrund der hohen Prävalenz mit einer Überdiagnostik verbunden. Dies fordert im Gegenzug einen verantwortungsbewussten Umgang mit dem PSA-Test («smarter screening»). Durch die robotergestützte Prostatektomie steht eine Therapie mit geringer Morbidität zur Behandlung des lokalisierten Prostatakarzinoms zur Verfügung. Das fokale Behandlungskonzept der HIFU (high-intensity focused ultrasound) ist vielversprechend, jedoch noch klinisch experimentell und sollte im Rahmen von Studien angeboten werden. Die Behandlungsmöglichkeiten beim metastasierten Prostatakarzinom wurden entscheidend vervielfältigt. Chemotherapie und die sekundäre Hormontherapie werden voraussichtlich vermehrt in früheren Phasen der Krankheit eine Rolle spielen, wodurch die Therapie für den einzelnen Patienten immer komplexer wird und individuell angepasst werden muss.
