Methods of monitoring and evaluating the status of a tumor undergoing treatment includes monitoring in vivo at least one physiological parameter associated with a tumor in a subject undergoing treatment, transmitting data from an in situ located sensor to a receiver external of the subject, analyzing the transmitted data, repeating the monitoring and transmitting steps at sequential points in time and evaluating a treatment strategy. The method provides dynamic tracking of the monitored parameters over time. The method can also include identifying in a substantially real time manner when conditions are favorable for treatment and when conditions are unfavorable for treatment and can verify or quantify how much of a known drug dose or radiation dose was actually received at the tumor. The method can include remote transmission from a non- clinical site to allow oversight of the tumor's condition even during non-active treatment periods (in between active treatments). The disclosure also includes monitoring systems with in situ in vivo biocompatible sensors and telemetry based operations and related computer program products.

L'invention concerne des procédés relatifs au phasage et à l'évaluation de l'état d'une tumeur en traitement, qui consistent à surveiller in vivo au moins un paramètre physiologique associé à une tumeur chez un sujet en traitement, puis à transmettre les données depuis un capteur in situ vers un récepteur extérieur au sujet, à analyser les données, à reproduire les étapes de surveillance et de transmission en des points séquentiels dans le temps et à déterminer une stratégie de traitement. On assure ainsi un suivi dynamique dans le temps des paramètres contrôlés. Les procédés considérés permettent aussi d'identifier sensiblement en temps réel les conditions favorables et défavorables à un traitement, et de vérifier ou de quantifier la dose de médicament ou de rayonnement connue effectivement appliquée à la tumeur. Les procédés en question peuvent consister à effectuer une télétransmission depuis un site non clinique, pour suivre la tumeur même pendant les périodes non actives du traitement (entre phases actives). L'invention concerne également des systèmes de suivi reposant sur l'utilisation de capteurs biocompatibles in situ in vivo, des opérations à base de télémétrie et des programmes informatiques connexes.
