‎This given paper can be considered as a continuation of previous work‎, ‎doing on cancer models and their control by a set-valued method‎, ‎in the context of viability theory‎. ‎We analyze a class models of ordinary differential equations‎, ‎taking into account the possibility to directly acting on tumor‎. ‎However we can augment the class by a simple ordinary differential equation of the tumor control term‎, ‎and join it to the other variables state‎. ‎This will allow to exploit results to generalize the approach‎.
