In this paper, we are interested in Cauchy problem for a parabolic operator. The main system comes from the modeling of a tumor and describes its evolution over time. From the classical optimal control, we show some results and an optimality system for the considered control problem. It is noteworthy that the classical techniques of the optimal con...

Investigating the mutational history of tumor cells is important for understanding the underlying mechanisms of cancer and its evolution. Now that the evolution of tumor cells is modeled using labeled trees, researchers are motivated to propose different measures for the comparison of mutation trees and other labeled trees. While the Robinson-Fould...

Immune checkpoint blockers (ICBs) have brought great promise to patients with advanced melanoma, a tumor type that was claimed largely incurable not long ago. However, therapeutic resistance to ICBs has limited their utility in the clinic. Here, we provide a commentary on recent research endeavors concerning ICB resistance in melanoma patients.
