JKTG-Funded Projects Suggest Cancer Treatment Changes to Combat Drug Resistance

It’s been a productive year since three research teams were awarded grants through the Applied Mathematics in Generating Oncology Solutions (AMIGOS) program. The AMIGOS workshop was hosted by the Jayne Koskinas Ted Giovanis Foundation for Health and Policy (JKTG) and the Breast Cancer Research Foundation (BCRF) and brought researchers from across the country, connecting them with highly-experienced mentors to develop collaborative cancer research projects.


JKTG and BCRF jointly funded three multi-institutional collaborations for projects with potential to substantially advance understanding of cancer biology or improve clinical outcomes. Members from one 2017 AMIGOS multidisciplinary team published five papers during the year. Three of the papers relate directly to the development of resistance to chemotherapy drugs, and generated ideas on how to defer such resistance. The models showed that increased doses defer relapse of the patient, but also increase the level of the drug resistance that is present on relapse, and that pulsed administration of the drugs also results in greater drug resistance upon relapse. These conclusions lead to suggestions for improving treatment to delay or prevent development of drug resistance.


A fourth paper introduces a new software package that provides a tool to identify subpopulations of single cells based on RNAseq data, and the fifth paper models the role of inflammation in causing and protecting against tumor growth. For a full list of manuscripts with hyperlinks as well as the authors see below.
