Abstract:
Next-generation sequencing technologies have provided us with a precise description of the mutational burden of cancers, making it possible to identify targetable oncogene addictions. However, the emergence of resistant clones is an inevitable limitation of therapies targeting these addictions. Alternative approaches to cancer treatment are therefore required. We propose here a novel approach, based on the notion of conflicting signals and on a phenotypic description of cancer cells. "Phenotype" is an inherently complex notion that we describe in the conceptual framework of the epigenetic landscape, with a view to bridging the gap between theory and practice at the patient's bedside. By passing from theory to the description of several examples, we will illustrate how this approach can facilitate data analysis and the design of new strategies for cancer treatment.

Insights
Targeting cancer oncogenes faces resistance. This study proposes a novel approach using conflicting signals and cancer cell phenotypes within an epigenetic landscape framework for new treatment strategies.
Area of Science:
- Oncology
- Genomics
- Epigenetics
Background:
- Next-generation sequencing identifies targetable oncogene addictions in cancer.
- Therapies targeting oncogene addictions are limited by the emergence of resistant clones.
- Alternative cancer treatment strategies are needed.
Purpose of the Study:
- To propose a novel cancer treatment approach based on conflicting signals and cancer cell phenotypes.
- To describe cancer cell phenotype within the conceptual framework of the epigenetic landscape.
- To bridge the gap between theoretical concepts and practical bedside applications.
Main Methods:
- Utilizing the concept of conflicting signals in cancer therapy.
- Employing a phenotypic description of cancer cells.
- Framing the approach within the epigenetic landscape model.
Main Results:
- The proposed approach facilitates data analysis for cancer treatment.
- This framework aids in designing new cancer treatment strategies.
- Illustrative examples demonstrate the approach's utility.
Conclusions:
- A novel approach integrating conflicting signals and phenotypic descriptions offers a promising avenue for cancer treatment.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
