About this Research Topic
This timely research topic is focused within a field that produced two Nobel prize awards in Physiology or Medicine, in 2017 for circadian rhythm research, and in 2018 for the discovery of cancer immunotherapy. The aim of this special issue is to highlight clinical, translational and epidemiological science - that includes objective assessments of both circadian disruption and cancer hallmarks - in order to help elucidate the impact of circadian rhythms on processes associated with cancer and its treatments, immunotherapy in particular.
We welcome submission of Reviews, Original Research and Methodological Articles, with a special interest in the following research topics:
- Science focused on the newly proposed hallmark parameters of “unlocking phenotypic plasticity,” “nonmutational epigenetic reprogramming,” “polymorphic microbiomes,” and “senescent cells”
- Experimental, translational or clinical evidence on the impact of circadian rhythms on the efficacy and safety of immune-based anticancer therapeutics (immune checkpoint inhibitors, chimeric antigen receptor T-cell therapy, cytokines)
- Advancements in clinical measurements of circadian rhythms (eg, wearable biosensors and e-health technology) to derive non-invasive measures, in addition to establishing clinical cutoff scores, with the aim of more easily integrating circadian measurements into clinical practice, especially in patients on immunotherapy
- Clinical strategies that advance precision in targeting chrono- and behaviorally-modulated treatments (eg, pharmacologic timing, exercise, bright light exposure, chrono-nutrition) in cancer survivors
- Studies that aim to evaluate the impact of circadian rhythms on response to immune-based cancer treatment in humans.
- Data on the circadian rhythm changes in cancer cells and normal cells under different treatments, particularly immunotherapy.
- Evidence on the circadian modulation of the interaction between cancer cells and tumor microenvironment, in particular immune cells
- Data on circadian rhythms and cancer stem cells
- Clinical data on the impact of circadian rhythm disruption on cancer recurrence and progression after treatment, and/or side-effects of immunotherapy and other cancer treatments.
- Gaining a better understanding of how sleep and circadian rhythm disruption each differentially influence host-tumor defenses to delineate which of these two processes may be the stronger driver of cancer cell growth and progression, as well as cancer treatment response, particularly to immunotherapy.
