Summary
Chronotherapy leverages circadian rhythms to optimize the timing of cancer treatments—including chemotherapy, radiotherapy, and immunotherapy—maximizing efficacy while minimizing toxicity. Despite over 50 years of evidence showing benefits across diverse solid tumor types, clinical implementation remains limited, suggesting that lighting environments in oncology settings that support robust circadian entrainment could enhance treatment outcomes.
Key Findings
- Chronotherapy for cancer treatment has demonstrated benefits across diverse solid tumor types over more than five decades of research.
- Chrono-chemotherapy, chrono-radiotherapy, hormone therapy, TKIs, antiangiogenic therapy, and immunotherapy all show evidence of circadian-time-dependent efficacy differences.
- Despite favorable evidence, clinical implementation of cancer chronotherapy remains limited, with ongoing research challenges in standardizing timing protocols.
- Circadian disruption (e.g., from poor light-dark cycles) may undermine the synchronization of physiological processes that chronotherapy depends upon.
