Area of Science:

  • Cellular physiology
  • Chronobiology
  • Oncology

Background:

  • Circadian rhythms, governed by a 24-hour cellular clock, regulate physiological processes.
  • The suprachiasmatic nucleus coordinates the internal clock, influencing environmental adaptation.
  • Circadian organization impacts the body's response to anticancer agents and tumor growth.

Purpose of the Study:

  • To explore the clinical relevance of chronotherapy in cancer treatment.
  • To evaluate chronotherapeutic schedules for metastatic colorectal cancer management.

Main Methods:

  • Review of randomized, multicenter trials on chronotherapy.
  • Application of chronotherapeutic schedules using oxaliplatin for colorectal cancer.

Main Results:

  • Demonstrated clinical relevance of chronotherapy in randomized trials.
  • Documented safety and activity of oxaliplatin via chronotherapeutic schedules.
  • Achieved unprecedented long-term survival in metastatic colorectal cancer patients.

Conclusions:

  • Chronotherapy represents a novel approach to medicosurgical management of colorectal cancer.
  • Chronotherapy holds promise for enhancing current cancer treatments.
  • Chronotherapy can optimize the development of novel anticancer and supportive agents.
