Exploratory Study of Intermittent Hypoxia Intervention on Colorectal Cancer

The hypoxic adaptive response is a form of acquired tolerance that occurs by activating internal cellular protective mechanisms and enhancing immune function.This technology was initially utilized in sports training and high-altitude medicine to enhance strength, endurance, and overall athletic performance, as well as to enhance the body's adaptation to high-altitude hypoxia.

Intermittent hypoxia (IH) refers to periodic hypoxic-normoxic training performed with brief exposure to hypoxia. Previous studies have found that short-term intermittent hypoxia can increase the sensitivity of hypoxia and reduce the severity of acute hypoxia injury, and alleviate acute hypoxia injury by reducing the inflammatory response caused by hypoxia. Intermittent hypoxia has been shown in our team's work to effectively inhibit colorectal cancer tumor progression in mice by enhancing immune cell function. This study aims to explore the safety and efficacy of IH in patients with colorectal cancer using a non-randomized self-controlled trial.
