Advances in clinical research on pharmacological management of chemotherapy-induced constipation in gastrointestinal tumor: A perspective.

Gastrointestinal tumors, including those of the stomach, colon, rectum, and esophagus, present significant global health challenges. Chemotherapy, essential for treating these cancers, often causes constipation, adversely affecting patients' quality of life. This study examines the mechanisms behind chemotherapy-induced constipation, such as the direct impact of chemotherapeutic drugs on intestinal function, reduced fluid intake, decreased physical activity, opioid use, and psychological stress. While traditional treatments like stimulant and osmotic laxatives are commonly used, emerging therapies such as 5-HT4 receptor agonists and probiotics show promise. Traditional Chinese medicine offers additional strategies with herbal remedies and dietary adjustments. Future research should prioritize precision medicine, combining pharmacological and non-pharmacological approaches, and developing innovative therapeutics utilizing biologics and nanotechnology. Ongoing research is crucial for improving chemotherapy-induced constipation management, aiming to enhance treatment outcomes and the quality of life for chemotherapy patients with gastrointestinal tumors.
