Complementary and Alternative Medicine in Oncology: A Concise Review of Utilization, Evidence, and Integration Challenges

Key Takeaways for GI Nurses

• Many oncology patients receiving care in GI/endoscopy units are likely using complementary and alternative medicine (CAM) therapies alongside conventional treatment, often without disclosing this to their healthcare providers
• Understanding CAM utilization patterns and evidence base is crucial for providing comprehensive patient assessment and avoiding potential interactions with endoscopic procedures or medications
• Integration challenges between conventional care and CAM approaches require structured communication protocols to ensure patient safety during endoscopic interventions
• Professional development in CAM awareness can enhance therapeutic relationships and improve patient-centered care in gastroenterology settings

Clinical Relevance

For GI and endoscopy nurses, this research highlights a critical gap in routine patient assessment protocols. Cancer patients undergoing diagnostic or therapeutic endoscopic procedures frequently utilize herbal supplements, nutritional therapies, or other CAM modalities that may impact procedural safety, sedation effectiveness, or post-procedure recovery. The integration challenges identified in this review suggest that many patients may not voluntarily disclose CAM use during pre-procedure assessments, creating potential risks for drug interactions, bleeding complications, or altered physiological responses during endoscopy.

The evidence review component of this research provides valuable guidance for developing evidence-based patient education materials and counseling approaches. GI nurses are uniquely positioned to bridge the communication gap between patients' holistic health practices and medical interventions. By understanding both the utilization patterns and scientific evidence surrounding common CAM therapies, nurses can engage in informed discussions about timing of herbal discontinuation before procedures, potential interactions with conscious sedation, and safe integration of complementary approaches during the peri-procedural period.

From an operational standpoint, this research supports the need for enhanced pre-procedure screening protocols that specifically address CAM use. Unit policies may need revision to include standardized questions about supplements, herbal remedies, and alternative therapies. Additionally, staff education programs focusing on common CAM modalities used by oncology patients can improve the quality of patient interactions and ensure comprehensive care planning that respects patients' holistic health approaches while maintaining procedural safety standards.

Bottom Line

GI and endoscopy nurses must proactively assess and address complementary and alternative medicine use among cancer patients to ensure procedural safety and provide patient-centered care. Developing structured protocols for CAM screening, understanding evidence-based interactions, and fostering open communication about holistic health practices will enhance both patient safety and therapeutic relationships in gastroenterology settings where oncology patients frequently receive care.
