Unconventional Treatments for Pancreatic Cancer: A Systematic Review

This study aims to review the existing literature on the efficacy and safety of unconventional treatments among pancreatic cancer patients, including the use of natural products, dietary supplements, probiotics, whole medical systems, and body-based therapies.

An electronic, systematic, and comprehensive literature review was conducted searching for studies up to November 2024 following the PRISMA 2020 guidelines. Randomized controlled trials and prospective and retrospective studies assessing the efficacy and safety of unconventional treatments for pancreatic cancer were considered eligible. Data on overall survival, quality of life, and treatment tolerability were extracted.

A total of 21 studies, providing data from 3095 patients, met the inclusion criteria. Various types of unconventional treatments are used in pancreatic cancer patients, including Chinese herbal medicine (CHM), mistletoe extract (ME), curcumin, and electroacupuncture. Among these, the use of CHM and curcumin concomitant with standard therapy was associated with survival and quality-of-life benefits. Electroacupuncture reduced pancreatic cancer pain intensity in a cost-effective manner. The data on ME are mixed and of insufficient quality for drawing definitive conclusions.

Some unconventional treatments showed potential benefits in improving overall survival and quality of life in pancreatic cancer patients within an integrative oncology setting. Further high-quality studies are needed to provide robust, rigorous, and ethical evidence to support their integration into future guidelines, ensuring a holistic approach to cancer treatment.
