Abstract

Objectives

This study aimed to learn what should be considered in [Guideline of Clinical Trial with Herbal Medicinal Product for Gastric Cancer)] by analyzing the existing guidelines and clinical trials.

Methods

The development committee searched guidelines for herbal medicinal product or gastric cancer developed already. Then, clinical trials for gastric cancer using herbal medicine were searched. The searched trials were analyzed in terms of inclusion and exclusion of participants, intervention, comparator, outcomes and trial design. Then, we compared the results of analysis with the regulations and guidelines of Ministry of Food and Drug Safety to suggest the issue that we will have to consider when making the [Guideline of Clinical Trial with Herbal Medicinal Product for Gastric Cancer].

Results

As a result, few guidelines for anti-tumor agent and clinical trial with herbal medicinal product were searched in the national institution homepage. In addition, 10 articles were searched by using the combination following search term; ‘stomach neoplasm’, ‘herbal medicine’, ‘Medicine, Korean traditional’, ‘Medicine, Chinese Traditional’, ‘TCM’, ‘TKM’, ‘trial’. Most trials included gastric cancer participants with medical history of operation. The type of intervention was various such as decoction, granules, and fluid of intravenous injection. Comparators were diverse such as placebo, conventional treatment including chemotherapy and nutritional supplement. The most frequently used outcome for efficacy was quality of life. Besides, the symptom score, tumor response, and survival rate were used. Safety was investigated by recording adverse events.

Conclusion

We found out some issue by reviewing the existing guidelines and comparing it with clinical trials for gastric cancer and herbal medicinal products. These results will be utilized for developing [Guideline of Clinical Trial with Herbal Medicinal Product for Gastric Cancer].
