This study identified 222 eligible trials from 19 countries, encompassing 17 specific cancer types and 32 symptoms. The most common cancer types included breast cancer, head and neck cancer, colorectal cancer, lung cancer, and gastric cancer, accounting for almost half of all registered trials (48.2%). The top five symptoms included chemotherapy-induced peripheral neuropathy (CIPN), cancer-related pain, cancer-related fatigue, chemotherapy-induced nausea and vomiting (CINV), and gastrointestinal dysfunction.
Purpose This study sought to explore and summarize the global state of acupuncture clinical trials enrolling cancer patients included in international registries to date. Methods All relevant trials evaluating acupuncture-related interventions for the treatment of cancer that were registered in 16 trial registries from January 1, 2001, through December 31, 2020, were identified. Subsequent publications related to these trials were additionally retrieved from the PubMed, Cochrane Library, Embase, CNKI (China National Knowledge Infrastructure), VIP (China Science and Technology Journal Database), and Wanfang databases. We compared information included in these registries regarding completed trials with any associated publications, with a focus on study design, sample size, and selective reporting, based on the registered protocol. Results In total, 222 eligible trials across 19 countries were identified. These trials included 17 specific cancer types and 32 symptoms. The five most common cancer types were breast cancer, head and neck cancer, colorectal cancer, lung cancer, and gastric cancer, accounting for almost half of all registered trials (48.2%). The top five symptoms included in these trials were chemotherapy-induced peripheral neuropathy (CIPN), cancer-related pain, cancer-related fatigue, chemotherapy-induced nausea and vomiting (CINV), and gastrointestinal dysfunction. The overall rate of article publication was low, with publications being associated with just 33.3% of these registered trials. Conclusions This review is the first snapshot of the landscape of acupuncture clinical trials registered in international trial registries, providing a methodological basis for the management of common treatment- and disease-related side effects among cancer patients undergoing acupuncture and offering useful information that will guide future acupuncture-focused research.
