| Summary: | <i>Background and Objectives</i>: Nausea and vomiting (NV) are common and distressing adverse effects among cancer patients undergoing treatment. Despite the widespread use of pharmacological antiemetics, these medications are often insufficient for controlling nausea and may cause medication interactions and side effects. Acupuncture has been proposed as a complementary therapy; however, the comprehensive analysis of its effects on NV across all emetogenic cancer treatments remains limited. This systematic review and meta-analysis aimed to evaluate the effectiveness and safety of acupuncture in managing NV in cancer patients undergoing chemotherapy, radiotherapy, or surgery. <i>Materials and Methods</i>: We conducted a comprehensive search across three electronic databases and two clinical registry platforms from inception to December 2024. Randomized controlled trials (RCTs) evaluating acupuncture for NV in cancer patients were included. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a random-effects model. Safety outcomes were assessed based on the Common Terminology Criteria for Adverse Events (CTCAE). <i>Results</i>: Seventeen RCTs met the inclusion criteria, with twelve studies included in the meta-analysis. Acupuncture did not demonstrate significant effects on acute nausea (RR: 0.98; 95% CI: 0.84–1.15; <i>p</i> = 0.80) or acute vomiting (RR: 0.93; 95% CI: 0.65–1.32; <i>p</i> = 0.67). However, it significantly reduced delayed vomiting (RR: 0.76; 95% CI: 0.61–0.95; <i>p</i> = 0.02). Subgroup analysis demonstrated significant effects when acupuncture was administered for at least five days (RR: 0.56; 95% CI: 0.39–0.81; <i>p</i> = 0.002). The most frequently used acupoints were PC6, ST36, CV12, LI4, LR3, and ST25. No serious adverse events related to acupuncture treatments were reported, with only minor AEs such as localized bleeding and mild bruising observed. <i>Conclusions</i>: Acupuncture represents a safe and effective complementary therapy for managing delayed vomiting in cancer patients receiving emetogenic treatments. Clinicians can anticipate optimal benefits from at least five days of treatment, particularly using acupoints PC6, ST36, CV12, LI4, LR3, and ST25. Further high-quality studies are needed to establish standardized treatment regimens and explore its comprehensive effects on NV. |
