Study summary

This study aims to elucidate the therapeutic efficacy of electroacupuncture in managing chemotherapy-induced gastrointestinal symptom clusters through clinical research. Building upon this foundation, multi-omics analyses will be conducted to investigate the regulatory effects and underlying mechanisms of electroacupuncture on gastrointestinal symptoms. Ultimately, genomic studies will be performed to further clarify the key targets of electroacupuncture intervention, thereby providing high-level evidence-based medical support and theoretical foundations for optimizing electroacupuncture strategies in addressing chemotherapy-induced gastrointestinal symptoms in patients with cancer.

Read the detailed description

This prospective, multicenter, randomized, double-blind, sham-controlled trial investigates the efficacy of electroacupuncture (EA) combined with standard quadruple antiemetic therapy (olanzapine + dexamethasone + 5-HT3 receptor antagonist + NK-1 receptor antagonist) versus sham EA plus identical antiemetic regimen for chemotherapy-induced gastrointestinal symptom clusters (nausea, vomiting, poor appetite, and xerostomia ). The EA group receives true acupuncture with continuous wave stimulation (2Hz frequency, ≤10mA intensity as tolerated, 30min/session) administered: (1) 1-2h pre-chemotherapy on Day 1, and (2) daily at 9:00-10:00 from Days 2-4. Controls receive sham EA with an identical treatment schedule and the same antiemetics. Assessments during Days 1-5 include: Researchers record the incidence of nausea, vomiting, poor appetite, and xerostomia; Collection of weight, ECOG scores, and EQ-5D-5L questionnaires; documentation of antiemetic/chemotherapy use, concomitant medications, and adverse events; laboratory tests per cycle; and imaging when indicated. Blood samples are preserved every two cycles. Primary/secondary outcomes and adverse events are systematically evaluated.

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Experimental
    true acupuncture + standard quadruple antiemetic therapy

    The experimental group received electroacupuncture (EA) combined with a standard quadruple antiemetic regimen comprising Olanzapine (2.5 mg orally daily, days 1-4), dexamethasone (10 mg intravenously day 1; 7.5 mg intravenously days 2-3), a 5-HT₃ antagonist (palonosetron 0.25 mg intravenously or 0.5 mg orally, or ondansetron 8 mg intravenously or 8 mg orally twice, or tropisetron 5 mg intravenously, all on day 1), and an NK₁ antagonist (fosaprepitant 150 mg intravenously, or aprepitant 130 mg intravenously, or oral aprepitant 125 mg day 1 then 80 mg days 2-3, or netupitant 300 mg orally day 1). EA was applied at Zusanli (ST36), Neiguan (PC6), Hegu (LI4), and Zhaohai (KI6) with insertion depths of 20 mm, 15 mm, 20 mm, and 5 mm respectively, using continuous wave mode at 2 Hz and current intensity ≤10 mA (tolerance-adjusted) for 30 minutes per session. Treatment started 1-2 hours pre-chemotherapy on day 1 and continued daily at 9:00-10:00 on days 2-4, totaling four sessions per cycle.

  • Placebo comparator
    sham acupuncture + standard quadruple antiemetic therapy

    The control group received sham electroacupuncture combined with the identical standard quadruple antiemetic regimen (drug components and dosages identical to the experimental group). The sham intervention protocol consisted of: (1) superficial needle insertion at non-acupoint locations adjacent to the authentic acupoints (ST36, PC6, LI4, and KI6); (2) attachment of non-functional electrodes using deactivated electroacupuncture devices with identical appearance to active units; while maintaining identical treatment duration (30 minutes/session) and schedule (pre-chemotherapy on day 1 followed by daily sessions on days 2-4) as the true electroacupuncture group.

Interventions

  • Deviceelectroacupuncture

    The acupuncturist applied needles at four acupoints: Zusanli (ST36), Neiguan (PC6), Hegu (LI4), and Zhaohai (KI6), with insertion depths of approximately 20 mm, 15 mm, 20 mm, and 5 mm respectively. Electrical stimulation was delivered in continuous wave mode at 2 Hz frequency with current intensity ≤10 mA (adjusted according to patient tolerance), administered for 30 minutes per session.

  • Drugstandard quadruple antiemetic therapy

    Olanzapine (2.5 mg orally daily, days 1-4), dexamethasone (10 mg intravenously day 1; 7.5 mg intravenously days 2-3), a 5-HT₃ antagonist (palonosetron 0.25 mg intravenously or 0.5 mg orally, or ondansetron 8 mg intravenously or 8 mg orally twice, or tropisetron 5 mg intravenously, all on day 1), and an NK₁ antagonist (fosaprepitant 150 mg intravenously, or aprepitant 130 mg intravenously, or oral aprepitant 125 mg day 1 then 80 mg days 2-3, or netupitant 300 mg orally day 1).

  • Devicesham electroacupuncture

    The same acupoints as the electroacupuncture group were referenced, but with sham acupuncture (minimal insertion at non-acupoint locations) and sham electrical stimulation, while maintaining the same treatment duration and course as the electroacupuncture group.

  • Drugstandard quadruple antiemetic therapy

    Olanzapine (2.5 mg orally daily, days 1-4), dexamethasone (10 mg intravenously day 1; 7.5 mg intravenously days 2-3), a 5-HT₃ antagonist (palonosetron 0.25 mg intravenously or 0.5 mg orally, or ondansetron 8 mg intravenously or 8 mg orally twice, or tropisetron 5 mg intravenously, all on day 1), and an NK₁ antagonist (fosaprepitant 150 mg intravenously, or aprepitant 130 mg intravenously, or oral aprepitant 125 mg day 1 then 80 mg days 2-3, or netupitant 300 mg orally day 1). All the antiemetic drugs used are the same as those in the true acupuncture group.

Primary outcomes

  1. The incidence of chemotherapy-induced gastrointestinal symptom clusters, including nausea, vomiting, poor appetite, and xerostomia, within 120 hours after chemotherapy.

    Time frame: 120 hours

Secondary outcomes

  1. Improvement in other gastrointestinal symptom clusters after the first cycle of chemotherapy.

    Time frame: 120 hours

  2. The incidence of no nausea during the acute and delayed phases following the first chemotherapy cycle.

    Time frame: 120 hours

  3. The incidence of no vomiting during the overall, acute, and delayed phases following the first chemotherapy cycle.

    Time frame: 120 hours

  4. Complete response rates in the overall, acute, and delayed phases following the first chemotherapy cycle.

    Time frame: 120 hours

  5. Complete protection rates in the overall, acute, and delayed phases following the first chemotherapy cycle.

    Time frame: 120 hours

  6. Quality of life assessed by the five-level EuroQol five-dimensional questionnaire (EQ-5D-5L).

    The EQ-5D-5L evaluates five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is scored from 1 ("no problems") to 5 ("extreme problems"), with health states expressed as 5-digit codes (e.g., 11111=no impairment; 55555=extreme impairment across all dimensions). Index scores were calculated using the Chinese value set (Luo et al., 2017), yielding a theoretical range of -0.391 (worse than death) to 1.0 (perfect health). The visual analogue scale (VAS) component records self-rated health status from 0 ("worst imaginable health") to 100 ("best imaginable health").

    Time frame: 120 hours

Other outcomes

  1. Exploratory multi-omics analysis of electroacupuncture's modulation on symptom clusters.

    Time frame: From enrollment through the entire chemotherapy cycle (up to 8 cycles, each cycle is 21 days; maximum 64 weeks)

  2. Association between electroacupuncture and pathological complete response rate in patients receiving neoadjuvant therapy.

    Time frame: From enrollment through the entire chemotherapy cycle From enrollment through the entire chemotherapy cycle (up to 8 cycles, each cycle is 21 days; maximum 64 weeks)
