Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background: Chemotherapy-induced nausea and vomiting (CINV) is a common and burdensome side-effect of emetogenic chemotherapy. CINV affects both the patient's quality of life and induces high costs within the health-care system. Many patients are interested in acupuncture, despite weak scrientific evidence for its effects beside non-specific effects. Few credibly sham-controlled studies have previously been conducted. The therapist's care and communication during acupuncture as well as during standard care may induce non-specific effects, such as placebo effects, potentially driven by the patient's expectations. It is not known if the type of communication, in terms of how positive the therapist communicates regarding expected effects, affects the effect of antiemetic treatments.

Aims: To investigate if CINV, treatment expectancy and quality of life differ between patients who receive A) standard care including antiemetics, B) standard care plus sham acupuncture or C) standard treatment plus genuine acupuncture by a therapist who emphasizes the positive expected outcomes of the treatment, compared to a therapist who communicates neutral regarding the expected outcomes.

Procedure: The eligible patients will be randomized to A) standard antiemetic treatment or to B) standard antiemetic treatment plus sham acupuncture or C) standard antiemetic treatment plus genuine acupuncture. Within the three groups, the patients are randomized to receive either neutral or positive communication from the therapist during the treatment.

Outcome measures: The primary outcome is intensity of nausea within the five days after the chemotherapy session in patients receiving positive or neutral communication. Data collection of nausea and vomiting, expectations, and quality of life is performed at baseline the day before the studied chemotherapy session, during 10 days after the studied chemotherapy session, and at a follow-up ten days after the last chemotherapy session.

Procedure: Patients undergoing chemotherapy for cancer at three Swedish oncology departments will receive written and oral study information and are screened for study criteria. The eligible patients will be randomized to A) standard antiemetic treatment or to B) standard antiemetic treatment plus sham acupuncture or C) standard antiemetic treatment plus genuine acupuncture. Within the three groups, the patients are randomized to receive either neutral or positive communication from the therapist during the treatment.

Outcome measures: The primary outcome is intensity of nausea within the five days after the chemotherapy session in patients receiving positive or neutral communication. Data collection of nausea and vomiting, expectations, and quality of life is performed at baseline the day before the studied chemotherapy session, during 10 days after the studied chemotherapy session, and at a follow-up ten days after the last chemotherapy session.

Qualitative interviews regarding the patients' experiences of the communication with the professionals are conducted with a strategicaly selected group of patients from all randomization combinations. The selection aims to provide heterogenicity.

All other care providers beside the acupuncture/sham providing therapists are blinded to randomization group. For example, care providers providing the standard antiemetic treatment and the chemotherapy per se are blinded regarding randomization group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard care (A)

Standard antiemetic treatment (A) with neutral communication (A1) or positive communication (A2)

Group Type OTHER

Standard care

Intervention Type OTHER

A) Standard antiemetic treatment means receiving ordinary antiemetic medications. Within the group, the patients will be randomized to two communication types: 1) neutral communication or 2) strengthened positive communication regarding expected antiemetic effects of their treatment, using a standardized communication model.

Sham acupuncture (B)

Standard antiemetic treatment plus Sham acupuncture (B) with neutral communication (B1) or positive communication (B2)

Group Type PLACEBO_COMPARATOR

Sham acupuncture

Intervention Type DEVICE

B) Sham acupuncture is administered bilaterally to a non-acupuncture point two body-inches proximal and one body-inch radial from PC6 using the telescopic Park Sham Device. The sham-needle is blunt and glides upward into its handle instead of penetrating. Marking tubes hold the needle in place. The therapist gives an illusion of manipulating the needle by turning it three times until it touches the skin, but no specific needle sensation ("deqi") will occur. Within the group, the patients will be randomized to two communication types: 1) neutral communication or 2) strengthened positive communication regarding expected antiemetic effects of their treatment, using a standardized communication model.

Genuine acupuncture (C)

Standard antiemetic treatment plus Genuine acupuncture (C) with neutral communication (C1) or positive communication (C2)

Group Type EXPERIMENTAL

Genuine acupuncture

Intervention Type DEVICE

C) Acupuncture will be administered bilaterally to the standard antiemetic point PC6 located two body-inches proximal of the wrist crease, between the tendons of palmaris longus and flexor carpi radialis. Sharp acupuncture needles will be inserted into a depth of a half body-inch. The needles will be manipulated three times (at the start, middle and end of the treatment session) by twirling and lifting until deqi occurres. Within the group, the patients will be randomized to two communication types: 1) neutral communication or 2) strengthened positive communication regarding expected antiemetic effects of their treatment, using a standardized communication model.
