NCT04563013

Brief Summary

Patients diagnosed with breast cancer who received assisted radiotherapy were recruited and the transcutaneous auricular vagus nerve stimulation (taVNS) was applied. The aim of of study is : 1) to study whether taVNS could improve the patient's fatigue, quality of life under radiotherapy or chemotherapy; 2) to investigate the effects of taVNS on the levels of patients' lymphocyte subsets and proinflammatory cytokines.

Outcome Measures

Primary Outcomes (1)

  • the score of fatigue at 1 month

    For fatigue degree evaluation, the Brief Fatigue Inventory (BFI) was used. The score of fatigue in two groups will be evaluated by BFI and will be compared. The scale uses the 11-point scoring method, whereby 0 points indicates no fatigue and 10 points the most severe fatigue. A higher score indicates more severe fatigue. The BFI included three fatigue severity items and six fatigue interference items. Three fatigue severity items ask patients to rate the severity of their fatigue at its "worst", "usual" and "now" during the past 24 h and another six fatigue interference items describe how much fatigue has interfered with different aspects of the patient's life during past 24 h, including general activity, mood, walking ability, normal work, relationships with other people and enjoy of life.

    The taVNS treatment lasted about five weeks, data were collected at 1 month after the end of the taVNS treatment

Secondary Outcomes (6)

  • the scores of HADS at End and at 1 month

    The taVNS treatment lasted about five weeks, data were collected at the end of RT and taVNS treatment and 1 month after the end of taVNS treatment

  • the scores of PSQI at End and at 1 month

    The taVNS treatment lasted about five weeks, data were collected at the end of RT and taVNS treatment and 1 month after the end of taVNS treatment

  • the scores of EORTC QLQ-C30 at End and at 1 month

    The taVNS treatment lasted about five weeks, data were collected at the end of RT and taVNS treatment and 1 month after the end of taVNS treatment

  • the change of cell counts of blood cells from baseline to End and to 1M.

    The taVNS treatment lasted about five weeks, data were collected at the end of RT and taVNS treatment and 1 month after the end of taVNS treatment

  • the change in IL-6 level from baseline to End and to 1M.

    The taVNS treatment lasted about five weeks, data were collected at the end of RT and taVNS treatment and 1 month after the end of taVNS treatment

  • +1 more secondary outcomes

Study Arms (2)

Sham taVNS

SHAM COMPARATOR

The participants under conventional radiotherapy were applied with sham taVNS at the left tragus with the power off for 30min. The intervention would last until to the end of conventional radiotherapy.

Device: Transcutaneous vagus nerve stimulation

taVNS

ACTIVE COMPARATOR

For taVNS group, the electrodes were attached to the tragus of left ear after skin preparation with an alcohol pad. The stimulation current was a single-phase rectangular pulse with the following stimulation parameters: duty circle: 60 s "on" periods and 10 s "off" periods; frequency: 30 Hz; pulse width: 200 μs; pulse amplitude of 0.5 mA to 1.5 mA; stimulation time:30 min.

Device: Transcutaneous vagus nerve stimulation

Interventions

the transcutaneous vagus nerve stimulation was conducted by ear clip with cathode and anode placed at the tragus for 30 min.
