The effect of digital acupressure on chemotherapy-induced nausea in Indonesian patients with stages III-IV breast cancer

Abstract

Patients with breast cancer are reported to experience nausea and vomiting during neoadjuvant chemotherapy. Both remain the most troubling side effects of chemotherapy, even in the era of new antiemetic agents. Hence, our study aims to investigate the clinical outcome of acupressure in the prevention of acute chemotherapy-induced nausea (CIN) by evaluating the frequency and severity of nausea. This study was a randomized controlled trial consisting of 42 breast cancer patients, divided equally into two groups (experimental (acupressure) and control groups). Digital acupressure was performed at pericardium 6 (P6 or Neiguan) and stomach 36 (ST36 or Zusanli) points. Assessment of nausea was conducted by examining the frequency of nausea and measuring nausea-related subscores from the simulator sickness questionnaire (SSQ) and visual analog scale (VAS) within one hour after chemotherapy. Our study indicated that patients in the experimental group had significantly lower frequency and less severe nausea than those in the control group. In conclusion, acupressure effectively decreased the frequency and severity of nausea in breast cancer patients undergoing neoadjuvant chemotherapy. Acupressure could be implemented as an adjunct intervention in addition to antiemetic therapy for the prevention of CIN in breast cancer patients.
