To investigate the effect of hangeshashinto to relieve chemotherapy-induced oral mucositis
Patients were to gargle three times daily with 2.5 g hangeshashinto (TJ-14) in 50 ml of water and rinse the oral cavity for about five seconds. Patients were instructed not to swallow it and not eat or drink anything for 30 minutes. Patients who received the intervention were compared to patients who did not. Measurements were done at baseline and at eight weeks.
No significant differences in maximum grade of mucositis or daily morphine dose existed. Oral intake and body weight were improved in those who took the hangeshashinto, but no comparative information on this measure from the control group was provided. The radiation completion rate was higher in the treated group (p = 0.045). Twenty-five percent of patients would not continue to use the gargle because of the bitter taste, nausea, vomiting, and refusal to wait 30 minutes before eating.
The findings do not show a benefit of hangeshashinto gargle on mucositis severity or associated pain.
This study did not show the effectiveness of hangeshashinto to prevent or reduce the severity of oral mucositis in patients with head and neck cancer receiving combined radiation and chemotherapy. Multiple report limitations are noted.
