Objective: To observe the effect of acupuncture in different time on nausea and vomiting induced by chemotherapy of lung cancer.
Methods: A total of 150 patients with chemotherapy for lung cancer were randomized into a No.1 observation group, a No.2 observation group and a control group, 50 cases in each one. Excluded the dropped-off cases, finally, there were 49 cases in the No.1 observation group, 44 cases in the No.2 observation group and 47 cases in the control group. In the control group, 30 min before chemotherapy, the slow intravenous injection with tropisetron hydrochloride was used, 5 mg each time, once a day for 3 days. In the No.1 observation group, 30 min before chemotherapy, the slow intravenous injection with tropisetron hydrochloride was given combined with acupuncture. The acupoints selected were Zusanli (ST 36), Zhongwan (CV 12) and Neiguan (PC 6). The needles were retained for 30 min. The treatment was given once a day for 3 days totally. In the No.2 observation group, 30 min before chemotherapy, the slow intravenous injection with tropisetron hydrochloride was used, and 30 min after chemotherapy, acupuncture treatment was exerted. The acupoints and needling method were same as those in the No.1 observation group. Before and after treatment, the digestive reaction score, Karnofsky performance status scale (KPS) score and white blood cell count were all observed in the three groups. Additionally, the therapeutic effect and adverse reaction were observed and the therapeutic effect was compared among the treatment with acupuncture in different time.
Results: On the 2nd day of chemotherapy, the effective rates were 85.7% (42/49) and 75.0% (33/44) in the No.1 observation group and the No.2 observation group respectively, both higher obviously than 68.1% (32/47) in the control group (<0.05), and the effective rate in the No.1 observation group was higher obviously than the No.2 observation group (<0.05). On the 3rd day of chemotherapy, the effective rates were 81.6% (40/49) and 61.4% (27/44) in the No.1 observation group and the No.2 observation group respectively, both higher obviously than 57.5% (27/47) in the control group (<0.05), and the effective rate in the No.1 observation group was higher obviously than the No.2 observation group (<0.05). Compared before treatment, the KPS scores after treatment were obviously lower in the three groups (<0.05), and the decreased value of KPS score in the No.1 observation group was much lower than the control group and the No.2 observation group (<0.05). After 3-day chemotherapy, the white blood cell count was all reduced in each group, but the decreased value was not different statistically among the groups (>0.05).
Conclusion: Acupuncture combined with the slow intravenous injection with tropisetron hydrochloride achieve the satisfactory effect of prevention and treatment for vomiting induced by chemotherapy of lung cancer. The acupuncture intervention before chemotherapy greatly improves the effect on the nausea and vomiting induced by chemotherapy of lung cancer.
