[Analysis of Chemotherapy-Induced Nausea and Vomiting during Chemotherapy for Gastric Cancer].

BACKGROUND: Chemotherapy-induced nausea and vomiting(CINV)are typical side effects caused by chemotherapy. We analyzed CINV during first-line chemotherapy for gastric cancer. MATERIALS AND METHOD: Thirty-one patients who received first-line chemotherapy for gastric cancer were retrospectively assessed for CINV. RESULTS: The median age was 70 years, and the gender(male/female)was 23/8 cases. NK1 receptor antagonist, 5-HT3 receptor antagonist, and dexamethasone were used as antiemetic agents in 29 patients(94%). Sixteen patients(52%)had Grade 1 or higher nausea, and 6 patients (19%)had Grade 1 or higher vomiting, and complete control of nausea and vomiting was achieved in 21 patients(68%). Nausea was significantly more frequent in patients with liver metastasis(p=0.0008), but there was no significant difference in vomiting(p=1.0000). There was no significant difference in the occurrence of CINV between chemotherapy regimens or combination of olanzapine. CONCLUSION: During first-line chemotherapy for gastric cancer, 3 antiemetic agents were used in 94% of cases, and the complete control rate of CINV was 67.8%.
