Abstract

Background: Considering the incidence and prevalence rates of gastric cancer in Mazandaran Province of Iran, this research was performed to evaluate the efficacy and safety of olanzapine in symptom relief and quality of life (QOL) improvement of gastric patients receiving chemotherapy.

Materials and methods: This clinical trial was conducted on thirty new cases of gastric cancer patients whose treatment protocol was planned on chemotherapy and were allocated into two groups by simple random sampling. Intervention group (15 patients) received olanzapine tablets (2.5-10 mg/day) a day before the beginning of chemotherapy; in the 1st day of chemotherapy to 8 weeks after chemotherapy, besides the routine treatment regimens. The control group received only the routine treatment regimens. The patients were followed for 8 weeks after intervention. All of the patients were assessed with Hospital Anxiety and Depression Scale (HADS) and WHO-QOL-BREF questionnaires; further, Rhodes index was used to evaluate nausea and vomiting (N/V) status.

Results: All the recruited patients continued the allocated interventions (no lost to follow-up). N/V decreased in the case group, but the difference was not statistically significant (P = 0.438). The patients' appetite and body mass index increased (P = 0.006). Anxiety and depression subscales of HADS had significant differences between the two groups (P < 0.001) in the 4th and 8th week after treatment. Among the different subdomains of QOL, only physical health improved significantly after intervention (P < 0.05), but no significant difference was observed in other subdomains and also total QOL score (P > 0.05). No significant increase was observed in fasting and 2-h postprandial blood glucose and lipid profile (P > 0.05).

Conclusion: Olanzapine can be considered as an effective drug to increase appetite and decrease anxiety and depression in patients with gastric cancer.
