ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of thalidomide in preventing nausea and vomiting induced by emetogenic cisplatin (CDDP) chemotherapy in patients with advanced non-small cell lung cancer.</p><p><b>METHODS</b>This study was carried out as a prospective, randomized control clinical trial. 61 patients with advanced non-small cell lung cancer were scheduled to receive chemotherapy (gemcitabin 1000 mg/m(2) i.v. gtt d1, 8 and CDDP 75 mg/m(2) i.v. gtt d1, GP regimen). The patients were randomly divided into a treatment and control groups. All patients in both groups received ramosetron 0.3 mg intravenously (i.v.) and metoclopramide 20 mg intramuscularly (i.m.) 30 min prior to chemotherapy to prevent nausea and emesis on day 1. In the treatment group, addition of thalidomide (50 mg p.o. bid) were administered on days 1 to 5 after the start of chemotherapy.</p><p><b>RESULTS</b>Acute nausea was effectively controlled in 74.2% of the patients in the control group and in 90.0% of treatment group. Acute vomiting was effectively controlled in 90.3% of the patients in the control group and in 93.3% of treatment group. No statistically significant differences showed in effective control of acute nausea and vomiting between the 2 groups (P = 0.108; P = 1.000). Delayed nausea was effectively controlled in 19.4% of the patients in control group and in 56.7% in the treatment group. Delayed vomiting was effectively controlled in 48.4% of the patients in control group and 76.7% in treatment group. Statistically there was a significant differences in effective control of delayed nausea and vomiting between the 2 groups (P = 0.003, P = 0.023). Both antiemetic regimens were well tolerated, and no significant difference was observed in adverse events between the 2 groups (P > 0.05).</p><p><b>CONCLUSION</b>Our results demonstrate that thalidomide is highly effective in controlling delayed nausea and vomiting episodes in patients induced by moderately emetogenic chemotherapy. Moreover, no serious toxic effects are induced by this treatment.</p>
