title: Transcutaneous electrical nerve stimulation as an adjunct for controlling chemotherapy-induced nausea and vomiting in gynecologic oncology patients.
abstract: BACKGROUND
  To evaluate the efficacy of a miniaturized portable transcutaneous electrical nerve stimulation (TENS) unit (ReliefBand) as an adjunct to standard antiemetic therapy for controlling nausea and vomiting induced by cisplatin-based chemotherapy in gynecologic oncology patients.
  
  
  METHODS
  Forty-two patients were enrolled in a randomized, double-blind, placebo-controlled parallel-subjects trial with a follow-up crossover trial. All patients received a standardized antiemetic protocol, then wore the ReliefBand continuously for 7 days.
  
  
  RESULTS
  Thirty-two patients were evaluable for the parallel-subjects component, 16 in each group. The percentage of patients with absent or minimal nausea was 59% overall, which was similar to that for both the active (56%) and placebo (62%) groups. The incidence and severity of nausea and vomiting was similar for each group. Eighteen patients completed two consecutive cycles and were evaluable for the crossover component. The average age of the crossover patients and their dose intensity were comparable with those of the overall study population (56.3 versus 58.6 years and 22.7 versus 22.7 mg/m2/week, respectively). The percentage of cycles with absent or minimal nausea was 47% overall, which was similar to that of the active (50%) and placebo (44%) cycles. However, the severity of nausea was significantly lower in the active cycles during days 2 to 4. Patients averaged less than one episode of vomiting daily in each cycle.
  
  
  CONCLUSIONS
  The ReliefBand is an effective adjunct to standard antiemetic agents for controlling nausea induced by cisplatin-based chemotherapy in gynecologic oncology patients.
