title: Effectiveness of serotonin-receptor antagonist antiemetic therapy over successive courses of carboplatin-based chemotherapy.
abstract: OBJECTIVE
  There are extremely limited data available in the general oncology or gynecologic cancer literature to document the effectiveness of antiemetic therapy over multiple courses of cytotoxic chemotherapy.
  
  
  METHODS
  To examine this highly clinically relevant issue, we analyzed the complete treatment course of patients with gynecologic cancers receiving carboplatin-based chemotherapy regimens who had participated in one of four institutional serotonin-receptor antagonist antiemetic trials, which had specifically evaluated the benefits of such therapy during only the first treatment course. Medical records were reviewed to examine the development of emesis during subsequent chemotherapy treatment cycles.
  
  
  RESULTS
  The 91 patients included in this analysis received a median of 6 courses (range 1-18) of carboplatin (initial AUC dose 4, 5, and 6 in 29, 29, and 32 patients, respectively). All received ondansetron or granisetron plus dexamethasone with every treatment course. Complete control of emesis (no acute or delayed nausea or vomiting) was experienced by 56 (62%) patients during every cycle. Conversely, 20% of women noted one or more episodes of nausea without vomiting and 19% developed at least one incidence of vomiting. In no case was emesis considered to be severe (grade 3), and no patient required either discontinuation of carboplatin or a dose reduction due to the development of emesis.
  
  
  CONCLUSIONS
  In the large majority of patients, serotonin-receptor antagonist antiemetic therapy, administered in combination with dexamethasone, is highly effective over multiple courses in preventing significant carboplatin-induced nausea and vomiting.
