- The use of verbal category scales in assessing patient symptoms is evolving, but the extent to which reliability and precision are lost in using them as opposed to a visual analogue scale (VAS) remains uncertain. The present study analyzed the concordance between a four-point verbal category scale and a VAS in assessing nausea intensity in patients undergoing chemotherapy. The analysis of a total of 348 simultaneous ratings by 104 women over four cycles revealed good concordance between the scales. The means of the VAS ratings (range 0-100 mm) corresponding to the four verbal categories divided the scale in four almost equally large parts (no nausea = 0.7, mild = 24.8, moderate = 48.3, severe = 75.1). However, the VAS ranges were wide. On an individual level a one-step change in the verbal category was associated with an average change of 20 mm on the VAS. The choice of scale to use should be based on the need in the particular situation. When measuring intensity of nausea in patients, the VAS is a reasonable choice due to its possibly greater ability to detect changes over time. On the group level, findings on a four-point category scale and a VAS on the average seem similar.

- We investigated how residual tumour burden after cytoreductive surgery was related to the occurrence of acute and delayed nausea and vomiting in 101 ovarian cancer patients receiving their first chemotherapy course. The anti-emetic treatment included ondansetron combined with dexamethasone or placebo. After chemotherapy all patients received ondansetron only for 5 days. Two categories of tumour burden (TB) were formed according to the diameter of the greatest residual tumour (< 2 cm = minimal TB and > or = 2 cm = large TB). Self-reports of nausea and vomiting were obtained for 15 days. Other potential predictor variables were assessed and included in multivariate analyses. Patients with large compared with minimal TB had more delayed emesis, especially on days 2-7. They also had more acute nausea. The aggravating effect associated with large residual TB was more evident in patients > or = 55 years. During the second week after the chemotherapy the occurrence of nausea was higher in patients > or = 55 years than in those < 55 years. This was seen primarily in patients with large residual TB. Predictors for no delayed emesis at all were anti-emetic treatment with dexamethasone, minimal tumour burden, low neuroticism and no history of motion sickness. The increased risk of "persistent' delayed nausea and vomiting seen in older patients with large tumour burden may have important clinical implications and warrants further attention.

Journal article (peer-reviewed)abstract
- The introduction of serotonin receptor (5-HT3) antagonists has improved the control of acute nausea and vomiting induced by cancer chemotherapy, but they seem to have little or no effect on delayed symptoms. Corticosteroids are known to reduce both acute and delayed nausea and vomiting. The aim of the present study was to test the hypothesis that a single high dose of dexamethasone (20 mg), a long-acting corticosteroid, given after cisplatin and in addition to ondansetron (8 mg three times a day), would enhance the control of both acute and delayed nausea and vomiting. A group of 104 chemotherapy-naive ovarian cancer patients, scheduled for at least three cycles of combination chemotherapy including cisplatin (50 mg/m2), were randomly allocated to receive either dexamethasone or placebo in addition to ondansetron. Two-thirds of the patients received doxorubin and melphalan on the day before cisplatin and 1/3 received doxorubicin immediately before cisplatin. Unexpectedly we found, in all three chemotherapy cycles, that patients receiving dexamethasone suffered from more delayed nausea and vomiting than patients receiving placebo. In patients with no acute nausea or vomiting, the boomerang effect of dexamethasone could be seen on the first day after chemotherapy. In a follow-up study on 5 patients not included in the randomized trial, dexamethasone induced a pronounced reduction in urinary cortisol excretion on the day after chemotherapy with a return to normal excretion on day 2. It is concluded that a single high dose of dexamethasone does not seem appropriate for controlling delayed nausea and vomiting.
