Over half of a group of 373 inpatients with advanced malignant disease were treated with corticosteroids for a variety of reasons. They received either prednisolone or dexamethasone, or replacement therapy with cortisone acetate. Forty percent of those receiving corticosteroids benefited from them. A higher response rate was seen when corticosteroids were prescribed for nerve compression pain, for raised intracranial pressure, and when used in conjunction with chemotherapy. No significant difference in efficacy was noted between the 2 drugs. The results, however, suggest that with a larger sample, dexamethasone would have been shown to be significantly better than prednisolone in the management of nerve compression pain. The incidence of side effects was broadly similar with dexamethasone and prednisolone. The most common side effect was oral candidosis and there was a highly significant relationship between the use of corticosteroids and the prescription of nystatin suspension. Dexamethasone was more likely than prednisolone to cause oro-pharyngeal candidosis. Dexamethasone was also associated with significantly more cases of psychological disturbance and hyperactivity. On the other hand, dexamethasone seems less likely to cause oedema, weight gain and dyspepsia. Corticosteroids were withdrawn because of side effects in only 11 patients (5%)--6 were receiving dexamethasone and 5 prednisolone. Dexamethasone has been adopted as the standard corticosteroid for terminal cancer patients at Sir Michael Sobell House.

The role of dexamethasone to reduce delayed emesis following highly emetogenic chemotherapy is proven, but there is less evidence of benefit after mild-moderately emetogenic regimens. Here, we develop and evaluate a Dexamethasone Symptom Questionnaire (DSQ) to assess the side effects of dexamethasone in the week after patients receive moderately emetogenic chemotherapy. The DSQ was first optimised with the aid of a focus group. Sixty patients receiving oral dexamethasone for prophylaxis of delayed emesis after moderately emetogenic chemotherapy for cancer completed and then evaluated the DSQ. Patients reported that the DSQ was clearly worded and addressed items important to them. Patients receiving dexamethasone reported moderate-severe problems with insomnia (45%), indigestion/epigastric discomfort (27%), agitation (27%), increased appetite (19%), weight gain (16%) and acne (15%) in the week following chemotherapy. The side effects of dexamethasone may outweigh its benefits when used with moderately emetogenic chemotherapy. A randomised, double-blind crossover trial is underway to determine the effect of dexamethasone on nausea and vomiting, and the impact of side effects of dexamethasone and of nausea and vomiting on quality of life.

Chemotherapy treatment can lead to delayed gastric emptying, early satiety, anorexia, nausea and vomiting, described collectively as the cancer-associated dyspepsia syndrome (CADS). Administration of ghrelin (GHRL), an endogenous orexigenic peptide known to stimulate gastric motility, has been shown to reduce the symptoms of CADS induced in relevant animal models with the potent chemotherapeutic agent, cisplatin. We examined the effects in the rat of cisplatin (6 mg/kg i.p.) treatment on the expression of GHRL and ghrelin receptor (GHSR) mRNAs in the hypothalamus and the stomach at a time-point (2 days) when the effects of cisplatin are pronounced. In addition, plasma levels of GHRL (acylated and total including des-acyl GHRL) were measured and the effect on these levels of treatment with the synthetic glucocorticoid dexamethasone (2 mg/kg s.c. bd.) was investigated. Cisplatin increased GHSR mRNA expression in the stomach (67%) and hypothalamus (52%) but not GHRL mRNA expression and increased the percentage of acylated GHRL (7.03+/-1.35% vs. 11.38+/-2.40%) in the plasma. Dexamethasone reduced the plasma level of acylated GHRL and the percentage of acylated GHRL to values below those in animals treated with saline alone (7.03+/-1.35% vs. 2.60+/-0.49%). Our findings support the hypothesis that an adaptive upregulation of the ghrelin receptor may occur during cancer chemotherapy-associated dyspepsia. This may have a role in defensive responses to toxic challenges to the gut. In addition, our results provide preliminary evidence for glucocorticoid modulation of plasma ghrelin levels.
