| Abstract: | The potential of steroid sparing from day 2 onward is reported in anthracycline-containing regimens for breast cancer treatment. We evaluated whether the reduction of dexamethasone (DEX) dose from 9.9 to 6.6 mg on day 1 is possible in anthracycline-containing treatments. Patients receiving anthracycline-containing regimens were divided into control (9.9 mg DEX on day 1) and reduced (6.6 mg DEX on day 1) groups, and retrospectively evaluated. The complete response (CR) rate and the incidence and severity of nausea, vomiting, anorexia, and fatigue were evaluated. The CR rate in the acute phase (day 1) was 63.1% and 38.1% in the control and reduced groups, respectively, with significant difference (P = 0.01) between the groups. However, no difference was found in the delayed phase (days 2-7). The incidence of anorexia and vomiting during treatment was not statistically different. Severity of nausea tended to, but not statistically, worsen while anorexia significantly worsened in the reduced group. Multivariate analysis suggested that patients < 55 years, with non- or less-alcohol drinking habit (< 5 days/week), and administered reduced-DEX dosage on day 1, have a higher risk of acute nausea development. Thus, reducing day 1 DEX dose in anthracycline-containing regimens is not suitable for acute nausea management. |
