Background: Corticosteroids are often used to treat fatigue and anorexia, but occasionally produce delirium. Information on the predictors of delirium in corticosteroid-treated cancer patients remains limited. Objective: To identify potential factors predicting the development of delirium in corticosteroid-treated cancer patients. Design: An exploratory, multicenter, prospective, observational study. Setting/Subjects: Inclusion criteria for this study were patients who had metastatic or locally advanced cancer and a fatigue or anorexia intensity score of 4 or more on a 0-10 Numerical Rating Scale. Measurement: Univariate and multivariable analyses were performed to identify the predictors of delirium diagnosed by the Confusion Assessment Method (CAM) within three days of initiation of corticosteroids. Results: Among 207 patients administered corticosteroids, 35 (17%; 95% confidence interval [CI] 12%-23%) developed at least one episode of delirium diagnosed by the CAM. Factors predictive of the development of delirium were as follows: Palliative Performance Scale ≤20, Eastern Cooperative Oncology Group Performance Status (ECOG PS) = 4, the Support Team Assessment Schedule (STAS) score of drowsiness >1, concurrent opioid use, parenteral hydration volume ≤500 mL, and the absence of lung metastasis. A multivariable analysis identified the independent factors predicting responses as ECOG PS = 4 (odds ratio [OR] 4.0; 95% CI 1.7-9.3), STAS score of drowsiness >1 (OR 3.4; 95% CI 1.4-8.2), and concurrent opioid use (OR 3.7; 95% CI 1.0-13). Conclusion: Delirium in corticosteroid-treated advanced cancer patients may be predicted by PS, drowsiness, and concurrent opioid use. Larger prospective studies are needed to confirm these results.

Background: Although corticosteroids are commonly used for symptom relief in the treatment of patients with advanced cancer, few studies have addressed nationwide physician-reported practices and attitudes toward corticosteroid therapy in palliative care settings. Design and Subjects: To clarify physician-reported practices and attitudes toward corticosteroid therapy for anorexia, fatigue, and dyspnea, a 15-item questionnaire was mailed to all 178 certified palliative care units in Japan. Results: In total, 124 physicians returned questionnaires (response rate of 70%). The median percentage receiving corticosteroids among all terminally ill cancer inpatients was 80% (fatigue, 80%; anorexia, 80%; dyspnea, 80%). Physicians reported varying methods and attitudes regarding corticosteroid use in palliative care settings. Regarding withdrawal when patient death was imminent, 46% of respondents usually abruptly ceased corticosteroid use, while 33% reduced but did not stop administration, and 21% neither stopped nor reduced corticosteroids. As for dosage, 47% of physicians selected a minimum daily dose for fatigue <2 mg, while 51% chose 2-4 mg. As for administration period, 50% started administering corticosteroids for dyspnea regardless of the prognosis, while 30% regarded a predicted survival of less than 3 months to be an indication for corticosteroid treatment. For side effect management, 48% did not principally prescribe corticosteroids for patients with hyperactive delirium, while 44% cautiously prescribed corticosteroids. Conclusion: The use of corticosteroids is very common in Japanese palliative care units, but physicians reported varying practices and attitudes regarding administration protocols. Future studies are needed to determine the standard treatment protocol for corticosteroid use in the terminally ill. [ABSTRACT FROM AUTHOR]

Background and Methods: Corticosteroids are commonly used for symptom relief in the treatment of patients with advanced cancer. Consistent efficacy of corticosteroid treatment in palliative care remains controversial. A cross-sectional anonymous survey was mailed to representative managing physicians in certified palliative care units in Japan to clarify the physician-perceived efficacy of steroid treatment on anorexia, fatigue, and dyspnea in terminal cancer patients, to clarify physicians' experience of side effects of corticosteroid use, and to determine the Japanese palliative care physician-reported predictive factors for efficacy and lack of efficacy. Results and Conclusions: Many Japanese palliative care specialists perceived that corticosteroids are effective for each of the symptoms, are aware of the prevalence and importance of serious adverse effects, and predict the effectiveness of steroid therapy by etiological factors.
