Description of intervention(s) / exposure
This is not an interventional study but a feasibility study measuring patient reported outcomes (PROs) in the evaluation of side effects and toxicities from steroid use in patients with brain tumours or brain metastases or advanced cancer. Clinician's will rate patient toxicities from steroid use at baseline using Common Terminology Criteria for Adverse Events version 4. 50 patients will be recruited to the study with at least half (25) having a primary brain tumour (and 50 associated caregivers). The caregivers’ responses are collected in conjunction with those of the patients and are crucial for assessing the reliability of the measurements.

The duration of observation for each patient is 8 weeks with timepoints occuring at baseline, 2, 4 and 8 weeks. At each timepoint, questionnaires are required to be completed.

Outcomes
Primary outcome [1] 259360 0
To test the feasibility of using questionnaires to assess patient, clinician and caregiver rated side effects which may be related to dexamethasone
Timepoint [1] 259360 0
Patients who meet the inclusion criteria and their nominated caregiver will complete the Patient Reported Outcome (PRO) battery which comprises the Dexamethasone Symptom Questionnaire Chronic (DSQ-Chronic), acetazolomide toxicity questionnaire and European Organization for Research and Treatment of Cancer quality of life questionnaire: a shortened questionnaire for cancer patients in palliative care (EORTC QLQ-C15-PAL) at recruitment and again at 2, 4 and 8 weeks. Clinician will assess dexamethasone toxicity using Common Terminology Criteria for Adverse Events (CTCAE) v 4 criteria and rate patient's Karnofsky Performace Status (KPS) at baseline.
Secondary outcome [1] 265842 0
To evaluate the face validity of the DSQ-Chronic by evaluating the rate of completion and participant feedback at structured interview.
Timepoint [1] 265842 0
Paricipants will complete the DSQ-Chronic at baseline and then at 2, 4 and 8 weeks. The structured interview will also take place within 2 weeks after baseline (study start).
Secondary outcome [2] 265843 0
To evaluate the face validity of the acetazolamide toxicity questionnaire by evaluating the rate of completion and participant feedback at structured interview.
Timepoint [2] 265843 0
The acetazolomide questionnaires will be completed by patients at baseline and then at 2, 4 and 8 weeks after baseline.

The structured interview will also take place within 2 weeks after baseline.
Secondary outcome [3] 265844 0
To determine the point prevalence and severity of symptoms which may be attributable to dexamethasone.
Timepoint [3] 265844 0
This aspect concerns the statistical analysis and conclusions made from the data collected at the time points mentioned in the primary outcome (baseline, 2, 4 and 8 weeks)
Secondary outcome [4] 265845 0
To compare patient and caregiver rated dexamethasone related symptoms (prevalence and severity) to establish the likely reliability of proxy rating in future longitudinal interventional studies with participants with progressive brain tumours, some of whom may develop difficulty self-completing due to cognitive impairment
Timepoint [4] 265845 0
This aspect concerns the statistical analysis and conclusions made from the data collected at the time points mentioned in the primary outcome (baseline, 2, 4 and 8 weeks)
Secondary outcome [5] 265846 0
To compare patient and caregiver rated toxicity with clinician rated toxicity using CTCAE v 4 criteria
Timepoint [5] 265846 0
This aspect concerns the statistical analysis and conclusions made from the data collected at the time points mentioned in the primary outcome (baseline, 2, 4 and 8 weeks)
Secondary outcome [6] 265847 0
To assess the rate of recruitment of patients with primary brain tumour to inform the feasibility of phase II study
Timepoint [6] 265847 0
The rate of recruitment will be continually monitored during the course of the study up to completion of the recruitment target.
Secondary outcome [7] 265848 0
To test the feasibility of measuring patient, clinician and caregiver rated side effects which may occur with acetazolamide administration to determine baseline rates of these symptoms.
Timepoint [7] 265848 0
This aspect concerns the statistical analysis and conclusions made from the data collected at the time points mentioned in the primary outcome (baseline, 2, 4 and 8 weeks)
Secondary outcome [8] 265849 0
To assess the rate of recruitment of participants with primary brain tumours, recommenced on dexamethasone (at least 4 mg/day) and on a stable dose for at least 48 hours
Timepoint [8] 265849 0
The rate of recruitment will be continually monitored during the course of the study up to completion of the recruitment target.
