Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study aimed to pilot the viability of a full scale randomised comparison of 2 steroid doses in malignant spinal cord compression, to establish safety of high dose dexamethasone in this setting in Australia, to test web registration and randomisation and to compare different functional outcome measures.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Malignant spinal cord compression (MSCC) is an uncommon condition with an estimated annual incidence of 2.5 per 100,000. It is a dreaded complication of malignancy because of the severe impact paralysis and sphincter disturbance has on quality and duration of survival.

Rat models have demonstrated the effectiveness of high doses of steroids. Only three randomised controlled trials (RCTs) have been published. The first compared radiotherapy to laminectomy plus radiotherapy in a series of 29 patients and failed to show any significant differences The widespread commonly used dose of Dexamethasone in Australia at that time was 16 mg/24 hr and the main concern for implementing higher doses was the toxicity profile reported in the few small randomised comparisons available at the time.In view of the conflict between standard Australian practice versus published (overseas) guidelines, a randomised comparison was proposed in Australia. This study was a pilot study initiated to determine the viability of a large trial, to pilot the use of web technology for trial conduct and to determine clinically useful outcome measures apart from simple ambulation rates.

Comparisons: Patients randomised to receive either 16mg/24hr or 96mg/24hr dexamethasone.
