Summary

Pain is a common symptom that is experienced by patients with advanced cancer. Whilst mild pain can usually be controlled with simple analgesics, more severe pain may require initiation of opioid analgesics. The World Health Organization (WHO) has developed a specific guideline for titration of analgesics. Known as the WHO Pain Ladder, patients who have severe pain despite non-opioid and weak opioid analgesics are advised to step up to level 3 - "Strong Opioids". Morphine is the most common opioid strong analgesic prescribed in Hong Kong. To the best of our knowledge, there is no formal opioid pain control guideline developed for cancer patients in Hong Kong. The prescription practices of various physicians who treat advance cancer patients, including oncologists and palliative care physicians have never been audited or standardized.

Furthermore, there are inherent issues with the administration of oral morphine. Currently, only one fixed concentration is available in a liquid formulation. Patients are known to have difficulties in receiving the appropriate dose. Accurate measurement of the volume required is extremely difficult, and many a times patients will report to have spilled the oral morphine during decanting, or will report that they have not been taking adequate doses because they are worried that they will decant too much into a spoon or syringe and overdose themselves.

Oxycodone is a semisynthetic strong opioid analgesic, which has recently been introduced to Hong Kong. It is formulated as a capsule, and again, 2 preparations (sustained-release (Oxycontin) and immediate release (Oxycodone IR)) are available. Inherent advantages include ease of administration; different groups have previously reported less adverse effects and better treatment compliance. However, to date, there has been no prospective 'head-to-head' comparison have ever been carried out comparing this with the traditional, well-accepted methods.

The purpose of this study is to assess whether or not the use of Oxycontin and Oxycodone IR may be superior to traditional medication choices and schedules in terms of time required for onset of pain control, the side effect profile, patients' tolerability and compliance to treatment. Interestingly, through this randomized open-label prospective study, we also aim to capture information on current opioid prescription practices by clinicians who manage patients with advanced cancers, which will be useful for us to consider the establishment of territory-wide treatment guidelines at a later juncture.
