Multicenter Study Controlled Clinical Trial
Postmarketing surveillance study of OxyContin tablets for relieving moderate to severe postherpetic neuralgia pain.
To evaluate the efficacy and safety of OxyContin tablets(controlled-release oxycodone hydrochloride: 5, 10, 20, and 40 mg) in relieving moderate to severe postherpetic neuralgia (PHN) pain. ⋯ Controlled-release OxyContin tablets demonstrated fast onset of PHN pain control, superior efficacy in relieving both moderate and severe PHN pain, and a good safety profile.

This is a multicenter investigational survey conducted in 76 hospitals in Shanghai between July and August 2004. The objective was to investigate the cancer pain status and physicians' pain management capabilities in Shanghai. A total of 923 cancer patients involved in the investigation completed a questionnaire which included general condition, self-assessment of pain and questions of pain control knowledge. The study results were analyzed concerning: reason for cancer pain, type and intensity of cancer pain, treatment methods, patients' understanding of addiction, patients' request for pain treatment, and patients' and physicians' viewpoint on current cancer pain treatment.

Ovarian suppression has been used to treat hormone-responsive metastatic breast cancer in premenopausal women for over 100 years and is currently under continued evaluation for treatment in the adjuvant setting. In this article, ovarian suppression by surgery, radiation, and pharmacological therapy is discussed, including the risks, benefits, and efficacy of each strategy. The role of ovarian suppression in premenopausal women with early and advanced stages of breast cancer will be reviewed. It is hoped that this review will assist clinicians and their patients in selecting the appropriate therapy if ovarian suppression is indicated.

In order to evaluate the potential role of oxycodone in cancer pain management, neuropathic cancer pain was selected as a model for difficult pain syndromes. A nonsystematic, yet exhaustive, review of the literature provided the relevant evidence for the discussion. Ten randomized controlled trials (RCTs) and 5 open-label studies on oxycodone and cancer pain, 3 RCTs and 1 open-label study on oxycodone and neuropathic pain, and 2 RCTs on oxycodone and visceral pain were identified and reviewed. ⋯ The intrinsic difficulties in performing RCTs in cancer pain have traditionally justified the acceptance of drugs already known to be effective in benign neuropathic pain, in spite of insufficient evidence in malignant neuropathic pain. Therefore, a case is made for the development of specific guidelines for the management of both simple and complex cases of neuropathic cancer pain. An example of one of such clinical guidelines is provided, in which the role of oxycodone is particularly relevant given the existing evidence.
