Randomized Controlled Trial Clinical Trial
Randomized, double-blind, cross-over trial comparing safety and efficacy of oral controlled-release oxycodone with controlled-release morphine in patients with cancer pain.
Use of oxycodone for chronic cancer pain has been hampered by its short elimination half-life. This study was designed to compare the efficacy and safety of controlled-release formulations of oxycodone and morphine for cancer pain. ⋯ Controlled-release oxycodone is as safe and effective as controlled-release morphine in the treatment of cancer pain.

Randomized Controlled Trial Multicenter Study Clinical Trial
Comparison of controlled-release and immediate-release oxycodone tablets in patients with cancer pain.
This study compared the clinical efficacy of oxycodone hydrochloride controlled-release (CR) tablets administered every 12 hours with immediate-release (IR) oxycodone tablets administered four times daily in patients with cancer-related pain. ⋯ CR oxycodone every 12 hours was as effective as IR oxycodone four times daily in managing moderate to severe cancer-related pain and was associated with fewer reports of adverse events.

To define the dose ratio between morphine and methadone in relation to the previous morphine dose and the number of days needed to achieve the same level of analgesia in a group of patients with advanced cancer with pain who switched from morphine to oral methadone. ⋯ The results of our study confirm that methadone is a potent opioid, more potent than believed. Caution is recommended when switching from any opioid to methadone, especially in patients who are tolerant to high doses of opioids.

To identify prognostic variables that predict for improved biochemical and local control outcome in patients with localized prostatic cancer treated with neoadjuvant androgen deprivation (NAAD) and three-dimensional conformal radiotherapy (3D-CRT). ⋯ For patients treated with NAAD and high-dose 3D-CRT, pretreatment PSA, preradiotherapy PSA nadir response, and clinical stage are important predictors of biochemical outcome. Patients with NAAD-induced PSA nadir levels greater than 0.5 ng/mL before radiotherapy are more likely to develop biochemical failure and may benefit from more aggressive therapies.

Randomized Controlled Trial Multicenter Study Clinical Trial
Dose-titration, multicenter study of oral transmucosal fentanyl citrate for the treatment of breakthrough pain in cancer patients using transdermal fentanyl for persistent pain.
Supplemental, "as-needed," administration of an opioid is a common approach to the problem of breakthrough pain in cancer patients. Oral transmucosal fentanyl citrate (OTFC) is undergoing investigation as a new treatment for breakthrough pain. The primary purpose of the study was to demonstrate that a single-unit dose of OTFC can safely and effectively treat breakthrough pain. A secondary goal was to determine appropriate dosing guidelines. ⋯ Most patients find a single OTFC dosage that adequately treats breakthrough pain. The optimal dose is found by titration and is not predicted by around-the-clock dose of opioids.
