简要总结
To investigate if topical amitriptyline 2%, ketamine 1%, and lidocaine 5% in pluronic lecitine organogel (AKL in PLO gel) can improve management of neuropathic pain from radiation skin reactions adjunctively or better than standard treatment.
详细描述
- Topical amitriptyline and ketamine and topical lidocaine alone have been shown to improve management of neuropathic pain in nonmalignant subjects. Anecdotal experience has shown improvement in use of all three topical drugs combined in radiation skin reactions. There currently is no research evidence for the use of all three compounded interventions. This study aims to target subjects with pain from radiation therapy who are not receiving adequate relief with standard interventions and may be eligible to receive this alternate intervention.
- Hypothesis:Topical AKL in PLO gel can effectively and safely reduce neuropathic pain experienced by patients with radiotherapy induced skin reactions.
- Justification: Standard treatment of painful radiation skin reactions such as moist desquamation consists of saline soaks, silver sulfadiazine and oral analgesics. However, sometimes the pain exceeds this standard intervention, patients are sulfa allergic or patients are intolerant to oral analgesics such as opioids. AKL in PLO gel is targeted for neuropathic pain and may be used alternatively to standard interventions. The participation rate will help to further estimate the feasibility of a larger sample size study to look at efficacy.

结局指标
主要结局
The primary outcome measure will to use the validated University of Washington Neuropathic Pain Scale (UWNPS) on all radiation skin reaction subjects requiring standard intervention.
时间窗: University of Washington Neuropathic Pain scale will be conducted at the time of assessment, every 2-5 days while on radiotherapy, week 2 and 6 weeks post radiotherapy.
次要结局
- Skin Toxicity Assessment Tool (STAT)(Presence of dry desquamation or worse on STAT at baseline assessment, complete STAT 30 minutes post application of cream, every 2-5 days while on radiotherapy, week 2 and 6 weeks after completing radiation therapy.)
