Filter by:This study is planned to investigate the pain control status in cancer patients in 6 South East Asian countries through evaluation of prescription pattern of analgesics, satisfaction of pain control, quality of life and assessment of the adequacy of pain control and relationship among these factors in cancer patients with pain. Cancer pain is undermanaged and it is hoped that this study will be used as a reference for effective cancer pain management in these countries.
Pain is one of the most burdensome symptoms associated with cancer and its treatment, and opioids are the cornerstone of clinical pain management in cancer patients. Yet, individual patient responses to opioids vary widely, and the patient's genotype contributes to this variability. Specifically, cytochrome P450 2D6 (CYP2D6) genotype has important relevance for response to opioid analgesics that depend on CYP2D6 for bioactivation. Poor metabolizers (PMs) have lower concentrations of active metabolites of codeine (morphine), tramadol (O-desmethyltramadol), oxycodone (oxymorphone), and hydrocodone (hydromorphone), compared to extensive metabolizers (EMs). Morphine and O-desmethyltramadol have 200-fold greater affinity for the µ-opioid receptor than the parent compound, whereas oxymorphone and hydromorphone have 40-fold and 10-fold higher receptor affinity compared to their parent compounds, respectively. Consequently, PMs may fail to derive pain relief from these opioids compared to EMs. Interestingly, the occurrence of side effects may not differ between PMs and EMs so that while PMs may get little to no pain relief from certain opioid analgesics, they may still experience troublesome adverse effects. Intermediate metabolizers (IMs) are also expected to have reduced analgesic response based on their significant reduction in enzyme activity. Conversely, individuals with the UM phenotype may have toxic concentrations of active opioid metabolites, with reports of life-threatening toxicity and death. The µ-opioid receptor gene (OPRM1) is the primary binding site for endogenous opioid peptides and opioid analgesics, and may have additional contributions to opioid response. The investigators propose to examine the effect of CYP2D6 genotype-guided pain management on cancer pain control in study participants and the additional effect of the OPRM1 genotype on response to opioids.
The purpose of this study is to compare of difference in NRS scores from baseline to the completion of treatment (5 days) in patients with administration of morphine sulfate versus oxycodone hydrochloride.
Pain is the most common symptom (ca. 80% of patients) on German Palliative Care units and thus, pain control plays a central role in palliative care. Transcutaneous electrical nerve stimulation (TENS) is a complementary treatment option for patients who experience suboptimal pain control. However, the evidence for the efficacy of TENS in cancer patients is not unambiguous. The present study is a double blind, placebo-controlled cross-over trial with a short-term follow-up. The primary aim of this study is to evaluate the efficacy and safety of TENS for cancer pain reduction in advanced cancer patients. The secondary aim is the explorative identification of subgroups that benefit or do not benefit from TENS.
The purpose of this study is to determine whether tanezumab is effective in the treatment of cancer pain due to bone metastasis in patients already taking background opioid therapy.
34 adult (>18 years) cancer pain outpatients with Opioid base therapy because of pain and breakthrough pain or extreme pain on movement will be included in this prospective, randomized, double-blind crossover study. Over a period of 3 weeks patients will go through 3 treatment arms, each one lasting one week: Group A receives morphine drops and Placebo spray, Group B receives ketamine/chitosan spray nasal and Placebo drops and Group C receives morphine drops and ketamine/chitosan spray nasal. Primary endpoint is time to onset of action of intranasal ketamine compared with morphine drops. Secondary endpoint is the median numeric rating scale (NRS) improvement after using the spray or morphine or the combination of ketamine spray and morphine drops.
The purpose of this study is to compare efficacy of pain treatment with ITDD to efficacy of pain treatment with CMM in patients with pancreatic cancer pain.
The goal of this clinical research study is to learn if a cordotomy reduces pain in patients with unmanageable cancer pain. A cordotomy is a procedure, guided by computed tomography (CT) scans, that is performed on the spinal cord and is designed to reduce pain transmission.
The symptoms associated in advanced cancer patients and adverse events due to use of opioids have major influence on the state of health and quality of life of patients. The pain, in particular, is a symptom with severe negative impact and with a prevalence ranging between 33% and 64%, according to the stage of the disease, with values around 70-90% in advanced stages and metastatic. The use of opioids, however, is usually associated with the appearance of common adverse events as drowsiness/sedation, constipation, nausea/vomiting, and dizziness. Some effects are self-limiting in the time for the appearance of tolerance while others, as constipation persist. Several clinical studies have demonstrated that the association oxycodone-naloxone (OXN), which consists in the union between a molecule agonist and an antagonist of opioid receptors, reduced the constipation in the presence of unchanged analgesic efficacy compared to oxycodone alone.
The purpose of this study is to determine whether dexmedetomidine added to morphine is effective in the treatment of chronic cancer pain.
