Active clinical trials for "Cancer Pain"

The purpose of this study is to determine the prevalence of breakthrough cancer pain and characterize breakthrough cancer pain in an unselected, representative cohort of cancer outpatients with or without pain who attend consultations.

The aim of the project is to investigate opioid-induced constipation (OIC) in a real world / diverse group of patients with cancer. The objectives of the project are to determine: a) prevalence of OIC; b) clinical features / impact of OIC; c) management of OIC.

The purpose of this study is to show the clinical usefulness of fentanyl matrix by measuring satisfaction with pain treatment after administering fentanyl matrix in patients whose pain was not controlled sufficiently with the previous analgesic use in real practice at the investigator's discretion.

This study aims at finding degree of adherence of patients to their chronic pain medication prescriptions containing opioid e.g. Morphine, using Morisky Medication Adherence Scale 8, self- reported questionnaire. Also relationship of various demographic, disease related and opioid related factors to medication adherence.

The methadone is an useful opioid for the cancer pain treatment, mostly used in second or last line during the opioid rotation. The Methadone had an anti-MNDA effect, and clinicians agree that the methadone could have an effect in neuropathic cancer pain. During a previous study the investigators find that the pain was still improving after the week 2, but they had only a small number of patients still included at this stage and they cannot conclude. The investigators decide to follow up systematically all the patients undergoing a methadone treatment for cancer pain, at day 28, to study the hypothesis about the long-term pain improvement.

The study aims to describe and quantify pain related to metastatic bone disease. The study will include 50 subjects with disseminated breast cancer and 20 healthy subjects. The pain will be described and quantified through (1) pain specific questionnaires, (2) quantitative sensory testing that assess sensory changes to cold, heat and mechanical stimulation of the skin overlying the metastatic site, and (3) conditioned pain modulation that investigates impairment of the endogenous inhibitory pain pathway in humans.

This research study is being done to understand how patients with chronic cancer pain take their long-acting opioid medications, and to develop an intervention to enhance cancer pain management.

As seen worldwide, cancer incidence is increasing in Latin America achieving an amount of 1.3 million new cases annually.1 In addition, it is expected that up to 70% of patients with cancer will experience pain2, one of the most distressing symptoms in patients with advanced cancer. And despite of advances in cancer therapies, opioids remain the mainstay treatment of cancer-related moderate-to-severe and end-of-life pain.3 However, concerns regarding opioid prescriptions have emerged for reasons like the risk of misuse and the possibility of cancer progression. In the last decades, an increase in consumption of opioids as well as in opioids-related deaths generating the so called 'opioid crisis'. This rise is mainly due to abuse / addiction of opioids. Consequently, oncologic patients are at risk for abuse, as well as for aberrant use, which can complicate the course of cancer treatment.4 5 Another feature of opioids use in cancer patients is that it may contribute to disease progression. Experimental studies suggest that opioids can may lead to immunosuppression and tumor progression or recurrence.6-8 On the other hand, retrospective analysis of clinical data shows conflicting results and trials are lacking.

This cross-sectional study, utilizing two sets of questionaire designed for patients and physicians respectively, aims at the epidemiology, the clinical features, and the current status of evaluation and management of lung cancer related pain in 20 participating hospitals in Northern China.
