Spots Global Cancer Trial Database for Real-life Observational Study of Cancer Pain Management With Methadone in Patients Inadequately Relieved by Other Level 3 Opioids.

Study Description

Brief Summary: Study rational. Methadone is a distinctive opioid because of its pharmacological characteristics and its multiple modes of action, reinforcing its therapeutic value in managing advanced cancer pain, particularly in cases with a neuropathic component. However, the complex pharmacodynamics of methadone makes its prescription sometimes challenging. There is a wide inter-individual variability of its half-life. This long half-life is a valued characteristic for the management of patients treated for an addictive disorder. However, in the context of pain management, it greatly complicates the switch from and to another opioid, accentuating the risk of overdose. This is the reason why LBR, willing to improve his knowledge about Methadone in real life clinical practice wants to performe this study. We anticipate that most patients will receive one of the above-described protocols, but we must anticipate that other protocols may be used in clinical practice in the absence of specific recommendations. Therefore it is of utmost relevance to describe the safety when initiating treatment with Zoryon® during the crucial period from D1 until the day of optimal dosage is determined (DOD) as the clinical practice may vary from a practician to another, and then until the routine follow-up visit one month after initiation of the treatment (D28).

Detailed Description: To describe the occurrence of overdose and QTc prolongation in patients initiating a treatment with Zoryon® for intractable cancer pain not adequately relieved from other level 3 opioids, from the day of instauration (D1) to the day of determination of the optimal dose for the patient (DOD: Day of Optimal Dosage (DOD): the dosage of Zoryon® will be considered optimal after two consecutive days without modification to the posology (usually within the first week) AND pain relief for the patient.
