However, little is known about patients previously diagnosed with OUD who develop cancer and how to manage both OUD symptoms and control pain.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951523001293_sec2b\"><jats:title>Methods<\/jats:title><jats:p>The present case series deals with this subpopulation and proposes a dose escalation of methadone to control both the cancer-related pain and drug addiction symptoms.<\/jats:p><\/jats:sec><jats:sec id=\"S1478951523001293_sec3c\"><jats:title>Results<\/jats:title><jats:p>This approach is peculiar because methadone is not used as a first-line treatment in cancer pain management and is not often used as a second-line treatment as well.
