A complex case report highlights the critical link between managing opioid use disorder (OUD) and the successful treatment of advanced cancer. The patient, a 41-year-old female facing frostbite, heart failure, stroke, and stage IV vulvar and anorectal cancer, also battled a 20-year history of opioid use.
The primary challenge was safely managing her OUD, pain, and withdrawal symptoms alongside intensive cancer care, including ostomy placement, radiation, and chemotherapy. Initial treatment with methadone was halted due to QTc prolongation concerns, leading to a switch to buprenorphine. However, relapse and uncontrolled pain necessitated a multidisciplinary reassessment.
Cardiology ultimately supported a return to methadone, recognizing its necessity for patient engagement in both OUD and cancer treatment. The patient was stabilized on methadone, gabapentin, and duloxetine, with additional therapies for various pain types.
Housing instability significantly complicated the patient's care, leading to nine hospital readmissions within six months. Barriers to transportation and daily treatment access made discharge planning extremely difficult.
Advocacy from addiction medicine, palliative care, and oncology teams secured prolonged hospitalization for treatment. The report emphasizes that for patients with OUD, advanced malignancy, and unstable housing, individualized planning, shared decision-making, and coordinated multidisciplinary care are essential to prevent treatment disruption.
