What is the optimal palliative management for a patient with advanced pancreatic adenocarcinoma and diffuse liver metastases causing liver failure who is already receiving best‑supportive care?

Palliative Management of Metastatic Pancreatic Cancer with Liver Failure

For a patient with metastatic pancreatic adenocarcinoma, liver metastases causing liver failure, and already on best supportive care, the immediate priority is aggressive symptom control with opioid titration for pain, endoscopic biliary stenting if obstructive jaundice is present, and urgent hospice referral given the expected survival of 2-8 weeks. 1, 2

Immediate Hospice Transition

• Hospice discussion and referral should occur immediately when the patient presents with extensive disease too ill to tolerate treatment or has progressive disease without reasonable further anticancer options. 3
• With liver failure from metastatic disease and no active anticancer treatment, expected survival is 2-8 weeks, making hospice the appropriate care setting. 2
• The focus must shift entirely to comfort measures, symptom management, and end-of-life planning, as curative or life-prolonging treatment is not feasible. 2

Pain Management

• Severe visceral and neuropathic pain dominates end-stage disease and requires aggressive opioid therapy with morphine, fentanyl, or tramadol titrated every 4 hours with hourly rescue doses for breakthrough pain. 1
• For neuropathic pain from celiac plexus involvement, add adjuvant medications: gabapentin, pregabalin, nortriptyline, or duloxetine. 1, 2
• Celiac plexus neurolysis should be pursued urgently if the patient is stable enough for the procedure, achieving pain relief in 50-90% of patients with effects lasting 1 month to 1 year. 4, 1, 2
• Palliative radiotherapy may augment pain management in refractory cases. 4, 1
• Prescribe scheduled laxatives for opioid-induced constipation and metoclopramide for nausea. 2

Biliary Obstruction Management

• Endoscopic placement of self-expanding metal stents is the preferred intervention to relieve jaundice, intractable pruritus, and prevent cholangitis. 4, 1
• Metal stents are superior to plastic stents, which should only be reserved for patients with expected survival <3 months. 1
• When endoscopic access is not possible, percutaneous transhepatic biliary drainage is advised. 1
• Jaundice occurs in 70-80% of patients with pancreatic head tumors and is commonly accompanied by pruritus, dark urine, and risk of ascending cholangitis. 1

Gastric Outlet Obstruction Management

• Endoscopic duodenal stenting with expandable metal stents is the primary palliative option when gastric outlet obstruction occurs, achieving relief in the majority with median stent patency of 6 months. 4, 1
• Metoclopramide and other prokinetic agents can facilitate gastric emptying. 1
• Neither chemotherapy nor radiotherapy provides effective palliation for gastric outlet obstruction. 1

Malignant Ascites Management

• Intermittent paracentesis provides relief lasting approximately 3 days when ascites causes abdominal distension, nausea, vomiting, and dyspnea from diaphragmatic pressure. 1
• Spironolactone reduces reaccumulation by antagonizing aldosterone-mediated sodium retention. 1
• Permanent drainage catheters are indicated when paracentesis is needed more than weekly. 1

Nutritional Support

• Pancreatic enzyme replacement (pancrelipase with meals) should be prescribed to address exocrine pancreatic insufficiency, with studies showing 1.2% weight gain versus 3.7% loss without replacement. 1
• Progressive cachexia with profound functional decline is universal and driven by tumor-induced metabolic derangements that are largely irreversible. 1, 2

Psychosocial Support

• Depression and anxiety are nearly universal given the aggressive nature and poor prognosis of metastatic disease. 1
• All patients require assessment of psychological status and social supports, with antidepressants, anxiolytics, and referral to social work or psychiatry initiated early. 1
• Nearly 90% of adults desire palliative care services when informed of their availability. 1

Communication and Goals of Care

• Clear communication with patients and caregivers about the diagnosis, prognosis, and goals of care is essential for patient understanding. 4
• Providers should ask patients about their personal goals and preferences: What do they hope for? What is important to them? What do they value more—extension of life or maintenance of quality of life? 4
• An understanding of a patient's specific goals should shape conversations about goals of care and treatment recommendations. 4

Critical Pitfalls to Avoid

• Do not delay hospice conversation until the patient has zero treatment options—hospice discussion should begin when disease is progressing and performance status is declining. 3
• Do not undertreat pain due to opioid hesitancy—aggressive titration with rescue dosing is essential for adequate symptom control. 1, 2
• Do not fail to address biliary or gastric outlet obstruction with endoscopic stenting, which significantly improves comfort and quality of life. 4, 1
• Do not overlook venous thromboembolism risk—pancreatic cancer has one of the highest rates of VTE among all malignancies, and VTE is the second leading cause of death after the cancer itself. 1
