📋 Key Information Summary
- Early integration of palliative care alongside active oncology treatment improves symptom burden, quality of life, prognostic understanding, and in some tumour types overall survival (Temel et al., NEJM 2010).
- Palliative care referral should occur within 8 weeks of diagnosis for advanced cancer, at any stage when symptom burden is high, or when goals-of-care discussions are needed — not reserved for the terminal phase.
- Cancer pain is best managed with the WHO analgesic ladder; strong opioids (oxycodone, morphine, fentanyl, methadone) are the mainstay for moderate-to-severe cancer pain and are PBS-listed under Authority Required for cancer indications.
- Opioid side-effect prophylaxis with aperients (docusate + senna or macrogol) is mandatory; anti-emetics (metoclopramide, haloperidol) for nausea should be co-prescribed in opioid initiation.
- Malignant spinal cord compression (MSCC) is an oncological emergency — dexamethasone 16 mg IV immediately, urgent MRI whole spine within 24 hours, and referral for radiotherapy or surgery.
- Superior vena cava (SVC) obstruction warrants urgent CT with contrast and oncology referral; stenting or radiotherapy provides rapid symptom relief.
- Malignant hypercalcaemia (corrected calcium >3.0 mmol/L) is managed with IV normal saline 0.9% 3–4 L over 24 hours then IV zoledronic acid 4 mg or denosumab 120 mg SC if zoledronic acid contraindicated.
- Neutropenic sepsis in febrile oncology patients (ANC <0.5 × 10⁹/L, temp ≥38.0°C) requires immediate IV broad-spectrum antibiotics — piperacillin–tazobactam 4.5 g IV or meropenem 1 g IV — within 60 minutes of arrival.
- Paraneoplastic syndromes (SIADH, Cushing syndrome, Lambert–Eaton myasthenic syndrome, cerebellar degeneration) may precede cancer diagnosis and require both immunotherapy/tumour-directed treatment and specialist palliative symptom management.
- Cancer-related anorexia–cachexia syndrome (CACS) responds best to early dietitian input, olanzapine 2.5–5 mg nocte (off-label), corticosteroids short-term (dexamethasone 4 mg mane), and megestrol acetate where appropriate.
- Dyspnoea in advanced cancer is managed with low-dose immediate-release morphine 2.5–5 mg PO/SC PRN (opioid-naïve), fan therapy, and treatment of reversible causes (pleural effusion, bronchospasm, PE).
- Aboriginal and Torres Strait Islander communities experience higher cancer mortality, later-stage diagnosis, and barriers to palliative care access; culturally safe, community-based models and advance care planning in language are essential.
- Delirium in advanced cancer is common (25–85% at end of life); identify and treat reversible causes (medications, infection, constipation, urinary retention), use haloperidol 0.5–1 mg SC/PO or risperidone/midazolam for refractory agitation.
Introduction & Australian Epidemiology
Palliative care in cancer encompasses the early integration of symptom management, psychosocial support, communication around prognosis and goals of care, and end-of-life planning alongside active disease-modifying oncology treatment. It is not synonymous with end-of-life care. Australian and international evidence demonstrates that early palliative care referral improves quality of life, reduces emergency department presentations and hospital deaths, enhances patient satisfaction, and — in certain cancers such as non-small-cell lung cancer — may improve overall survival.
In Australia, cancer is the leading cause of disease burden, accounting for approximately 150,000 new diagnoses and over 50,000 deaths annually (Australian Institute of Health and Welfare [AIHW], 2023). Lung, colorectal, breast, prostate, and melanoma are the most common cancers. Despite improvements in five-year survival (now ~70% overall), many patients present with advanced or metastatic disease, and an estimated 70–80% of people dying of cancer would benefit from palliative care input at some stage.
Palliative Medicine is a recognised specialty in Australia through the Australasian Chapter of Palliative Medicine (AChPM) under the Royal Australasian College of Physicians (RACP). Palliative care services operate across hospital, community, hospice, and telehealth settings, though access remains inequitable — particularly in rural and remote areas and for Aboriginal and Torres Strait Islander peoples.
Early Integration of Palliative Care
Rationale for Early Referral
The landmark Temel et al. (2010) randomised controlled trial in metastatic non-small-cell lung cancer demonstrated that early palliative care (within 8 weeks of diagnosis) improved quality of life, reduced depressive symptoms, and — unexpectedly — improved median survival by 2.7 months. Subsequent meta-analyses (Haun et al., 2017; Fulton et al., 2019) confirmed benefits across multiple tumour types: improved symptom control, reduced hospital admissions, fewer intensive chemotherapy regimens in the last 30 days of life, and better caregiver outcomes.
When to Refer
Indications for palliative care referral in cancer include:
- Diagnosis of advanced or metastatic solid-organ cancer (ideally within 8 weeks)
- Haematological malignancy with poor prognosis or high symptom burden (leukaemia, relapsed lymphoma, myeloma with refractory disease)
- Recurrent or treatment-refractory cancer regardless of histology
- Uncontrolled symptoms: pain, nausea, dyspnoea, delirium, anorexia–cachexia
- Oncological emergencies (spinal cord compression, SVC obstruction, hypercalcaemia)
- Need for goals-of-care discussion or advance care planning
- Caregiver distress or complex psychosocial needs
- Patient or family request for palliative care involvement
Models of Integrated Care in Australia
Australian cancer services increasingly embed palliative care within multidisciplinary teams (MDTs). Models include:
- Embedded palliative care in oncology clinics: Shared outpatient appointments with oncologist and palliative care physician (implemented at Peter MacCallum Cancer Centre, Chris O'Brien Lifehouse, Royal Brisbane).
- Trigger-based automatic referral: Electronic health record triggers for referral when patients meet defined criteria (e.g., stage IV diagnosis, hospital admission for symptom crisis).
- Telehealth palliative care: Specialist palliative care via telehealth for rural/remote patients through services such as Palliative Care NSW, QPall, and the Australian Government's telehealth MBS items (99441–99443 for specialist video consultations).
- Community palliative care: State-funded community palliative care services provide home visiting, after-hours telephone support, and care coordination. In most states, these services are free of charge.
Goals-of-Care Conversations
Effective communication about prognosis, treatment intent, and end-of-life preferences is a core palliative care competency. Australian frameworks include:
- Ask-Tell-Ask and SPIKES communication models for breaking bad news
- Respecting Patient Choices (Victoria) and Statement of Choices for advance care planning documentation
- Goals of Patient Care (GoPC) form — a nationally consistent clinical document (ACSQHC) replacing resuscitation plans in many jurisdictions
- Substitute Decision-Maker (SDM) legislation varies by state/territory; clinicians should document the patient's SDM early

Cancer Symptom Management
Up to 80% of patients with advanced cancer experience significant symptom burden. Systematic assessment using validated tools (e.g., Edmonton Symptom Assessment System [ESAS], Integrated Palliative Care Outcome Scale [IPOS]) and proactive management are essential. The following addresses the most common cancer-related symptoms.
Cancer Pain
Cancer pain affects 50–70% of patients during treatment and up to 90% with advanced disease. It may be nociceptive (somatic or visceral), neuropathic, or mixed. The WHO three-step analgesic ladder remains the foundational framework, though in practice, moderate-to-severe cancer pain often requires initiation of strong opioids directly.
WHO Analgesic Ladder — Application in Cancer Pain
Strong Opioids for Cancer Pain
Adjuvant Analgesics for Cancer Pain
| Indication | Adjuvant Agent | Dose | Notes |
|---|---|---|---|
| Neuropathic pain (bone metastases, nerve infiltration) | Gabapentin | Start 100–300 mg nocte, titrate to 300–600 mg TDS | PBS Authority Required. Renal adjustment required. |
| Neuropathic pain | Pregabalin | Start 25–75 mg BD, titrate to 150–300 mg BD | PBS Authority Required. Renal adjustment required. |
| Bone metastases pain | Dexamethasone | 4–8 mg PO mane | Short course; taper when possible. Reduces peri-tumour oedema. |
| Bone metastases | Zoledronic acid | 4 mg IV over 15 min every 4 weeks | PBS-listed for bone metastases. Dental review before initiation. |
| Bone metastases | Denosumab | 120 mg SC every 4 weeks | PBS Authority Required. Monitor calcium. Risk of osteonecrosis jaw. |
| Visceral pain / bowel colic | Hyoscine butylbromide | 20 mg SC/PO every 4–6 hours | Reduces smooth muscle spasm. Anticholinergic side effects. |
| Muscle spasm | Diazepam / Baclofen | Diazepam 2–5 mg PO BD–TDS; Baclofen 5–10 mg TDS | Caution in elderly, hepatic impairment. |
| Bony pain (radiotherapy referral) | Palliative radiotherapy | Single fraction 8 Gy or 30 Gy/10# | Effective for localised bone metastases pain. MBS item 15200. |
Opioid Side-Effect Management
Nausea and Vomiting
Nausea in cancer is multifactorial: chemotherapy-induced (CINV), opioid-related, constipation, gastric stasis, raised intracranial pressure, metabolic (hypercalcaemia, uraemia), or anxiety-related. Identifying the cause guides anti-emetic selection.
| Mechanism | First-Line Agent | Dose |
|---|---|---|
| Gastric stasis / opioid-induced | Metoclopramide | 10 mg PO/SC TDS (prokinetic — avoid in bowel obstruction) |
| Chemotherapy-induced (acute CINV) | Ondansetron ± dexamethasone ± aprepitant | Ondansetron 8 mg IV/PO; Dexamethasone 8–12 mg IV; Aprepitant 125 mg PO D1, 80 mg D2–3 |
| Raised ICP / vestibular | Dexamethasone ± cyclizine | Dexamethasone 8–16 mg IV/PO daily; Cyclizine 50 mg PO/SC/IV TDS |
| Metabolic (hypercalcaemia, renal failure) | Haloperidol | 0.5–2 mg PO/SC/IV TDS |
| Bowel obstruction (partial/inoperable) | Cyclizine + octreotide ± dexamethasone | Cyclizine 50 mg SC TDS; Octreotide 100–300 mcg SC TDS (reduces secretion) |
| Anxiety-related / anticipatory | Lorazepam / midazolam | Lorazepam 0.5–1 mg SL PRN; Midazolam 2.5 mg SC PRN (palliative care only) |
| Refractory nausea | Levomepromazine (methotrimeprazine) | 3–6 mg SC/PO daily (specialist palliative care; sedating) |
Anorexia–Cachexia Syndrome (CACS)
Cancer anorexia–cachexia syndrome is characterised by ongoing loss of skeletal muscle mass (with or without fat loss) that cannot be fully reversed by conventional nutritional support. It affects 50–80% of advanced cancer patients and is an independent predictor of mortality. Management requires a multimodal approach.
Cancer-Related Fatigue (CRF)
Cancer-related fatigue is the most prevalent cancer symptom (60–100% of patients) and persists long after treatment in up to 30% of survivors. It is multidimensional — physical, emotional, and cognitive. Assessment should exclude reversible causes: anaemia, thyroid dysfunction, depression, sleep disturbance, medication effects (opioids, beta-blockers), and deconditioning.
- Exercise: Strongest evidence base — moderate aerobic exercise (150 min/week) and resistance training reduce CRF during and after treatment. Refer to exercise physiologist (MBS item 10952–10954 via GP Management Plan).
- Treat underlying causes: Correct anaemia (transfusion or ESAs if chemotherapy-related), manage depression (SSRI/SNRI), optimise thyroid function.
- Psychoeducation and CBT: Cognitive behavioural therapy has moderate evidence for CRF.
- Pharmacological options (limited evidence): Dexamethasone 4 mg PO BD (short-term benefit), methylphenidate 5–10 mg PO mane (specialist use; limited PBS access for this indication).
Dyspnoea
Dyspnoea in advanced cancer is multifactorial: lung parenchymal disease, pleural effusion, airway obstruction, lymphangitis carcinomatosa, pulmonary embolism, pericardial effusion, anaemia, deconditioning, and anxiety. Management focuses on treating reversible causes and symptom relief when the cause is irreversible.
- Low-dose opioids: The most evidence-based pharmacological intervention for refractory dyspnoea. Start immediate-release morphine 2.5–5 mg PO/SC every 4 hours PRN (opioid-naïve). Titrate by 30% of the total daily dose every 24–48 hours.
- Supplemental oxygen: Only beneficial if hypoxaemic (SpO₂ <90%). In normoxaemic dyspnoea, a fan directed at the face is equally effective and avoids equipment burden.
- Reversible causes: Drain pleural effusion (therapeutic aspiration or IPC insertion), treat bronchospasm (salbutamol nebuliser), anticoagulate for PE, drain pericardial effusion.
- Non-pharmacological: Positioning (upright, leaning forward), breathing exercises, relaxation therapy, psychosocial support, and advance care planning regarding ventilation preferences.
Constipation
Constipation affects up to 50% of cancer patients due to opioids, reduced mobility, dehydration, autonomic dysfunction, and anticholinergic medications. It is almost entirely preventable with proactive aperient co-prescription.
- Prevention: Co-prescribe stimulant + softener — docusate 100 mg + senna 8–16 mg PO nocte, or macrogol 3350 (Movicol®) 1–2 sachets daily.
- Escalation: If no bowel movement for 3 days: add bisacodyl 10 mg PR, sodium picosulfate 5–10 mL PO, or lactulose 15–30 mL BD.
- Faecal impaction: Glycerol suppository or phosphate enema. Manual evacuation only if medical management fails.
- Intestinal obstruction: See Cancer Complications section below.
Delirium
Delirium occurs in 25–85% of patients with advanced cancer in the terminal phase. It may be hyperactive (agitation, hallucinations), hypoactive (withdrawal, reduced consciousness — often under-recognised), or mixed.
Reversible causes to identify and treat:
- Medications (opioids, anticholinergics, benzodiazepines, corticosteroids, anti-emetics)
- Infection (UTI, pneumonia — particularly in neutropenic patients)
- Constipation / urinary retention
- Metabolic (hypercalcaemia, hyponatraemia, hepatic/renal failure)
- Hypoxia, dehydration, sleep deprivation
Cancer Complications — Oncological Emergencies
Several cancer-related complications constitute oncological emergencies requiring rapid assessment and intervention. Palliative care involvement should be concurrent with emergency management, focusing on symptom relief, communication, and alignment of treatment with goals of care.
Malignant Spinal Cord Compression (MSCC)
Epidemiology: Occurs in 5–10% of cancer patients. Most common primary tumours: breast, lung, prostate, renal cell carcinoma, myeloma. Thoracic spine (70%) > lumbar (20%) > cervical (10%).
Red flags requiring emergency investigation:
- New or progressive back pain in a patient with known malignancy
- Bilateral leg weakness or sensory changes
- New urinary retention or incontinence, faecal incontinence
- Sensory level on examination
- Lhermitte sign or band-like thoracic pain
Immediate Management
Superior Vena Cava (SVC) Obstruction
Epidemiology: Most commonly caused by lung cancer (especially small-cell and squamous cell), lymphoma, or mediastinal metastases. SVC syndrome may also arise from indwelling central venous devices.
Clinical features: Facial/neck/arm swelling (worse on waking), plethora, prominent chest wall venous collaterals, dyspnoea, cough, hoarseness (recurrent laryngeal nerve), headache, visual disturbance. Stridor indicates airway compromise — an emergency.
Management:
- CT chest with contrast (diagnostic and assesses extent of obstruction)
- Elevate head of bed; supplemental oxygen if hypoxaemic
- Dexamethasone 8–16 mg IV/PO daily (reduces peri-tumour oedema — most useful in lymphoma)
- Definitive treatment depends on histology: Chemotherapy (small-cell lung cancer, lymphoma), radiotherapy (NSCLC), endovascular stenting (rapid decompression, 90% patency)
- If no treatment possible: palliative stenting for symptom relief; goals-of-care discussion
Malignant Hypercalcaemia
Epidemiology: Occurs in 10–30% of advanced cancers. Mechanism: PTHrP secretion (squamous cell carcinoma, breast, renal, bladder), osteolytic metastases (breast, myeloma), or ectopic PTH production (rare). It indicates advanced disease and poor prognosis (median survival ~3 months without effective cancer treatment).
Symptoms (often remembered as "Bones, stones, groans, and psychic moans"):
- Constitutional: fatigue, dehydration, weight loss
- Neuropsychiatric: confusion, delirium, depression, psychosis, coma
- Gastrointestinal: nausea, vomiting, constipation, anorexia, pancreatitis
- Renal: polyuria, polydipsia, nephrogenic DI, acute kidney injury
- Cardiac: shortened QTc, arrhythmias, bradycardia (risk of cardiac arrest if Ca²⁺ >3.5 mmol/L)
Severity and Management
Neutropenic Sepsis
Definition: Fever ≥38.0°C (single reading) or ≥37.5°C sustained over 1 hour, with absolute neutrophil count (ANC) <0.5 × 10⁹/L (or <1.0 × 10⁹/L with expected decline) in a patient receiving or within 14 days of chemotherapy.
Empirical Antibiotic Therapy
Additional management:
- Blood cultures (peripheral + central line if in situ) × 2 sets before antibiotics
- FBC, CRP, lactate, renal function, LFTs, coagulation
- Chest X-ray; urine culture; assess for line infection
- Consider adding vancomycin 25–30 mg/kg IV if: suspected line infection, skin/soft tissue focus, severe sepsis, or local MRSA prevalence high
- Add antifungal (caspofungin 70 mg IV day 1 then 50 mg daily) if fever persists >96 hours despite broad-spectrum antibiotics (fungal infection likely)
- G-CSF (filgrastim or pegfilgrastim) may be considered per eTG/local protocols to shorten neutropenia duration
Malignant Bowel Obstruction (MBO)
MBO is common in advanced ovarian, colorectal, and gastric cancers, and peritoneal carcinomatosis. Management depends on whether surgical intervention is feasible and aligned with goals of care.
Conservative (Medical) Management for Inoperable MBO
- Nasogastric tube (NGT): Intermittent aspiration for gastric decompression (not long-term; aim for removal when possible)
- IV fluids: Restrict to 1–1.5 L/day 0.9% saline if not tolerating oral; avoid overhydration (contributes to secretion volume)
- Anti-secretory agents: Octreotide 100–300 mcg SC TDS (reduces gastrointestinal secretions) — most effective agent for MBO symptoms
- Anti-emetics: Cyclizine 50 mg SC/IV TDS (anti-emetic, anti-secretory); or haloperidol 0.5–1 mg SC TDS. Avoid metoclopramide (prokinetic — contraindicated in complete obstruction)
- Corticosteroids: Dexamethasone 8–16 mg IV daily (reduces peri-tumour oedema, may resolve partial obstruction)
- Analgesia: Opioid via SC route (fentanyl or hydromorphone preferred in renal impairment; morphine acceptable if renal function normal). Use syringe driver (CADD-MS 3 or similar) for continuous SC infusion.
Leptomeningeal Disease (Carcinomatous Meningitis)
Leptomeningeal metastases occur in 3–8% of solid tumour cancers (breast, lung, melanoma) and up to 20% of haematological malignancies. Presentation includes cranial nerve palsies, multifocal neurological deficits, radiculopathy, raised intracranial pressure (headache, nausea, papilloedema), and cognitive changes.
Diagnosis: Gadolinium-enhanced MRI brain and whole spine (sensitivity ~70%). CSF analysis (low glucose, high protein, positive cytology — sensitivity improves with ≥10 mL volume, first sample, and repeat if initial negative). CSF should be collected from lumbar puncture (not ventricular).
Prognosis: Poor — median survival 4–6 weeks without treatment, 2–3 months with intrathecal chemotherapy or craniospinal radiotherapy (selected patients). Goals-of-care discussion is essential.
Symptomatic management: Dexamethasone 8–16 mg daily (reduces cerebral oedema); analgesia for headache; anti-emetics; supportive care with palliative care team involvement.
Paraneoplastic Syndromes
Paraneoplastic syndromes are clinical manifestations caused by the remote effects of malignancy — mediated by hormonal, immunological, or other mechanisms — rather than by direct tumour invasion, metastasis, or treatment toxicity. They may precede the cancer diagnosis by months to years, occur concurrently, or develop during the disease course. Recognition is critical, as the underlying malignancy may be treatable even when the paraneoplastic syndrome itself is difficult to reverse.
Overview of Paraneoplastic Syndromes
| Syndrome | Mechanism | Associated Cancers | Key Features |
|---|---|---|---|
| SIADH (Syndrome of Inappropriate ADH) | Ectopic ADH/vasopressin production | Small-cell lung cancer (most common), CNS tumours, head & neck SCC | Hyponatraemia (Na⁺ <135 mmol/L), euvolaemic, concentrated urine, seizures if severe |
| Ectopic ACTH / Cushing syndrome | Ectopic ACTH production | Small-cell lung cancer, bronchial carcinoid, medullary thyroid, phaeochromocytoma | Rapid-onset: proximal myopathy, hypokalaemia, metabolic alkalosis, hyperglycaemia, hypertension, skin pigmentation. Often severe — cortisol level much higher than pituitary Cushing's. |
| Hypercalcaemia of malignancy (see above) | PTHrP secretion, osteolysis | Squamous cell (lung, head & neck), breast, renal, bladder, myeloma | Classified as a paraneoplastic syndrome when mediated by humoral factors (humoral hypercalcaemia of malignancy). |
| Lambert-Eaton Myasthenic Syndrome (LEMS) | Anti-VGCC antibodies (autoimmune) | Small-cell lung cancer (60% of LEMS cases are paraneoplastic) | Proximal weakness (legs > arms), reduced reflexes, autonomic dysfunction (dry mouth, constipation), facilitation phenomenon on EMG (incremental response with repeated stimulation) |
| Paraneoplastic cerebellar degeneration | Anti-Yo (breast/ovary), Anti-Hu (SCLC), Anti-Tr (Hodgkin) | Breast, ovarian, SCLC, Hodgkin lymphoma | Subacute progressive cerebellar ataxia, dysarthria, nystagmus, vertigo. Often severe and irreversible. MRI may show cerebellar atrophy. |
| Paraneoplastic encephalomyelitis / Anti-Hu syndrome | Anti-Hu (ANNA-1) antibodies | Small-cell lung cancer (>80%) | Limbic encephalitis, sensory neuronopathy, autonomic dysfunction, cerebellar ataxia. CSF shows pleocytosis and elevated protein. |
| Dermatomyositis | Autoimmune (anti-Mi-2, anti-NXP2, anti-TIF1γ) | Ovarian, lung, colorectal, breast, gastric, lymphoma | Proximal myopathy, heliotrope rash (periorbital), Gottron papules (dorsal hand joints), elevated CK. Cancer risk higher in adults >40 years with dermatomyositis (up to 25%). |
| Polymyositis / cancer-associated myositis | Autoimmune | Lung, breast, bladder, lymphoma, non-Hodgkin | Proximal muscle weakness without skin rash. CK elevated. Responds partially to corticosteroids. |
| Paraneoplastic pemphigus | Autoantibodies against desmoplakin, envoplakin | Non-Hodgkin lymphoma (especially CLL), Castleman disease, thymoma | Severe mucocutaneous blistering, painful oral erosions, bronchiolitis obliterans (poor prognosis) |
| Trousseau syndrome (migratory thrombophlebitis) | Hypercoagulable state, mucins activating coagulation | Pancreatic, gastric, lung, ovarian | Recurrent migratory superficial thrombophlebitis, DVT, PE, non-bacterial thrombotic endocarditis. Often unresponsive to warfarin — LMWH preferred. |
| Paraneoplastic glomerulonephritis | Immune complex deposition | Hodgkin lymphoma (minimal change), non-Hodgkin (membranous), CLL | Nephrotic syndrome, proteinuria. May remit with cancer treatment. |
Management Principles
- Treat the underlying cancer: The most effective treatment for a paraneoplastic syndrome is successful oncological treatment of the primary tumour. Some neurological syndromes may partially reverse with tumour response.
- Immunotherapy: For autoimmune-mediated paraneoplastic syndromes (LEMS, cerebellar degeneration, encephalomyelitis): IV immunoglobulin (IVIg) 0.4 g/kg/day × 5 days, plasmapheresis, corticosteroids (dexamethasone or methylprednisolone), and second-line agents (rituximab, cyclophosphamide) — managed by neurology/immunology.
- Specific syndrome management:
SIADH
- Fluid restriction (800–1000 mL/day) as first-line
- Demeclocycline 300 mg PO BD–TDS (induces nephrogenic DI; not PBS-listed in Australia, obtained through Special Access Scheme)
- Tolvaptan 15 mg PO daily, titrate to 60 mg (vasopressin V2 receptor antagonist) — PBS Authority Required, specialist-initiated
- For severe symptomatic hyponatraemia (Na⁺ <120 mmol/L, seizures): hypertonic saline 3% 150 mL IV over 20 minutes, with neurology/endocrine input. Correct sodium no faster than 8–10 mmol/L in 24 hours to avoid osmotic demyelination syndrome.
Ectopic ACTH Syndrome
- Ketoconazole 200–400 mg PO TDS (adrenal steroidogenesis inhibitor) — monitor LFTs
- Metyrapone 250–750 mg PO TDS (11β-hydroxylase inhibitor) — rapid onset
- Mifepristone (glucocorticoid receptor antagonist) — specialist use
- Treat hypokalaemia aggressively (KCl supplementation)
- Bilateral adrenalectomy if medical management fails and prognosis warrants
Lambert-Eaton Myasthenic Syndrome
- 3,4-Diaminopyridine (amifampridine) 10 mg PO TDS — improves neuromuscular transmission by blocking presynaptic K⁺ channels. Available through Special Access Scheme in Australia.
- IVIg or plasmapheresis for acute exacerbations
- Cancer treatment (tumour response often improves LEMS)
- Avoid aminoglycosides, magnesium, calcium channel blockers (worsen neuromuscular blockade)
Palliative Care Role in Paraneoplastic Syndromes
Palliative care involvement is essential in paraneoplastic syndromes that are:
- Irreversible or refractory to treatment (e.g., advanced cerebellar degeneration, severe encephalomyelitis)
- Causing significant symptom burden (pain, dysphagia, dyspnoea, immobility)
- Associated with advanced or untreatable malignancy
- Requiring complex symptom management alongside immunosuppressive therapy
- Creating significant psychosocial distress for patient and family
Rehabilitation (physiotherapy, occupational therapy, speech pathology) is critical for paraneoplastic neurological syndromes, particularly LEMS, cerebellar degeneration, and peripheral neuropathies.
Monitoring & Transition to End-of-Life Care
Ongoing Symptom Monitoring
Regular reassessment of symptom burden using validated tools is essential. The Edmonton Symptom Assessment System (ESAS-r) or Integrated Palliative Care Outcome Scale (IPOS) should be completed at every outpatient visit or weekly during inpatient care. Key monitoring parameters include:
- Pain (numerical rating scale 0–10), with reassessment after each dose adjustment
- Nausea, constipation, dyspnoea, drowsiness (opioid side effects)
- Functional status (Australian-modified Karnofsky Performance Status or Palliative Performance Scale [PPS])
- Psychological distress (Distress Thermometer; PHQ-2 for depression screening)
- Weight trajectory and nutritional intake
- Renal function (eGFR) when on renally cleared medications
- Calcium, sodium, and other metabolic parameters as clinically indicated
Recognising the Dying Phase
Recognising that a patient is in the last days of life is critical to providing good end-of-life care. The Supportive and Palliative Care Indicators Tool (SPICT) and clinical features of dying include:
- Bedbound, sleeping most of the time, only rousable to voice/touch
- Minimal oral intake — taking sips only, unable to swallow medications
- Semi-conscious or delirious (often terminal restlessness)
- Peripheral cyanosis, mottled skin, Cheyne–Stokes respiration
- Death rattle (pooled secretions — managed with glycopyrrolate 200 mcg SC or hyoscine butylbromide 20 mg SC)
Symptom Management in the Last Days of Life — Syringe Driver Regimen
When the oral route is lost, a subcutaneous continuous infusion (syringe driver) is the standard method of medication delivery. A commonly used approach:
| Symptom | Medication (24-hour SC infusion) | Typical Starting Dose |
|---|---|---|
| Pain | Morphine (SC dose = 50% of last oral 24-h dose) or fentanyl or hydromorphone | Morphine 10–30 mg/24h (opioid-experienced); or fentanyl 25–75 mcg/24h |
| Nausea / vomiting | Haloperidol or cyclizine or levomepromazine | Haloperidol 1–2.5 mg/24h or cyclizine 75–150 mg/24h |
| Agitation / restlessness | Midazolam | 10–30 mg/24h (escalate to 50–100 mg/24h for refractory terminal agitation) |
| Secretions (death rattle) | Hyoscine butylbromide or glycopyrrolate | Hyoscine butylbromide 60–80 mg/24h or glycopyrrolate 600–1200 mcg/24h |

Aboriginal and Torres Strait Islander Health Considerations
Aboriginal and Torres Strait Islander Australians experience significantly higher cancer mortality rates (1.4 times higher than non-Indigenous Australians), later-stage diagnosis, lower participation in cancer screening programmes, and poorer access to both oncology and palliative care services. Cultural safety, community engagement, and addressing systemic barriers are fundamental to equitable palliative care delivery.
