Steroid Toxicity, Opioid Fears, and a Child's Own Voice
Toby is a 9-year-old boy with diffuse intrinsic pontine glioma, 11 months from diagnosis, after radiation. He now has progressive dysphagia, choking on liquids, morning headaches, and a left-sided weakness. He has taken dexamethasone 8 mg daily for three months and is cushingoid, with proximal weakness, insomnia, irritability, and a 6 kg weight gain. He rates his headache 8/10 and says, 'I hate the hospital. I want to be home.' His parents refuse morphine because 'it's addictive and it will stop his breathing,' and they want 'everything done.' He weighs 25 kg and can no longer reliably swallow tablets.
1. How do you weigh continuing, tapering, or increasing dexamethasone, and what alternatives address his headache?

Dexamethasone has probably contributed to his headache relief by reducing peritumoral edema, but three months at 8 mg daily has produced substantial toxicity: cushingoid habitus, proximal myopathy, insomnia, irritability, and weight gain. The goal is the lowest dose that preserves function and comfort, not the highest dose tolerated.
Reasonable approach: taper gradually - for example, to 4 mg daily for 1–2 weeks, then 2 mg daily, while monitoring headache, vomiting, and level of alertness. Do not stop abruptly. If headache worsens significantly, return to the last effective dose rather than escalating indefinitely; document that the purpose is comfort, not tumor control. Add scheduled acetaminophen and an opioid for breakthrough headache. Consider that dysphagia and aspiration may be worsened by sedation and that steroids do not prevent aspiration.
Discuss with the family that steroids are a comfort tool with real harms, and that 'everything' can include reducing a medicine that is making him miserable. Reassess in one week, ideally at home.
2. How would you counsel the parents about morphine and start it safely, given that he cannot swallow tablets?

Address the myths directly and with respect. Explain that morphine is the standard treatment for severe cancer headache and dyspnea; when titrated to pain, it rarely causes clinically significant respiratory depression because pain is a respiratory stimulus. Addiction in a child with no substance-use history and no prior exposure is exceedingly rare; the real risks are constipation, sedation, and nausea, which are managed proactively. Untreated pain is itself harmful. Say plainly: 'This is not the same as street heroin, and giving it for pain does not shorten his life.'
Because he cannot swallow, use the subcutaneous or intravenous route: morphine 0.05–0.1 mg/kg (1.25–2.5 mg) every 2–4 hours as needed, or an equivalent low-dose infusion once the 24-hour requirement is known. Alternatively, oral morphine solution 0.15–0.3 mg/kg (3.75–7.5 mg) every 4 hours if swallowing is safe. Prescribe senna or polyethylene glycol, an antiemetic, and a written breakthrough plan. Set expectations: the goal is a comfortable, awake child at home, not sedation.
3. His parents want 'everything done' and hospital care, while Toby says he wants to go home. How do you proceed?

Do not frame this as the child versus the parents. Toby's statement is developmentally meaningful: at 9, children understand finality and can participate in decisions, although they generally lack legal authority to refuse life-sustaining treatment. His assent should shape care, and his parents remain the decision-makers.
Explore what 'everything' means to them - often it means 'do not abandon us' rather than a specific intervention. Explain that home hospice is not giving up; it is intensive care delivered where he wants to be. Ask Toby what he understands and what he wants to know, using simple, honest language, and offer to speak with him alone if he wishes. Involve child life, social work, and the school. Address the parents' fear that stopping hospital care means stopping treatment; distinguish hospice from no care.
Aim for a negotiated plan: home with hospice, 24-hour support, and a clear readmission plan if symptoms escalate. Document the goals, Toby's stated wishes, and the parents' concerns, and revisit at each visit.
