What to expect from chemotherapy for retinoblastoma

Retinoblastoma care is coordinated by a specialist team because the goal is to treat the tumour while protecting vision and supporting your child’s development. Medicines may be given through a vein, and some children need a small implanted access device for repeated treatment. The team may use chemotherapy before a local eye treatment, after another treatment, or when disease needs control beyond the eye. The exact medicines and schedule depend on the tumour’s features, whether one or both eyes are involved, and your child’s general health.

Before each visit, clinicians check blood counts and assess how your child is feeling. Common effects can include tiredness, reduced appetite, nausea, temporary hair loss and a lower ability to fight infection. Medicines for nausea and other symptoms can make treatment easier. Blood counts often recover between treatments, but the oncology team will explain what to expect for your child.

Keep a written treatment calendar and bring a list of medicines, allergies, temperatures and new symptoms to appointments. Offer small, familiar meals and regular drinks unless the team gives different instructions. Gentle activity and rest can both be useful. Follow the team’s guidance about hand washing, visitors and contact with anyone who is unwell. Ask how to care for the access device, what medicines to give at home, and which number to call day or night.

Contact the oncology team urgently if your child has a fever at the threshold they provided, chills, unusual sleepiness, breathing difficulty, repeated vomiting, cannot keep fluids down, or passes much less urine. Call promptly for bleeding, new severe pain, or redness, swelling or discharge around an access device. Do not give a fever-lowering medicine to hide a temperature unless the treatment team has advised it.

Ask which medicines your child will receive, how they will be given, how the plan supports vision, what monitoring is needed, and which symptoms require an immediate call. You can also ask about school or nursery attendance, infection precautions, fertility or long-term follow-up, and how the team will assess response.
