Supportive Care Factors

Factor Value
Antiviral prophylaxis for herpes virus: Routine antiviral prophylaxis may be considered
Emetogenicity: Variable
Gastroprotection: Gastroprotection may be considered
Growth factor support: Recommended for primary prophylaxis
Irradiated blood components: Variable
Ocular toxicity risk: High - administer corticosteroid eyedrops to minimise corneal toxicity
Pneumocystis jirovecii pneumonia (PJP) prophylaxis: Routine antibiotic prophylaxis recommended
Tumour lysis syndrome prophylaxis: Tumour lysis syndrome prophylaxis is recommended

Antiviral prophylaxis for hepatitis B virus: Guidance is limited to high-risk anti-cancer medicines. Clinicians will need to assess individual patient risk for other anti-cancer medicines.

Emetogenicity: HIGH (cARBOplatin) day 1; MEDIUM day 2.

Irradiated blood components: Required for Hodgkin lymphoma patients at all stages of disease and therapy. Continue indefinitely.

Tumour lysis syndrome prophylaxis: Recommended for cycle 1 and consider for subsequent cycles.
