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.
