Lymphoma group R-CODOX-M / R-IVAC INDICATION Burkitt lymphoma, ‘double hit’ lymphoma or high IPI diffuse large B-cell lymphoma. TREATMENT INTENT Curative. PRE-ASSESSMENT 1. Ensure histology is confirmed prior to administration of chemotherapy and document in notes. 2. Record stage of disease - MRI scan of brain (+/- spinal cord) with Gadolinium enhancement, CT scan (neck, chest, abdomen and pelvis) +/- PET, presence or absence of B symptoms, clinical extent of disease, consider bone marrow aspirate and trephine (with cytogenetics/FISH as indicated). 3. Blood tests - FBC, DAT, U&Es, LDH, ESR, urate, calcium, magnesium, creatinine, LFTs, glucose, Igs, β2 microglobulin, hepatitis B core antibody and hepatitis BsAg, hepatitis C antibody, EBV, CMV, VZV, HIV 1+2 after consent, group and save. 4. A number of drugs can interfere with tubular secretion of methotrexate. These include penicillins, aspirin and NSAIDs. Tazocin should NOT be used during high dose methotrexate administration or rescue. Consider using meropenem or other alternative. Review indications for aspirin and NSAIDs and consider stopping during methotrexate treatment. 5. Patients MUST NOT receive co-trimoxazole, starting from the week before the first methotrexate infusion. Consider pentamidine treatment if considered at risk from Pneumocystis infection. 6. CSF examination • cell count +/- immunophenotype, protein and glucose: can be done as part of 1st intrathecal. 7. Ophthalmic examination - if clinically indicated. 8. Urine pregnancy test • before cycle 1 of each new chemotherapy for women of child-bearing age unless they are post-menopausal, have been sterilised or undergone a hysterectomy. 9. ECG +/- Echo - if clinically indicated. 10. Record performance status (WHO/ECOG), height and weight. 11. Consent - ensure patient has received adequate verbal and written information regarding their disease, treatment and potential side effects. Document in medical notes all information that has been given. Obtain written consent on the day of treatment. 12. Fertility - it is very important the patient understands the potential risk of infertility. All patients should be offered fertility advice by referring to the Oxford Fertility Unit. 13. Hydration - in patients with bulky disease pre-hydrate with sodium chloride 0.9% 1 litre over 4- 6 hours. Patients at high risk of tumour lysis refer to tumour lysis protocol. 14. Consider dental assessment / Advise dental check is carried out by patient's own dental practitioner before treatment starts. 15. Record IPI score. 16. Arrange insertion of double-lumen central venous catheter. 17. Treatment should be agreed in the relevant MDT.

For high-risk patients, give alternate CODOX-M and IVAC for four cycles. Risk groups can be identified as follows: Patients in the low-risk group must meet at least 3 of the following criteria: o Normal lactate dehydrogenase (LDH) level o WHO performance status 0-1 o Ann Arbor stage I or II o No more than 1 extranodal site (e.g., bone marrow, gastrointestinal tract, or CNS) Patients in the high-risk group must meet at least 2 of the following criteria: o Raised LDH level o WHO performance status 2-4 o Ann Arbor stage III or IV o More than 1 extranodal site See dose modification for patients over 65 years.
