3 Policy for CNS Prophylaxis in Lymphoid Malignancies Background CNS relapse is rare in most tumour types but conveys very poor prognosis when it occurs. The risk of CNS relapse is dependent on a number of factors including histological subtype, site of primary disease and other factors eg LDH. Some patients will have CNS disease at diagnosis, which is outside the scope of this document. CNS disease usually occurs early with a median of 5-12 months from diagnosis with ~33% of cases occurring during primary therapy [1-3]. Disease can be either parenchymal or leptomeningeal, therefore prophylaxis must adequately treat both. Recent BCSH guidelines recommend intrathecal therapy (IT) but acknowledge the weaknesses in the evidence for IT prophylaxis.[3] Systemic therapy with high dose methotrexate (MTX) is suggested as a possible alternative. Risk Stratification Burkitt s Lymphoma, Lymphoblastic Lymphoma & ATLL All cases high risk (>20%) CNS prophylaxis incorporated in standard treatment schedules Diffuse Large B Cell Lymphoma overall risk 5% [4, 5] High Risk Subgroups Disease sites testes [6, 7], breast [8], paraspinal masses, intravascular lymphoma [9], epidural space [10], paranasal sinuses MYC +ve (MYC translocation demonstrable by FISH) [11] High LDH and >1 extranodal sites [12, 13] Isolated renal and marrow involvement are rare and the reported high incidence of CNS relapse is confounded by other better established high risk features (eg high LDH, multiple extranodal sites) [3, 14] Mantle Cell Lymphoma 4-9% [15] CNS relapse usually seen with systemic relapse Insufficient evidence for routine prophylaxis Intensive treatment includes high dose Cytarabine which will penetrate CNS Peripheral T Cell Lymphoma- <4% [16] No published studies specifically address risk of CNS relapse in PTCL Retrospective analyses found no cases in patients with Angioimmunoblastic T cell Lymphoma, Hepatosplenic T cell Lymphoma or Enteropathy associated T cell Lymphoma Suggested for PTCL, NOS with risk factors cf DLBCL Anaplastic NHL 1-3% Insufficient data for primary prophylaxis Follicular Lymphoma - <1% CNS relapse mainly seen with high grade transformation NOSCAN Policy for CNS Prophylaxis in Lymphoid Malignancies V2.0 [April 2016] Page 3 of 7

4 No rationale for routine prophylaxis Small lymphocytic lymphoma - <1% MALT lymphoma - <1% Hodgkin s lymphoma - <0.5% No rationale for routine prophylaxis HIV related lymphoma Increase in Primary CNS Lymphoma and CNS involvement in systemic NHL (17-23%) CNS prophylaxis recommended for all patients [17] Due to concerns about toxicity and interactions with HAART IT MTX is preferred over IV MTX for this specific situation Indications for CNS prophylaxis In view of the above the following should ALWAYS receive CNS prophylaxis unless they are too unfit: Burkitt s lymphoma Lymphoblastic lymphoma ATLL DLBCL & PTCL (NOS) if: 1. High LDH with >1 extranodal site 2. Involvement of testes, breast, epidural space, paraspinal mass, paranasal sinuses or intravascular lymphoma 3. MYC +ve 4. HIV +ve Patients not falling into the above categories should be considered on an individual basis at the local MDT. CNS prophylaxis regimen CNS prophylaxis is included in standard protocols for Burkitt s lymphoma, Lymphoblastic lymphoma and ATLL DLBCL or PTCL (NOS): IT MTX has been most commonly used historically however 2 large randomised controlled trials have failed to show any protective benefit [1, 2]. Additionally, a recent study in patients treated with chemoimmunotherapy also failed to demonstrate benefit of IT MTX [18]. Furthermore, studies that have demonstrated a benefit of CNS prophylaxis have combined IT MTX with High Dose MTX [13, 19]. A retrospective study of DLBCL has shown that High Dose MTX can be safely delivered with R-CHOP and is associated with a low risk (2 out of 65 high risk patients) of CNS relapse [20].

5 Recommendation (Also see page 7) Published evidence suggests that lower doses will be ineffective [1, 12, 21, 22]. If 3g/m 2 cannot be safely delivered due to liver or renal impairment or concerns about tolerability due to comorbidity/frailty then prophylaxis with IT MTX 12.5mg for 3 doses with cycles 2-4 of R-CHOP may be considered in line with current BCSH Guidelines [3].
