Demographics
3% of primary cerebral tumors
2-3% of all cases of NHL.
SEER data show incidence may be increasing among patients >65, with pts >75 having the highest incidental risk.
1900 new cases per year in U.S.
Limited prospective and/or randomized data to guide its therapy.
Historically associated with a poor prognosis.
Accumulation of recent prospective phase I/II results, and retrospective series demonstrate reproducible improvements in outcomes for patients with PCNSL and SCNSL.

Risk Factors
Acquired or congenital immunodeficiency states
(WAS, AT, SCID, CVID– 4% lifetime risk)
Renal transplant 1-2% lifetime risk
2-7% cardiac, lung, liver transplant– association
with T-cell specific immunodeficiency
(mycophenolate mofetil)
AIDS-defining illness, assoc. with very low CD4
count (<50cells/μL)—nearly 100% assoc w/EBV

What dose of MTX to use?
Optimal doses have not been defined
Doses > 1gm/m2 achieve tumoricidal levels of mtx in
brain parenchyma. (Skarin et al, BLOOD 1977)
Retrospective analysis of PCNSL outcomes at MSKCC
demonstrate that elimination of IT MTX did not affect
outcome in pts treated at a target dose of 3.5g/m2.
(Khan et al, J Neuro-oncol, 2002)
8gm/m2 produces higher cytotoxic levels in serum and
csf than IT mtx (Glantz et al, JCO 1998)

high-dose chemotherapy with autologous stem-cell
transplant (ASCT) in young & healthy pts.
Relapse rates:
50-60% in the 1st 2 yrs
