Central nervous system (CNS) relapse following R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone) occurs in 2-5% of patents with diffuse large B-cell lymphoma (DLBCL). Many patients aged ≥70 years are unsuitable for high-dose methotrexate (HDMTX) prophylaxis and therefore often receive stand-alone intrathecal prophylaxis. The CNS international prognostic index (CNS-IPI) is a clinical CNS relapse risk score that has not specifically been validated in elderly patients. ⋯ When excluding HDMTX (n = 31) patients, there remained no change in unadjusted/adjusted CNS relapse for intrathecal prophylaxis effect according to CNS-IPI. CNS-IPI is valid in elderly R-CHOP-treated DLBCL patients, with the highest risk in those with CNS-IPI 6 and R/A involvement. We observed no clear benefit for stand-alone intrathecal prophylaxis but observed an independent increased risk of infection-related admission during R-CHOP when intrathecal prophylaxis was administered.
