Relapse in the central nervous system (CNS) following initial treatment of diffuse large B-cell lymphoma (DLBCL) is an uncommon but serious complication. This single centre retrospective study investigated the rate of CNS relapse in patients with DLBCL who received standardised intrathecal (IT) chemoprophylaxis. ⋯ The CNS relapse rate in this cohort of patients with primary DLBCL was low at 1.1%. This retrospective analysis demonstrates in a homogeneous group of DLBCL patients that a relatively low-intensity IT chemoprophylaxis regimen given according to site-based risk can be associated with a low risk of CNS relapse.

Letrozole after 5 years of adjuvant tamoxifen results in a significant reduction in risk of recurrence from estrogen receptor (ER) positive breast cancer. An individualized estimate of the risk of relapse and death after 5 years of tamoxifen could improve decisions regarding extended hormonal therapy. ⋯ T and N stages predicted late relapse and death from breast cancer in a population-based cohort of postmenopausal women. Risk estimates reported herein may be used to optimize decision making regarding adjuvant therapy after 5 years of tamoxifen.
