Bias and precision of methods for estimating the difference in restricted mean survival time from an individual patient data meta-analysis

BMC Medical Research Methodology, 2016
Background The difference in restricted mean survival time ( rmstD t ∗ $$ rmstD\left({t}^{\ast}\right) $$ ), the area between two survival curves up to time horizon t ∗ $$ {t}^{\ast } $$ , is often used in cost-effectiveness analyses to estimate the ...

Efficacy and Tolerability of Topotecan/Cyclophosphamide/Dinutuximab in Relapsed and Refractory High‐Risk Neuroblastoma: A Multi‐Institutional Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Chemoimmunotherapy with irinotecan, temozolomide, and dinutuximab (I/T/DIN) has emerged as first‐line therapy for relapsed/refractory (r/r) high‐risk neuroblastoma (HRNB) in North America. Topotecan and cyclophosphamide (T/C) are often used in combination with dinutuximab in the setting of lack of response, progression, or incomplete ...
