Ibrutinib and rituximab versus fludarabine, cyclophosphamide, and rituximab for patients with previously untreated chronic lymphocytic leukaemia (FLAIR): interim analysis of a multicentre, open-label, randomised, phase 3 trial.

Background: The approval of Bruton tyrosine kinase (BTK) inhibitors in patients with previously untreated chronic lymphocytic leukaemia (CLL) was based on trials which compared ibrutinib with alkylating agents in patients considered unfit for fludarabine, cyclophosphamide, and rituximab, the most effective chemoimmunotherapy in CLL. We aimed to assess whether ibrutinib and rituximab is superior to fludarabine, cyclophosphamide, and rituximab in terms of progression-free survival.

Methods: This study is an interim analysis of FLAIR, which is an open-label, randomised, controlled, phase 3 trial in patients with previously untreated CLL done at 101 UK National Health Service hospitals.

Integrative analysis of spontaneous CLL regression highlights genetic and microenvironmental interdependency in CLL.

Spontaneous regression is a recognized phenomenon in chronic lymphocytic leukemia (CLL) but its biological basis remains unknown. We undertook a detailed investigation of the biological and clinical features of 20 spontaneous CLL regression cases incorporating phenotypic, functional, transcriptomic, and genomic studies at sequential time points. All spontaneously regressed tumors were IGHV-mutated with no restricted IGHV usage or B-cell receptor (BCR) stereotypy.

Preclinical evaluation of vascular-disrupting agents in Ewing's sarcoma family of tumours.

The effects of the tubulin-binding vascular-disrupting agents (VDAs), combretastatin A4 phosphate (CA4P), OXi4503/CA1P and OXi8007, in subcutaneous mouse models of the Ewing's sarcoma family of tumours (ESFTs) have been investigated alone and in combination with doxorubicin. Delay in subcutaneous tumour growth was observed following treatment of mice with multiple doses of OXi4503/CA1P but not with CA4P or OXi8007. A single dose of OXi4503/CA1P caused complete shutdown of vasculature by 24h and extensive haemorrhagic necrosis by 48h.

Outreach monitoring service for patients with indolent B-cell and plasma cell disorders: a UK experience.

Disease progression occurs in over 1% of monoclonal gammopathy of undetermined significance, monoclonal B-cell lymphocytosis and early stage chronic lymphocytic leukaemia patients every year therefore regular monitoring is indicated. We assessed the efficacy of an outreach service to replace clinic monitoring using local phlebotomy with central haematologist review of laboratory parameters and symptoms identified by a patient self-assessment questionnaire. The service was used by 299 patients for 2 years and provided accurate monitoring, improved patient satisfaction, support for primary care and reduced the burden on haematology clinics without an increase in inter-assessment admissions due to disease progression.

Vascular endothelial growth factor: a therapeutic target for tumors of the Ewing's sarcoma family.

Purpose: We have reported previously that intratumoral microvessel density (MVD) is a significant prognostic indicator of event-free survival in the Ewing's sarcoma family of tumors (ESFT). Here, the angiogenic growth factor expression profile and its relationship with MVD has been investigated in ESFT.

Experimental Design And Results: Using ESFT model systems, the potential of these factors as therapeutic targets has been evaluated.
