Key result

LPL-positive patients had a significantly shorter median treatment-free survival time compared to LPL-negative patients (23 vs 88 months; P=0.002).

Why the study?

Does LPL mRNA expression predict prognosis and IGHV mutation status in patients with B Cell Chronic Lymphocytic Leukemia?

Population

50 patients with B Cell Chronic Lymphocytic Leukemia (CLL)

Design

Cohort

Overview

LPL mRNA expression measured via qPCR in whole blood is a valuable prognostic marker in CLL that correlates with IGHV mutation status and survival.

Study Design

Type

Observational (n=50)

Structured PICO

Does LPL mRNA expression predict prognosis and IGHV mutation status in patients with B Cell Chronic Lymphocytic Leukemia?

P
Population
50 patients with chronic lymphocytic leukemia evaluated for LPL mRNA expression as a prognostic marker.
E
Exposure
Measurement of lipoprotein lipase (LPL) mRNA expression using quantitative PCR (qPCR) in lysed whole blood and CD19-selected cells
O
Outcome
Association of LPL expression with IGHV mutation status, overall survival (OS), and treatment-free survival (TFS)surrogate

Main Result

Absolute Event Rate: 23% vs 88%

p-value: p=0.002

LPL mRNA expression measured via qPCR in whole blood is a valuable prognostic marker in CLL that correlates with IGHV mutation status and survival.

Cite This Study

Bockstaele et al. (2006) conducted an observational in Chronic lymphocytic leukemia (CLL) (n=50). LPL mRNA expression (LPL-positive) vs. LPL-negative was evaluated on Median treatment-free survival (months) (p=0.002). LPL-positive patients had a significantly shorter median treatment-free survival time compared to LPL-negative patients (23 vs 88 months; P=0.002).
