Association between Pretreatment Serum High-density Lipoprotein Cholesterol and Treatment Outcomes in Patients with Locoregionally Advanced Nasopharyngeal Carcinoma Treated with Chemoradiotherapy: Findings from a Randomised Trial.

ABSTRACT: Background: To investigate the relationship between the pretreatment serum lipid concentrations and the clinical outcomes in patients with locoregionally advanced nasopharyngeal carcinoma (NPC) who were treated with a combination of chemotherapy and radiotherapy. Methods: From August 2002 to April 2005, 400 patients with stage III or stage IVa nasopharyngeal carcinoma were recruited for a randomised clinical trial of induction chemotherapy combined with radiotherapy or concurrent chemoradiotherapy. Pretreatment serum lipid concentrations were examined in 342 patients. Both univariate and multivariate analyses were conducted to investigate the association of serum lipid levels with different treatment outcomes. Results: The 5-year failure-free survival rate for the low- high-density lipoprotein cholesterol (HDL-C) and high-HDL-C groups was 52.1% and 65.5%, respectively (p=0.017), and the 5-year overall survival rate was 64.7% and 72.5%, respectively (p=0.094). The pretreatment serum level of HDL-C was a favourable prognostic factor of overall survival and failure-free survival in a Cox regression model with HR 0.65 (95% CI 0.43-0.97; p=0.036) and 0.60 (95% CI 0.41-0.88; p =0.008). No significant correlation was observed between the prognosis of patients with NPC and serum levels of total cholesterol (TC), triglyceride (TG), or low-density lipoprotein cholesterol (LDL-C). Conclusions: The pretreatment serum level of HDL-C was an independent prognostic factor for patients with locoregionally advanced nasopharyngeal carcinoma who were treated with chemoradiotherapy.

Project description:Background MEDI6012 is recombinant human lecithin cholesterol acyltransferase, the rate-limiting enzyme in reverse cholesterol transport. Infusions of lecithin cholesterol acyltransferase have the potential to enhance reverse cholesterol transport and benefit patients with coronary heart disease. The purpose of this study was to test the safety, pharmacokinetic, and pharmacodynamic profile of MEDI6012. Methods and Results This phase 2a double-blind study randomized 48 subjects with stable coronary heart disease on a statin to a single dose of MEDI6012 or placebo (6:2) (NCT02601560) with ascending doses administered intravenously (24, 80, 240, and 800 mg) and subcutaneously (80 and 600 mg). MEDI6012 demonstrated rates of treatment-emergent adverse events that were similar to those of placebo. Dose-dependent increases in high-density lipoprotein cholesterol were observed with area under the concentration-time curves from 0 to 96 hours of 728, 1640, 3035, and 5318 should be: mg·h/mL in the intravenous dose groups and 422 and 2845 mg·h/mL in the subcutaneous dose groups. Peak mean high-density lipoprotein cholesterol percent change was 31.4%, 71.4%, 125%, and 177.8% in the intravenous dose groups and 18.3% and 111.2% in the subcutaneous dose groups, and was accompanied by increases in endogenous apoA1 (apolipoprotein A1) and non-ATP-binding cassette transporter A1 cholesterol efflux capacity. Decreases in apoB (apolipoprotein B) were observed across all dose levels and decreases in atherogenic small low-density lipoprotein particles by 41%, 88%, and 79% at the 80-, 240-, and 800-mg IV doses, respectively. Conclusions MEDI6012 demonstrated an acceptable safety profile and increased high-density lipoprotein cholesterol, endogenous apoA1, and non-ATP-binding cassette transporter A1 cholesterol efflux capacity while reducing the number of atherogenic low-density lipoprotein particles. These findings are supportive of enhanced reverse cholesterol transport and a functional high-density lipoprotein phenotype.
