Abstract

Serum levels of pro-[vascular endothelial growth factor (VEGF)] and anti-[thrombospondin-1 (TSP)] angiogenic cytokines were prospectively measured in a phase II trial of chemoimmunotherapy (CIT) for chronic lymphocytic leukaemia (CLL) patients (n = 56). Pretreatment VEGF levels were lower among patients who achieved complete remission (CR) or nodular partial remission (nPR) relative to those with partial remission (PR) or stable/progressive disease (median 122.0 pg/ml vs. 246.8 pg/ml; P = 0.03). VEGF:TSP ratio was lower (anti-angiogenic phenotype) among patients who achieved CR/nPR. The pretreatment VEGF:TSP ratio also correlated with overall survival (P = 0.008). A pro-angiogenic profile appears associated with diminished response and inferior survival in CLL patients receiving CIT.

摘要

在一项针对慢性淋巴细胞白血病(CLL)患者的化疗免疫治疗(CIT)的 II 期试验中,前瞻性地测量了血清中促血管内皮生长因子(VEGF)和抗血栓素-1(TSP)血管生成细胞因子的水平(n=56)。与部分缓解(PR)或稳定/进展性疾病患者相比,达到完全缓解(CR)或结节部分缓解(nPR)的患者的 VEGF 水平较低(中位数 122.0 pg/ml 与 246.8 pg/ml;P=0.03)。达到 CR/nPR 的患者的 VEGF:TSP 比值较低(抗血管生成表型)。VEGF:TSP 比值也与总生存期相关(P=0.008)。在接受 CIT 的 CLL 患者中,促血管生成谱似乎与反应减弱和生存不良相关。
