摘要 目的:检测实体瘤骨转移患者尿Ⅰ型胶原交联氨基末端肽(uNTX)及血清骨碱性磷酸酶(sBALP)水平,评价其在实体瘤骨转移的临床意义。方法:选择2007年10月至2009年1月广州医学院附属肿瘤医院内二科住院化疗的实体瘤骨转移患者32例。在治疗前后分别以酶联免疫吸附法(ELISA)、小麦菌凝集素沉淀法测定uNTX、sBALP。随访骨相关事件(SREs)及生存状况。结果:实体瘤骨转移患者基线uNTX/Cr及sBALP水平明显高于正常,其浓度与骨转移负荷成正相关,与疼痛强度无显著相关。治疗3个月时uNTX/Cr及sBALP水平明显降低,而放射性核素全身骨显像(ECT)尚无明显改变;32例患者中,24例基线uNTX/Cr水平高于正常,治疗后15例降至正常,9例仍维持在较高水平,两者骨相关事件发生率为53%比89%(P=0.039);26例基线sBALP水平高于正常,治疗后16例降至正常,10例仍维持在较高水平,两者骨相关事件发生率为50%比90%(P=0.038)。uNTX/Cr,sBALP水平对生存率的影响无统计学意义。结论:骨代谢标记物uNTX、sBALP在恶性肿瘤骨转移的诊断,对治疗反应的监测及骨相关事件的预测方面具有一定的价值。
