摘要 目的统计治疗前植入到肝脏肿瘤患者体内的,与治疗中用于追踪的金标数量并加以评价。方法2011年6月至2012年6月我中心利用射波刀为437例肝脏肿瘤患者实施了立体定向体部放射治疗(SBRT),治疗前在这些患者体内共植入1 586颗金标,每名患者植入的金标数量为2~9颗。对治疗中使用不同数量金标追踪的病例分别进行统计,并与植入时的病例进行对比。结果植入2颗金标的例数为25例,占总例数的5.72%;植入3颗和3颗以上的金标的例数为412例,占总例数的94.28%。治疗中利用2颗金标追踪的例数为97例,占总例数的22.20%;利用3颗和3颗以上金标追踪的例数为340例,占总例数的77.80%。金标的移位率为1.70%,利用率为90.62%。结论在治疗中使用2颗金标追踪的比例为22.20%,9.38%的金标在追踪没有使用,为此我们要不断提高金标植入的质量和数量,最大限度地降低2颗金标追踪的比例,提高金标利用率。
