Abstract

Response monitoring using fluorodeoxyglucose positron emission tomography acquired together with low dose computed tomography (FDG-PET/CT) textural features has potential in targeted treatment with erlotinib in non-small cell lung cancer (NSCLC) patients. Patients with substantial decrease of metabolic activity during erlotinib treatment will probably benefit from continued treatment. However, various aspects of the method (quantification tools, cut-off values, etc.) need to be standardized before the software becomes widely available in a similar manner as standardized uptake value (SUV) measurements. Heterogeneity on FDG-PET/CT opened an additional window for innovation but simultaneously a new challenge for molecular hybrid imaging.

摘要

使用与低剂量计算机断层扫描(FDG-PET/CT)纹理特征一起采集的氟脱氧葡萄糖正电子发射断层扫描进行反应监测,在非小细胞肺癌(NSCLC)患者中使用厄洛替尼进行靶向治疗具有潜力。在厄洛替尼治疗期间代谢活性大幅下降的患者可能会从持续治疗中获益。然而,在该软件以与标准化摄取值(SUV)测量类似的方式广泛可用之前,该方法的各个方面(量化工具、临界值等)需要标准化。FDG-PET/CT上的异质性为创新打开了一个额外的窗口,但同时也给分子混合成像带来了新的挑战。
