Abstract

The effect of photodynamic therapy (PDT) on interstitial fluid pressure (IFP), tumour volume and water content was measured in melanomas grown in hamsters. Unlike control tumours, treated tumours exhibited a 40-60% increase in volume at 1, 3 and 6 h post PDT. IFP also increased at 1 and 3 h after PDT, but decreased to 50% of control value after 24 h, presumably as a result of PDT-induced microcirculatory impairment.

摘要

在仓鼠体内生长的黑色素瘤中,测量了光动力疗法(PDT)对间质液压力(IFP)、肿瘤体积和含水量的影响。与对照肿瘤不同,接受治疗的肿瘤在PDT后1、3和6小时体积增加了40%-60%。PDT后1和3小时IFP也增加,但24小时后降至对照值的50%,这可能是PDT诱导的微循环损伤所致。
