They also found that chronic Dll4 blockade was associated with the development of vascular neoplasms in rats in a dose-related manner. To be considered malignant, evidence is required to show that the tumours do not show involution on the discontinuation of Dll4 blockade and show aggressive local invasion and/or distant metastasis, which was not the case here. These observations were not reported in other species such as mice and monkeys, and a histopathological study of the natural history of these tumours, with continued therapy and on cessation of therapy, is critical to inform their behaviour. However, these findings will need to be taken into account in monitoring trials.

他们还发现,在大鼠,长期使用Dll4阻断剂与血管肿瘤的发展呈剂量依赖性相关。被认为是恶性的,需要证据显示中止使用Dll4阻断剂不会导致肿瘤退化,并显示进展性的局部浸润和/或远处转移,但是这里不是这样的。这些观察结果未曾在其他物种如老鼠和猴子上报道过,这些肿瘤(连续治疗和中止治疗)自然史的组织病理学研究对获得该阻断剂的表现是至关重要的。然而,在监测的临床试验中需要虑这些发现。
