“ 多形性星形细胞瘤”此诊断名词没见过?是不是属于分化不良或间变性星形细胞瘤啊？如是的则为WHOⅢ级。

处理：应根据肿瘤本身的病理分级，病人的年龄和一般状况，肿瘤的部位等给与恰当临床处理如外科手术切除，放疗，化疗等。请根据病情咨询相关临床专家。

预后：随访资料表明分化不良的星形细胞瘤(WHOⅢ级)生存年限为2-5年。

非常感谢！

一楼所提供的可能是影像学诊断。朋友提供的，具体不明……

 If you are talking about PXA, which is a B9 tumor with great Px.I need to see the slides if possible.

Please clearify your Dx.

Pleomorphic xanthoastrocytoma (多形性黄色星形细胞瘤) is, by WHO criteria, a grade II neoplasm in most cases. It usually affects young adults or children with very characteristic histopathology and benign a biologic behavior. Surgical total resection should be the treatment of choice. No radiation treatment is needed after total and subtotal resection of the lesion. Very rarely, atypical PXA with necrosis, vascular/endothelial proliferation, and brisk mitotic activity is seen and is known as atypical PXA. This rare variant is more likely to recur locally, but has not been classified as a WHO grade III lesion yet.
