低级别胶质瘤英语

低级别胶质瘤英语
Low-grade glioma, also known as low-grade astrocytoma,
is a type of brain tumor that grows slowly and is less aggressive than high-grade gliomas. These tumors can occur in any part of the brain and are often found in the cerebral hemispheres. They are typically slow-growing and may not cause symptoms for many years.
Low-grade gliomas are classified as World Health Organization (WHO) grade I or II, based on their appearance under a microscope and their growth pattern. Grade I tumors are the least aggressive, while grade II tumors are
slightly more aggressive but still considered low-grade.
Symptoms of low-grade gliomas can vary depending on the location of the tumor, but may include headaches, seizures, changes in vision or hearing, and cognitive or behavioral changes. However, some individuals with low-grade gliomas may not experience any symptoms until the tumor grows
larger or affects surrounding brain tissue.
Diagnosis of low-grade gliomas often involves a combination of imaging tests such as MRI or CT scans, as
well as a biopsy to examine the tumor cells under a microscope. Once diagnosed, treatment options for low-grade gliomas may include surgery to remove as much of the tumor as possible, radiation therapy, and chemotherapy.
In some cases, a "watch and wait" approach may be recommended, particularly for slow-growing tumors that are not causing significant symptoms. This approach involves regular monitoring with imaging tests to track the growth of the tumor and assess whether treatment is necessary.
Overall, the prognosis for individuals with low-grade gliomas can vary depending on factors such as the age of the patient, the location and size of the tumor, and the specific characteristics of the tumor cells. While these tumors are generally considered less aggressive than high-grade gliomas, they can still have a significant impact on quality of life and may require ongoing medical management.
低级别胶质瘤，也称为低级别星形细胞瘤，是一种生长缓慢且比高级别胶质瘤更不具侵袭性的脑肿瘤。

这些肿瘤可以发生在大脑的任何部位，通常在大脑半球中发现。

它们通常生长缓慢，可能多年不会出现症状。

低级别胶质瘤根据在显微镜下的外观和生长模式被分类为世界卫
生组织（WHO）I或II级。

I级肿瘤是最不具侵袭性的，而II级肿
瘤略微具侵袭性，但仍被认为是低级别的。

低级别胶质瘤的症状可能因肿瘤的部位而有所不同，但可能包括
头痛、癫痫发作、视力或听力变化以及认知或行为变化。

然而，一
些患有低级别胶质瘤的个体可能在肿瘤长大或影响周围脑组织之前
不会出现任何症状。

低级别胶质瘤的诊断通常包括结合影像检查，如MRI或CT扫描，以及活检来在显微镜下检查肿瘤细胞。

一旦诊断出，低级别胶质瘤
的治疗选项可能包括手术尽可能切除肿瘤、放射疗法和化疗。

在某些情况下，可能会建议采取“观察等待”的方法，特别是对
于生长缓慢且不引起明显症状的肿瘤。

这种方法包括定期监测影像
检查以跟踪肿瘤的生长，并评估是否需要治疗。

总的来说，患有低级别胶质瘤的个体的预后可能因患者年龄、肿
瘤的部位和大小以及肿瘤细胞的特定特征等因素而有所不同。

尽管
这些肿瘤通常被认为比高级别胶质瘤更不具侵袭性，但它们仍可能
对生活质量产生重大影响，并可能需要持续的医疗管理。
