METHODS: A literature search was performed with PubMed and Medline by using the words vestibular schwannoma, acoustic neuroma, radiotherapy, and radiosurgery.
RESULTS: In small (<3 cm) VS, SRS offers a local control rate of >90%, which seems similar to microsurgery, with a favorable tolerance profile. Hypofractionated FSRT (three to five fractions) is a relatively recent modality and has shown similar outcomes to normofractionated FSRT. Hearing preservation may highly differ between studies, but it is around 65% at 5 years.
CONCLUSIONS: SRS and FRST are non-invasive treatment options for VS. SRS is often preferred for small lesions less than 3 cm, and FSRT for larger lesions. However, no randomized study has compared these modalities.
方法:使用PubMed和Medline进行文献检索,使用前庭神经鞘瘤,听神经瘤,放射治疗,和放射外科。
结果:在小(<3厘米)VS中,SRS提供>90%的本地控制率,这看起来类似于显微外科手术,具有良好的公差轮廓。低分割FSRT(三到五个部分)是一种相对较新的模式,并且显示出与正常分割FSRT相似的结果。不同研究之间的听力保护可能有很大的不同,但5年时约为65%。
结论:SRS和FRST是VS的非侵入性治疗选择。对于小于3厘米的小病灶,SRS通常是首选。和FSRT用于较大病变。然而,没有随机研究对这些模式进行比较.
