Knowledge on long-term effects in melanoma patients is limited due to .Despite the continuous implementation of stereotactic radiosurgery (SRS) for patients with limited (≤4) brain metastases from various solid tumours1 and despite the increasing evidence of neurocognitive toxicity from whole brain radiotherapy (WBRT),2 patients with brain metastases from small-cell lung cancer (SCLC) are still considered . For some patients, palliative care alone may be appropriate.These results should change current practice of WBRT alone for all people with multiple brain metastases, and SRS should be added as upfront treatment for selected patients.16 Moreover, postoperative radiotherapy after surgical resection is important in reducing the risk of recurrence but does not impact overall survival (OS) or patient function.Single-fraction stereotactic radiosurgery (SRS) without additional whole-brain radiotherapy (WBRT) is a national and international standard for local radiotherapy of limited brain metastases (1–4 brain metastases) [1, 2].Patients with brain metastases from solid cancers who had at least 1 lesion treated with preoperative SRS and underwent planned resection were included.

Purpose Prospective studies have demonstrated increased local control with the addition of a radiosurgery (SRS) boost to whole-brain irradiation (WBRT) in patients with brain metastases.This review focuses on the management of brain metastases.Additionally, patients treated with adjuvant SRS experienced significantly less cognitive deficits at 6 months (41% vs 52% WBRT, p < 0.2 months, the rate of cognitive deterioration at 3-months was 63. There was no difference in quality-adjusted life years, survival or steroid use in either arm. There is a lack of prospective data and insufficient real-world data to draw conclusions on toxicity.3 prospective randomized trial of 194 patients with one resected brain metastasis and a resection cavity less than 5 cm in maximal size who were randomly assigned to either SRS (12 to 20 Gy) to WBRT (30–37.Regarding cognitive side effects, it is better tolerated than WBRT without .Purpose This study aimed to assess health-related quality of life (HRQoL) in patients with brain metastases treated with stereotactic radiosurgery (SRS) and to identify factors associated with this.
