Aims: Treatment with stereotactic radiosurgery/radiotherapy (SRS/SRT) is standard practice in selected patients with small numbers of brain metastases (BMs). It is less accepted in those with ≥5 BMs, due to the lack of a prospective evidence base. While randomised trials are ongoing, we present the experience of a single UK cancer centre in using SRS/SRT for patients with 5 or more BMs without whole brain radiotherapy (WBRT).

Aims: Tissue V12Gy (total brain volume receiving 12Gy including target) can predict for late toxicity in single target benign disease treated with stereotactic radiosurgery (SRS). The value of this metric remains uncertain for multiple brain metastases. This retrospective cohort study reports the outcomes and evaluates the predictors of toxicity in patients with four or more brain metastases treated with single-fraction SRS.

Article Synopsis
  • - This study aims to determine the safe planning margins (PRV) for protecting optic nerves during CyberKnife stereotactic radiosurgery (SRS) due to potential motion of the nerves during treatment.
  • - MRI scans of healthy volunteers were used to assess optic nerve motion in various directions, leading to the calculation of two different PRV margins: a non-isotropic margin of 3mm in the left/right direction and an isotropic margin of 1mm when patients maintain a neutral gaze.
  • - The findings suggest that incorporating these PRV margins in CyberKnife treatment plans is crucial to minimize risks to the optic nerves, particularly in patients with perioptic lesions like sphenoid wing meningiomas.

This study examined the effects of three external verbal cues on countermovement rebound jump (CMRJ) performance. Twenty-five recreational athletes completed nine jumps with distinct height, velocity and combined cue focus. A general linear model analysis of variance was used to evaluate systematic bias between conditions ( < 0.

Introduction: BCL-2 family proteins are important for tumour cell survival and drug resistance in multiple myeloma (MM). Although proteasome inhibitors are effective anti-myeloma drugs, some patients are resistant and almost all eventually relapse. We examined the function of BCL-2 family proteins in stromal-mediated resistance to carfilzomib-induced cytotoxicity in MM cells.
