NECN Lung NSSG April 2012 Crude Incidence, a Local Issue: NSCLC Referrals (to PMM) since (n=1810) Treatment Intent: –Palliative – 83% –Radical – 17% 10% presented with brain metastases 24% of those with stage III disease have then developed brain metastases (after combined modality treatment up front) i.e. in my day to day practice: 215 patients with NSCLC + Brain metastases between –1 per fortnight

NECN Lung NSSG April 2012 Micro-Surgical resection or Stereotactic Radiosurgery (SRS)? For solitary metastasis – comparable outcomes –Kalkanis et al J. Neuro Oncology 2010; 96(1): Surgical series: superficial, larger, midline shift –Best results if complete en bloc resection –Where possible, avoid piecemeal resection Do less well if >9.5cm or if removed piecemeal

NECN Lung NSSG April 2012 Micro-Surgical resection or Stereotactic Radiosurgery (SRS)? SRS smaller (<3cm) Deep seated Less mid line shift Both (Sx or SRS) provide comparable local control and overall survival (ms >10m) Addition of WBRT – further intra cranial control; no further benefit seen in OS
