RISK FACTORS
Larger nodule size
Increasing n° of N+
Preoperative 1-second forced expiratory volume (FEV1)
Shorter DFI (resected pts)
If FEV1 is 60% to 70% of predicted normal, long-term survival decreases by about 33%.
ConclusionsBecause pulmonary metastasectomy forrenal cell carcinoma is safe, survival depends on complete resection of pulmonary disease and adequate pulmonary reserve.
good long-term results after metastasectomy
low morbidity and long-term efficacy
pulmonary surgery with systematic lymph node dissection is indicated

Convenience of single fraction treatment Patient
Caregiver
There is no evidence to suggest that a single 8 Gy fraction provides inferior pain relief to a more prolonged course of treatment in painful spine
Radiotherapy for bone mets
Meta-analysis of reported randomized trials shows no significant difference in complete and overall pain relief between single and multifraction palliative RT for bone metastases.

Brain metastases
The presence of brain metastases is a particularly important consideration when selecting treatment
Patients with brain metastases are often excluded from clinical trials due to their poor prognoses2-4
Brain metastases occur in 4-17% of patients with RCC5
RCC with brain metastases has been associated with a median survival of 7 months3,4
Untreated brain metastases have a survival of around 3.2 months

166 RCC patients with brain metastases treated with SRS at the Cleveland Clinic between 1996 and 2010. Results: local control: 90% In 38% of patients there were additional distant CNS metastases at a median of 12.8 months .The median TTP (either local or distant) 9.9 m.
Median OS for pts treated with targeted agents (n = 24 vs 37) was 16.6 vs 7.2 mos Freedom from local failure at 1 year: 93% vs 60% Multivariate analysis the use of targeted agents was the only factor that predicted for
improved survival.
Targeted agents appear to improve overall survival andlocal control in patients with brain metastases from RCC
treated with GKS.

5-year actuarial rate of brain mets: 40% vs 17%, (P < .001). TKI treatment lower incidence of brain mets in Cox multivariate analysis Lung mets increased the risk of brain mets

Patients with metastatic renal cell carcinoma should be considered for multimodal therapy
A proportion of patients will achieve long-term survival with aggressive surgical resectionIn the treatment of lung metastases, metastasectomy has a low morbidity and long-term efficacy Sunitinib appeared more effective than sorafenib in delaying mean time to progression or onset of bone lesionsConcomitant use of antiresorptive agents and TKI or mTOR inhibitors probably improves efficacy of bone targeted therapyLocal treatments are in use to control symptoms in brain mets despite the low radiosensityTKIs seems to be effective in the control of brain mets without high risk of bleeding
