For locally advanced NSCLC with additional synchronous NSCLC primaries in the same lung or lobe, what is your approach to definitive therapy?  

E.g. One NSCLC with N2 disease, and additional ipsilateral small nodule that is a biopsy-proven second primary. When do you consider SBRT to a nodule vs incorporating all into the chemoradiation fields?
