For NSCLC patients who are polymetastatic who then become and remain oligometastatic, is there a role for local ablative RT to the primary and metastatic sites?

The med oncs ask if we could treat those, and I generally will on the theory that these sites might have a different biol...

Remember that the @Gomez trial from MDACC (Gomez et al., PMID 31067138) enrolled patients with 3 or fewer lesions AFTER 3 months of first line systemic therapy - so someone could have 10 disease sites, and if 7 resolved on first line systemic they could still be included - relevant especially f...

However, only 36% had better than stable disease response (9 patients in both arms) thus, I think only a handful of patients would qualify as trul...
