How do you approach at-risk draining nodes and the bronchial stump in PORT volumes for margin-positive, pN0 NSCLC?   

NCCN guidelines as of the May 2021 update state "In PORT, the CTV includes the bronchial stump and high-risk draining lymph nodes stations."  Would you now only irradiate the +margin region while omitting PORT to the bronchial stump (if not the +margin site) & at-risk nodes?
