For gross supraclavicular disease in lung cancer, do you cover full dose to the involved lymph node with margin or to the entire supraclavicular fossa?  

Sometimes the supraclav area has smaller nodes, that are difficult to palpate. As such, I treat the entire sc fossa...cost is little and recurrence is very difficult to treat. Dose fall off with a margin on a single palpable node may cause a local failure.

Nodes+margin. Brachial plexus constraints would be an issue I'd imagine trying to take the whole region to full dose (if going >60-63)
