What are the indications for radiation after cord stripping for early-stage glottic cancers?

Not sure I understand the question to be honest. Regardless, vocal cord stripping is not a common procedure these days. My surgical colleagues say it is only used for benign epithelial lesions (eg. polyps). And a quick PubMed search for "vocal cord stripping" shows studies dating back to 1945!

I've only seen VC stripping done in one or two patients, and not for true cancer. So in your case, I am guessing stripping was done for a "polyp" and returned a surprise diagnosis of cancer.

If there is in...

Multiply recurrent, questionable or positive margins. The ENT can hopefully help with the "questionable" margins.
