Lymph node spread

My husband has a laryngectomy last August and two PET scans have just shown cancer in lymph nodes in his neck and thoracic area. Can anyone offer any insight about treatment? The one doctor said further tests would be need to see if thoracic nodes are even operable. Radiation is out and chemo sounds pretty iffy. My husband is inclined, in any case, to skip further treatment. One doctor we spoke to gave pretty sketchy information and I hope to contact his surgeon in the next day or so. (He was busy.) Can anyone tell me where we might expect next spread of the cancer —is the lung the likely place? And ANY information on prognosis (doctor said 6-12 mos.) such as what kind of care he will need and how quickly. I’ve been scanning the internet but can’t seem to find what I’m looking for. Any help would be appreciated.
