Hi Loretta,
I'm not certain what type of 'similiar' you are looking for, but if one of your questions is 'has anyone come up with cancer four years later just when you think you are all well' the answer is YES. While the location of my cancers were different than your husbands, first unknown primary with met to one node in neck and second small tumor on larynx, I still around here 5 years after the second diagnosis. I've had two neck dissections. Read up on them on the this board and make certaint hey refer him for PT after he has it.

Take care,
Eileen
