My husband Johnny was diagnosed stage 4 squamous cell carcinoma base of the tongue. He had a 9 hour surgery they removed 1/3 of the base of his tongue, 18 nodes 3 were positive. Following surgery he had 30 radiation treatments as well as Erbitux. On 8/23/10 he underwent 18.5 hour surgery to remove the tumor, nodes(0 pos.) and Epiglottis/Tongue reconstruction with free radial forearm flap on 8/23/10. The surgeon sent 18 frozen sections to the pathologist during the surgery. The day before he was sent home we were told the pathologist made an error and one of the margins from the back of his mouth had microscopic cancer cells.How could this happen? Has this happened to anyone else? We see the chemo doc on 9/27/10. What type of chemo will they use? When he is healed another surgery
