Sharon - as you know my sister Cathy was treated at Sunnybrok (the other major cancer centre in Toronto. She had weeks and weeks of radiation but the cancer is still there. We talked to a medical oncologist about chemo and he basically told us the same thing - that there is no definitive chemo regimen that works for head and neck cancer - that is why you see so many variations in the chemo drugs people are on. Cathy has been referred to Princess Margaret so it will be interesting to see what they say at our appointment on tuesday.
