To be honest I'm not sure - so you've had the surgery - there are still positive margins - i would push for radiation, and a combination of chemo (Erbitux, and cisplatin). If your cancer is HPV related - Erbitux may not be necessary - but you should definitely have rads and chemo. Erbitux is shown to work better on non HPV cancers. But cisplatin is the gold standard and is effective (as is the older drug carboplatin). If the cancer hasn't metastasized (even if it as actually) then it's worth a shot - there are many stage 4 survivors here. And staging is just a number, as are prognosis percentages - both are a melting pot of people with different medical histories, habits, ages, medical treatments, and differentiations. this is all about you - as you are an individual. Your outcome is specific to you and your story is unique. People with stage one have passed on and people with stage 4 are still around - there are no guarantees - That said - one thing is for certain - no treatment, generally has a 100% mortality rate. Have your drs hit it with both barrels ASAP. Hugs - welcome - and much prayers and luck being sent to you.
