My husband is a childhood cancer survivor (Ewing's soft tissue sarcoma of the head and neck). Now 30+ years later, he has developed squamous cell carcinoma at the radiation site. He underwent major free flap surgery for it this summer, but now there is concern that it might be back (there was a "positive margin" left). The doctor has mentioned re-irradiating him with over 60 rads in an even larger area than the original radiation. This is through clinical trial, as they do not know how the tissue will react, whether radionecrosis will be sped up exponentially or if it will give him an even worse quality of life than he already has, or whether it will even be effective in killing the cancer for good. Has anyone here undergone reirradiation or know someone who has?
