. Patients whose swallowing improved gained significantly more weight (P<0.0001). Swallowing (P = 0.0009) was significantly improved in radiological responders but not weight (P = 0.06); when radiological non-responders were separated into stable and progressive disease, patients with progressive disease were identified as failing to gain weight (P = 0.005). Both swallowing (P<0.0001) and weight gain (P<0.0001) were better in patients undergoing surgery. The use of changes of weight (P = 0
