Difference of survival comparing conventionally fractionated radiotherapy with conventionally fractionated radiotherapy plus simultaneous chemotherapy using cisplatin, carboplatin, mitomycin C, and 5-fluorouracil as single drug or combinations of 5-FU with a platin-derivate (Group 1a). OS = Overall survival; * = 95% confidence limits of 2 year overall survival; delta months = differences of median overall survival; LCL = lower confidence limit of median survival; UCL = upper confidence limit of median survival; N = number of patients.
