"A low salvage rate of only ~50% at 2 years was found. Calculated numbers of patients needed to treat with postoperative radiation after initial surgery, in order to avoid recurrence and tumor-specific death, suggest a rather generous use of adjuvant irradiation, usually with simultaneous chemotherapy."

.... while the results are pretty convincing, it will take more (and independent) confirmation (also in the US).

quite often you find a cautious tone (i.e. suggest) in a scientific article. Unfortunately, the cranks do not stay away from absolutes.
