  1. This Bowker Test shows the distribution of subtypes of Taneichi-Score before and 3 months after RT. The evaluation of the distribution of subtypes A to G shows in some patients minor changes in the direction of improvement over the course of time. Deterioration occurs in no cases, improvement in 18% (n = 8). No change is seen in 82% (n = 37) of the patients who were still alive more than 3 months after RT
