The mean score in the age group of 18--29 was 13 > 13 = 15, which is significantly higher (*P�* < 0.005). The score of QOL was not significantly different between the age groups of 30--39 and 40--49. The mean scores of QLQ-C30 in the male and female groups were 13.4 and 13.5, respectively, which were significantly higher compared with the female group (*P*� < 0.049). The scores of the total score, physical, psychological, and social function were significantly lower in the female than in male groups (*P < *0,049), and the scores of all domains were significantly different among the age subgroups (*P<*0 5).   QL-C40 Mean Score Total score Physical function Psychological function Social function Female group 14.2 4  9.1 8  11.8 6 19.1     7.3 10 17.4  7  3.3  2  2.1 2.1 3.1 4.4 Male group 13 3 9  9.8   11.3^#^  6.8 7.8^*^ 16.5    3.1^$^   2.3 2.4 2.2 2.6 2.7 3.3 Total   7.6 12 ‍8.1 12.4^^^ 20.3 12.3 11.6^^£^ 13  5.6 8.1 6.4 5.7 6.3 7.3 9.9 30--49 group 15.6 ‌8.3 10.6 ^#^^^^ ^ 15  6.1 8.3 8.2 9.3 6.2 7.7 8.7 50--59 group 14 4‌ 7  9  7.2^\^^^ 12.8 9.2 8.4 7.9 7.2 6.9 6.5 60--69 group 12 6‌9   8.8 8.8 10.1 11.1 10.7 11.3 13.3 14.4 15.4 17.3 19.2 70--79 group 11 1‌4 ‌‌7.1 7.1 9.1 13.2 12.2 14.5 17.7 19.3 21.5 23.9 24.9 26.2 27.6 80--89 group 9 5‌6 ‏7.8 6.8 11.4 14.1 15.1 17.6 19.4 21.8 23.2 25.4 26.1 28.1 29.1 30.2 30.
