Research Abstract

In this study we evaluated individual factors which influenced on waiting time for breast cancer surgery. Our study showed the maximum waiting time of Stage3 was shorter than those of the lower Stages, although the multiple regression analysis did not show the significant coefficient. This result suggests that Japanese surgeons are likely to place priority on severer cases. Although we tried to apply queuing theory to this data, we gave up it because inflow rate was higher than outflow rate in some intervals.
