As you can see, development of the 2007 Multiple Primaries & Histology Coding Rules was not a short term or superficial effort. In all, it will have taken four years from organizing the committee to putting the changes into practice. After the committee work was completed, all the site-specific rules as well as the general rules were thoroughly beta tested and a cadre of trainers has been trained.
