  • Historically, some of the highest incidence rates for colorectal cancers have been in “more developed” regions. However, approximately 45% of these occur in “less developed” regions, representing 9-10% of cancers in those populations.
  • Since different regions of the world, both among and within countries, differ with respect to resource access, ASCO has established a process for stratifying guidelines according to resource availability (basic, limited, enhanced and maximal – See Table 1). This framework emphasizes that variations occur not only between but also within countries—for example, between rural and urban areas.
