The multistep cancer progression model he developed, popularly called the “Vogelgram,” is now taught around the world. Now that most of the genetic changes responsible for human cancer have been identified, Vogelstein’s focus has turned toward the development of therapies and diagnostic methods for earlier cancer detection.

A quantitative model of carcinogenesis based on methods from population biology and game theory demonstrates normal cells in vivo occupy a ridge-shaped maximum in a well-defined tissue fitness landscape, a novel configuration that allows cooperative coexistence of multiple cellular populations.

In this model,cancer initiation occurs due to inactivation of the gatekeeper network module (e.g.,module I). The classic Vogelgram multistep model for CRC indicates tumor suppressor gene, adenomatous polyposis coli (APC) gene acts as a gatekeeper and alterations in the APC/Wnt-signaling trigger adenoma−carcinoma sequence.

‘Vogelgram ’ Colon cancer The model is based on the understanding that colon cancer is the result of a series of genetic mutations in key genes. This includes loss of APC and TP53 and activation of KRAS. Since its initial release, this model has seen many revisions.

In 1990, Fearon and Vogelstein proposed a progressive development model of colon cancer and presented some of the key genetic changes associ-ated with the stages of progression (Fearon and Vogelstein,1990; Grady,2004) (Figure 1). The 'Vogelgram' represents a word model, grounded in the linear logic that is typical of this approach.

sequence, popularly called the “Vogelgram”. 15,16 Using colorectal lesions of different stages Vogelstein and colleagues created a model showing that CRC is a genetic disease marked by the accumulation of genetic changes. This multistep model indicates the crucial molecular events that are taking place

Stem cells (j = 3 telomeres) grow linearly, progenitor cells (j = 2 telomeres) in t2, and differentiated cells (j = 1 telomere) in t3.
