Figure: A Genetic Model for Colorectal Tumorigenesis. This is an The 'Vogelgram' represents a word model, grounded in the linear logic that is typical of this approach. It can, however, form the schematic framework for mechanistic, quantitative models that These observations fit with classic combinatorial models of cancer development, such as the ‘Vogelgram’, in which bowel cells must gather a particular set of mutations to make the leap toward cancer, although these mutations do not necessarily have to happen in a specific order. The new data presented by Cheng et al. provide further evidence for a revision of the classic model of colon cancer evolution (the “Vogelgram”).

Colorectal cancer (CRC) represents the second most diagnosed form of cancer disease in Germany (Robert Koch Institute 2011/2012). In most cases, the disease follows the “classic” adenoma-carcinoma sequence, and underlying genetic alterations of disease driver pathways such as WNT, KRAS/MAPK, TGF-β/SMAD4, and p53 have been well known since decades (“Vogelgram”, named after Bert Due to simple observations, he made very important discoveries, including Dukes cancer staging system (still in use for colorectal cancer and bladder cancer, although renamed), adenoma-carcinoma sequence (basis for the Vogelgram from Bert Vogelstein), identification of high risk patients (hereditary bowel cancer/polyposis, inflammatory bowel disease) and he was a great advocate of The ‘Vogelgram’ represents a word model, grounded in the linear logic that is typical of this approach.

The original “Vogelgram” (Fearon and Vogelstein, 1990) mapped loss of chromosome 5q, 12p, 18q, and 17p, and mutations on APC, K-RAS, DCC, and p53 in a sequential order of cancer progression, although the importance of mutation accumulation, rather than sequential order, was emphasized.

This is an example of a Vogelgram - multistep cancer progression model (http://www.hopkinscoloncancercenter.org) 2019-06-27 2003-01-23 THE“VOGELGRAM” Cancer develops in a stepwise manner, and each step is associ-ated with changes at the molecular level. 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 new data presented by Cheng et al. provide further evidence for a revision of the classic model of colon cancer evolution (the “Vogelgram”).

In most cases, the disease follows the “classic” adenoma-carcinoma sequence, and underlying genetic alterations of disease driver pathways such as WNT, KRAS/MAPK, TGF-β/SMAD4, and p53 have been well known since decades (“Vogelgram”, named after Bert Nearly three decades after its formulation, the Vogelgram remains a useful model that is often taught to undergraduate biology students. After making these major conceptual advances, Vogelstein’s group has remained at the pinnacle of cancer research, though its focus has evolved with time. The multistep cancer progression model he developed, popularly called the “Vogelgram,” is now taught around the world.

Since metastasis comes late, the cells that migrate to other tissues will have a lot of variety (i.e., be polyclonal), therefore, it will be more difficult to destroy them with single agents.

Bert Vogelstein (born 1949) is Director of the Ludwig Center, Clayton Professor of Oncology and Pathology and a Howard Hughes Medical Institute investigator at The Johns Hopkins Medical Institutions. A pioneer in the field of cancer genomics, his studies on colorectal cancers revealed that they result from the sequential accumulation of mutations in oncogenes and tumor suppressor genes.
