The invasive front of the colorectal carcinoma (CRC) in some cases displays budding, characterized by groups of up to five tumour cells. In 2006, budding was introduced in the Danish Colorectal Cancer Group's (DCCG) and the Danish Society of Pathology and Cytology's (DSPAC) CRC register form. Based on a literature survey, molecular mechanisms that may contribute to budding are reviewed, as is the mode by which this process is registered and its putative clinical significance. Despite diverse modes of budding registration, its significance as a prognostic marker has consistently been substantiated. Additionally, data on budding may prove of value in patient management.
