Stem cells as therapeutic targets in colorectal cancer

Colorectal cancer continues to represent a significant burden on public health as the second highest cause of cancer mortality, when men and women are combined, in the US. About 50% of patients either present with late-stage metastatic disease, or develop metastatic recurrences, and ultimately die. In turn, this mortality largely reflects cancer stem cells, tumor-initiating cells that are responsible for cancer progression, drug resistance, recurrence and metastasis. This review summarizes the unique properties of colorectal cancer stem cells, and the emerging strategies by which they can be selectively targeted as a therapeutic approach to eradicating this disease.

Automated summary

Colorectal cancer is the second leading cause of cancer mortality in the US, with 50% of patients presenting with late-stage metastatic disease or experiencing metastatic recurrences, ultimately succumbing to cancer stem cells. Targeting colorectal cancer stem cells is a crucial therapeutic approach for eradicating the disease.
