Finding and Targeting Cancer Stem Cells

Physicians have many ways to kill cancer. They can poison malignant cells with chemotherapy and blast them with radiation. But often the cancer comes back — stronger and more aggressive than before. The reason current therapies don’t always work, according to Max Wicha, is because they don’t kill the most important cells in the tumor. Scientists recently discovered that most types of cancer are driven by specialized cells called cancer stem cells. Wicha wants to develop new therapies that can target and eliminate these cells.

In 2003, Wicha was part of the U-M research team that discovered stem cells in breast cancer — the first cancer stem cells to be found in any human solid tumor. Since then, researchers at the U-M’s Comprehensive Cancer Center have identified stem cells in two of the most deadly types of the disease — pancreatic cancer and head and neck cancer.

The support of the Taubman Research Institute has allowed Wicha’s laboratory to advance its basic studies on cancer stem cells and to launch clinical trials based on its most promising findings. As a result, it is performing some of the first clinical trials in the world designed to target cancer stem cells. Since Wicha has shown that these cells drive tumor growth and metastasis, these novel therapies have the potential to significantly improve the outcome for women with advanced breast cancer.

Furthermore, there is accumulating evidence that similar pathways regulate cancer stem cells in other types of cancer. Thus, the approach and agents that Wicha is developing to target breast cancer stem cells may also prove useful in treating other forms of cancer. His ultimate goal is to initiate additional trials targeting cancer stem cells in other tumor types including bladder, pancreas, lung, ovary, head and neck and brain.
