Solid Tumor Fact Sheet

CIRM funds many projects seeking to better understand solid tumors and to translate those discoveries into new therapies.

Description

Solid tumors include cancers of the brain, ovary, breast, colon and other tissues. Many people believe that one quality solid tumors share is a reliance on cancer stem cells. These cancer stem cells are thought to divide to produce the bulk of the cells that make up the tumor.

The hypothesis suggests that unlike most cells of a tumor, the cancer stem cells divide very slowly and are less likely to be destroyed by chemotherapies that kill the fast-growing tumor cells. The thought is that cancers might recur because the chemotherapy kills the bulk of the tumor, but leaves behind the cancer stem cells that can, over time, form a new tumor.

Stem cell scientists are studying cancer stem cells from solid tumors in the lab to find ways of destroying them. If these cancer stem cells share characteristics that allow them to be destroyed by the same drug, then a single new drug could significantly improve cancer treatment for a range of different cancer types.

Clinical Stage Programs

Stanford University

The Stanford University team has found a protein on the surface of leukemia stem cells that protects those cells from elimination by the patient’s own immune system. They call this protein a “don’t eat me” signal. They will create an antibody therapy that blocks that protein and makes the cancer stem cell available to be attacked and destroyed by the immune system.

Forty Seven Inc.

This company is using the same antibody therapy as in the Stanford trial, this time to fight colorectal or bowel cancer. They are combining their antibody therapy with another antibody-based cancer drug called Cetuximab in hopes of treating patients with colorectal cancer.

University of California, Los Angeles

A team led by scientists at UCLA has identified several potential drugs that kill cancer stem cells from the ovary, colon and brain in the lab dish. They are now testing a drug for the treatment of cancer that works by blocking PLK4, a protein that is important in regulating cell growth, division and death. This protein is important for the survival of the cancer stem cell as well as the rest of the cells in a tumor. It is hypothesized that blocking this protein from working in the tumor may stop or even shrink tumor growth.
