BOSTON, February 29, 2024 — Researchers are zeroing in on a surprising player in the fight against chordoma, a rare and aggressive bone cancer: eosinophils, a type of white blood cell often associated with allergies. A new study suggests these cells, typically seen as inflammatory agents, might actually be trying to *help* control tumor growth.
Unlocking the Potential of Eosinophils in Chordoma Treatment

A recent study reveals eosinophils may represent a novel therapeutic target for chordoma, a rare malignant bone tumor.
- Chordoma is a rare cancer that develops in the spine and skull base, affecting roughly one in a million people annually.
- The study, conducted by researchers at Massachusetts General Hospital, found a correlation between eosinophil presence and improved outcomes in chordoma patients.
- Eosinophils appear to release molecules that can inhibit chordoma cell growth and promote anti-tumor immunity.
- Current treatments for chordoma are limited, often involving surgery, radiation, and chemotherapy, with varying degrees of success.
- This research opens the door to exploring new therapies that harness the power of the immune system to combat this challenging cancer.
What if the cells we blame for sniffles and hives could actually help fight cancer? That’s the intriguing question emerging from new research on chordoma, a particularly nasty tumor that often arises near the base of the skull and spine. The study, published recently, challenges conventional wisdom about eosinophils and their role in cancer progression.
The Unexpected Role of Eosinophils
For years, eosinophils have been largely viewed as contributors to inflammation and allergic reactions. However, researchers at Massachusetts General Hospital discovered a significant association between the presence of eosinophils within chordoma tumors and improved patient prognosis. Specifically, patients with higher eosinophil counts tended to have slower disease progression and better responses to treatment.
The team’s investigation revealed that eosinophils release several key molecules within the tumor microenvironment. These include GM-CSF, which attracts other immune cells to the site, and molecules that directly impede the growth of chordoma cells. This suggests that eosinophils aren’t simply infiltrating the tumor by chance, but are actively recruited and participating in an anti-cancer response.
Current Treatment Landscape and Future Directions
Chordoma is a notoriously difficult cancer to treat. Surgery is often the first line of defense, but complete removal can be challenging due to the tumor’s location near vital structures. Radiation therapy is frequently used, but can have long-term side effects. Chemotherapy has shown limited efficacy. As a result, there’s a critical need for new therapeutic strategies.
Q: What makes chordoma so difficult to treat?
A: Chordoma’s location near the skull base and spine, combined with its slow growth and resistance to traditional chemotherapy, makes it a challenging cancer to eradicate, often requiring a multidisciplinary approach.
The findings from this study open up exciting possibilities for developing novel therapies. Researchers are now exploring ways to enhance the activity of eosinophils within tumors, potentially by using drugs that attract more eosinophils to the site or by boosting their anti-cancer functions. This could involve combining existing treatments with immunotherapies designed to harness the power of the immune system.
Implications for Immunotherapy
The study’s results underscore the potential of immunotherapy in treating chordoma. By understanding how eosinophils interact with the tumor and other immune cells, researchers can design more effective immunotherapeutic approaches. This could involve developing vaccines that stimulate an eosinophil-mediated immune response or engineering eosinophils to more effectively target and destroy chordoma cells.
While this research is still in its early stages, it offers a glimmer of hope for patients with this rare and devastating cancer. The unexpected role of eosinophils highlights the complexity of the immune system and its potential to be harnessed in the fight against cancer.
