Scientists from the University of Michigan have discovered a new way to measure the relationship between nerve density and oral cancer.
They published their findings in a journal called Clinical Cancer Research. This new measurement, called “normalized nerve density,” could help doctors understand how a tumor might grow.
Nerves and Cancer: A Dynamic Interaction
The researchers found that there’s a close relationship between nerves and cancer cells within a tumor. Nisha D’Silva, who led the study, said that they wanted to better understand this interaction.
Different Nerves, Different Roles
The mouth has many different parts, all with different functions. Similarly, nerves in different parts of the mouth have different roles.
For example, the nerves inside the cheek are fewer and have different functions than the nerves on the tongue.
Because of these differences, measuring nerve density (or how many nerves there are in a certain area) in a tumor can be tricky.
If the scientists didn’t account for the normal differences in nerve distribution in the mouth, they could get an inaccurate picture of how aggressive a tumor is.
A New Way to Measure Nerve Density
To solve this problem, the researchers created a new measurement called normalized nerve density.
They used this measurement to study how differences in nerve distribution in the mouth affected tumor growth.
To calculate normalized nerve density, they compared the nerve density in the tumor to the nerve density in the nearby tissue. They also validated their findings using a mouse model.
Findings and Implications
The researchers found that tongue cancers with high normalized nerve density were associated with worse outcomes for patients.
Patients whose tumors were closer to a nerve and had high normalized nerve density also had worse outcomes.
The team also used artificial intelligence to measure normalized nerve density, which could make this new measurement easier to use in clinics.
Potential Benefits
One of the challenges of treating oral cancers is that they tend to come back after treatment.
By understanding which cancers might be more aggressive from the beginning, doctors can treat these tumors more aggressively as well.
The researchers believe that normalized nerve density could help them do just that.
In conclusion, this new measurement of nerve density could be a valuable tool for understanding and treating oral cancers.
