Cancer is one of the most feared diseases in the world, and one of the biggest reasons is its ability to spread. When cancer spreads from one part of the body to another, this process is called metastasis. It is responsible for most cancer-related deaths.
However, one of the biggest unanswered questions in science is why some tumors spread while others stay in one place.
A new study from researchers at the University of Geneva in Switzerland may bring us closer to answering this question. The research was published in the scientific journal Cell Reports and focuses on understanding how cancer cells behave and why some become more dangerous than others.
For a long time, people have thought of cancer as a group of cells growing out of control in a random way. But scientists are now starting to see cancer differently. Instead of being completely chaotic, cancer may follow certain patterns. It may even act like a distorted version of normal development processes that happen in the body during early life.
The research team, led by Professor Ariel Ruiz i Altaba, studied colon cancer cells to understand what makes some of them spread. Colon cancer is one of the most common cancers worldwide, and metastasis is a major reason why it becomes life-threatening.
To study this, the scientists took cancer cells from tumors and grew them in the laboratory. They created small groups of cells, called clones, and carefully observed how these cells behaved. Some cells were more likely to move and spread, while others stayed in place.
The researchers then tested these cells in living systems to see how well they could pass through biological barriers and form new tumors in other parts of the body. This helped them understand which cells had a higher ability to spread.
One of the key findings of the study is that cancer spread is not controlled by just one gene or one change in the cell. Instead, it depends on patterns of activity across many genes. These patterns are called gene expression signatures. They show how groups of genes are turned on or off in the cells.
The scientists found that certain patterns of gene activity were strongly linked to whether cancer cells could spread. Interestingly, it was not just about individual cells. The way groups of related cancer cells interacted with each other also played an important role.
After identifying these patterns, the team took the next step. They developed a new artificial intelligence tool called Mangrove Gene Signatures, or MangroveGS. This tool uses information from many genes at the same time to predict how likely a tumor is to spread.
Unlike older methods that rely on only a few markers, this tool looks at hundreds of gene signals together. This makes it more reliable and less affected by differences between patients.
When tested, the AI tool was able to predict cancer spread and recurrence with nearly 80 percent accuracy in colon cancer. This is better than many current prediction methods. Even more promising, the same approach also worked for other types of cancer, including stomach, lung, and breast cancer.
This means the tool could have wide use in the future. Doctors may be able to use it to understand a patient’s cancer more clearly and choose the best treatment plan.
The process is designed to be practical. Doctors can take a tumor sample from a patient, analyze the genetic activity of the cells, and use the AI system to calculate a risk score. This score can help guide decisions about treatment.
For example, patients with a low risk of cancer spread may not need aggressive treatments, which can have strong side effects. On the other hand, patients with a high risk can be monitored more closely and treated earlier.
This approach could also improve clinical trials. By selecting patients more carefully, researchers can test new treatments more effectively and reduce unnecessary participation.
Overall, this study represents an important step toward more personalized cancer care. It shows that cancer behavior is not random, but follows patterns that can be studied and predicted.
However, there are still limitations. The study mainly focused on laboratory-grown cells and models, which may not fully represent the complexity of cancer in real patients. Also, while 80 percent accuracy is promising, it is not perfect. More research and testing in large groups of patients will be needed before this tool can be widely used in hospitals.
In conclusion, this research provides new insight into why cancer spreads and offers a powerful new tool to predict that risk. If further studies confirm these findings, it could lead to better treatment decisions, fewer side effects, and improved survival for many patients.
