Why Some Cancers Are More Aggressive Than Others May Come Down to Cell Size
Researchers from Virginia Tech have found that smaller cancer cells with an abnormal number of chromosomes are more aggressive and resistant to treatment. Their study indicates that the size of cancer cells, alongside chromosomal abnormalities, can be a significant predictor of tumor aggressiveness. This discovery may lead to new treatment strategies targeting cancer cell size and behavior.
- ▪Smaller cancer cells with an unusual number of chromosomes are more aggressive than larger ones.
- ▪The study found that tumor growth driven by tetraploid cells relies on the recruitment of non-cancerous stromal cells.
- ▪Experiments showed that smaller tetraploid cells grow faster and are more invasive, regardless of cancer type.

We often associate some cancer types with being more aggressive than others. Patients receiving a glioblastoma (an aggressive brain cancer) or colon cancer diagnosis live in fear of fast-approaching complications. On the other hand, some cancers, like many prostate cancers, often grow slowly (though others can be aggressive), making them easier to treat and rarely fatal.However, why exactly some cancers behave as they do remains a mystery to scientists. To better understand why some cancers are worse than others across the spectrum of different cancer types, researchers from Virginia Tech took a closer look at chromosome numbers and the sizes of cancer cells.Publishing their findings in Cancer Biology and the Proceedings of the National Academy of Sciences, the team describes how smaller…
