A standard chemotherapy drug injures surrounding noncancerous cells, which can awaken dormant cancer cells and promote cancer growth, according to a study published today in the journal PLOS Biology.

The methodology is adequate, but limited to preclinical models, so its translation to the clinic remains to be determined.
This study adds to the growing evidence that chemotherapy can damage non-tumor cells that are part of cancers and specifically demonstrates that it can reactivate the growth of dormant tumor cells. Importantly, it describes mechanisms causing this tumor re-emergence in breast cancer that can be counteracted pharmacologically at an experimental level. Its clinical translation is still a question mark.

I have received consulting or advisory fees from Roche, Pfizer, Amgen, MSD, Lilly, and AstraZeneca Daiichi-Sankyo; research funding or grant support for clinical trials from Roche, Pfizer, Amgen, MSD, Lilly, and Daiichi-Sankyo; and travel and accommodation support from Roche, Pfizer, Amgen, MSD, Lilly and AstraZeneca Daiichi-Sankyo. Additionally, I hold a patent in LCOR, EGFR ECD and stock options in Inbiomotion”.

Two things must be taken into account:
- Cancer is a whole; There may be negative interaction with one part, but very positive with another, the absolute balance being positive.
- What is more important: there are studies that have compared giving or not giving taxanes [a type of drugs used as chemotherapy] and the benefits in favor of giving them are very clear.
