A genetic variant increases liver damage risk in colorectal cancer patients on chemo, especially those of Asian and Latin American descent.
A Mayo Clinic-led study has found that a genetic variant in the PNPLA3 gene increases the risk of liver damage in colorectal cancer patients with liver metastases undergoing chemotherapy.
The variant, more common in people of Asian and Latin American descent, may affect how the liver processes chemotherapy, leading to greater toxicity.
Researchers analyzed data from 551 patients and identified the link as the first evidence of a genetic predisposition to chemo-induced liver injury.
The finding could lead to personalized treatment plans using blood tests and liver monitoring to reduce harm, though further research is needed to confirm its clinical use.
