Omega-3 and Interleukin-8: New Predictors of Chemotherapy Side Effects in Breast Cancer.
Study Highlights:
- A University of California, Irvine study found a link between blood levels of omega-3 fatty acids and the inflammatory biomarker interleukin-8,and increased gastrointestinal (GI) symptoms in breast cancer patients undergoing chemotherapy.
- Higher levels of both biomarkers correlated with increased appetite loss,while elevated interleukin-8 was associated with worsened nausea and vomiting.
- The findings suggest these biomarkers could be used to predict and potentially prevent or mitigate chemotherapy-related GI symptoms.
Inflammation from Two Fronts:
- Chemotherapy drugs, while targeting cancer cells, also trigger intestinal inflammation and disrupt the gut microbiome, further fueling the inflammatory response.
- Tumor cells themselves release inflammatory chemicals during their destruction, adding to the overall inflammation and adverse symptoms,including GI issues.
Predicting and Preventing Side Effects:
- The study analyzed baseline levels of inflammatory markers and GI symptoms in 31 breast cancer patients before and during chemotherapy.
- The researchers believe understanding the predictive value of these biomarkers is crucial for managing and alleviating chemotherapy’s impact on the digestive system.
Future Directions:
- The study focused on breast cancer,but further research is needed to determine if these findings apply to other cancer types.
- The potential for pre-treatment interventions based on these biomarkers to prevent or minimize GI symptoms needs further investigation.
Overall, this study offers promising insights into using predictive biomarkers like omega-3 and interleukin-8 to personalize and improve the chemotherapy experience for breast cancer patients.
