Prognostic role of sodium levels in colorectal cancer patients receiving aflibercept plus FOLFIRI.

What is this article about? Colorectal cancer (CRC) is a common and deadly disease. Despite advances in treatment options, the prognosis remains poor for patients who progress beyond the first-line therapy. Antiangiogenic therapy, which targets blood vessel growth in tumors, has become an important treatment approach for metastatic CRC (mCRC). Aflibercept is a drug used in combination with chemotherapy to treat mCRC patients who have progressed after initial treatment. However, there is limited knowledge about factors that can predict the effectiveness of this treatment. This study aimed to investigate the relationship between sodium levels and treatment outcomes in 84 mCRC patients receiving aflibercept and chemotherapy as second-line therapy. What were the results? The results showed that patients with baseline sodium levels of ≥140 mEq/l had significantly longer progression-free survival and overall survival compared with patients with lower sodium levels. This finding suggests that baseline serum sodium levels could serve as a prognostic factor for survival outcomes in mCRC patients treated with aflibercept and chemotherapy. Other factors associated with better survival outcomes included longer survival without disease progression after first-line chemotherapy, receiving maintenance treatment with aflibercept and completing more treatment cycles. What do the results of the study mean? This study highlights the potential significance of serum sodium levels as a predictor of treatment effectiveness in mCRC patients. Further research is needed to confirm these findings and better understand the underlying mechanisms. Evaluating serum sodium levels could be a useful tool in predicting outcomes and improving treatment strategies for mCRC patients.
