摘要
Colorectal cancer(CRC)is the second deadliest malignancy for both sexes.The BRAF^(V600E)mutation,one of the most common driver mutations in CRC,is known for its poor prognosis due to the increased risk of metastasis.The effect of the BRAF^(V600E)mutation on the tumor microenvironment was the topic of the study reported in World Journal of Gastrointestinal Oncology,with special focus on immune status.The authors presented insightful findings that were exclusively based on macrophage polarity and cytokine levels,without investigating other relevant immune elements.A more comprehensive look into the dynamic immune activity of cancer environments will warrant more meaningful practical findings.In this letter,we discuss other significant immune factors and their possible implications on the tumor microenvironment of BRAF-mutated CRC.
